Build a roadmap

Part 1: Roadmap, Q4 2026 to Q3 2027

Planning basis: Five existing squads at 11 squad-weeks a quarter (55 a quarter). The two new squads are counted as zero in the commitments (see the case). Lending between squads is costed at 1.5×. Figures in brackets are squad-weeks of the named squad.

Q4 2026: Protect the card rail, start entities

Q1 2027: Cut over, ship entities, start controls

Q2 2027: Virtual cards, procurement beta

Q3 2027: Launch and land

About 60 of 220 squad-weeks are deliberately uncommitted, mostly in Q3.

---

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.

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.

Harbor Roadmap, Q4 2026 to Q3 2027

Pre-read for the planning offsite. Prepared from Tom's draft.

Part 1: The roadmap

Planning assumptions - Each existing squad has 11 squad-weeks of roadmap capacity a quarter. Work done in another squad's area costs 1.5×. - The two new squads are planned at the dates our history supports, not the approved dates. Last year's squads took 5 to 8 months from approval to their first full sprint. - Squad A: 0 weeks in Q1, about 5 in Q2 (half capacity), about 11 in Q3. - Squad B: 0 weeks in Q2, about 5 in Q3. - Nothing committed depends on either new squad. - The fiscal year runs Q4 2026 (Oct to Dec) through Q3 2027 (Jul to Sep).

Items, outcomes and key dates

NRR bridge: what this plan plausibly delivers by end of Q3 2027

Moving NRR from 104% to 112% needs about $6.9M of additional net expansion (8 points of $86M).

---

Part 2: The case for it

The short version

Tom's draft has the right ingredients. It does, however, have three problems:

1. No buffer on the processor deadline. The migration has no room to slip against a date that could stop every card authorisation.
2. Key work sits on squads we won't have. Procurement and the mobile rewrite depend on new squads that history says won't exist at full capacity until Q3 at the earliest.
3. Procurement can't carry the goal. It is expected to deliver the NRR target, but the evidence doesn't support $6M and the timing puts almost none of it inside the measurement window.

This plan protects the deadline first. It then sequences the levers with the strongest evidence so they land early enough to count. Even so, product alone likely gets us to 107% to 110%, not 112%. The exec team should know that now, not in Q3.

Why this order

1. The processor migration comes first, with buffer.

Every authorisation runs through v1, so a missed cutover puts most of our revenue at risk. On Tom's draft: - Cards alone finishes the 18 weeks around late February. - The 4-week certification then ends in the last days of March. - That leaves under a week of slack, with December holidays not counted and no room for a failed certification.

Lending 5 Platform weeks in Q4 changes this: - Code complete moves to about 31 January. - Cutover lands around 1 March. - We have roughly four weeks of buffer.

This also means virtual cards can't "start in Q1" as the draft says. During certification nothing on our card stack can change. Cards will do design and sandbox work in Q1 and start production work after cutover.

2. Multi-entity and virtual cards next, because they have the best evidence and they land in time.

NRR is measured at the end of Q3, so anything launching after about June barely counts. Our two strongest levers are: - Multi-entity: 9 customers have committed in writing to add subsidiaries, which is about $1.5M to $2.9M. - Virtual cards: a $4.5M ceiling. 26 of our 60 largest customers asked for them.

Multi-entity ships in February. Virtual cards ship in May. Real-time spend controls follow in July because they share the Cards squad. They matter to 31 CFOs, but we haven't sized them.

3. Retention work runs in parallel, because it is cheap.

• Intacct: 9 weeks of work. It addresses a segment churning at nearly twice our NetSuite rate and appears in 31% of lost deals. The integration only reduces churn if customers actually move off CSV, so I added a Q1 migration push with CS.
• SSO and SCIM: 5 weeks of work. It protects 11 accounts and unblocks $1.2M of pipeline.

4. Procurement is real but gated, and it is not the FY27 lever.

What I changed from Tom's draft, and why

1. Migration buffer. Platform lends 5 weeks in Q4. The cost is that multi-entity moves from December to February. I think that trade is clearly right, because the downside of a missed cutover is existential.

