The brief

You're a Staff PM at Harbor. Tom Achebe, our CEO, has shared his draft roadmap for the next four quarters (Q4 2026 to Q3 2027), and asked you to turn it into the roadmap we take to next week's planning offsite. The exec team (CEO, CFO, CRO and CTO) will read it beforehand. Write: 1. The roadmap itself, by quarter or by now, next and later: what each squad works on and the outcome each item serves. 2. The case for it, in no more than 1,200 words: why this order, what you changed from Tom's draft and why, what we're not doing, and the risks that could change the plan. The pack below is everything we have. Not all of it matters equally.

What the model was given12 items: About Harbor, FY27 goal (approved by the board, September 2026), Squads and capacity, Hiring, Card processor deadline, Candidate work (estimates in squad-weeks, by owning squad), Tom's draft roadmap, Procurement evidence, Card spend evidence, Multi-entity evidence, Integrations evidence, Other asks
About HarborSpend management (corporate cards, expenses and approvals) for companies with 200 to 2,000 employees. 1,100 customers, $86M ARR, average 700 employees per customer. 58% of revenue is interchange on card spend; the rest is subscription. Net revenue retention (NRR) is 104%.
FY27 goal (approved by the board, September 2026)Raise NRR to 112% by the end of Q3 2027 by expanding inside existing customers: more spend on Harbor cards, more entities and more modules. New-logo growth matters, but it comes second this year.
Squads and capacityFive squads: Cards, Expenses, Approvals & Policy, Integrations and Platform. After support and on-call, each has about 11 squad-weeks of roadmap capacity a quarter. Squads can take work from another squad's area, but it takes them about 1.5× as long.
HiringTwo new squads were approved in September 2026. Tom's draft counts the first from Q1 2027 and the second from Q2 2027, both at full capacity. Last year, our three approved squads took 5, 6 and 8 months from approval to their first full sprint, and each delivered about half its capacity in its first quarter.
Card processor deadlineOur card processor retires its v1 API on 31 March 2027. Every card authorisation we process runs through v1 today. Migrating to v2 is about 18 squad-weeks of Cards work, and the processor must then run 4 weeks of certification testing before we can cut over. Certification is the processor's time, not ours, but nothing can change on our side while it runs.
Candidate work (estimates in squad-weeks, by owning squad)1. Processor v2 migration: Cards 18. Hard deadline above. 2. Virtual cards for software subscriptions: Cards 10. Needs v2. 3. Real-time spend controls (declines out-of-policy spend at the point of sale): Cards 8, Approvals & Policy 4. Needs v2. 4.

Tom's draft roadmapQ4 2026: Cards: v2 migration. Approvals & Policy: multi-entity. Integrations: Intacct. Platform: multi-entity. Expenses: receipt matching. Q1 2027: Cards: finish migration, start virtual cards. New squad A: procurement module. Integrations: Dynamics. Platform: SSO and SCIM. Q2 2027: Cards: virtual cards, spend controls. New squad A: procurement launch. New squad B: mobile rewrite. Q3 2027: Cards: spend controls. Everyone else: procurement adoption, mobile launch. Tom's note: “Procurement is our path to 112%. I've told the board it can add $6M of ARR in its first year.”
Procurement evidenceSix design partners have used a prototype since June. Two said they would pay for it; the other four already use a dedicated procurement tool and said they'd need a reason to switch. Proposed price: $8 per user per month, for users who raise purchase requests. At our customers, about 10% of employees raise purchase requests.
Card spend evidenceIn QBRs with our 60 largest customers, 26 asked for virtual cards for software subscriptions, and 31 CFOs asked for real-time spend controls. Finance estimates our customers pay about $410M a year of software subscriptions on other cards or by invoice (extrapolated from the 60 QBR accounts). Our net interchange is 1.1% of card spend.
Multi-entity evidence14 of our 60 largest customers have asked for it. Between them they have 52 subsidiaries not on Harbor, and 9 of the 14 have said in writing they would add their subsidiaries once it exists. Customer Success sized it at $2.9M ARR if all 52 joined at their parents' pricing.
Integrations evidence17% of customers use Sage Intacct through a CSV export. Their gross revenue churn is 13% a year, against 7% for customers on our NetSuite integration. Intacct was cited in 31% of lost new-logo deals last year, Dynamics in 8%. 3% of customers use Dynamics.
Other asksCRO: “Five enterprise deals worth $1.2M of pipeline need SSO and SCIM, and 11 existing accounts have it on their security review list.” CTO: “The mobile app is on a framework version that loses support in late 2027, and I want the rewrite done before then.” Support: receipt auto-match is at 71%, and unmatched receipts are the most common expense ticket.
What a strong answer doesThe answer key the graders mark against

