Every certified claim holds back its 5%. siteMargin keeps the running total, so the release isn't a surprise on either side of the table.
Raise a PO against a line item and its budget already knows the money's spoken for.
Money out is 21 points ahead of work done on this line. That's the one to walk before the next claim goes in.
The number that gives an overrun away isn’t the budget — it’s the gap between money spent and work actually done. Proper cost-control software watches that gap, but it is built for firms with a full-time QS and a budget to match. For a two-to-ten person outfit it is overkill, so the job ends up in a spreadsheet nobody updates until it matters.
That is not a discipline problem. It is a structural one: the only person you can trust with the whole file is the one person with no time to open it — and the people with time are the ones you can’t show your margins to.
Built around real job-site roles, not hypothetical ones.
Budget vs actual that updates itself, not a spreadsheet you rebuild every Friday.
Clean POs, visible payment and retention status.
On budget, on track — not a platform built for a GC.
You hold the retention and pay for the variations. The same numbers, read from your side of the table.
For developers →Six tools, six colours — so you always know which one you're in.
Built in Cape Town for South African contractors — JBCC-aware, rand-native, retention held the way your contracts hold it.
Log spend in under a minute — a tool nobody updates is worse than none.
No variance formulas. No QS training. Just numbers you can read.
Free on your first job. Paid plans for outfits running two to ten, not enterprises.
No. siteMargin uses plain language — "spending ahead of progress," not a spreadsheet of variance formulas you have to interpret yourself.
Yes. Export your current spreadsheet to CSV and import it in one go — no retyping line items from scratch.
It's yours. Your project data stays in your account, and you can export a PDF of any project at any time.
