Office work used to take a bull and your profit.
Bidding, billing, payroll, the books — the back-office heavy lifting that ate your nights and weekends. Now Bullwork does the heavy lifting, so you can focus on the build and keep more of what you earn.

Learn more →Most contractors run four tools that don’t talk.
A PM app for the jobs. QuickBooks for the books. A payroll service for the crew. An estimating tool for the bids. Double entry, broken syncs, four invoices.
One platform
Everything you need to run the job.
A real general ledger
Native double-entry accounting — P&L, balance sheet, AP 3-way match, AR aging, WIP. Not a QuickBooks sync. Export to QuickBooks anytime.
Certified payroll, built in
CA overtime, labor burden, WH-347, and one-click DIR eCPR XML filing. No separate payroll service.
AI bidding from a planset
Upload the plans; get a confidence-tagged takeoff and a clean bid PDF. You verify before it goes out.
Bid → budget → actuals
A won bid becomes the budget in one click; job-cost variance is live — because it’s all one ledger.
Critical-path scheduling
A real Gantt with dependencies and the critical path highlighted.
Selections & allowances
Track every fixture against its allowance; overages roll to a billable change order.
No-login client & sub portals
Clients approve change orders; subs submit invoices and COIs — from a link, no account.
An AI copilot over your books
“Which jobs are over budget? How much AR is past 60 days?” — answered from your live data.
Why Bullwork
Built by a California contractor — because nothing else did all of it.
Every other tool made us bolt a PM app onto QuickBooks onto a payroll service. So we built the one we wanted: bid to books, certified payroll and all, on a single ledger that balances to the cent.
No enterprise bloat. No “call sales for a price.” Just the straightforward tool — built for contractors, not computers.
How it stacks up.
The others are good at part of the job. Bullwork runs all of it — with the books and the bidding inside.

Questions, answered.
Do I have to give up QuickBooks?＋
No — Bullwork has a real general ledger built in, so you don’t need QuickBooks at all. If your CPA still wants it, export a QuickBooks file anytime.
Is it really all in one tool?＋
Yes — project management, native accounting, certified payroll, AI bidding, and client/sub portals are one platform, not a PM app bolted onto QuickBooks and a payroll service.
Does it handle California certified payroll?＋
Yes — run payroll natively with CA overtime and labor burden, generate the WH-347, and file public works with one-click DIR eCPR XML.
How does the AI bidding work?＋
Upload the planset. The engine builds a quantity takeoff with a confidence score on every line, prices it, and produces a clean bid PDF. You verify on screen before it goes out.
What does it cost?＋
One flat plan with unlimited users — no per-seat math. Your first month is free, no credit card required.
How fast can we start?＋
Days, not months — we set you up personally. It installs on any phone as an app, so your crew uses it in the field.
If you can send an email, you can run a job on it.
See it run your numbers — bid to books — on your own jobs. Your first month is free.