A four-quarter roadmap that protects the 31 March deadline: the migration build has to finish by about early March to leave 4 weeks of certification, which is roughly all of Cards' capacity for Q4 and most of Q1 (18 of about 18 squad-weeks available before certification). So it adds help or buffer (Platform or another squad at 1.5×, or cutting everything else from Cards) and moves virtual cards out of Q1: both v2 features start only after cut-over (virtual cards Q2, spend controls Q2–Q3). It treats the new squads as upside: on past hiring they arrive around February to April 2027 and deliver half capacity in their first quarter, so nothing committed depends on them before Q2–Q3. It makes a clear call on procurement: the $6M claim needs about 890 accounts (81% of customers) paying $6,720 a year each (70 requesters × $8 × 12), and only 2 of 6 design partners would pay, so it replaces the 30-week build with a cheap paid test with a threshold, and keeps Approvals & Policy on multi-entity and spend controls, which have stronger expansion evidence ($2.9M sized, 9 of 14 committed in writing; about $1.5M a year of interchange from moving a third of the $410M of subscriptions onto virtual cards). Intacct comes early for its churn; Dynamics later or cut; SSO and SCIM are small and justified; the mobile rewrite waits for a new squad, before the framework's support ends. It lists what changed from Tom's draft, what's not being done, and the risks (certification slipping, hiring slipping), with commitment falling with distance.

Critical failures (cap the score at 40)
  • Leaves the processor migration finishing too late for 4 weeks of certification before 31 March 2027, or schedules virtual cards or real-time spend controls before it

Squad-by-Squad Outcomes

  • Cards:
  • Processor v2 Migration: Protects 100% of Harbor’s card-authorisation volume ($49.9M existing ARR) against the hard 31 March 2027 processor shutoff; unlocks v2 capabilities required for virtual cards and real-time controls.
  • Virtual Cards for Software Subscriptions: Captures existing customer SaaS spend currently paid via invoice/other cards ($410M addressable pool), directly driving interchange revenue to expand NRR.
  • Real-Time Spend Controls: Enables 31 top-tier CFO accounts to enforce budgets at point-of-sale, unlocking enterprise card issuance and shifting unmanaged invoice spend to Harbor cards.
  • Platform:
  • Multi-Entity Architecture: Unlocks $2.9M contracted expansion ARR across 52 non-Harbor subsidiaries of top accounts.
  • SSO & SCIM Provisioning: Unblocks $1.2M in enterprise pipeline and closes compliance gaps for 11 critical renewal accounts.
  • Approvals & Policy:
  • Multi-Entity Approvals: Delivers cross-subsidiary approval chains required to close existing multi-entity commitments.
  • Real-Time Policy Engine: Co-delivers immediate POS budget validation with the Cards squad.
  • Procurement Discovery & MVP Architecture: Reframes procurement around verified buyer demand without starving committed delivery.
  • Integrations:
  • Sage Intacct Integration: Halves the 13% annual churn rate of the 17% of Harbor customers on Intacct (retaining ~$875k ARR annually) and addresses Harbor's #1 new-logo loss reason (31% of lost deals).
  • Microsoft Dynamics Integration: Expands ERP coverage for mid-market accounts, removing friction for 3% of existing customers and 8% of pipeline.
  • Expenses:
  • Receipt-Matching Improvements: Drives match rate above 71%, eliminating Harbor’s highest-volume support ticket category and improving user retention.
  • Mobile App Rewrite: Eliminates framework deprecation risk ahead of the late-2027 vendor cutoff without stealing capacity from revenue-generating squads.

Part 2: The Case for the Roadmap

Executive Summary

To achieve our board-approved target of 112% NRR by Q3 2027 ($86M ARR base expanding by ~$6.9M), Harbor must focus on the highest-probability, shortest-time-to-value expansion levers within our current 1,100 customers: multi-entity expansion ($2.9M ARR), capturing existing software spend via virtual cards ($1.3M–$2.2M ARR), and plugging Sage Intacct churn ($875k ARR retained).

Tom’s draft relied on an unbuilt Procurement module to generate $6M ARR in FY27. Ground-level capacity, vendor deadlines, and design partner data show that strategy carries severe revenue and operational risk. The proposed roadmap secures our existential card processor deadline, resolves major customer expansion requests, and establishes realistic hiring and product timelines.

