TenderIn — Matches UK public tenders to what a supplier can prove, and shows what's missing.
Tender finding and bid writing for UK suppliers. It reads every notice on the UK's public procurement feeds each morning, matches it to what a business can prove, shows exactly what's missing, and drafts compliant bids from the supplier's own evidence.
The problem
Suppliers drown in tender alerts, find out too late that a mandatory certificate is missing, and spend days writing bids that claim more than they can evidence.
What we built
Daily matching against Find a Tender and Contracts Finder, a readiness check that never lets a high match score hide a missing requirement, NHS-specific checklists, and drafts that only say what the supplier can prove.
What it does today
In private beta: every morning's notices matched to the supplier's evidence, the missing requirements listed, and bid drafts that only claim what can be proved.
— Under the bonnet
What makes a product like this hard to build
- 01
Reading every notice, every morning
Find a Tender and Contracts Finder publish many notices a day in inconsistent formats. Ingesting, de-duplicating and structuring them on schedule is the foundation.
- 02
Matching to what a supplier can prove
Matching isn't keyword search. Each notice's requirements are compared with the supplier's actual evidence, certificates and past projects.
- 03
Never hiding a blocker
A high match score must never hide a missing mandatory certificate, so mandatory requirements are checked separately and shown first.
- 04
Drafts that only claim what's true
Bid drafts are written from the supplier's own evidence, and anything that can't be backed up is left out rather than invented.

Sized from the codebase we built: 32k lines of production code, 22k lines of tests, 50 database tables.
A product like TenderIn is a bespoke build, not a template: most of the cost is in the hard parts above, plus testing against real data before anyone relies on it. Where your version lands in the range depends on the factors listed here. You get a fixed price once scope is agreed — usually after a short discovery sprint. Hosting and AI model usage are billed at cost on your own accounts.
