Challenge an idea

To: Priya Raman Subject: Fieldline Pay: challenge the $24M case before committing three squads

The strongest case against the current plan is not that embedded payments cannot work. It is that the $24M forecast treats invoice volume as if it were payment volume earning a card-like margin.

The critical unsupported assumption: 70% of customers will adopt and route enough of their invoices through Fieldline Pay to earn roughly 0.7% on that value. The 0.7% net take is specifically the card margin. ACH earns $1.60 per payment; checks and cash earn nothing. The CFO’s arithmetic is correct only if essentially every dollar from every adopting customer earns the card margin.

That is a poor fit with our mix. Commercial work is 58% of invoiced value; commercial clients typically require ACH or check, pay after 52 days, and may not accept a card surcharge on a $3,800 invoice. Eleven of 14 interviewed mostly-commercial customers said their clients require ACH or check. By contrast, the pilot’s customers were 64% residential, against 42% for Fieldline overall. And 71 of the 115 largest customers have processor contracts running mostly to 2028; the largest 5% of customers account for 48% of invoiced value. The pilot’s 61% adoption is encouraging, but it does not establish broad adoption or broad monetization. Tradesly’s 22% revenue share is also a weak comparator: its customer base is about 80% residential.

A more defensible annualized revenue range

The following estimates are run-rate scenarios, not a forecast. They use the supplied 61% pilot adoption rate and 70% plan assumption as bounds, and make explicit that the take depends on payment type.

Card revenue: Current recorded payment methods show 19% of invoice value paid by card. In the pilot, the reported card shares imply a 33.3% value-weighted card share if applied to our mix: 42% residential × 71% + 58% commercial × 6% = 33.3%.

At a 0.7% net card take:

• Lower case: $4.83B × 61% adoption × 19% card share × 0.7% = $3.9M
• Upper case: $4.83B × 70% adoption × 33.3% card share × 0.7% = $7.9M

The upper case assumes pilot card behavior transfers to the full customer mix, despite the pilot’s residential skew.

ACH revenue: The recorded-method sample reports ACH at 44% of invoice value, but value share does not tell us the number of $2 ACH payments—and the pilot does not report ACH usage. As an illustrative bound, if that 44% share transferred to adopters, ACH revenue would be about $0.5M–$2.1M after the $0.40 cost: the lower end assumes ACH dollars are mostly $3,800 commercial invoices; the upper end allows the pilot’s card mix and available non-card residential volume. This is uncertain upside, not a reliable forecast.

Together, that supports roughly $4.5M–$10M of annualized revenue, before accounting for contract lock-in or slower adoption among large accounts.¹ The range is still conditional on transferring today’s payment mix and pilot behavior to adopters. As a cross-check, the pilot’s $214K annualized revenue across 38 customers is $5,630 per customer; scaling that to 61%–70% adoption gives $7.9M–$9.1M. That sits within the range, but is not a clean base case because the pilot skewed residential.

The $24M case requires $14,700 per adopting customer per year ($2.1M × 0.7%). That is about 2.6× the pilot’s $5,630, while assuming adoption and monetization across a materially more commercial customer base.

What would change my mind—and the cheapest six-week test

I would support a larger bet if a representative cohort showed both credible adoption and enough net revenue per adopter to approach the $14,700 annualized level the board case requires—especially among commercial customers and larger accounts not locked into existing processors. A high signup rate alone would not prove the economics.

Run a six-week, no-build test using the existing pay-by-link and partner setup. Recruit a small, stratified cohort across residential and commercial customers, including larger unlocked accounts. Track offers accepted, invoice value actually routed, card versus ACH mix, net revenue after costs, and payment timing. Report results by segment; do not annualize a handful of unusually large or residential-heavy customers as if they were representative. Include a holdout or compare with each customer’s recent invoices to distinguish new payment volume from existing behavior.

Recommendation

Do not commit three squads for three quarters or pause the scheduling rewrite on the current evidence. The rewrite addresses the top-cited churn reason among customers with more than 50 technicians, a segment that lost $1.9M ARR last year. Run the six-week test with a small team and existing capabilities, then make a stage-gated decision. If commercial routing and net revenue per adopter are strong, fund the next increment. If not, preserve the scheduling investment and narrow Pay to the segments where the data shows customers can—and will—use it.

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.
