Fieldline Pay: the case against the plan as written

Sep 25, 2026 · @Martin Slaney · Pre-read for exec offsite

Bottom line

The $24M figure applies a card-only margin to invoice value that is mostly not paid by card. Re-estimated from our own data, Fieldline Pay is a $2–7M business at month 24, central case about $4M. That is worth building, but not with three squads for three quarters, and not by pausing the rewrite that cost us $1.9M ARR last year.

1. The assumption that breaks: a 0.7% blended take

The 0.7% is not a blended rate. It is our net margin on card payments (2.9% charged, \~2.2% cost). The model applies it to all $4.83B.

• Card is 19% of invoice value today. ACH is 44%, check 31%, cash 6%.
• ACH nets a flat $1.60 per payment. On a $3,800 commercial invoice that is 0.04%; on a $410 residential invoice, 0.39%.
• Checks and cash earn nothing.
• Commercial is 58% of value, and its card share is 5%. With pay-by-link on every invoice, the pilot moved it to 6%. Sales and 11 of 14 commercial-heavy interviewees say clients require ACH or check.

Worked through at pilot-level card adoption (assuming half of non-card value moves to ACH):

At today's payment mix, with no card uplift, blended take is about 0.15%.³

The $24M needs 0.71% across 70% of customers: every processed dollar on card. Even 100% adoption of all $4.83B would need 0.50%, above what the residential-skewed pilot achieved (\~0.38%).

Two things compound it:

• Adoption by customers is not adoption by value. The top 115 customers hold 48% of value; 71 are locked into processor contracts, mostly to 2028. Pro rata, that is \~$1.43B (30% of value) out of reach in the window. The pilot's 61% came from an invited, 64%-residential cohort.
• Tradesly is not a comparable. It is \~80% residential; we are 42%. Its 22% shows residential payments work, which our pilot confirms. It says nothing about commercial.

2. Re-estimate: $2–7M at month 24

Addressable value = $4.83B less about $1.43B locked = about $3.4B. Revenue = addressable value × value-weighted adoption × blended take.

Cross-check from the pilot: $5,630 per customer a year on a 64%-residential cohort. Re-weighted to our mix (0.27% ÷ 0.38%) that is \~$4,000. Across 1,000–1,560 adopters (45–70% of the 2,229 unlocked customers), it gives $4.0–6.2M, consistent with the central-to-high cases.

Central case is \~10% of current ARR, not the 35% of revenue told to the board. Against it: three squads for three quarters, and the rewrite delayed in a segment that lost $1.9M ARR last year. At the central case, year-two payments revenue roughly covers two years of that churn if it continues.

3. What would prove this wrong, and the cheapest test

I am wrong if commercial invoice value can be moved onto rails we earn on. The threshold: a commercially representative cohort showing blended net take of 0.5% or more through Pay. Below 0.3%, the $24M is off the table.²

Six-week test, configuration only, no new build:

1. Enable Pay for 30 customers with at least 60% commercial invoice value, none from the pilot.
2. Attach pay-links to open invoices sent in the last 60 days, not just new ones. Commercial invoices take 52 days to pay; new invoices alone won't settle inside six weeks.
3. Split the cohort on ACH price: half at the current flat $2, half at 0.5% capped at $25. Flat pricing is why commercial ACH earns $1.60 on a $3,800 invoice instead of $19.
4. Make payment-method capture mandatory for the cohort, so we stop relying on the 30% who record it.
5. Measure value-weighted method mix and net take by segment, plus opt-outs and payer complaints.

Alongside it, at no cost: account managers ask the 44 unlocked top-115 accounts whether they would move processors in 2027. More than ten yeses changes the adoption maths.

4. What to do instead

Shrink the bet, point it where the evidence is, and gate the rest.

• Keep the scheduling rewrite. It protects known ARR. Payments is unproven in the segment that holds most of the value.
• One squad on Pay for residential work now. The pilot shows it works there (71% card share). Ship pay-by-link, default on.
• Reprice ACH from flat $2 to a capped percentage, subject to the test. It is the largest lever on commercial take and needs no new build.
• Go after the real problem. 17 of 22 customers named getting paid on commercial jobs as their biggest cash problem; invoices take 52 days; 9 would pay to be paid faster. An early-payout product (for example, 1.5% to get paid in two days) earns $57 on a $3,800 invoice against $1.60 on ACH.¹ It earns on the 58% of value that card never will. It needs a capital partner; scope it in the same six weeks with a priced offer to 10 commercial customers.
• Gate at week six. If commercial take clears 0.5% or the early-payout offer converts, add squads then.
• Reset the board number now. We raise in about 14 months, when Pay will show perhaps a $2–3M run-rate. Walking the board from $24M to a range today is cheaper than explaining the gap in a data room.

Executive Summary

Committing three squads for three quarters to Fieldline Pay to capture $24M in new revenue within two years is a high-risk bet that relies on a structural distortion in our financial model.

The plan’s core vulnerability is not execution; it is a misallocation of our customer base's economic reality. By using the mean invoice value ($2.1M) rather than the median ($640k), the model assumes our average customer mirrors our largest commercial accounts¹, while simultaneously ignoring entrenched enterprise contracts and commercial payment norms.

Executing this plan requires pausing the scheduling rewrite, which risks $1.9M in annual churn from our largest, most valuable accounts. Below is the evidence-based challenge, a revised revenue range, an inexpensive six-week test, and a recommended alternative path.

