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.

To: Dan Whitlock From: PM, Growth Re: Billfront competitive analysis

Bottom line: Billfront is beating us in one segment: multi-currency agencies. Elsewhere we mostly lose to inertia, not to them. Matching Billfront feature by feature would spend Q2 on the wrong problem. I recommend a scoped multi-currency build for agencies plus a push to convert stalled trials.

Who we actually lose to

Over the last two quarters we won 84 of 130 trials (65%) and lost 46:

Loss reasonLossesShare
No decision: "didn't get round to switching"1635%
No decision: stayed on spreadsheets / Word920%
Billfront: multi-currency with live rates1124%
Billfront: price613%
Accountant uses Xero49%

Fifty-four percent of our losses go to doing nothing. Billfront accounts for 37%.

Segment matters more than count. Agencies win only 7 of 20 trials (35%), against 77% for freelancers and 63% for small businesses. Eleven of our 13 agency losses went to Billfront. Agencies are 240 customers paying $46 a month, so weighting lost deals by segment revenue, Billfront-attributed losses come to roughly $610 a month, and about 83% of that is multi-currency agencies.

Where Billfront is a real threat

  • Multi-currency agencies. Their $29 Pro tier sells live FX rates, and we don't match that for this buyer. This is the one feature gap costing us repeatedly.
  • Their direction. The homepage says "Invoicing for global teams," three of their four case studies are agencies, and they launched multi-currency in March. Their job posts show four engineers on global payments and two on agency workflows. They're moving toward the segment where we're weakest.

Where it isn't

  • Freelancers and small businesses. Only 6 of our 46 losses went to Billfront on price, and none cite a missing feature. Most losses in these segments are status quo.
  • Price. Billfront's Starter is $12 against our $9 entry, so their cheapest plan costs more than ours. The price losses are probably at our mid tier against their Pro or Starter. I'd need the deal notes to confirm, but six deals don't justify a broad price cut.
  • Client portal. Billfront launched it in June, and no lost deal mentions it.

What to do instead of, or as well as, matching

  1. Scope live-FX multi-currency invoicing for agencies (Q2 target). Build what agencies actually need, not Billfront's full feature list. Integrating an FX rate feed will likely be faster than building rate infrastructure. Target: lift agency win rate from 35% to 50% or more.
  2. Work the 25 no-decision losses. "Didn't get round to switching" and "stayed on spreadsheets" point to trial follow-up and migration problems. Test a spreadsheet and Word-template importer, a personal check-in from sales on high-value trials around day 7, and a time-limited switch offer. Run these in two-week cycles and measure conversion.
  3. Address the accountant problem (4 losses). Let accountants view and collaborate on invoices, and check our Xero sync coverage.
  4. Don't chase parity. Skip the client portal and other Billfront features unless losses start citing them. Track loss reasons monthly so future roadmap decisions rest on data.

Caveats

  • 130 trials is a small sample, and loss reasons are rep-recorded. The agency figures rest on just 20 deals.
  • Agency ARPU of $46 is above our $39 top plan, so these customers are probably on add-ons or custom pricing. I'll confirm this before we size the multi-currency opportunity.
  • Billfront's pricing and job posts are public signals, not a confirmed roadmap.

Ask: Approve a two-week scoping sprint for agency multi-currency and a six-week trial-conversion test. I'll bring back scope, cost, and expected impact by the end of the sprint.

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.

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.

---

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

Claims the judge couldn’t find in the brief

  • Out of 130 trial outcomes, 74 trials were won (57%) and 56 were lost (43%).
  • No Decision / Inertia accounts for 38 lost deals (68% of losses): 16 stayed on spreadsheets, 22 didn't get round to switching.
  • Billfront took 14 losses (25% of losses): 4 on price, 10 on multi-currency.
  • Tallybook's core invoicing has robust, clean templates.
  • Tallybook's multi-currency support is basic manual entry / limited support.
  • Tallybook's client portal is a basic payment link view.
  • Tallybook has a single-user focus and standard payment gateways.
  • Building a multi-currency engine requires heavy compliance, banking integrations, and engineering overhead.
  • Billfront is deliberately abandoning the low-end freelancer market.
  • Billfront's $12 tier undercuts our SMB/Freelancer fence for price-sensitive buyers.

Check by check

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 correctlyRightMixedWrong
Haiku 5.5 · API

All facts and figures used to describe the current situation are drawn directly from the supplied context or arithmetic from that context, with no inventions.

Gemini 3.8 Flash · API

All factual claims about the current situation are taken correctly from the supplied context or derived by accurate arithmetic; the one unsupported claim is a forecast, not a current-situation fact.