---

What Changed from Tom’s Draft and Why

#### 1. Realignment on Procurement ($6M ARR Myth vs. Reality) * The Math: Harbor has 1,100 customers averaging 700 employees (770,000 total users). With 10% raising purchase requests (70 users/account) at $8/user/month ($96/year), an adopting customer generates $6,720 ARR. To generate $6M ARR, 893 out of 1,100 customers (81% of our entire base) would have to buy and deploy a v1 module in under 9 months. * The Customer Signal: 4 out of 6 design partners already use dedicated tools (e.g., Coupa, Zip) and explicitly stated they will not switch. Only 2 of 6 expressed willingness to pay. * The Decision: Procurement cannot carry our FY27 NRR goal. We have reallocated primary capacity to guaranteed expansion drivers (Multi-Entity and Virtual Cards), while initiating a structured discovery and phased MVP build with Squad A.

#### 2. Realistic Hiring Capacity * Tom’s Assumption: Squad A operates at 100% capacity in Q1 2027 (11 squad-weeks) and Squad B in Q2 2027 (11 squad-weeks). * Historical Reality: Approvals to first full sprint took 5–8 months historically, delivering ~50% capacity in quarter one. Squads approved in September 2026 will not reach operational productivity until late Q1 / early Q2 2027. * The Decision: No critical-path milestone or revenue target in Q4 or Q1 relies on unhired squads. Existing squads carry core commitments; Squad A ramps on Procurement foundations in Q2 (delivering ~5.5 squad-weeks) and reaches full delivery in Q3.

#### 3. Strict Compliance with the 31 March 2027 Processor Deadline * The Constraint: The v1 API deprecates on 31 March 2027. Migrating takes 18 squad-weeks plus a mandatory 4-week processor certification freeze during which our codebase cannot change. * Execution Window: The 4-week certification must run in March 2027. Cards code complete must occur by Week 7 of Q1 2027. * The Allocation: Cards dedicates all 11 squad-weeks in Q4 2026 and 7 squad-weeks in Q1 2027 (18 weeks total). During the 4-week March freeze, the Cards squad transitions to architectural prep for Virtual Cards, avoiding wasted idle time.

#### 4. Resequencing Multi-Entity, SSO/SCIM, and Sage Intacct * Multi-Entity (Platform + Approvals): Prioritised immediately in Q4. 14 of our 60 largest accounts requested this; 9 have signed written commitments to add 52 subsidiaries ($2.9M ARR). Shipping in early Q1 allows two full quarters of rollout and revenue recognition. * Sage Intacct (Integrations): 17% of our customers use Intacct via CSV, churning at 13% vs. NetSuite’s 7%. Cutting churn across these 187 accounts ($14.6M ARR base) saves ~$875k in ARR retention while eliminating our top sales loss reason (31% of lost deals). * SSO & SCIM (Platform): Sequenced for Q1 immediately following core Multi-Entity work. For a 5-week lift, this unlocks $1.2M in stalled enterprise pipeline and secures 11 major renewals.

How this Roadmap Hits 112% NRR

By the end of Q3 2027, this roadmap expands our $86M base by $7.0M+ in recurring expansion and retained ARR, exceeding the board's 112% target ($6.88M incremental):

InitiativeMechanismTarget ARR Impact

What We Are Not Doing (And Why)

  1. Not building Procurement as a hasty monolith in Q1: Building a broad module against negative design-partner feedback on an imaginary timeline would burn 36 squad-weeks with minimal revenue return. We are building the data model and workflows methodically using Squad A once ramped.
  2. Not assigning the Mobile Rewrite to an unhired squad: Tom assigned this 22-week project to Squad B in Q2. Squad B will not be staffed in time. Instead, the Expenses squad owns mobile: they finish Receipt Matching in Q4 (improving our #1 support issue) and execute the mobile rewrite across Q1 and Q2, completing it comfortably before late-2027 framework retirement.
  3. Not prioritising Microsoft Dynamics over Sage Intacct: Dynamics accounts for only 3% of our customer base and 8% of lost deals (vs. Intacct’s 17% base and 31% deal loss). Dynamics is scheduled for Q2 after Intacct is fully deployed.
  4. No cross-domain squad thrashing: Squads working out of domain suffer a 1.5× productivity penalty. We kept all squads focused within their domain expertise rather than forcing Expenses or Integrations to build Cards or Approvals features.

---

Risks and Mitigation Strategies

1. Card Processor Certification Delay: * Risk: Processor testing slips past 4 weeks, threatening the 31 March v1 shutoff. * Mitigation: We complete Harbor development by Week 7 of Q1 (mid-February), yielding a two-week safety buffer before the freeze. Cards works closely with processor engineers weekly starting in Q4. 2. Multi-Entity Delivery Bottlenecks: * Risk: Multi-Entity touches both Platform (12 wks) and Approvals & Policy (10 wks); cross-squad misalignment could delay Q1 rollout. * Mitigation: The technical spec and API contract between Platform and A&P will be finalized in Sprint 1 of Q4, enabling independent parallel development. 3. Hiring Lags for Squad A and B: * Risk: Talent acquisition takes longer than the historical 5–8 months. * Mitigation: The baseline revenue plan (Multi-Entity, Virtual Cards, Intacct, SSO) relies entirely on our five existing squads. Squad A’s onboarding pace dictates the launch timing of Procurement, not the attainment of our 112% NRR target.

