Running a plumbing business means your office is wherever the van is parked. You diagnose the problem, fix it, and then — too often — you wait. You wait for a check that never arrives, a card that gets declined at the door, or an invoice you sent by email that sat unread for two weeks. Payment friction is one of the biggest hidden costs in the trades, and most plumbers are paying more than they should on every card swipe while also losing hours to collections. This guide covers field invoicing, deposits, dispatch, and financing — and shows you exactly where the money leaks so you can stop it.
Why Plumbers Overpay on Card Processing
Most plumbing businesses end up on flat-rate or tiered pricing because that is what Square, Stripe, or the bank offered when they signed up. Flat-rate sounds simple — 2.6% plus ten cents, or 2.9% plus thirty cents — but simple is expensive when your average ticket is $400 to $2,000.
At a 2.9% flat rate, a $1,200 repair job costs you $34.80 in card fees. At wholesale interchange-plus pricing starting at 1.7%*, that same job costs closer to $20.40 in illustrative terms. That $14 difference sounds small until you run 80 jobs a month. Over a year, the gap is real money that belongs in your pocket, not your processor's.
The chart below shows illustrative effective rates across common pricing models. These are estimates — your actual rate depends on your card mix and ticket size.
Wholesale interchange-plus means you pay the actual card network cost plus a small, transparent margin. Nothing is bundled, nothing is padded. You can see every line on your statement.
What Happens at the Door: Field Invoicing Done Right
A plumber who cannot invoice and collect on the spot is leaving money on the table. The job is done, the customer is happy, and that is the single best moment to get paid. Every hour between job completion and payment collection is a risk.
With Pocket Boss, our AI-enhanced Business in a Box, your tech can close the invoice from their phone before they pull out of the driveway. The customer gets a text with a payment link. They tap, they pay, done. No paper invoice. No follow-up call. No waiting for a check to clear.
Text-to-pay changes collection time dramatically. When a customer receives a payment link by text immediately after the job, they pay while the experience is fresh. When they receive a PDF by email two days later, they file it under "deal with later."
Pocket Boss Start is $100 per month with no setup fee and includes CRM, texting, invoicing, scheduling, and our AI assistant Alli. For most solo operators or small crews, that single subscription replaces the invoicing app, the scheduling tool, the follow-up reminder system, and the customer database they are currently paying for separately.
Should You Collect a Deposit Before the Job Starts?
Yes, almost always — especially for larger jobs. A $4,000 water heater replacement or a $6,000 repipe should never start without money down. Deposits protect you from no-shows, material costs, and customers who disappear after the work is done.
With a card-on-file workflow, you collect the deposit at booking and charge the balance at completion. No awkward conversation at the door. The customer agreed to the terms when they scheduled, and the system handles the rest automatically.
Here is the math on a $5,000 job with a 50% deposit collected by ACH:
- Deposit: $2,500 via ACH — fee is $22.50 (0.9%, capped at $1,000 per transfer)
- Balance: $2,500 via card at 1.7%* — illustrative fee around $42.50
- Total fees: roughly $65
Compare that to running the full $5,000 on a flat-rate card at 2.9%: $145 in fees. The hybrid approach — ACH for the deposit, card for the balance — saves roughly $80 on a single job in this illustrative example. Run ten jobs like that a month and the savings compound fast.
Our ACH pricing is 0.9% or 50 cents, whichever is greater, capped at $1,000 per transfer. For large invoices, that cap is significant.
How Dispatch and Scheduling Connect to Getting Paid
Dispatch is not just a logistics problem — it is a cash flow problem. Every unbooked slot, every no-show, and every job that runs long without a clear handoff to billing is money lost.
Pocket Boss connects scheduling and invoicing in one place. When a job is marked complete in the dispatch board, the invoice triggers automatically. The customer gets a text. The tech gets a notification. Nothing falls through the cracks because there is no gap between the field and the back office.
For multi-tech operations, this matters even more. When you have four trucks running, you cannot manually track who finished what and whether the invoice went out. Automation handles the handoff so your office staff — or you — are not chasing paperwork at 6 p.m.
| Task | Manual Process | With Pocket Boss |
|---|---|---|
| Send invoice after job | 1–2 days, email, often ignored | Instant text link at job close |
| Collect deposit at booking | Phone call, hope they pay | Card-on-file captured at scheduling |
| Follow up on unpaid invoice | Staff time, awkward calls | Automated reminder sequence |
| Sync job to customer record | Manual data entry | Auto-logged in CRM |
| Dispatch next job to tech | Phone or separate app | Unified board in Pocket Boss |
Does Offering Financing Help You Close Bigger Jobs?
It does, and it is worth building into your sales process. When a customer hears that a full repipe is $8,000, some of them say no — not because they do not want the work done, but because they cannot write that check today. Offering a payment plan or third-party financing turns a lost job into a booked job.
The processing side of financing varies by provider, and we can help you think through how to structure it. What matters for your cash flow is understanding who pays the financing fee, whether you receive funds immediately, and how that affects your effective cost per job. These are questions worth asking before you commit to any financing partner.
What we handle on our end: the invoicing, the deposit workflow, the card-on-file, and the ACH option for customers who want to pay by bank transfer. The combination of payment options — card, ACH, text-to-pay, card-on-file — means fewer customers hit a wall when it is time to pay.
What Does a Wholesale Statement Actually Look Like for a Plumber?
On a wholesale interchange-plus statement, every line is visible. You see the interchange category, the network assessment, and our margin separately. Nothing is bundled into a single mystery rate.
For a plumbing business, most transactions run as card-present (tap or dip at the door) which qualifies for lower interchange than keyed or online payments. If your techs are keying cards manually in the field because they do not have a reader, you are paying a card-not-present premium on every one of those jobs. That is a fixable problem.
We review your current statement for free. We show you exactly what you are paying, what category your transactions fall into, and what a realistic wholesale rate looks like for your business. No pressure, no commitment — just the math.