1. The Dependent Assumption and Why the Evidence Fails It

> The Plan's Single Dependent Assumption: That we can achieve a $23.7M–$24M revenue run-rate by month 24 by applying a blended 0.7% net take rate across a homogenous $2.1M annual invoice volume per adopted customer.

The evidence flatly refutes this assumption in three ways:

• The Mean vs. Median Distortion: The CEO's model relies on a mean invoice value of $2.1M. However, the median customer invoices just $640k. Our distribution is heavily skewed: the top 5% of customers (115 accounts) drive 48% ($2.32B) of our total invoiced value.
• Enterprise Lock-in: Of those 115 largest customers, 71 are locked into multi-year contracts with existing payment processors running through 2028. As the Head of Sales noted, none will migrate early.
• The Commercial Wall: Commercial jobs comprise 58% of our invoiced value ($2.80B). The average commercial invoice is $3,800 and is paid on net-45/net-60 terms (averaging 52 days). Property managers and facility contractors will not pay a 2.9% card surcharge on a $3,800 invoice. They pay via ACH ($2.00 flat fee, netting us $1.60) or check ($0 revenue), exactly as they always have.

Applying a 0.7% card take-rate model to commercial volume is fundamentally flawed because commercial clients do not use cards (card share is only 5% for commercial, vs. 38% for residential).

2. Re-Estimated Revenue Range (Working Included)

To model realistic revenue, we must segment our base by customer type, recognizing that residential and commercial segments have radically different payment behaviors and take rates.

#### Step-by-Step Working: 1. Customer Base: 2,300 total customers. 2. Adoption Rate: Pilot adoption was 61% (close to the 70% target). Let's model a realistic 60% adoption rate by month 24 = $1,380$ adopting customers. 3. Segmentation Split: Based on overall volume, 42% of value is residential ($2.03B) and 58% is commercial ($2.80B). Total invoiced value = $4.83B. * Total Residential Invoiced: $2.03B ($\approx$ $882k$ per customer across 2,300) * Total Commercial Invoiced: $2.80B ($\approx$ $1.22M$ per customer across 2,300) 4. Take Rates & Behavior: * Residential: 71% card adoption via pay-by-link. Net take rate on card is 0.7%. ACH/Check take rate is near zero (flat $1.60 net on ACH, negligible volume). Effective blended take rate on residential volume $\approx$ $0.7\% \times 71\% \approx \mathbf{0.50\%}$. * Commercial: 6% card adoption, 94% ACH/Check/Terms. Card take rate is 0.7%; ACH nets a flat $1.60 per transaction (on a $3,800 invoice, $1.60 is a 0.04% effective take rate). Effective blended take rate on commercial volume $\approx$ $\mathbf{0.08\%}$.

#### The Realistic Range (Month 24 Run-Rate): * Bear Case ($3.2M ARR): Commercial customers reject card fees entirely, sticking strictly to ACH/checks; residential adoption stalls at 45% due to surcharge pushback. * Base Case ($6.1M ARR): 60% overall adoption. Residential volume yields a 0.50% blended take ($2.03B $\times$ 60% adoption $\times$ 0.50% = $6.09M). Commercial yields minimal flat-fee ACH revenue. * Bull Case ($9.8M ARR):³ 70% adoption matches the CEO's target, and we successfully introduce a B2B "accelerated payout" fee (drawing on the 9 customers out of 22 who said they would pay a fee to solve their $200k payroll float).

> Result: The realistic revenue run-rate at Month 24 is $3.2M to $9.8M, falling drastically short of the $24M target.

3. Falsification Criteria and a Six-Week Test

#### What would prove us wrong? If a randomized cohort of commercial-heavy customers willingly adopts card payments at >20% volume despite a 2.9% surcharge, or if property managers accept automated card-on-file billing for invoices over $3,000, our commercial pessimism is unfounded.

#### The Six-Week Test ($15k budget, 1 squad for 6 weeks): * The Experiment: Launch a targeted "Fast-Pay Commercial Portal" pilot with 30 mid-market commercial customers currently handling invoices between $2,000 and $5,000. * The Mechanics: Offer them an explicit choice: continue standard net-45 terms via free ACH, or use a discounted commercial card rate (e.g., split-surcharge or 1.9% + $0.30 via a specialized B2B interchange tier)² to get paid in 48 hours. * Success Metric: Do at least 25% of their commercial payors opt-in to the digital card rail over 6 weeks? If not, the commercial card thesis is dead.

4. What We Should Do Instead

Pausing the scheduling rewrite to chase an illusory $24M payments figure is a strategic trap. The scheduling rewrite is our defensive moat: losing it costs us $1.9M in high-value churn annually from customers with >50 technicians.

#### Recommended Pivot: 1. Protect Core Engineering: Keep the scheduling rewrite on track. Do not cannibalize the core product teams for a pivot that math shows yields ~$6M, not $24M. Allocate one dedicated squad (not three) to productize payments iteratively. 2. Pivot the Value Proposition: Stop trying to monetize residential card transactions where competition (Tradesly, Stripe) is fierce. Instead, solve the actual pain point identified in customer interviews: commercial cash flow float. 3. Build B2B Working Capital Solutions: Build features that help trades businesses bridge the net-45 gap (e.g., instant payout/invoice factoring models embedded in Fieldline Pay) rather than relying purely on interchange take-rates.

Given that our next Series C raise is in 14 months, how comfortable is the board with a realistic payments ARR of $6M built on workflow efficiency, versus an aggressive $24M gamble that risks our core enterprise retention?
