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.

    April DunfordLenny’s Podcast

  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.

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.

MEMORANDUM

TO: Dan Whitlock, CEO FROM: Growth PM DATE: October 24, 2023 SUBJECT: Competitive Analysis: Tallybook vs. Billfront & Q2 Growth Strategy

---

Dan,

You noted that "Billfront is killing us" and asked for a feature match by Q2. I’ve dug into our last two quarters of deal data (trials T-900 through T-1029) and analyzed Billfront’s public footprint.

The data tells a surprising story: Billfront is not killing us broadly. In fact, we are winning the vast majority of our trials. However, Billfront is systematically poaching a very specific, high-value segment.

Below is our competitive reality check, a feature comparison, and a smarter Q2 plan than simply copying their roadmap.

---

1. Who We Really Lose To (The Data)

Out of 130 trial outcomes analyzed from the last two quarters, 74 trials were won (57%) and 56 were lost (43%).

When we lose, where do those deals actually go? * No Decision / Inertia (38 lost / 68% of losses): * Stayed on spreadsheets / Word templates: 16 losses. * Didn't get round to switching: 22 losses. * Takeaway: Our biggest enemy isn't a competitor; it's friction and customer apathy. * Xero (4 losses / 7% of losses): Small businesses whose accountants forced them onto an enterprise ledger. * Billfront (14 losses / 25% of losses): * Price: 4 freelancer losses (lost to their $12 entry tier vs our $9–$11 range). * Needs invoicing in several currencies with live rates: 10 agency losses.

The Verdict: Billfront is only a threat in the Multi-Currency Agency segment. They are positioning themselves as a vertical tool for global agencies, while we are trying to be a generalist tool.

Global Payments / TeamsSingle-user focus, standard gatewaysLocalization, team workflows, agency toolsFuture Threat: Their current hiring (4 engineers for global payments, 2 for agency workflows) proves they are doubling down here.

---

3. Where Billfront is Heading

Based on their job postings and recent launches (client portal in June, multi-currency in March), Billfront is moving upmarket into localized, multi-entity agency operations. They are deliberately abandoning the low-end freelancer market to capture high-value agencies paying $59+/month.

If we spend Q2 blindly matching their features (like building a complex client portal or team permissions), we will burn engineering cycles copying a product that is deliberately scaling away from our bread-and-butter.

---

4. Strategic Recommendation: What We Should Do Instead of Matching

Our revenue is anchored by 5,800 Freelancers ($11 ARPU) and 3,100 Small Businesses ($24 ARPU). Our 240 Agencies ($46 ARPU) are nice, but they represent a fraction of our base.

Instead of playing catch-up to Billfront in a market we aren't optimized to win, we should execute a three-part growth plan for Q2:

#### A. Surrender the Multi-Currency Agency Segment (Deliberately) Stop trying to win agencies that demand live FX rates. Building a multi-currency engine requires heavy compliance, banking integrations, and engineering overhead to chase 10 lost deals a quarter. Let Billfront have them.

#### B. Fix the Real Leaks: Inertia and Onboarding (High ROI) Since 68% of our losses are to "No Decision," our biggest growth lever is reducing time-to-first-invoice for people stuck on spreadsheets. * Action: Build a 1-click CSV importer for past invoices and client lists in Q2. If we can convert half of the "spreadsheet/word template" drop-offs, we instantly capture 8+ new accounts a quarter without touching our pricing.

#### C. Protect the SMB Flank with Smart Packaging Billfront is picking off price-sensitive freelancers with their $12 tier. * Action: Introduce a streamlined "Solo" tier at $10/mo with zero friction, and double down on Tallybook's core differentiator: speed and simplicity for domestic small businesses and freelancers who don't care about global FX rates, they just want to get paid fast.

Summary: Billfront isn't killing us—they are just taking the multi-currency headaches off our hands. Let’s focus Q2 engineering power on wiping out spreadsheet inertia rather than chasing Billfront's agency ghost.

Best, Growth PM, Tallybook

Output

Competitive analysis: Billfront is a targeted threat—not our biggest source of losses

To: Dan Whitlock From: Growth PM

Recommendation: Do not commit to matching every Billfront feature by Q2. Commit to reducing switching friction in our core market, testing price objections, and validating a focused multi-currency response. Maintain a competitive feature inventory, but let customer evidence—not competitor launches—drive delivery.

1. Who we actually lose to

Across the 130 trial opportunities in the last two quarters, we won 84 and lost 46:

Loss destinationDealsShare of lossesRecorded reason
------:---:---
No decision2554%16 never switched; 9 stayed with spreadsheets/Word
Billfront1737%11 needed multi-currency/live rates; 6 cited price
Xero invoicing49%Accountant preference

Our largest competitor is inertia. More opportunities stayed with their existing process than chose Billfront. Feature parity does not directly address those losses.