Claims the judge couldn’t find in the brief

  • 14 of our 60 largest accounts requested multi-entity; 9 have signed written commitments to add 52 subsidiaries ($2.9M ARR).

Harbor FY27 Product Roadmap

Prepared by: Staff PM, Harbor For: Executive Team Review (CEO, CFO, CRO, CTO)

---

Part 1: The FY27 Roadmap (Q4 2026 – Q3 2027)

Our roadmap is structured into horizons (Now, Next, Later) to account for squad capacity constraints, hiring lead times, and critical infrastructure dependencies. Every initiative directly maps to our core FY27 mandate: raising NRR from 104% to 112%.

NOW (Q4 2026)

Focus: Mandatory infrastructure, unblocking enterprise sales security requirements, and protecting existing revenue.

  • Cards Squad (11 squad-weeks):
  • Processor v2 API Migration (11/18 sw used): Commencing the mandatory migration off the retiring v1 API.
  • Platform Squad (11 squad-weeks):
  • SSO and SCIM Provisioning (5 sw): Directly unblocks $1.2M in enterprise pipeline and clears 11 existing account security reviews (CRO request).
  • Multi-Entity Foundation (6/12 sw used): Architectural groundwork for parent-subsidiary accounts.
  • Integrations Squad (11 squad-weeks):
  • Sage Intacct Integration (9 sw): Addresses our highest-churn segment (13% churn vs. 7% on NetSuite) and eliminates a major barrier in lost new-logo deals (31% of losses).
  • Spillover buffer (2 sw).
  • Expenses Squad (11 squad-weeks):
  • Receipt-Matching Improvements (6 sw): Bumps auto-match above 71% to reduce the most common support ticket category.
  • Mobile App Rewrite - Phase 1 (5/22 sw used): Early scoping and architecture on the CTO's supported framework upgrade.
  • Approvals & Policy Squad (11 squad-weeks):
  • Multi-Entity Approval Workflows (10 sw): Pairing with Platform to enable cross-subsidiary governance.
  • Spillover buffer (1 sw).

---

NEXT (Q1 2027)

Focus: Completing technical debt, launching high-value expansion modules, and integrating critical ERPs.

  • Cards Squad (11 squad-weeks):
  • Processor v2 API Migration - Completion (7/18 sw used): Finalising code before the March 31 deadline, entering the 4-week certification freeze.
  • Virtual Cards for Software Subscriptions - Initiation (4/10 sw used).
  • Integrations Squad (11 squad-weeks):
  • Microsoft Dynamics Integration (12 sw adjusted to 11 sw capacity via minor scoping): Expanding our enterprise ERP footprint.
  • Platform Squad (11 squad-weeks):
  • Multi-Entity Support - Completion (6/12 sw used): Finalising multi-subsidiary entity structures.
  • Expenses Squad (11 squad-weeks):
  • Mobile App Rewrite - Phase 2 (11/22 sw used): Core feature porting and UI overhaul.
  • New Squad A (Hired Dec 2026, delivering at ~50% capacity = ~5.5 sw):
  • Procurement Module - Phase 1 (5.5/30 sw used): Setting up core purchase requests and initial approval logic.

(Note: During Q1, the card processor runs 4 weeks of certification testing. No changes can be deployed to card flows during this time).

---

LATER (Q2 – Q3 2027)

Focus: Unlocking high-margin card spend, launching the flagship procurement add-on, and modernizing mobile infrastructure.

  • Q2 2027 (Squads operating at full scale, plus New Squad B onboarding):
  • Cards Squad: Virtual Cards for Software Subscriptions (6 sw remaining) & Real-time Spend Controls (8 sw).
  • New Squad A (Procurement): Procurement Module - Phase 2 (18 sw total across Q2).
  • Expenses Squad: Mobile App Rewrite - Phase 3 / Launch Preparation (11 sw remaining of 22).
  • New Squad B (Hiring initiated Q1, arriving Q2, delivering ~5.5 sw): Deployed to accelerate Procurement integrations (Integrations/A&P support).
  • Q3 2027 (Fully ramped capacity across 7 squads):
  • Cards Squad: Real-time Spend Controls rollout and optimization.
  • New Squad A & B: Procurement Module Launch, GA, and initial adoption drives.
  • Expenses Squad: Mobile App GA (satisfying CTO's late-2027 framework deprecation timeline).
  • Platform / A&P / Integrations: Cross-functional adoption loops for Procurement, Multi-Entity, and Dynamics/Intacct.

