Colour-coded like the boards on site. Every account opens with a finished sample project in all four.
Every step works off the BoQ you priced, so nothing gets re-keyed and nothing slips between office and site.
01 · ESTIMATE
From manufacturer system to costed BoQ.
Pick from 3,054 manufacturer-verified British Gypsum, Knauf, Siniat and Fermacell systems, filtered by fire, acoustic and height. The calculator lists every component and saves it into the project BoQ. Tenders are tracked until they're won.
02 · BUY
Every merchant's price on your lines. Call-offs from the BoQ.
Upload price lists as they come. FixMargin matches them to your BoQ lines, compares per sheet, metre and box, shows what's missing and works out the best mix. Call-offs go out from the BoQ, and the planner suggests them from lead times.
03 · BUILD
Programme, materials and site, in the same file.
A Gantt planner with linked tasks. Material readiness shows what's on site before the gang arrives. Deliveries are booked in against the order. Site managers file the daily report from the phone, with photos and a signature, saved as a PDF.
04 · GET PAID
Check before you pay. Claim everything you did.
Every invoice is matched against the order and the delivery note. A mismatch becomes a dispute with the evidence attached, not a payment. Variations are logged when the work happens, with the site evidence attached. Priced vs bought vs claimed is a live number per project.
The office and the site on the same job.
Four roles with clear permissions and an audit trail. Operatives never see commercial figures.
Directors, QS, estimators, buyers
BoQ, prices, call-offs, invoices, variations and margin.
Site managers
Programme, deliveries, materials, team and site reports.
Supervisors
The projects they're on, progress and daily reports.
The gang
Their tasks and site updates from the phone.
