How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

  1. Competes with what customers really choose

    Does the analysis treat the status quo (spreadsheets, manual work, doing nothing) as a competitor, and draw at least one implication from where competitors are investing rather than only from today's features?

    Passes when Analyses the status quo, strengths included, and gives a direction-of-travel insight that affects the recommendation.

  2. Separates what a rival can copy

    Does the analysis separate advantages a well-funded competitor could copy (features, price, being first) from ones it couldn't easily (switching costs, networks, relationships), and build the response on the latter?

    Passes when Names which advantages are copyable and which aren't, with evidence, and anchors the response in the durable ones.

The brief

You're the PM for growth at Tallybook. Our CEO, Dan Whitlock, wants a feature-by-feature comparison against Billfront and a plan to match everything they have by Q2 (his note is below). Write him a competitive analysis of no more than 900 words: who we really lose to, where Billfront is a real threat and where it isn't, where it's heading, and what we should do instead of (or as well as) matching it. The files are attached.

# Billfront (public pages, September)

- Pricing: $12/month Starter, $29/month Pro (multi-currency, live FX rates), $59/month Team.
- Homepage: "Invoicing for global teams". Case studies: three agencies, one consultancy.
- Recent launches: multi-currency invoicing (March), client portal (June).
- Job posts: 4 engineers for "global payments", 2 for "agency workflows".
What a strong answer doesThe answer key the graders mark against

Shows from the deals file that the biggest competitor is no decision: of 46 lost deals, 25 ended with the prospect staying on spreadsheets or never switching, 17 went to Billfront and 4 to Xero invoicing. Billfront's wins are concentrated in multi-currency agencies (11 of its 17), on a specific gap (invoicing in several currencies with live rates); elsewhere it won only 6 deals, mostly on price. Agencies are a small segment (240 customers at about $46 a month, about $11,000 MRR, against about $64,000 from freelancers and $74,000 from small businesses), and Billfront is heading further into them (global payments and agency workflow hiring). Recommends against matching everything: fix switching friction for small businesses who 'didn't get round to it' (imports, setup help, accountant tie-ins), make a deliberate call on multi-currency (build it if agencies matter strategically, or cede the segment), and keep the advantages Billfront can't easily copy. Gives a short comparison only where it matters.

Output

MEMORANDUM

TO: Dan Whitlock, CEO FROM: PM for Growth DATE: October 14, 2023 SUBJECT: Competitive Analysis: Billfront & Win/Loss Findings

---

Executive Summary

Billfront is not killing us. Across the last two quarters (130 evaluated deals), our win rate stands at 65% (84 wins).

Of the 46 deals lost, 54% (25 deals) were lost to inertia and the status quo (“No decision”), not a competitor. Billfront won 17 deals (37% of losses), but 65% of those losses were concentrated in a single niche: cross-border agencies needing live multi-currency rates.

Matching Billfront feature-for-feature by Q2 would misallocate our roadmap to chase a customer segment that accounts for just 7.4% of our revenue, while ignoring the friction costing us half of our lost pipeline in our core market.

