A €12M bid still gets priced by phone, email and Excel.

Contractors run on dozens of supplier quotes per tender, retyped PDFs and paper site books. Every tender and every site starts from scratch, and the knowledge leaves with the people.

Tender

Supplier quotes chased by hand, priced in the sixth version of the same BOQ.

Site

The site diary gets written on Friday, from memory.

Billing

Measurement book and progress bills rebuilt from notes at the end of the month.

Memory

Last year's real prices sit in someone's inbox, not in the next bid.

The system

One system, from tender to final invoice.

AI does the chasing, reading and retyping. People make the decisions.

Phase 1Win the work

Tenders and supplier quotes

  • Reads the BOQSplits the tender into supplier packages automatically.
  • Sends and chases requestsAI emails suppliers and follows up until quotes arrive.
  • Levels the offersReads PDF, scanned and Excel quotes and compares them line by line.
  • Prices the bidWith company memory of what every item really cost before.
Phase 2Run the site

Site, diary and billing

  • Work planningCrews, machines and norms organised per site.
  • Site diaryKept daily from the field, not rebuilt on Friday.
  • Measurement bookQuantities recorded as work is done.
  • Progress billing and e-invoicesBills generated from the measurement book.

The loop closes. Real costs from the site flow back into norms and into the next bid, so every tender is priced on what the company actually spent.
