Estimating & invoicing software built for plumbing contractors
Quote repipes, water heaters and bathroom rough-ins in minutes with AI that knows plumbing — then invoice and get paid from the same app. From $39/month (1 user; add teammates at your plan’s per-seat rate). 0% platform fee on payments.
Built around how plumbers actually work
Quoting from the crawlspace
The customer wants a number before you’ve washed your hands. Describe the job in plain English — “40-gal gas water heater swap, second floor closet” — and the AI drafts priced line items you can adjust and send from the driveway.
“While you’re under there…”
Every plumber knows the sentence. Capture the extra fixture or the corroded shutoff as a change order on the spot — priced, customer-approved in the portal, and on the final invoice. (Client portal and change orders are included from the Pro plan.)
Emergency work, slow money
You showed up at 9 PM for the burst pipe — the check shouldn’t take six weeks. Online card/ACH payment with 0% platform fee, automatic reminders, and optional late fees.
Everything between “can you quote this?” and “paid”
Estimate → invoice → paid
- AI estimates that know plumbing scopes — repipes, rough-ins, fixture counts, water heaters
- Three-tier quotes (repair / replace / upgrade) that let customers choose up
- Estimate converts to invoice in one tap; online payment with 0% platform fee
- Automatic payment reminders — you fix pipes, not chase checks
Run the crew & the paperwork
- GPS time tracking with geofenced job sites for multi-crew days
- Photo-documented daily logs — before/after under every sink and slab (Pro plan and up)
- Permits tracked per job with expiry reminders (Pro plan and up)
- Free business page that captures leads while you’re on a call — no per-lead fees

The photo trail that ends “you never told me” calls
Every panel, fixture or unit photographed from the phone, timestamped and attached to the job. When a customer disputes a change, plumbing contractors open the log instead of arguing from memory — and the customer sees the same photos in the portal (daily logs and the portal are on Pro and up).

What’s the best invoicing software for a small plumbing company?+
A small plumbing shop needs fast invoices on-site, online payment (card and ACH), automatic reminders, and estimates in the same app — with users included in the plan and extra seats at a flat per-seat rate. FieldsHub does that from $39/month with a 0% platform fee on payments. Shops built purely around dispatch/membership plans may also evaluate dedicated field-service dispatch tools.
Can it estimate a repipe or bathroom rough-in?+
Yes — describe the scope (“copper-to-PEX repipe, 2 bath, slab foundation”) and the AI drafts line items with quantities and typical pricing as a starting point. Your rates and markup apply; you review everything before it goes out.
Does it work for service-and-repair as well as remodel jobs?+
Both — one-line service invoices with payment links for repairs, and multi-phase estimates with change orders and progress invoicing for remodels and new construction. (Client portal and change orders are included from the Pro plan.)
Calculator figures are ballpark ranges from national averages — real jobs vary by region, access and scope. See how FieldsHub compares to other tools on the comparisons page.
