Proposal software for UK tenders, RFPs and bids.

Proposal software helps teams create, manage and submit proposals — drafting content from a reusable library, keeping answers consistent, checking requirements, and tracking deadlines. In the UK public sector, a "proposal" usually means a tender or RFP response, so the most relevant proposal software is built around procurement rules. BidWriter is proposal software for UK public-sector bids: it drafts each answer from your content library and checks it against the buyer’s requirements.

They overlap. "Proposal software" is the broader term (it can include sales and commercial proposals); "RFP software" specifically helps you respond to Requests for Proposal. For UK public-sector RFPs/ITTs, the same tool serves both — BidWriter handles tender/RFP responses and the proposal content behind them. See our RFP software page for the response-focused view.

It should let you reuse approved content (case studies, methodology, social value), draft answers fast, enforce word limits and mandatory questions, collaborate across a team, and track deadlines. BidWriter does all of this and is built around UK frameworks (Procurement Act 2023, Crown Commercial Service, NHS SBS, Find a Tender) rather than being a generic US proposal tool.

Yes — BidWriter offers a free plan with AI credits so you can draft real proposal content with no card. Paid plans add more credits, seats and unlimited drafting from £49/month.

For UK public-sector tenders and RFPs, BidWriter is purpose-built and includes a live UK opportunity feed plus AI drafting and a content library, with a free plan.
