Finish the job, send a professional plumbing invoice from your phone, and get paid before you leave the driveway. No paperwork. No chasing.
Plumbers spend an average of 3-5 hours per week on invoicing and chasing payments. That's unbillable time that directly costs you money. The right plumbing invoice app eliminates that entirely — you invoice on site, your customer pays digitally, and your records update automatically.
Here's everything you need to know about choosing the best plumbing invoice app in 2026.
Finish the job, open FieldPay, tap +, select the customer, add your line items using saved rates, and send. Your customer gets a professional plumbing invoice link via text or email before you've cleaned up. The invoice shows your company name, every part and labor charge, the tax breakdown, and all payment options.
Plumbing jobs mix taxable materials — pipe fittings, valves, water heaters, fixtures — with non-taxable labor. In FieldPay each line item has a T toggle. Mark materials as taxable, labor as not. The tax calculation is automatic and the customer sees a clean breakdown showing exactly what was taxed and why.
Save your standard charges once — "Service call $85", "Plumbing labor $95/hr", "Emergency call $150", "Water heater installation $200", "Drain cleaning $125" — and tap them when building any invoice. Your most common plumbing charges are always one tap away.
Send the invoice, show the customer their phone, and watch them pay via CashApp or Venmo right in front of you. Or tap the PayPal button and pay by credit card. Customers who receive invoices immediately and have a tap-to-pay link pay on the spot far more often than those who receive paper invoices or emailed PDFs days later.
Need a hard copy for a property manager or insurance claim? Print any plumbing invoice with one tap — a clean, professional page with your company name, full line items, and tax breakdown. Works from your phone and desktop.
💡 Plumbers who invoice immediately after the job and offer digital payment collect an average of 11 days faster than those who mail paper invoices or send PDF attachments.
QuickBooks is an accounting platform built for office workers — not plumbers finishing a job under a sink. It requires a laptop, has a steep learning curve, and costs $30-$200/month. FieldPay is designed to be used on your phone, one-handed, in a customer's basement. It costs $24/month and takes 5 minutes to set up.
QuickBooks is worth considering if you need full accounting with payroll, inventory, and bank reconciliation. If you mainly need to invoice plumbing jobs and get paid — FieldPay does that better and for a fraction of the cost.
