What a Plumber job looks like in SideWRK.
The plumber job as the app lays it out — your own cost sitting on it, and the estimate your customer approves from their phone.
Built for licensed plumbing work — in one app
Permit & inspection tracking
Water-heater, gas-line, and repipe permits get their own panel: record the permit number and authority, move it from needed to applied to issued to passed, and log the rough-in and final inspections with dates. You always know if you're waiting on the city or clear to cover the trench.
License & permit # on every invoice
The invoice carries your plumbing license and the job's permit number without you typing either twice — the inspector's sign-off and the bill live on the same paper trail.
Permit fees, billed right
Paid the city for the water-heater permit? Add permit fee passes it through at exactly what it cost you — its own line on the invoice, no markup, and your real-profit math stays honest.
Customers approve from their phone
The customer opens a branded link, reads the scope, checks the photos of the corroded line, and taps Approve — name, time, and amount logged. Open the wall and find more? They authorize the new total before you sweat another joint.
Real profit, not just revenue
Every fitting and fixture carries a private "your cost" the customer never sees — so the Money tab shows what you actually made on each job, not just what you charged.
Photos that document the work
Snap the corroded line, the failed water heater, or the finished repipe and text it to the customer — proof that gets jobs approved and a record of the work before it's buried in a wall.

Estimate. Invoice. Get paid.
SideWRK runs the business side from your phone, on the job.
Estimate the call, invoice it when it's done, and see what it actually cleared — with every property and customer on file.
From service call to "paid" in three steps
Write it up
Add the property and what's leaking, then the work — labor, fittings, a photo — and mark whether the job pulls a permit. Send the branded estimate.
Permit & inspect
Record the permit number when it's issued, log rough-in and final as they pass, and pass the fee through at cost. The invoice carries all of it.
Get paid
Approved, invoiced, paid — the numbered invoice prints your license and the permit, and the Money tab shows what the job really made you.
What should a plumber charge?
Plumbing is usually priced with a service-call fee plus flat-rate or hourly work, with a premium for emergencies. Here's how it's priced, plus free calculators to find your number.
Service-call fee
Most plumbers charge a service-call fee of about $75–$150 to show up and diagnose, often credited toward the repair.
Flat-rate or hourly
Repairs are flat-rate by job or hourly — commonly around $80–$140 an hour. Customers usually prefer a flat number they approve up front.
Fixtures, access, emergencies
Fixtures and materials carry a markup; tight access and old plumbing add time; after-hours and emergency calls justify a premium.
Plumbing calculator
Before you quote the water heater swap, know the hourly number it has to clear.
The plumber rate behind SideWRK's estimating defaults is $110/hr, with 60% of a typical ticket paying for time rather than materials. Both numbers come from our 2026 Side-Work Rate Report, which publishes the same figures for all 42 trades.

Plumber FAQ
Does SideWRK handle plumbing permits and inspections?

How do I bill a permit fee?
Tap Add permit fee and put in what the city charged you. It lands on the invoice as its own pass-through line at cost — no markup by default — so the customer sees it plainly and your profit math stays true.
Does my license number show on invoices?
Yes. Your plumbing license number and the job's permit number both print on every estimate and invoice automatically — a clean paper trail for you and the customer.
