Challenge an idea

To: Priya Raman; CEO; CFO; Head of Sales From: Staff PM Subject: Fieldline Pay: challenge the revenue thesis before committing three squads

Recommendation

Do not commit three squads for three quarters or pause the scheduling rewrite. Authorize a six-week commercial test using the existing pilot product and partner.

Embedded payments may be worth building. The evidence does not support presenting $24M as an expected month-24 revenue run-rate. My scenario range is approximately $2–$10M annualized, with $10M an optimistic case—not a base case.

1. The unsupported assumption: adopted invoice dollars yield 0.7%

The plan’s most consequential assumption is that the invoice value belonging to adopting customers becomes payment volume earning a blended 0.7% net take.

That is card economics applied to all invoices. It conflates three things: adopting Fieldline Pay, routing payments through it, and choosing a profitable payment method.

The available evidence contradicts it:

• Only 19% of recorded payment value is card. ACH is 44%; checks and cash are 37%. These observations cover 30% of customers, so representativeness remains unproven.
• ACH does not yield 0.7%. We earn $1.60 per payment. At the average commercial invoice of $3,800, that is 0.042%; at the residential average of $410, 0.390%.
• Commercial work is 58% of invoice value. Even in the pilot, commercial card share reached only 6%, versus 71% for residential. A 2.9% card fee on a $3,800 invoice is about $110, before the fixed charge. Sales and interviews both indicate resistance to that fee.
• The pilot overweights our best payments segment: 64% residential versus 42% across Fieldline. Tradesly’s roughly 80% residential customer mix makes its revenue share a poor benchmark for ours.

Volume concentration compounds the error. The largest 115 customers supply 48% of invoice value; 71 have processor contracts, mostly through 2028. We do not know those 71 customers’ exact volume, but cannot assume their invoices are available.

Consequently, 70% customer adoption does not establish 70% volume capture. The $2.1M average also obscures this concentration: the median is $640k, and customers outside the largest 5% average only $1.15M.

2. Re-estimate: approximately $2–$10M annualized

Use:

Revenue = eligible invoice value × adoption × routed share × payment-method yield.

The following scenarios assume adopters route all eligible invoices through Pay. That is generous. They use today’s customer base, not unsupported customer growth, and are scenarios rather than a statistical confidence interval.

Conservative scenario: approximately $2.3M

Assumptions:

• Exclude the entire largest-5% cohort pending evidence of access. This is a conservative scenario, not a claim that all 115 are contractually blocked.
• Remaining invoice value: $4.83B − $2.32B = $2.51B.
• Adoption: pilot’s 61%.
• Retain today’s 19% card and 44% ACH value shares; checks and cash earn nothing.
• Value ACH at the commercial invoice size. This produces the lower ACH yield.

Blended yield:

19% × 0.7% + 44% × ($1.60 ÷ $3,800) = 0.152%.

Revenue:

$2.51B × 61% × 0.152% ≈ $2.3M.

This assumes the remaining cohort has the overall payment mix; the pack does not provide its actual mix.

Optimistic scenario: approximately $10.3M

Assumptions:

• All $4.83B is accessible, despite processor contracts.
• 70% adoption also captures 70% of invoice value.
• Pilot card conversion transfers to Fieldline’s actual job mix.
• Every non-card dollar becomes ACH: no checks, cash or external payments.

Card value share:

42% × 71% + 58% × 6% = 33.3%.

Blended yield, using job-specific invoice sizes:

33.3% × 0.7% + [42% × 29% × ($1.60 ÷ $410)] + [58% × 94% × ($1.60 ÷ $3,800)] = 0.304%.

Revenue:

$4.83B × 70% × 0.304% ≈ $10.3M.

Even this unusually favorable case is 57% below the CFO’s $23.7M.

A separate cross-check is the pilot’s actual monetization: 1,610 adopters × $5,630 = $9.1M. That is not a forecast: the pilot is residential-heavy, and we lack its invoice-volume denominator. But it does not validate $24M.

The range could fall below $2M if adoption or routing disappoints. We lack the data to assign probabilities.

3. What would prove this challenge wrong?

To generate $24M from $4.83B, Fieldline needs portfolio-wide annual net yield of approximately 0.50%. At 70% volume capture, captured payments must yield approximately 0.71%.

We would need evidence of either:

1. Much more accessible, routed, high-margin card volume than today’s mix and pilot suggest; or
2. A demonstrably profitable additional fee or product customers will actually pay for.

Adoption percentages, enthusiasm and competitor revenue shares would not suffice.

Cheapest six-week test

Use the existing pay-by-link product and partner; no new platform build.

Recruit approximately 50 non-pilot customers, stratified by invoice volume and residential/commercial mix, including a deliberate sample of large accounts with processor contracts. Weight results by invoice dollars, not customer count.

For each, establish contractual access and offer Pay at intended production pricing. Measure:

• Activation and actual routed invoice value;
• Card/ACH/check mix, invoice sizes and realized net revenue;
• Payer refusals, especially commercial surcharge refusals;
• Large-account willingness and ability to switch.

Commercial invoices take 52 days to pay on average. Include existing invoices due during the test, not just newly issued invoices, and report unpaid invoices separately rather than assuming conversion.

The test passes only if observed economics and credible volume-access commitments support a transparent path to $24M. A small test cannot prove 18-month adoption, but it can cheaply falsify the unit economics or access thesis.

4. Change the bet

Keep the scheduling rewrite staffed. It addresses the top-cited churn reason in a segment that lost $1.9M ARR last year; postponing it has a concrete opportunity cost ahead of our raise.

If the test supports attractive economics, fund a narrower, stage-gated residential payments rollout—not the current commitment.

Separately, test commercial customers’ willingness to pay for faster collection. Seventeen of 22 interviewees identified commercial payment delays as their biggest cash problem; nine would pay to get paid faster. Payments acceptance does not itself solve net-60 terms. Explore collections workflows or partner-funded acceleration before underwriting a financing business.

Finally, reset the board’s expectation now: $24M is an unvalidated upside hypothesis, not an evidence-backed plan.

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.
