Why QuantiFlow
Built around how QS work actually gets done
Save hours on takeoffs
What used to take a full day now takes minutes. Upload a PDF drawing set and let the AI extract every dimension, material, and quantity — no manual measurement required.
Eliminate double-counting
QuantiFlow's cross-referencing engine tracks every item across drawing revisions and flags discrepancies before they become pricing errors — or worse, contractual disputes.
Live material pricing
Stop using last quarter's rates. QuantiFlow connects to UK supplier databases so your BoQ always reflects current market prices — not stale spreadsheet data from six months ago.
Features
Everything your practice needs, in one platform.
Extract quantities straight from your drawings.
Upload your PDF drawings and QuantiFlow reads the geometry, annotations, and schedules automatically. No manual scaling, no digitiser — just measured quantities, referenced back to the drawing.
Client-ready Bills of Quantities in seconds.
Produce fully formatted Bills of Quantities in NRM2 structure, ready for issue. Export to PDF or Excel with a single click. Every item described to standard, every measurement traceable.

AI catches double-counting before it costs you.
QuantiFlow checks all uploaded drawings against each other, identifying overlapping measurement zones and conflicting annotations. Every conflict flagged, every saving logged in the audit trail.
Every item priced against UK market rates.
Each line item in your BoQ is automatically priced against our maintained UK materials database. Rates updated regularly. No more manual rate lookups, no more outdated price books.

FAQ
Common questions.
Yes. All data is encrypted in transit (TLS 1.3) and at rest (AES-256), and we never share your drawings or project data with third parties. You can export or delete your data at any time, in line with UK GDPR.
Yes. Cancel your subscription at any time with no penalties or exit fees. Your data remains accessible for 30 days after cancellation, giving you time to export any documents you need.
No. The Business plan includes multi-role access so your whole project team — quantity surveyor, builder, and architect — can collaborate under one subscription. Each role has appropriate access controls managed from the admin dashboard.
QuantiFlow works with PDF drawings — the format most UK practices issue and receive — with no limit on the number of drawings per project. Support for additional CAD formats is in development.
Every measurement is reviewable and editable before your BoQ is finalised, and every item links back to its source drawing location — nothing is a black box. Accuracy depends on drawing quality and annotation clarity; in beta testing on real UK residential projects, takeoffs have needed only minimal manual adjustment.
