EVIDENCE
Your team approves before anything ships.
Every output points at its source. Every scope item, every variation, every buying suggestion has an evidence link back to the drawing, the note, or the invoice that produced it.
Every output is reviewable. Open questions, confidence levels, and assumptions are visible on every artefact — your estimator approves before anything ships.
Every decision leaves a trail. Change logs, sign-offs, and revision impacts are timestamped and traceable.

A day off every quote. An audit trail for every decision.
Before
With
Before
Three hours copying drawings into a spreadsheet.
With
An hour reviewing a generated scope with evidence links.
Before
Rev C lands. No one knows what changed from Rev B.
With
A summary of every change between revisions, with cost implication notes.
Before
Variations turn into disputes because WhatsApp isn't a record.
With
A timestamped decision log with source-drawing references.
Before
Supplier price assumed in the estimate. Actual price found out later.
With
Procurement memory built from real invoices, suggesting the right number first.
None of this replaces your estimator. It takes the boring half of the job off their plate.
WHO MADE THIS
Built by two practising professionals in residential construction.
"BuildGuider is built by two operators who priced jobs, ran sites, and got tired of doing the boring half of estimating at 10pm on a Sunday. We're still in the industry. We test BuildGuider on our own projects before any customer sees it."
"This is the tool we wished existed when we were the bottleneck." — [Founder name, role]

A London residential builder running BuildGuider on live projects since 2026.
HOW WE START
Pilot first. Pricing second.
We don't quote into the dark. The first conversation is a pilot — thirty minutes, with a real drawing pack from one of your live projects. You see what BuildGuider reads, what it flags, and what it produces. Pricing comes after we both know it'll work for your business.
Start the pilotFOR HOMEOWNERS
Your clients see the same project. In plain English.
The homeowner layer means your clients understand what's happening, what's coming, and what was agreed. Fewer 9pm WhatsApps. Fewer disputes. Better referrals.
START SMALL
See it on your drawings.
Send us a real drawing pack from a real project. We'll show you what BuildGuider reads, what it flags, and what it produces — before any commercial conversation. Thirty minutes.