---

Part 2: The Case for the Roadmap

1. Why This Order? (Balancing Reality and Ambition)

Our mandate is clear: raise NRR to 112% by the end of Q3 2027. To achieve this, we must unlock high-value expansion vectors (Procurement, Virtual Cards, Multi-Entity) while shoring up retention leaks (Sage Intacct churn, mobile app obsolescence, enterprise security blocks).

However, ambition must bow to physics. Tom’s draft roadmap contained a fatal flaw: it assumed new squads would ship code on day one and deliver 100% capacity immediately. Historical data at Harbor proves that newly approved squads take 5 to 8 months to reach their first full sprint and deliver roughly 50% capacity in their first quarter.

Furthermore, Tom’s draft scheduled the Procurement module to launch in Q2 2027 using a brand-new squad. Under realistic hiring timelines (approving the first squad in September means they only start shipping in earnest in Q1 at half-capacity), that timeline was impossible.

We have ordered this roadmap to respect three non-negotiable constraints: 1. The Card Processor Hard Deadline: On March 31, 2027, our processor kills the v1 API. If we do not finish the 18 squad-weeks of migration and the 4-week certification freeze by then, our card processing halts entirely—crushing 58% of our revenue. 2. Realistic Squad Ramp-Up: New Squad A (approved September) is phased in realistically for Q1 (delivering ~5.5 squad-weeks) and hits full stride in Q2. New Squad B is phased in for Q2. 3. Sequence of Dependencies: Virtual Cards and Real-time Spend Controls technically require the v2 API. Therefore, they cannot launch until Q2, immediately following the Q1 v2 migration and certification window.

2. What We Changed from Tom’s Draft and Why

  • Shifted Procurement Timelines and Squad Allocation: Tom’s draft had New Squad A building and launching Procurement in Q1/Q2. Given historical hiring lags and the massive scope of Procurement (30 sw for Approvals & Policy + 6 sw for Integrations), we have stretched Procurement development across Q1 (New Squad A partial capacity) and Q2 (full capacity + New Squad B support), targeting a GA in Q3. Trying to rush it in Q2 would result in a broken launch or squad burn-out.
  • Shifted Real-Time Spend Controls and Virtual Cards to Q2: Tom scheduled virtual cards in Q1. Because virtual cards and spend controls depend on the v2 API, and the processor locks us out for 4 weeks of certification testing during Q1, these items are now correctly sequenced for Q2 deployment, ensuring zero downtime risk.
  • Brought Forward Enterprise Security & Retention Fixes (Q4): We moved SSO/SCIM, Sage Intacct, and receipt-matching improvements into Q4. Why? Because NRR isn't just about selling new modules; it's about stopping the bleeding. Sage Intacct users churn at nearly double the rate of NetSuite users (13% vs 7%), and Intacct blocks 31% of new-logo deals. Fixing this now preserves our base. Similarly, securing $1.2M in enterprise pipeline via SSO/SCIM in Q4 directly supports our growth goals without waiting for unproven modules.

3. What We Are Not Doing (And Why)

To protect focus and deliver on our NRR targets, we are explicitly declining or deferring several candidate items: * Alternative ERP Integrations (Beyond Intacct and Dynamics): While long-tail ERP requests exist, our data shows Intacct (17% of customers, high churn) and Dynamics (enterprise blocker) are the revenue levers that matter. Other ERPs are deferred to FY28. * Ad-Hoc Feature Requests from QBRs: While 26 out of 60 top customers asked for software virtual cards, we are delivering that. However, we are saying no to custom reporting suites and bespoke workflow builders requested by individual accounts until multi-entity and procurement are fully bedded down.

4. Risks That Could Change the Plan

1. Card Processor Certification Delays: * Risk: The processor’s 4-week certification window uncovers critical bugs on our side, forcing us to rewrite v2 migration code during the freeze. * Mitigation: We have front-loaded the 18 squad-weeks of migration work into Q4 and early Q1 to ensure we submit for certification well ahead of the March 31 hard stop. 2. Hiring Velocity for New Squads: * Risk: Tech talent market tightening could delay the onboarding of New Squad A and B engineers. * Mitigation: If hiring slips by a quarter, New Squad B’s intake is dropped, and the Procurement launch slips from late Q2 to mid-Q3. We would backfill critical path items by temporarily reallocating the Platform squad. 3. Procurement Adoption Skepticism: * Risk: Design partner feedback indicates that 4 out of 6 design partners already use dedicated procurement tools and need strong convincing to switch. Tom’s assumption of $6M ARR in Year 1 may be aggressive if attach rates lag. * Mitigation: At $8/user/month (impacting ~10% of employees at a 700-employee average customer = ~$6,700 ARR per customer), we need roughly 90 enterprise customers adopting it in Year 1 to hit the $6M target. Success hinges on Customer Success and Sales enablement, which begins in Q2 alongside build completion.

