A construction estimating platform that turns days of spreadsheet work into a single guided flow.
Builder Expert serves UK builders working on extensions, refurbishments, and full-scale developments. Before CodLight, every estimate began with a blank spreadsheet, manual supplier lookups, and hand-built bills of quantities — a process that often ate two to three days per quote and left margin on the table whenever supplier pricing moved mid-project.
We designed and shipped the end-to-end estimating platform: a guided estimate flow, a live pricing engine that pulls current material rates from supplier feeds, instant digital BoQ generation with one-click PDF and CSV export, and an on-site mobile companion for surveys and as-built updates. The system was built on Next.js with a typed Node backend and PostgreSQL, deployed on AWS with full audit trails so historical estimates remain reproducible.
“CodLight didn't just build the software — they understood how a UK build team actually works. Our quotes go out the same day now, and our win-rate has noticeably climbed.”
