Plumbing Contractor Software
Werx is the office software for plumbing contractors who want to bill faster and protect margins. Run estimates, progress and AIA-style billing, job costing, and field time. Then sync it all to QuickBooks.
- Progress and AIA-style billing for commercial jobs
- T&M invoicing for service calls
- Two-way QuickBooks Online sync
Stop the busywork
Bill commercial plumbing work without the spreadsheets
Commercial plumbing bills on a schedule of values with retainage, while service calls bill T&M. When billing and job costs live in spreadsheets, margin leaks and cash comes in slow. The waiting is normal, and that is the problem: in [Billd's 2026 National Subcontractor Market Report](https://billd.com/resources/2026-market-report/), 64% of subcontractors reported slow payment from GCs, waiting an average of 51 days.
- Build pay apps in Excel
- Forget retainage
- Change orders unbilled
- Job costs after the fact
- G702 and G703 style pay apps built for you
- Retainage tracked
- Change orders billed
- Job costs in real time
Werx gets plumbing contractors out of spreadsheets. Estimate, bill progress and T&M, track job costs, and get paid in one app.
The money side of a plumbing business for $49 a month
Construction billing and job costing platforms publish entry prices from $149 to $599 a month, with per-user fees up to $20 and features like job costing often gated to higher tiers (as of July 2026). Werx takes the opposite approach: flat plans from $49 a month, every feature on every plan, and users are $6.
For a plumbing shop, that is less than one drain call a month to run the entire office side. See pricing for the full breakdown, or compare Werx to the platforms you are looking at.
- Every feature on every plan, from day one
- AIA-style billing, T&M invoicing, estimates, and job costing included
- Users are $6 a month, time-only users $4, no caps
- No contracts, 14-day free trial, no credit card
Where plumbing contractors lose money
Most lost margin hides in billing and job costs. Here is where it slips, and how Werx catches it.
Commercial jobs stuck in paperwork
GCs want G702 and G703 style pay apps. Werx builds them from your schedule of values.
AIA billingRetainage you forget to chase
Retainage of 5 to 10 percent adds up across jobs. Werx tracks it on every pay app.
Progress billingUnbilled change orders
Extra work in the field often never gets billed. Werx turns field tickets into billable change orders.
Change ordersLate service invoices
Service calls billed days later slow your cash. Invoice T&M work the same day.
Time and material invoicingNo live job costs
Without real-time costs, you find losses too late. Werx shows budget versus actual by cost code.

Bill an AIA-style pay app and get paid
Commercial plumbing work bills on a schedule of values, not a flat invoice. Werx builds the G702 and G703 style pay application for you.
Set percent complete on each line. Werx calculates retainage and the current payment due. No spreadsheet, no math errors.
Send the pay app to the GC through a branded portal. They review and pay online. Learn more about AIA billing and what AIA billing is.
How plumbing work bills in Werx
Plumbing money comes in two shapes, and Werx handles both. A service call bills the day it happens. Say a tech spends 3 hours on a water heater swap at $145 an hour. That is $435 in labor. The heater, pan, expansion tank, and fittings cost you $1,180, and at 25 percent markup they bill at $1,475. The invoice totals $1,910, built from the tech's logged hours and real material costs, not from memory a week later.
A commercial rough-in bills nothing like that. Take a $90,000 plumbing package on a medical office building, billed monthly by percent complete with 10 percent retainage. Partway through, the schedule of values might look like this:
| SOV line | Scheduled value | % complete | Earned to date |
|---|---|---|---|
| Underground rough-in | $18,000 | 100% | $18,000 |
| Above-ground rough-in | $36,000 | 75% | $27,000 |
| Water heaters and equipment | $9,000 | 40% | $3,600 |
| Fixtures and trim | $22,000 | 0% | $0 |
| Inspection and closeout | $5,000 | 0% | $0 |
| Total | $90,000 | 54% | $48,600 |
Set the percent complete on each line and Werx builds the G702 and G703 style pay application: $48,600 earned, $4,860 held as retainage, prior billings subtracted, current payment due calculated. Nothing lives in a spreadsheet, so nothing ties out wrong. The same percent complete data feeds WIP reporting when your bank or bonding agent asks where jobs stand. New to billing on an SOV?

Why plumbing contractors choose Werx
Most field apps skip the hard part: real billing and job costing. Werx is built for it.
Built for the trades
Made for contractors who bill commercial and residential work, not a plain invoice tool.
Real AIA-style billing
G702 and G703 style pay apps with retainage. Most small-shop tools cannot do this.
Know your margin
Live job costs and profit on every job, so you catch losses while you can still fix them.
Works with QuickBooks
Two-way sync with QuickBooks Online on every plan, at no extra cost.
One office system
Estimates, billing, costs, time, and payments in one place. No juggling apps.
Service invoices and pay apps, one set of books
Most plumbing companies already run QuickBooks Online, and the bookkeeper does not want a new system. Werx connects to it instead of replacing it. Every T&M invoice, every pay app, every payment and job expense syncs both ways, so nothing gets keyed twice and nothing goes missing between the job side and the books. At month end, the two already agree.

Read the guideWhat is plumbing contractor software?
Plumbing contractor software is an office tool that handles estimates, billing, job costs, and payments for plumbing companies. It replaces spreadsheets and paper for the money side of the business.
It is also a crowded trade to stand out in. The U.S. has 111,207 plumbing, heating, and air-conditioning contractor establishments per the Census Bureau's 2023 County Business Patterns. The Bureau of Labor Statistics counted 504,500 plumbers, pipefitters, and steamfitters working in 2024, projects 5 percent growth by 2034 with about 44,000 openings a year, and puts median pay at $63,800 as of May 2025. In a field that size, the shops that win are the ones whose billing keeps up.
Werx is built for both sides of plumbing work. Bill commercial jobs with progress and AIA-style billing. Invoice service calls with time and materials.
Track labor from the field, see job costs in real time, and sync to QuickBooks. You bid, bill, and get paid from one place.