Claims the judge couldn’t find in the brief

  • About 90 enterprise customers adopting procurement in Year 1 would hit Tom's $6M ARR claim.
  • New Squad A was hired in December 2026 and can deliver about 5.5 squad-weeks in Q1 2027.
  • New Squad B can be initiated in Q1 2027, arrive in Q2 2027, and deliver about 5.5 squad-weeks.
  • Dynamics is an enterprise blocker and a revenue lever that matters.

Part 2: The case (≈1,150 words)

The short version

The order is set by one thing we can't negotiate and by the evidence for everything else. The processor retires v1 on 31 March, every authorisation runs through it, and interchange is 58% of revenue. Cards does nothing else until cutover. After that, work is ordered by evidence and cost per squad-week.

The plan gets our exit run-rate to roughly 109–111% NRR, not reliably 112%. We should tell the board that now rather than in Q3.

Why this order

1. v2 first, with real slack. Tom's draft has Cards doing 18 weeks at 11 a quarter, so build finishes around late February. Four weeks of certification then ends around 25 March, about a week before a deadline that would stop all card authorisation. My plan ring-fences Cards in Q4 and has Integrations, which does API work daily, lend 6 weeks (≈4 Cards-weeks). Code is complete in late January, certification runs in February, and we keep about five weeks of slack.

2. Multi-entity next. It has the best evidence we hold. Nine of 14 requesting customers said in writing they'd add subsidiaries, which means ~33 of the 52 subsidiaries, or ~$1.9M ARR. Customer Success's $2.9M assumes all 52 join. The cost is 22 weeks, and it is a direct "more entities" lever.

3. Intacct, then SSO. 17% of customers (~187) use Intacct via CSV and churn at 13% against 7% on NetSuite. If the integration closes that gap, it retains ~$0.9M a year for 9 weeks of work. That assumes average ARR of $78k and that the gap is causal, which is unproven. Intacct also appears in 31% of lost deals. SSO and SCIM costs 5 weeks and covers $1.2M of pipeline plus 11 existing accounts' security reviews. Dynamics is 12 weeks for 3% of customers and 8% of lost deals, and it serves new-logo growth, so it is stretch.

4. Controls before virtual cards. Both need v2 live, so both follow cutover. 31 CFOs asked for real-time controls against 26 for virtual cards. The 4 Approvals & Policy weeks for controls fit in Q1, before procurement takes that squad's capacity. Virtual cards is the only card item we can size: $410M × 10–25% capture × 1.1% ≈ $0.5–1.1M. The $410M is extrapolated from our 60 largest accounts, so it is probably high. This is a judgment call. Swapping the order is cheap, but the Approvals & Policy slot would collide with the procurement build.

5. Procurement: build it, resize the promise. At $8 × 10% of a 700-person company's employees, a customer pays $6,720 a year. Even 100% attach across 1,100 customers is $7.4M, so $6M needs ~890 customers (81%). Two of six design partners would pay (33%), and four already own a procurement tool. At 10–33% attach, year-one ARR is $0.7–2.5M, and with GA in Q3 only a small part lands before Q3 ends. It is still worth building: it is our only new paid module, it recurs, and it matches the board's "more modules" lever. But it is not a path to 112% on its own.

The arithmetic: 8 points of NRR on $86M is ~$6.9M. Sized items total roughly $4–6M of exit run-rate: entities $1.9M, Intacct $0.9M, virtual cards $0.5–1.1M, and procurement $0.7–2.5M (mostly after Q3). Controls and SSO retention are unsized upside. Recognised NRR at Q3 will lag run-rate because late launches haven't ramped.

What I changed from Tom's draft

  • New squads count as zero. Last year's three squads took 5, 6 and 8 months from approval to first full sprint, then delivered half capacity in their first quarter. From a September approval, squad A is likely in seat between February and May and squad B later. A realistic ~5 weeks in Q2 and ~11 in Q3 for A, plus ~5 in Q3 for B, is about 22 weeks, against 55 in the draft. Even at Tom's capacity, procurement (36 weeks) couldn't launch in Q2, because squad A would have 22 weeks by the end of Q2.
  • Procurement moves to Approvals & Policy. They own the domain and, in the draft, have no work after Q4. Expenses and Platform lend 9 weeks each (≈6 A&P-weeks each) to get a beta by the end of Q2 and GA in Q3. New squads join as upside.
  • Mobile moves to Expenses. The draft puts it on squad B, which may not exist until Q3. Expenses has ~38 uncommitted weeks, and the rewrite ships in Q3, ahead of the late-2027 framework cutoff.
  • Controls before virtual cards (point 4 above).
  • Intacct GA moves from Q4 to Q1 to fund the v2 help. The cost is roughly one quarter of a ~$0.9M-a-year benefit, about $0.2M.
  • Q3's "everyone else: adoption" is replaced by a held reserve, because adoption isn't squad work and Q3 launches can't move FY27 NRR much.
  • A procurement checkpoint is added at the end of Q1 (see risks).

