The card fee problem for plumbers
Emergency calls mean high tickets — and card fees compound fast on every job.
Plumbing work is high-stakes and high-ticket. A sewer line repair runs $3,000–$8,000. A water heater replacement is $1,200–$3,500. An emergency call on a Saturday night commands a premium. When customers pay by card — and most of them do — you're eating $35–$232 per job in card processing fees that most plumbing invoicing software just ignores.
KoPay gives plumbers a direct solution. KoPay automatically calculates the processing fee and adds it to every invoice as a transparent line item. The customer sees the fee before they confirm payment. You receive your full quoted amount — labor, materials, emergency surcharges, and all.
For a plumbing company running 5 service calls per day at an average of $400, that's $500,000 in annual revenue. At 65% card payment rate, you're processing $325,000 in card transactions. Standard processing fees eat roughly $9,425 of that every year. With KoPay, that $9,425 goes to customers instead of your payment processor.
KoPay was built for businesses exactly like yours — field service, fast-moving, high-ticket, and often waiting too long to get paid. Our fee pass-through, digital estimates, and Stripe-powered pay links are built to fix the billing problems that have always slowed plumbing companies down.

Service calls, repairs, and fixture installs done right. Invoice from your phone, let customers pay online, and keep a clean record of every job and customer without extra paperwork.

Line-item estimates for rough-in, fixture installation, and trim-out phases. Deposit invoices before the job, progress invoices mid-project, final invoice at completion.
Multi-Truck Operations
Office dispatchers manage customers and invoices. Field plumbers create estimates and invoices on-site. Role-based access keeps everyone in sync without extra overhead.
The real math
What fee pass-through recovers for a $300K plumbing company
Consider a residential plumbing company billing $300,000 per year across service calls, repairs, and small remodels. The average job runs $380. About 65% of customers pay by card. That's $195,000 in card transactions annually.
At standard Stripe rates (2.9% + $0.30 per transaction), the processing cost on those transactions is roughly $5,655 per year — absorbed silently without KoPay.
With KoPay, that $5,655 moves to customer invoices as a transparent line item. Over three years, the business recovers $16,965. Over five years, $28,275 — enough to cover a truck payment or fund a significant equipment purchase.
Most plumbers never run this math. They accept card fees as the cost of doing business. KoPay fixes that assumption automatically — no pricing change, no renegotiation, no awkward conversation. Just a line on every invoice that shows customers exactly what the card fee costs before they tap to pay.
