The Hidden Bill in Field Service Software: Payment Processing Rates Compared

The line nobody puts on the pricing page

Field service software ads lead with $49 or $129 a month. The number that actually moves the P&L is the percentage taken when the customer taps Pay. A 3-truck shop running $40,000 a month through cards at 2.99% pays about $1,200 a month in processing — four to eight times the software bill. Per-tech subscription math is the first TCO lever. This is the second.

How the platforms charge

Three models, same customer card:

Bundled processor. The FSM is the merchant of record. Rates are a published ladder (card-present vs online vs keyed). Housecall Pro Payments works this way.
Jobber Payments. Same idea, rates shown in the Jobber Payments settings and commonly reported as 2.9% + $0.30 on keyed/online cards.
Stripe through the FSM, no markup. GridBoss uses Stripe. You keep 100% minus the plan rate — 2.9% Starter, 2.5% Pro, 1.9% Business — with no statement fee or platform add-on. Stripe's cost is real; the claim is the software is not taking a cut on top.

The 2026 rate card

Competitor figures below are what those companies publish or what independent 2026 breakdowns consistently report. Confirm against your own statements — blended rate (Amex mix, keyed-in cards, instant payout) is what you actually pay, not the homepage number.

	Card present / tap	Online invoice	Keyed / Amex	ACH	Instant payout
Housecall Pro	2.59%	2.99%	3.49%	1%	+1% (Instapay)
Jobber Payments	2.7% + $0.30	2.9% + $0.30	2.9% + $0.30	1% (US)	+1%
GridBoss	2.9 / 2.5 / 1.9%	2.9 / 2.5 / 1.9%	2.9 / 2.5 / 1.9%	Included via Stripe	Stripe standard (usually 2 business days)

Housecall Pro's ladder is from their own help center. Jobber's card and ACH rates are what shops see in Jobber Payments settings and what 2026 pricing writeups repeat; tap-to-pay is the discounted presentment rate. GridBoss rates are the plan prices on the pricing table.

Worked example: $40k/month in cards

Eight-person plumbing shop. $40,000 a month collected on card, mostly from emailed invoices — the common path when the tech sends a link from the truck.

Housecall Pro at 2.99% online: $1,196/month, $14,352/year.
Jobber at 2.9% + $0.30, say 160 invoices/month: roughly $1,208/month.
GridBoss Business at 1.9%: $760/month, $9,120/year.

Annual delta vs Housecall Pro online: about $5,200 — before you count Instapay, keyed-in commercial cards at 3.49%, or the software subscription itself. Move a third of that book to ACH at ~1% and the savings stack again, on any platform that offers it.

Side-by-sides for the rest of the product: vs Housecall Pro, vs Jobber, vs ServiceTitan.

Rate vs speed

A cheaper percentage on an invoice that sits for 21 days is still a cash-flow problem. The move that usually beats another 20 basis points:

Tech marks the job complete.
Invoice goes out with a payment link in the same SMS.
Customer pays before the truck leaves the driveway, or that evening.

Shops that do this routinely cut days sales outstanding in half within a month. GridBoss sends that link from the job. So do the incumbents. The difference is what they take when the card hits.

What you give up for a cheaper rate

Be honest about the extras bundled into a higher processing bill:

Consumer financing / BNPL partners (Housecall Pro prices these separately, and they are the right tool for $8k+ replacements).
Instant payout (Instapay / Jobber instant) if you genuinely need money the same afternoon — that 1% is a cash-advance fee, not a processing rate.
A polished tap-to-pay reader workflow if most of your collection happens at the kitchen table, not on a link.

If those are how you close, keep them. If you are paying 2.99% on emailed invoices for a reader you do not use and financing you run through a bank anyway, you are donating basis points.

How to read your own statement

Pull last month's processing report from your current platform. Ignore the advertised rate. Divide fees by volume. That is your blended rate.
Split the book: emailed invoice vs keyed vs present vs ACH vs instant payout.
Reprice the emailed-invoice slice at 1.9% and at 2.5%. That is the GridBoss Pro vs Business question.
If you are also paying per-user add-ons, add the subscription delta. The two numbers together are the real switch math.

Want it run on your statement instead of a hypothetical? Book 30 minutes or start a 14-day trial and connect Stripe. If the rate is not better for your mix, we'll say so.
