Tender writing software for UK public-sector bids.

Tender writing software helps you write responses to public-sector tenders (ITTs/RFPs) — extracting the questions, drafting answers from your reusable content, checking word limits and mandatory requirements, and managing deadlines. BidWriter is tender writing software built for UK procurement: it turns the blank-page work of answering each tender question into a fast, structured, compliant process.

A tender writer is a person or agency you pay to write the tender; tender writing software is the tool that lets your own team do it faster and more consistently. BidWriter drafts each answer from your content library in seconds, surfaces your best past responses, and flags compliance issues — for a fraction of the cost of outsourcing. Most teams use the software to do the heavy lifting and keep the strategy and final sign-off in-house.

It should: extract questions, word limits and weightings from the ITT (PDF/Word/Excel); draft answers from your reusable content; check mandatory questions and word limits; score draft quality; track deadlines across multiple bids; and ideally surface matching live opportunities. BidWriter does all of this and is built around UK frameworks (Procurement Act 2023, Crown Commercial Service, NHS SBS, Find a Tender).

Yes — BidWriter has a free plan with AI credits so you can write a real tender answer with no card. Paid plans add more credits, seats and unlimited drafting from £49/month.

They overlap heavily — "tender writing" and "bid writing" describe the same task in UK public-sector procurement. BidWriter is both. If you are comparing tools, see our ranked bid writing software page; if you specifically need to respond to RFPs/ITTs, see tender response software.
