Know where every job actually sits.
Your margin, claims and variations, worked out live from your jobs. Ask it anything.
Builders don't go broke at the start of a job. They go broke at the end.
- Quotes priced at 9pm off a pile of PDFs.
- Variations agreed on site. Never written down.
- Claims out late, or ahead of the work.
- Friday gone chasing timesheets.
None of it's a mystery. It's just scattered across four tools and your head.

Send it in. BuilderOS sorts it. You sign off.
Send it in.
Forward the email or drop in the PDF. Your company gets its own address.
BuilderOS sorts it.
It reads every line, finds the job and the stage, and splits a stack of invoices into separate ones.
You sign off.
Check it and approve. Nothing is filed until you say so.
From the first quote to the last claim.
Price from the quotes you already have
Drop in supplier and subbie quotes. The lines land in your price, stage by stage.
Proposals that win the job
Three looks, your words, your logo. The client reads it and accepts online.
Claims out the same day
A proper payment claim and tax invoice, as a PDF and a link your client opens on their phone.
Variations signed before the work
Photos and quotes attached. The client approves on their phone before you start.
Timesheets without the chase
The crew log hours on their phone. Missing ones get chased. You approve the week and send payroll a clean file.
Every dollar against the job
Quoted against spent on every line, so you see the overrun while you can still do something about it.
Fixed price or charge-up. It runs both.
Ask it like you'd ask your office manager.
It knows every job, every hour and every dollar. Type it or just say it, and get a straight answer.
It comes from your jobs, never made up. If it doesn't know, it says so.
Quotes, timesheets, invoices, claims and emails in one answer. No digging through five screens.
Your foreman gets his crew's hours. Your margins stay yours.
Claim for work done, not stages guessed.
Stage claims get you ahead of the work. By the end the money's spent, and the last stretch is on you.
BuilderOS builds each claim from work actually done. You stay ahead by your margin and deposit, never more. The money to finish is always there, and your client can see exactly what they're paying for.

I've done the sums at 2am too.
Is this job still making money? Did that variation get signed? Will the claim land before the wages go out? I ran a building company, and I carried those questions home every night.
BuilderOS keeps the answers ready, so you don't have to keep them in your head.
