What is BidWriter?

BidWriter is a cloud-based bid management and AI writing platform built specifically for organisations competing for UK public sector contracts. It is developed and operated by eSourcing Data, the company behind WinAContract — the UK's leading procurement intelligence platform.

The platform combines four core capabilities: AI-assisted bid writing, tender pipeline management, framework and DPS tracking, and a bid library for reusing evidence and past responses. BidWriter is designed for procurement teams of all sizes — from sole traders bidding on Contracts Finder to enterprise organisations managing large portfolios across G-Cloud, Crown Commercial Service frameworks, and Dynamic Purchasing Systems.

BidWriter's AI Bid Writer generates structured draft responses to tender questions based on the organisation's stored evidence, previous winning answers, and the specific word limits, marks allocation, and requirements of each opportunity. Responses are generated using large language model AI and reviewed by the bid writer before submission. As dedicated AI tender software for the UK public sector, it also works as RFP software for commercial and grant proposals.

How BidWriter works

A structured four-step process from opportunity to outcome — designed around how professional bid teams actually work.

Find

Search live opportunities from Find a Tender, Contracts Finder, and WinAContract's procurement intelligence database, filtered to your sectors and CPV codes.

Qualify

Run each opportunity through the Bid/No Bid scoring matrix. Assess strategic fit, win probability, and resource requirements before committing to write.

Write

Use the AI Bid Writer to generate structured draft responses. Assign questions to team members, track word counts and marks, and iterate until submission-ready.

Track

Record outcomes — won, lost, or withdrawn. Analyse win rate trends, revenue pipeline, and team performance to continuously improve future bids.

Built for UK public sector procurement

BidWriter supports all major UK government procurement frameworks, portals, and Dynamic Purchasing Systems — including Crown Commercial Service, G-Cloud, Digital Outcomes & Specialists, and Find a Tender Service.

Frequently asked questions

Everything you need to know about BidWriter and AI-assisted bid writing for UK public sector procurement.

What is BidWriter?

BidWriter is an AI-powered bid writing and management platform built specifically for UK public sector procurement teams. It combines bid pipeline tracking, AI-assisted tender writing, framework and DPS management, and a bid library into a single cloud-based workspace.

How does BidWriter use AI for bid writing?

BidWriter uses large language model AI to draft responses to tender questions based on your organisation's bid library, previous winning responses, and the specific requirements of each opportunity. The AI Writer generates structured draft answers that your team can review and refine, typically reducing bid writing time by up to 8.7× compared to writing from scratch.

Which UK procurement frameworks does BidWriter support?

BidWriter supports all major UK public sector procurement frameworks including G-Cloud, the Digital Outcomes and Specialists (DOS/DDAT) framework, Crown Commercial Service (CCS) frameworks, Dynamic Purchasing Systems (DPS), and opportunities published on Find a Tender Service (FTS) and Contracts Finder.

Is BidWriter suitable for small businesses bidding for government contracts?

Yes. BidWriter offers a free plan with 3 AI credits per month and paid plans starting at £49/month, making it accessible to SMEs and sole traders. The platform helps smaller organisations compete more effectively against larger suppliers by streamlining the bid writing process and ensuring compliance with procurement requirements.

How does BidWriter help with bid/no-bid decisions?

BidWriter includes a Bid/No Bid scoring tool that evaluates each opportunity against configurable criteria including strategic fit, win probability, resource requirements, and contract value. This helps procurement teams make evidence-based decisions on which tenders to pursue, rather than chasing every opportunity.

Can multiple team members collaborate on bids in BidWriter?

Yes. BidWriter supports multi-user collaboration with role-based access. Administrators can assign individual tender questions to specific team members, track progress across all questions in real time, and manage deadlines centrally. Team seats are available from the Starter plan upwards, with additional seats available as a £18/month add-on.

What is the difference between BidWriter plans?

BidWriter offers five plans: Free (1 user, 3 AI credits/month), Starter at £49/month (1 user, ~6 tenders/month), Professional at £149/month (1 seat, ~25 tenders/month), Business at £279/month (3 seats, ~75 tenders/month), and Enterprise at £799/month (unlimited users and credits). Annual billing saves 20%. Additional seats can be added to any paid plan at £49/seat/month.

How does BidWriter track government framework expiry dates?

BidWriter's Framework Manager lets you add and monitor all your active framework agreements and DPS registrations, including expiry dates and renewal windows. The platform sends automatic alerts ahead of expiry so you never miss a re-qualification deadline or renewal opportunity.

Does BidWriter integrate with Find a Tender or Contracts Finder?

BidWriter connects to WinAContract's procurement intelligence data, which aggregates opportunities from Find a Tender Service, Contracts Finder, and other UK public sector procurement portals. This allows you to find and import relevant opportunities directly into your pipeline without manually searching multiple sources.

Is BidWriter GDPR compliant?

Yes. BidWriter is built and hosted in the UK, with all data stored in UK data centres. The platform is GDPR compliant, and eSourcing Data, the company behind WinAContract and BidWriter, operates under UK data protection law.
