The Best Invoice App for Plumbers in 2026

Stop doing paperwork at 9 PM. Here is the toolstack for the modern plumber.

You just spent 3 hours under a sink. Your hands are wet. You are late for the next job. The last thing you want to do is tap out a detailed invoice on a tiny screen.

Plumbers face a unique challenge: Messy hands and complex parts lists.Typing "1/2 inch copper coupling" ten times a day is a waste of life.

🏆 The Winner: VoiceInvoice

Hands-Free Input: Perfect for when your hands are dirty. Just talk.

Smart Parts Dictation: Say "Replace P-trap and supply lines, 150 labor," and it formats it perfectly.

Speed: Finish the billing before you even start the engine.

The Runner Ups

2. Housecall Pro

Best for: Multi-van plumbing companies.

If you have 3+ dispatchers and need to track inventory across vans, Housecall Pro is the gold standard. It handles dispatch, inventory, and marketing. But for a solo plumber, it's expensive overkill.

3. ServiceTitan

Best for: Enterprise commercial plumbing.

The Ferrari of field service. Costs a fortune, does everything. If you are doing million-dollar commercial contracts, verify this. If you are fixing leaks, stay away.

4. Invoice Simple

Best for: Basic PDF generation.

Does one thing well: makes PDFs. But you still have to type everything manually. In 2026, manual data entry is a competitive disadvantage.