2. New squads planned realistically. - Squads approved in September reach their first full sprint between February and May, based on last year's 5 to 8 months. - Each then runs at half capacity for a quarter. - Squad A realistically gives about 5 weeks in Q2. Squad B gives nothing before Q3. - I've kept every committed item on the existing five squads. The new squads are upside.

3. Procurement moved to Approvals & Policy and gated. - A&P owns the domain, has capacity after multi-entity, and was left without work in the draft. - Build starts in Q1. At the end of March we need signed paid-pilot commitments from about 10 customers beyond the two design partners, or we redirect A&P. - GA lands around September. If Squad A arrives on time, it accelerates the work.

4. The $6M procurement figure needs resetting with the board. - At $8 per user per month and 10% of our ~770,000 employees raising requests, the ceiling is about $7.4M a year if every customer adopts. $6M therefore implies about 81% adoption. - Only 2 of 6 design partners said they'd pay. The other four already use a dedicated tool. - At a one-in-three adoption rate, procurement is worth about $2.5M at full run-rate, reached over years, and less than $0.3M inside FY27. - I recommend Tom and the CFO correct this at the next board touchpoint, before the board starts tracking it.

5. Mobile rewrite moved to Expenses, starting in Q4. - Expenses owns the app and the draft left it idle after Q4. - The rewrite finishes by May, and the old app is retired by September. - This gives the CTO's deadline real margin. Leaving it on Squad B would risk missing it.

1. Spend controls now include the A&P work (4 weeks). The draft omitted this.

1. Dynamics moves from Q1 to May. The Intacct customer migration goes first, because Intacct matters roughly five times more by customer count and lost deals.

What we're not doing

• Not claiming procurement drives FY27 NRR. We are also not building past the March gate without paid commitments.
• Not starting virtual cards or anything else on the card stack before cutover.
• Not putting any deadline-critical or NRR-critical work on unhired squads.
• Not adding new-logo-only features beyond Intacct, Dynamics and SSO, which also serve retention. New logos come second this year, as the board set.
• Not filling the Q3 reserve on Platform and Integrations. That slack absorbs migration fallout, integration hardening and new-squad onboarding. If the migration goes cleanly, we can release it to card-spend adoption work at Q2 planning.

Risks that could change the plan

1. Certification fails or needs a second round. A re-run would consume the entire buffer. - Book the certification slot now. - Run a pre-certification dry run in January. - Ask the processor in writing for a contingency extension and an emergency-fix protocol for the freeze window. - If code complete slips past mid-February, pull more Platform capacity immediately.

2. The $410M software-spend figure is extrapolated from our 60 largest accounts. Smaller customers may put proportionally less software spend on cards. - In Q4, validate it with AP data from about 20 mid-sized customers. - If it halves, virtual cards is worth about $0.4M to $0.8M in window and spend controls rises in priority.

1. Multi-entity conversion comes in below the written commitments. CS should agree subsidiary onboarding plans with the 9 customers in Q1, before the feature ships.

1. Real-time spend controls sit on the authorisation path. A latency problem could cause false declines. Platform supports this work in Q3, and we should launch in stages.

1. Hiring slips further. This doesn't threaten committed dates, but procurement would stay in Q3 and our adoption capacity shrinks.

1. The procurement gate fails. A&P redirects to deeper spend controls and multi-entity policy features, both of which feed card spend.

1. The mobile framework end-of-support date is only "late 2027". The CTO should confirm the exact date.

Decisions we need at the offsite

1. Approve Platform's Q4 loan to Cards, accepting that multi-entity moves to February.
2. Agree the board message on procurement, and the gate criteria behind it.
3. Close the NRR gap. This plan lands about 107% to 110%. Closing the remaining $1.5M to $4M needs commercial levers the CRO and CFO own, such as CS-led card activation, packaging and pricing, and a multi-entity sales motion beyond the 9. Otherwise we tell the board now that 112% is a stretch.
4. Authorise the processor extension request.