Billfront’s wins are concentrated: 11 of its 17 wins came from multi-currency agencies. Among the 110 freelancer and small-business opportunities, only six went to Billfront—all citing price.

These are trial-opportunity outcomes, not evidence of customer churn or overall market share. We also lack deal values, so counts alone cannot establish the revenue impact.

2. Where Billfront is—and is not—a real threat

Real threat: international agencies. Of 20 agency opportunities, we won seven, lost 11 to Billfront over multi-currency/live rates, and lost two to no decision. That is a specific, repeated capability gap, not a vague brand problem.

Agencies are a small but valuable segment: 240 paying customers generate approximately $11,040 monthly revenue, or 7.4% of the total, at the highest segment average of $46 per month. Protecting this segment merits investigation; pursuing it aggressively requires a deliberate market choice.

Limited demonstrated threat: our core market. Freelancers and small businesses represent 97.4% of paying customers and 92.6% of monthly revenue. Their recorded Billfront losses concern price, not missing portals or team workflows.

That does not mean price is objectively lower: Tallybook starts at $9 versus Billfront’s $12. We need to understand required tiers, perceived value, discounts, and payment costs before changing prices.

Separate threat: accountant-led selection. Four small businesses chose Xero because their accountant used it. Matching Billfront does nothing to resolve that workflow preference.

3. Feature comparison: what the evidence supports

A full parity assessment is not possible from these files: we lack Tallybook’s feature inventory and detailed Billfront documentation.

AreaBillfront evidenceTallybook evidence / implication
InvoicingPublic positioning and launches confirm offeringCore Tallybook offering; workflow-level parity unverified
Payments“Global payments” hiringCore Tallybook offering; global capabilities unverified
Pricing$12 Starter; $29 Pro; $59 Team$9–$39 plans; six price losses require tier-level investigation
Multi-currency + live FXIncluded in $29 Pro; launched MarchEleven losses establish an unmet requirement; exact existing coverage needs audit
Client portalLaunched JuneAvailability unknown; no recorded loss cites it
Team/agency workflowsTeam plan; agency-workflow hiringDetailed features unknown; no evidenced parity requirement yet

We should complete this inventory through product testing and documentation—not turn unknowns into assumed deficiencies.

4. Where Billfront appears to be heading

“Invoicing for global teams,” three agency case studies, one consultancy case study, and hiring for global payments and agency workflows point toward cross-border agency operations, rather than primarily low-cost freelancer invoicing.

The multi-currency launch and portal fit that direction. Hiring suggests possible investment in global payment capabilities and deeper agency workflows, but does not confirm particular upcoming features.

Following that trajectory wholesale would move us toward a different customer and potentially greater operational complexity.

5. What we should deliver by Q2

First: establish the facts. Product and Growth should audit both products, interview the 17 Billfront losses and a sample of no-decision opportunities, and identify the exact currency, payment, migration, and price requirements. Validate engineering scope before promising parity.

Prioritize core conversion. Test guided setup, invoice/customer import, template migration, and assisted switching. Measure first-invoice activation, time to first invoice, and trial-to-paid conversion against a control—not just onboarding completion.

Address price without a blanket cut. Test clearer tier/value messaging and targeted offers for price-sensitive prospects. Judge success on paid conversion, retained revenue, and margin.

Gate a focused FX investment. Scope multi-currency invoicing with live rates—not the entire global-payments stack. Proceed only if recoverable agency revenue, customer demand, and delivery cost justify it. Use agency design partners and explicit pilot adoption and retention criteria.

Investigate accountant compatibility. Determine whether exports, accountant access, or integrations would resolve the Xero losses before building.

Q2 commitment: validated competitive coverage, measured conversion experiments, and an evidence-based FX build decision—not indiscriminate feature parity.

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.

Where the outputs differ comes first. Open a check to read the judge’s reasons. “Mixed” means the two graders disagreed.

Where they differ 8

Uses the supplied evidence correctlyWrongRightRight
Gemini 3.5 Flash-Lite · Gemini

Key numbers (wins, losses, breakdown by reason) are incorrect, and many feature claims about Tallybook are invented.

GPT-6.1 Sol · API

All factual claims are directly from the supplied files or derived by correct arithmetic.

GPT-6 Astra · ChatGPT

All facts and figures are correctly taken from the supplied data, with no invented information about the current situation.

Addresses the actual decisionMixedRightRight
Gemini 3.5 Flash-Lite · Gemini

Does not state what result or condition would change the recommendation.