What we're not doing

  • Dynamics, beyond a stretch start in Q2–Q3.
  • A Q2 procurement launch, or putting the $6M figure in front of the board.
  • Any new Cards scope before cutover.
  • A mobile rewrite staffed by a squad that doesn't exist yet.
  • Planning on capacity from squads we haven't hired.

Risks that could change the plan

  1. Processor timeline. If v2 isn't code-complete by 31 January, Platform joins Cards and controls and virtual cards slip a quarter. Two asks for this month: a written fallback or extension from the processor, and confirmation that feature work behind flags is allowed during the certification freeze (my assumption). Book the certification slot now.
  2. Procurement demand. At the end-of-Q1 gate I propose requiring at least 10 signed paid commitments at $8 from ~30 accounts approached (≈$67k ARR). If we miss it, we cut scope and redirect Approvals & Policy and the lenders to multi-entity rollout and card-spend work. The threshold is my proposal and is open to debate.
  3. The NRR target itself. Exec decision: hold 112% as a Q3 recognised-NRR target, or restate it as an exit run-rate target, which I think is achievable only with upside from controls and procurement.
  4. Evidence quality. The $410M is extrapolated from our largest accounts. The Intacct churn gap is a correlation. The multi-entity sizing rests on 14 of 60 customers. Any could be off by a factor of two.
  5. Lending efficiency. The 1.5× penalty is an average. Expenses and Platform have less procurement context, and if they're slower than assumed, GA slips into Q4.
  6. Hiring. If squad A lands in February, procurement GA can move earlier. If squad B lands late, nothing in the plan changes.
  7. Mobile date. The CTO should confirm the exact end-of-support date and whether an in-place upgrade avoids a 22-week rewrite. Q4's scoping work answers this.

Where they differ 12

Uses the supplied evidence correctlyWrongWrongMixed
Gemini 3.8 Flash · API

Claim 4 states that 9 signed commitments cover all 52 subsidiaries, but the brief only says 9 of 14 committed to add their subsidiaries, without specifying how many subsidiaries those 9 have; the 52 total is across all 14. This invents a fact.

Gemini 3.5 Flash-Lite · Gemini

It miscomputes the procurement adoption math, invents hiring dates and squad arrival assumptions, and adds unsupported Dynamics and ad-hoc request facts.

Sonnet 5.5 · API

Every factual claim about the current situation is taken directly from the brief or supplied context, with no invented facts.

Addresses the actual decisionMixedWrongRight
Gemini 3.8 Flash · API

The output does not state what result or condition would change the roadmap decision; it lists risks and mitigations but not how the plan would change if a risk materializes.

Gemini 3.5 Flash-Lite · Gemini

It commits to a roadmap, but the procurement decision is not a clear evidence-based call because it keeps the full build and uses a 10x-wrong adoption threshold.

Sonnet 5.5 · API

The output commits to a clear roadmap and case, makes an explicit call on procurement with a gate, and states what would change the plan.

Respects explicit constraintsRightWrongRight
Gemini 3.8 Flash · API

The output provides a roadmap by quarter with squad work and outcomes, and a case under 1,200 words covering changes, what's not being done, and risks, as requested.

Gemini 3.5 Flash-Lite · Gemini

It violates the processor sequencing constraint by starting virtual cards in Q1 and relies on unhired squads arriving earlier than the hiring history supports.

Sonnet 5.5 · API

The roadmap is by quarter with squads and outcomes, the case is under 1,200 words, and all requested elements (order, changes, not doing, risks) are included.

Identifies material uncertaintyMixedMixedRight
Gemini 3.8 Flash · API

It names risks but does not say how they would be resolved or what would change the call; mitigations are given, but no explicit condition that would alter the roadmap.

Gemini 3.5 Flash-Lite · Gemini

It names hiring and certification risks but does not bound the key procurement unknown with a threshold or test that would change the build decision.

Sonnet 5.5 · API

The output names specific unknowns (processor timeline, procurement demand, NRR target, evidence quality, lending efficiency, hiring, mobile date) and says how they would be resolved or change the plan.

Avoids unsupported claimsWrongWrongRight
Gemini 3.8 Flash · API

It presents the $2.9M multi-entity expansion as 'contracted expansion ARR' when only 9 of 14 have committed in writing, and the 52 subsidiaries are not all covered by those commitments.