---

1. Who We Really Lose To

Our win/loss data over the last two quarters paints a very clear picture of why prospective customers fail to convert:

``` Loss Reasons Across All Segments (46 Lost Deals) ┌───────────────────────────────────────────────┬───────┬───────┐ │ Competitor / Outcome │ Deals │ Share │ ├───────────────────────────────────────────────┼───────┼───────┤ │ No Decision: "Didn't get round to switching" │ 16 │ 35% │ │ Billfront: Multi-currency FX gap │ 11 │ 24% │ │ No Decision: Stayed on Spreadsheets / Word │ 9 │ 20% │ │ Billfront: Price │ 6 │ 13% │ │ Xero: Accountant preference │ 4 │ 9% │ └───────────────────────────────────────────────┴───────┴───────┘ ```

  • #1 Competitor: Status Quo & Inertia (25 deals / 54% of losses). Small businesses abandon onboarding because switching is too painful (14 deals), and freelancers default back to Word/Excel templates (9 deals).
  • #2 Competitor: Billfront (17 deals / 37% of losses). 11 of these were multi-currency agencies; only 6 were core domestic freelancers or small businesses citing price.
  • #3 Competitor: Accounting Ecosystem Lock-in (4 deals / 9% of losses). Small businesses whose external accountants mandate Xero.

---

2. Where Billfront Is (and Isn't) a Threat

To evaluate Billfront’s threat level, we must cross-reference our losses against where our revenue actually comes from:

Customer SegmentPaying CustomersARPUMonthly Revenue% of Total MRR
:---:---:---:---:---
Freelancer5,800$11$63,80042.7%
Small Business3,100$24$74,40049.9%
Agency (Multi-Currency)240$46$11,0407.4%
Total9,140—$149,240100%

#### Where Billfront is a real threat: * Multi-Currency Agencies: Billfront launched multi-currency invoicing with live FX in March and is winning on that capability. We lost 11 agency deals specifically on this feature. If an agency invoices international clients in varying currencies, we currently do not compete.

#### Where Billfront is NOT a threat: * Freelancers and Domestic SMBs: These two groups generate 92.6% of our revenue ($138k MRR). Out of 110 pipeline trials in these segments, Billfront took only 6 deals (5.5%). * Billfront’s starting tier is $12/month (vs. our $9/month). The 6 price losses suggest confusion around feature gating between our tiers rather than Billfront undercutting our baseline price.

---

3. Where Billfront Is Heading

Billfront’s public positioning and hiring roadmap reveal an explicit upmarket strategy: * Positioning: Rebranded to "Invoicing for global teams", with agency-only case studies. * Recent Releases: Client portal (June), multi-currency (March). * Hiring: Actively recruiting 4 engineers for "global payments" and 2 for "agency workflows".

Billfront is vacating the simple domestic SMB and freelancer market to become specialized back-office software for distributed, cross-border agencies. Chasing them feature-for-feature means chasing them into an enterprise agency tier.

---

4. Strategic Recommendation: What We Should Do Instead

Matching Billfront’s entire product by Q2 would consume all engineering resources on agency workflows (portals, complex multi-currency ledgering, global payments) for our smallest segment, while leaving our 93% revenue engine vulnerable to churn and onboarding friction.

Instead, I propose a focused, dual-track plan for Q1–Q2:

#### Pillar 1: Attack the 54% "No Decision" Leak (Growth Priority) Reducing activation friction will yield 3x the revenue impact of chasing agency features: 1. Frictionless Migration Tooling: Build 1-click CSV/spreadsheet import for customer lists and open invoices to eliminate the "didn't get round to switching" barrier for SMBs. 2. Template-to-App Onboarding: Create lightweight web invoice generators that let spreadsheet users experience Tallybook’s value before forcing account creation. 3. Accountant Collaboration View: Introduce a basic accountant export/read-only seat to stop leakage to Xero.

#### Pillar 2: Selective Multi-Currency Response (Monetization Priority) We should not build custom "agency workflows," but we should neutralize the specific product gap causing deal losses: 1. Targeted Multi-Currency & Live FX: Integrate automated FX exchange rates for cross-border invoicing by Q2. 2. Package as a Premium Tier / Add-on: Billfront charges $29/mo (Pro) and $59/mo (Team) for this. We can package multi-currency into a dedicated $49/mo "International Tier" or a paid add-on, immediately lifting agency ARPU without bloating the product for domestic users.

#### Pillar 3: Audit Pricing Tiers Investigate the 6 lost deals to Billfront on price. Ensure our $9 entry plan is clearly differentiated and does not wall off basic capabilities that drive price-sensitive users away.

---

Next Steps

I recommend holding off on an across-the-board feature-parity initiative. I will deliver a detailed spec and ROI projection by Friday for (1) Migration/Switching Flow Optimization and (2) Multi-Currency Invoicing as a Premium Add-on for Q1 delivery.

Output

To: Dan Whitlock Subject: Q2 competitive plan—beat the reasons we lose, not Billfront’s feature list

Dan—

Billfront is a real threat in multi-currency agencies, but the deal data does not support “Billfront is killing us” across our business. I recommend a Q2 plan focused on switching friction in our core market, with a gated investment in multi-currency—not blanket feature parity.

1. Who we actually lose to

Across 130 trials with recorded outcomes over the last two quarters, we won 84 and lost 46.

DestinationLost dealsShare of lossesRecorded reason