GPT-6.1 Sol · API

Commits early to not matching everything, gives a clear alternative, and states conditions (recoverable revenue, demand, cost) that would change the call.

GPT-6 Astra · ChatGPT

Commits clearly to not matching everything, instead recommending a switching-friction program and a gated multi-currency investment, with conditions that would change the call.

Identifies material uncertaintyWrongRightRight
Gemini 3.5 Flash-Lite · Gemini

No specific unknowns that could change the decision are named, nor how they would be resolved.

GPT-6.1 Sol · API

Names missing data (deal values, feature inventories, exact requirements) and says how to resolve them (audits, interviews, validation).

GPT-6 Astra · ChatGPT

Names missing data (deal values, quarter breakdowns) and conditions for the multi-currency investment, and says how to resolve them through interviews, tests, and validation.

Avoids unsupported claimsWrongRightRight
Gemini 3.5 Flash-Lite · Gemini

Presents interpretations (e.g., 'deliberately abandoning the low-end market') and feature details as fact without support.

GPT-6.1 Sol · API

Forecasts and interpretations are labelled as such (e.g., 'appears to be heading', 'suggests possible investment').

GPT-6 Astra · ChatGPT

Interpretations and forecasts are labelled as suggestions or conclusions from data, not presented as established fact.

Produces the required deliverableMixedRightRight
Gemini 3.5 Flash-Lite · Gemini

The analysis contains wrong numbers, so a PM cannot act on it without redoing the data work.

GPT-6.1 Sol · API

Delivers a complete, actionable competitive analysis memo for the CEO within the word limit.

GPT-6 Astra · ChatGPT

The memo is complete, within the word limit, and directly usable by the CEO with actionable recommendations.

Finds the real competitorMixedRightRight
Gemini 3.5 Flash-Lite · Gemini

Incorrectly counts no-decision losses as 38 instead of 25, and misstates the percentage.

GPT-6.1 Sol · API

Counts losses by destination, shows no decision as the largest (25 deals, 54%), and names inertia as the biggest competitor.

GPT-6 Astra · ChatGPT

Counts 25 no-decision losses versus 17 to Billfront and names inertia as the largest competitor.

Pins down where Billfront winsMixedRightRight
Gemini 3.5 Flash-Lite · Gemini

Miscounts Billfront losses and misstates the concentration; does not correctly size the segment's revenue against others with accurate numbers.

GPT-6.1 Sol · API

Shows Billfront wins concentrated in multi-currency agencies (11 of 17) and sizes the segment's revenue ($11,040/month, 7.4% of total).

GPT-6 Astra · ChatGPT

Shows Billfront's wins are concentrated in multi-currency agencies (11 of 17) and sizes the segment's revenue at $11k of $149k.

Gets the base of every number rightWrongRightRight
Gemini 3.5 Flash-Lite · Gemini

All derived percentages and counts are based on wrong win/loss totals and wrong sub-counts.

GPT-6.1 Sol · API

All percentages and counts check out against the deals file and customer data, with bases stated where needed.

GPT-6 Astra · ChatGPT

All percentages are correctly computed with clear denominators stated or implied.

All got wrong 1

Separates what a rival can copyWrongWrongWrong
Gemini 3.5 Flash-Lite · Gemini

Does not separate copyable advantages from durable ones; mentions 'speed and simplicity' but doesn't analyze its defensibility.

GPT-6.1 Sol · API

Does not explicitly separate copyable advantages (features, price) from durable ones (switching costs, relationships) or anchor the response in the latter.

GPT-6 Astra · ChatGPT

Does not explicitly separate which advantages are copyable by a well-funded competitor and which are durable, nor anchor the response in the durable ones.

All got right 2

Respects explicit constraintsRightRightRight
Gemini 3.5 Flash-Lite · Gemini

The output is a memo under 900 words, addresses the CEO, and does not propose a feature-by-feature matching plan.

GPT-6.1 Sol · API

Output is a competitive analysis under 900 words, does not provide a full feature-by-feature matching plan, and is addressed to Dan.

GPT-6 Astra · ChatGPT

The output is a competitive analysis under 900 words, addressed to the CEO, and proposes what to do instead of matching, respecting the brief's request.

Competes with what customers really chooseRightRightRight
Gemini 3.5 Flash-Lite · Gemini

Treats spreadsheets and inertia as the main competitor and draws a direction-of-travel insight from Billfront's hiring.

GPT-6.1 Sol · API

Treats spreadsheets/doing nothing as a competitor and gives a direction-of-travel insight (Billfront moving toward cross-border agency ops).

GPT-6 Astra · ChatGPT

Treats the status quo (spreadsheets, no decision) as a competitor and draws an implication from Billfront's hiring direction.

Best valueNobody beats these on both score and cost

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

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