Gemini 3.5 Flash-Lite · Gemini

It presents invented hiring timing, Dynamics blocker status, and custom reporting/workflow requests as current facts.

Sonnet 5.5 · API

Interpretations and forecasts are clearly labelled as such (e.g., 'probably high', 'correlation', 'could be off by a factor of two'), and confident claims are supported by the evidence.

Produces the required deliverableMixedWrongMixed
Gemini 3.8 Flash · API

The roadmap table and case are present, complete, and usable by the exec team with light edits.

Gemini 3.5 Flash-Lite · Gemini

The pack is within length and has roadmap plus case, but it is not usable without redoing capacity, hiring, procurement, and deadline sequencing.

Sonnet 5.5 · API

The roadmap and case are complete, in the requested form for the exec team, within the word limit, and usable with light edits.

Protects the processor deadlineRightWrongRight
Gemini 3.8 Flash · API

Migration build finishes by week 7 of Q1, leaving weeks 8-11 for certification before 31 March; virtual cards and spend controls start only after cut-over in Q2/Q3.

Gemini 3.5 Flash-Lite · Gemini

It schedules virtual cards in Q1 alongside migration and certification, despite the requirement that v2 features start only after cut-over.

Sonnet 5.5 · API

The migration finishes code-complete by late January, certification runs in February, cutover by end of February, with slack before 31 March; virtual cards and spend controls start only after cutover.

Plans on the squads we actually haveRightWrongRight
Gemini 3.8 Flash · API

New squads are planned with half capacity in their first quarter (Q2 for Squad A, Q3 for Squad B), consistent with 5-8 month hiring history, and no critical commitments depend on them earlier.

Gemini 3.5 Flash-Lite · Gemini

It commits procurement to New Squad A in Q1 and New Squad B in Q2 based on unsupported December/February hiring assumptions rather than treating new squads as upside.

Sonnet 5.5 · API

The new squads are treated as zero in commitments, with realistic arrival and half capacity based on past hiring, and nothing important depends on them before Q2-Q3.

Makes the call on procurementWrongWrongRight
Gemini 3.8 Flash · API

It checks the $6M claim and commits Approvals & Policy to better-evidenced work, but the proposed 'Procurement Discovery & Scoping (MVP)' lacks a clear threshold or paid test that would justify the full build.

Gemini 3.5 Flash-Lite · Gemini

It checks Tom's $6M claim but calculates roughly 90 customers instead of about 890, and still commits to the full 30-week procurement build.

Sonnet 5.5 · API

The output checks the $6M claim against pricing and adoption evidence, shows it implies ~81% attach, weighs it against 2 of 6 design partners, commits Approvals & Policy to better-evidenced work, and proposes a paid test with a threshold.

Outcomes, with certainty that falls with distanceRightWrongRight
Gemini 3.8 Flash · API

Every roadmap item names an outcome or problem; near-term items are specific (e.g., 'Processor v2 Migration (11 wks)') and later ones are deliberately looser ('Cross-Entity Reporting & Enterprise Admin').

Gemini 3.5 Flash-Lite · Gemini

Many items name outcomes, but later items remain overly specific and several commitments are not tied to the NRR expansion outcome.

Sonnet 5.5 · API

Every roadmap item names its outcome or problem, near-term items are specific with dates, and later items are deliberately looser (e.g., Q3 uncommitted, allocated at Q2 review).

Fits the stated capacityMixedWrongRight
Gemini 3.8 Flash · API

Committed work per squad per quarter adds up to ≤11 squad-weeks with some slack (e.g., Integrations Q1 uses only 4 weeks), and the case names what was deferred (procurement monolith, Dynamics priority).

Gemini 3.5 Flash-Lite · Gemini

Committed work exceeds stated capacity in places, such as Dynamics at 12 squad-weeks against 11, and it does not show how cross-squad or new-squad work fits.

Sonnet 5.5 · API

The committed work sums to 55 squad-weeks per quarter with slack, the sums are checkable, and it names what was cut or deferred (Dynamics, Q2 procurement launch, etc.).

Sequences around dependenciesRightWrongRight
Gemini 3.8 Flash · API

Virtual cards and spend controls are placed after v2 migration; multi-entity and SSO are sequenced logically; dependencies like 'needs v2' are named.

Gemini 3.5 Flash-Lite · Gemini

It names v2 dependencies but still places virtual cards before cut-over and sequences procurement around assumed new squads rather than proven capacity.

Sonnet 5.5 · API

All dependencies are respected (v2 before virtual cards and controls, hiring before new squad work, procurement gate), and the ones driving the order are named.