Gemini 3.5 Flash-Lite · Gemini

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

Addresses the actual decisionRightMixedMixed
Haiku 5.5 · API

The output unambiguously commits to a clear call (do not match Billfront feature-by-feature; instead build multi-currency for agencies and address no-decision losses) framed for the CEO, with an ask for approval.

Gemini 3.8 Flash · API

The output commits to a clear recommendation (don't match everything, do Pillars 1-3) but does not state what result or condition would change that call, as required.

Gemini 3.5 Flash-Lite · Gemini

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

Identifies material uncertaintyRightWrongWrong
Haiku 5.5 · API

The output names small sample size, rep-recorded reasons, uncertain ARPU composition, and unconfirmed Billfront roadmap, and says it will confirm ARPU before sizing, thus identifying material uncertainties and how they will be resolved.

Gemini 3.8 Flash · API

The output does not name specific unknowns that could change the decision, nor say how they would be resolved or what would change the call.

Gemini 3.5 Flash-Lite · Gemini

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

Avoids unsupported claimsRightWrongWrong
Haiku 5.5 · API

The analysis presents hypotheses (e.g., trial follow-up and migration problems) as interpretations, not established facts, and caveats are provided for weaker signals.

Gemini 3.8 Flash · API

The claim that 'Billfront is vacating the simple domestic SMB and freelancer market' is presented as an established fact, but the evidence only shows they are targeting agencies, not that they are leaving other markets.

Gemini 3.5 Flash-Lite · Gemini

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

Produces the required deliverableRightRightMixed
Haiku 5.5 · API

The memo is in the requested form, addressed to Dan, within the word limit, and contains a complete set of recommendations that the CEO could act on with minimal edits.

Gemini 3.8 Flash · API

The memo is complete, within 900 words, addressed to Dan, and provides a usable competitive analysis with a clear recommendation.

Gemini 3.5 Flash-Lite · Gemini

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

Finds the real competitorRightRightMixed
Haiku 5.5 · API

The analysis counts losses by destination (25 no decision, 17 Billfront) and names no decision as the biggest competitor with the numbers.

Gemini 3.8 Flash · API

The analysis counts losses by destination, shows 25 no-decision losses vs 17 to Billfront, and names no decision as the biggest competitor.

Gemini 3.5 Flash-Lite · Gemini

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

Pins down where Billfront winsRightRightMixed
Haiku 5.5 · API

It shows Billfront's wins are concentrated in multi-currency agencies (11 of 17), and sizes that segment's revenue ($11k MRR) against the larger freelancer and small business segments.

Gemini 3.8 Flash · API

It shows Billfront's wins are concentrated in multi-currency agencies (11 of 17) and sizes the agency segment at 7.4% of MRR against freelancer and small business.

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.

Gets the base of every number rightRightRightWrong
Haiku 5.5 · API

All percentages and rates (e.g., 84/130 = 65%, 25/46 = 54%, win rates, revenue calculation) are computed correctly from the supplied data, with bases clear.

Gemini 3.8 Flash · API

All derived percentages and rates use the correct denominators (130 deals, 46 losses, 110 freelancer+small business trials) and check out against the data.

Gemini 3.5 Flash-Lite · Gemini

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

All got wrong 1

Separates what a rival can copyWrongWrongWrong
Haiku 5.5 · API

The analysis does not separate advantages a well-funded competitor could copy (features, price) from durable ones (switching costs, networks, relationships), nor anchor the response in the latter.

Gemini 3.8 Flash · API

The output does not explicitly name which advantages are copyable and which are durable, nor anchor the response in the latter, as required.

Gemini 3.5 Flash-Lite · Gemini

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

All got right 2

Respects explicit constraintsRightRightRight
Haiku 5.5 · API

The output is a competitive analysis under 900 words, addresses the five requested areas, and does not propose a full feature-by-feature matching plan, respecting the explicit prohibitions.

Gemini 3.8 Flash · API

The output is a competitive analysis memo under 900 words, addressed to the CEO, and does not propose a full feature-by-feature matching plan, respecting the brief's request to say what to do instead.

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.

Competes with what customers really chooseRightRightRight
Haiku 5.5 · API

The status quo (spreadsheets, not switching) is treated as a real competitor, and the analysis incorporates Billfront's direction of travel (global payments, agency workflows) to inform the recommendation.

Gemini 3.8 Flash · API

The analysis treats spreadsheets and inertia as a competitor, and draws a direction-of-travel insight (Billfront moving upmarket) that affects the recommendation.

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.

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
