The back office for construction contractors. Win more work, catch what costs you.
It reads your bid, the GC's contract, vendor quotes, and invoices, then marks every scope, price, and exclusion change on the exact line, before you sign or award.
Scope added back into the contract.

CAUGHT
6 changes caught between bid and contract. Each one before you sign.
One workbench for the whole back office.
It starts with contract and buyout review, then keeps going: RFIs, estimating, vendor pricing, submittals, change orders. Click any box to see it.
The old way vs. FlowManual.
You still read every page. The difference is what happens to the line you would have missed.
The GC adds scope back into a 512-page contract. You find it after you sign, and a single missed addition runs $5K to $10K.
A vendor's invoice drifts off the locked buyout mid-job. The original quote is in a file cabinet somewhere, and incidents can reach $100K and up.
The one line that decides who owns the cost is on page 318 of 512. By the time anyone finds it, the work has already started.
Scope added back into the contract is flagged on the exact line, ranked by dollar impact, before you sign.
Every invoice is compared to its buyout in seconds, so a price that moved is caught while you can still do something about it.
The costly line surfaces on the first read with a margin label and a clause reference. Nothing hides on page 318.
Your contracts never leave the building.
Your pricing, vendor relationships, and margins stay on hardware you control, not someone else's cloud.
Files never leave your server
The entire app runs in a container on your own hardware. No contract, bid, or invoice is ever transmitted to FlowManual or any cloud.
The model only ever sees text
Only extracted plain text is sent to the model, never your original file, under Anthropic's zero-retention policy. Or run a local model so even the text stays on your network.
We have zero access
No telemetry, no phone-home, no remote access in the container. After install, your IT controls everything. We cannot see your data even if subpoenaed.

Win more work. Stop signing scope you didn't bid.