------:---:---
No decision2554%16 never switched; 9 stayed with spreadsheets/Word
Billfront1737%11 multi-currency/live FX; 6 price
Xero invoicing49%Accountant uses another system

Our largest competitor is inertia. More deals stall or retain manual workflows than go to Billfront.

The segment split matters:

  • Freelancers and small businesses: 110 opportunities, 77 wins, and only six losses to Billfront—all attributed to price.
  • Multi-currency agencies: 20 opportunities, seven wins, 11 losses to Billfront, and two no-decisions. Billfront captures 55% of these opportunities and 85% of their losses.

These are counts from recorded trial outcomes—not market share, churn, or revenue-weighted losses. We lack deal values and quarter-by-quarter breakdowns, so cannot conclude that competitive losses are accelerating.

2. Where Billfront threatens us—and where it doesn’t

Our installed base remains overwhelmingly freelancers and small businesses: 97% of paying customers and 93% of monthly revenue, using September customer counts and ARPU. Agencies contribute approximately $11,040 of $149,240 monthly revenue.

Billfront is therefore a concentrated segment threat, not yet a demonstrated broad-based threat to our core. However, agencies represent 15% of this opportunity sample versus 3% of current customers. Ignoring them could constrain an emerging growth segment.

The defensible comparison from the supplied evidence is:

DimensionBillfrontTallybook / implication
Subscription pricing$12 Starter; $29 Pro; $59 Team$9–$39 plans. Billfront is not universally cheaper; investigate the actual packages compared in six price losses.
Multi-currency and live FXIncluded in Pro; multi-currency launched in MarchEleven losses establish an unmet customer requirement. This is the strongest case for targeted parity.
Client portalLaunched in JuneTallybook capability is unspecified. No recorded loss cites it; validate demand before prioritizing.
Team/agency capabilitiesTeam tier; agency-focused hiringDetailed functionality is unknown. Neither the plan name nor hiring proves specific feature advantages.
Positioning“Invoicing for global teams”; three agency and one consultancy case studiesTallybook serves freelancers and small businesses. Their positioning overlaps most strongly with our agency segment.

A complete feature-by-feature audit requires product access and our own capability inventory. We should do a bounded audit, but not turn every discovered difference into a roadmap commitment.

3. Where Billfront is heading

The evidence points toward cross-border payments and agency workflows: multi-currency is already shipped, four engineering roles target global payments, and two target agency workflows. The portal could support deeper agency-client collaboration.

That suggests a specialist competitor becoming stronger in international service businesses—not necessarily a competitor optimizing for solo freelancers. Hiring indicates direction, not a confirmed launch schedule. Matching today’s list could leave us following their next list while neglecting our larger conversion problem.

4. What we should do by Q2

First: make switching easier for our core customers. Interview recent no-decision prospects, then test guided setup, spreadsheet/client imports, reusable invoice templates, and assisted migration where the workflow audit shows gaps. Sell the outcome—getting the first invoice sent and paid with less effort—not feature volume. Measure trial-to-paid conversion, time to first invoice, first payment, and no-decision losses against a baseline or control.

Second: gate a focused multi-currency investment. Validate requirements with lost agencies and our seven agency wins: supported currencies, live-rate handling, settlement needs, and willingness to pay. Estimate build, provider, compliance, and support costs. Commit to a scoped Q2 release only if expected incremental contribution and retention justify it versus core activation work. Do not bundle a portal or full Team suite into that decision.

Third: diagnose price before cutting it. Review the six price losses for required features, chosen Billfront tier, discounts, and perceived value. Test clearer packaging or targeted offers rather than an across-the-board reduction. Reconcile agency ARPU of $46 with our stated $39 plan ceiling before modeling returns.

Fourth: reduce accountant-driven exclusions. Investigate the four Xero losses and test whether accountant-friendly exports or interoperability can preserve Tallybook as the invoicing layer.

Decision requested: replace “match everything by Q2” with a measured conversion program and a gated multi-currency bet. Keep a monthly competitor review, but fund work according to customer demand and incremental economics—not checklist completeness.

Cost is each output’s tokens at the model’s list price, shown relative to the cheapest setup. Runs done in an app have no usage meter, so theirs are estimated from the same setup’s measured runs. How we compare cost

About the task

The PM job

Deciding how to respond to competitors.

Why it matters

Feature grids hide the real competition, which is often the customer's current workaround, and the response that feels urgent is usually to copy everything.

What good looks like

  • Includes the status quo and non-obvious alternatives
  • Finds where losses really go, by segment
  • Separates advantages a rival can copy from ones it can't
  • Reads where competitors are heading

Deliberately not measured

  • Market sizing
Capability tested
