Stop writing invoices by hand or chasing customers for payment. Here's the fastest way to invoice your plumbing customers and get paid the same day.
As a plumber, your time is money. Every minute you spend writing invoices, following up on unpaid bills, or explaining how to pay is money out of your pocket. The right invoice app changes all of that — and in 2026, there's no excuse for not having one.
We'll walk through what makes a great invoice app for plumbers specifically, what to look for, and why FieldPay was built with trades contractors like you in mind.
Most invoicing apps are built for freelancers and office workers — not plumbers crawling under sinks or finishing a job in someone's basement. Here's what matters for a plumber:
Apps like QuickBooks, FreshBooks, and Wave are powerful — but they're designed for businesses with accountants and office staff. They're complicated, expensive, and overkill for a plumber running a small operation. You don't need double-entry bookkeeping. You need to get paid.
On the other end, basic apps like Invoice Simple are too bare-bones. They don't handle per-line tax correctly, don't send reminders, and don't make it easy for customers to pay digitally.
FieldPay was designed from the ground up for trades contractors — including plumbers. Here's what makes it different:
Finish a job, pull out your phone, tap +, select the customer, add your line items, and hit send. Your customer gets a professional invoice link via text or email before you've even started your truck. No laptop required.
Plumbing jobs often mix taxable materials (pipe fittings, fixtures, parts) with non-taxable labor. FieldPay lets you mark each line item as taxable or not — and calculates the correct tax automatically. Your customers see a clean breakdown every time.
Save your standard rates — "Service call — $85", "Emergency rate — $150/hr", "Parts markup" — and tap them when building an invoice. Never retype the same prices twice.
Every invoice shows your PayPal, CashApp, and Venmo handles automatically. Customers can also pay by credit card through PayPal — no PayPal account required. Cash and check instructions are included too.
Set a reminder threshold — say 3 days — and FieldPay flags any unpaid invoices that are overdue. Resend a follow-up text or email with one tap. Stop chasing customers manually.
💡 The average contractor spends 3-5 hours per week on invoicing and payment follow-up. FieldPay users cut that down to under 30 minutes.
FieldPay is $24/month for a solo plumber — that includes everything. No per-invoice fees, no hidden charges, no "premium" features locked behind a higher tier. Compare that to Jobber at $49-$129/month or Housecall Pro at $65-$169/month.
For a plumber doing 10-20 jobs a month, FieldPay pays for itself the first time you get paid faster because you sent a professional invoice instead of a handwritten receipt.
Setup takes about 5 minutes. Create your account, enter your business name and tax rate, add your PayPal/CashApp/Venmo handles, and you're ready to send your first invoice. There's a 14-day free trial — no credit card required to start.
