£0bn
UK annual public sector spend. What's limiting you isn't what you can deliver — it's how you prove it on the page.
The problem

Three reasons UK SMEs lose tenders they should have won.

01
No case study library
Project evidence is scattered across old submissions, emails and spreadsheets. Every new ITT means hunting for the same material — or drafting without it and hoping the evaluator doesn't notice the generic answers.
"We had the case studies. We just couldn't pull them together before the deadline."
02
Writing for the response, not the evaluator
Most SMEs write tenders that describe what they do. Public sector evaluators score what you will deliver, how it will be governed and what evidence proves you've done it before. Generic writing scores Adequate at best.
"Our technical approach was strong. The panel just couldn't find the evidence to support it."
03
Starting from scratch every time
Without a reusable bid library — case studies, methodologies, social value evidence, Carbon Reduction Plan content — every ITT costs the same. No compounding, no learning loop. The win rate stays flat.
"We submitted ten tenders last year. Won three. The process wore the team out more than the losses did."
The proven process

9 stages. From AI setup to a stronger library after every bid.

Your end-to-end journey to winning public sector bids with AI — built on proven procurement expertise.

01
Stage 01
AI workspace setup
Choose ChatGPT Plus or Claude Pro. Create your dedicated Bid Project and install the Master System Prompt. Your AI becomes a guided bid expert — inside the account you already have — from the first session.
→ Professional bid AI ready in under an hour
02
Stage 02
Evidence library build
Upload your past submissions, case studies and company documents. Run extraction prompts to build a graded evidence vault — tagged by theme, sector and evaluation factor. Grade A content ready to draw from on every ITT.
→ Evidence library that compounds with every bid
03
Stage 03
Responsible AI use
Understand how to use AI responsibly in public sector bidding. Verify everything. Never invent case study outcomes, KPIs or accreditations. Evidence discipline is built into every prompt from day one.
→ Safe, compliant and evidence-led from the start
04
Stage 04
ITT decode
Upload the ITT, specification and all clarifications. Run the full structured ITT decode — MEAT weightings, evaluation criteria, social value requirements, deadlines and compliance risks identified before a word is drafted.
→ Evaluator-focused plan before drafting begins
05
Stage 05
Draft responses
Match evidence to each question. Generate evidence-backed first drafts per evaluation criterion. Flag evidence gaps. Run the first-pass evaluator critique (score out of 50) on every answer before human review begins.
→ Evidence-backed first drafts ready for review
06
Stage 06
Human quality review
The Bid Lead reads every draft. Verify case study outcomes from delivery records. Ensure MEAT criteria are fully addressed. Add specific metrics, named contacts and delivery dates. Issue the revision brief. Apply AI revision per criterion.
→ Verified, evaluator-credible responses
07
Stage 07
Finalise & pre-submit
Cross-answer consistency check. Social value and carbon alignment. Word count and page limit control. Mock evaluator scoring session. Portal submission checklist — every control applied before the Contracts Finder deadline.
→ Answers that compete for top MEAT scores
08
Stage 08
Submit & update library
Submit via the buyer portal — two hours before the deadline. Save confirmation reference. Run post-submission debrief. Extract Grade A content to the library. Update evidence gap register. Log outcome and pattern intelligence.
→ Stronger library after every submission
09
Stage 09
Prompts that deliver
Use all 175 UK prompts for every stage — Decode, Plan, Draft, Evaluator Critique, Tighten. Run the scoring critique before submitting. Save and adapt prompts for your target buyers. Every prompt built for PPN 002, MEAT and Contracts Finder.
→ High-scoring answers using the right prompts, fast

Structured process
What makes it different

What if every tender was built the way evaluators actually score?

Build My Bid Manager is not an AI writing tool. It is a complete UK bid operating system — one that builds a reusable library from your own evidence, runs every draft through an evaluator critique, and gets stronger after every tender.

Start free — first tender free →
  • 01
    Company brain & case study engine
    Verified case studies, evidence vault and company profile — built from your own documents, never invented. Every answer draws from real proof, not generic language.
  • 02
    Evaluator scoring at every draft
    Every answer scored out of 50 against the evaluation criteria before you accept it. Answers below 35/50 must be rewritten. You see the panel's view before they do.
  • 03
    Social value & carbon built in
    PPN 002-aligned social value library, Carbon Reduction Plan evidence and ESG commitment checks — embedded in the system, not bolted on afterwards.
  • 04
    No invented claims — ever
    Every prompt instructs the AI to write [EVIDENCE NEEDED] when evidence is missing. Never invent a case study outcome, KPI or accreditation. You cannot submit what you cannot support.
  • 05
    Post-bid learning loop
    After every submission: extract Grade A content, update the evidence vault, log the outcome. Each bid makes the next one faster, stronger and more likely to win.
Your own AI, either way

It runs inside the account you already have.

ChatGPT Plus is £20/month. Claude Pro is £20/month. You probably already have one. Both the app and the download run inside your own account — your key, your bill, your data. No API keys, no developer setup, no third-party platform, no separate login.

The compounding advantage

The library gets stronger after every bid.

  • First tender builds the Company Brain, Evidence Vault and Case Study Library.
  • Second tender draws from the library — drafting is faster, evidence is stronger.
  • Third tender adds new case studies, closes evidence gaps, scores more consistently.
  • Post-bid learning loop extracts Grade A content after every submission — no exceptions.
  • After six months, your library is a competitive asset built from six tenders — not six consultants.
BID LIBRARY SUBMIT ITT DRAFT WITH EVALUATOR LENS EXTRACT & LEARN STRONGER LIBRARY
"We can't guarantee you'll win. We can guarantee your next tender will be built on verified evidence, scored from the evaluator's perspective, and structured to compete at the highest level."

Public sector procurement is competitive. The contract goes to the strongest submission on the day — not necessarily the best-performing supplier. What we give you is every possible advantage before the evaluator opens your response. The rest is yours to win.

How the two products work together

Build My Bid Manager (£600) gives you the complete AI bid operating system — ITT analysis, evidence library, 175 prompts, evaluator scoring on every answer. Social Value Advantage Pack (£600) gives you a complete PPN 002 Social Value Pack built from your own evidence — statement, policy, 8 themed sections and MAC mapping. Together they cover the full tender response. Social value typically scores 10–20% of total marks — use both to compete at every level.

Why trust this
"This system was built by people who sat on the other side of the evaluation table — not by AI developers who have never read an ITT."
bidpiston by ebida · ex-Public Sector Procurement Directors
  • Built by ex-procurement directors
    The people who designed this system have sat on evaluation panels, managed MEAT scoring and awarded public sector contracts. They know what wins because they decided who won.
  • Social value and carbon built in
    PPN 002 social value alignment, Carbon Reduction Plan evidence and ESG commitment checks are embedded in the system — not afterthoughts bolted on at submission.
  • No invented claims — ever
    Every prompt instructs the AI to write [EVIDENCE NEEDED] when evidence is missing. Never invent a case study outcome, KPI or accreditation. You cannot submit what you cannot support.
  • Two ways in — no lock-in either way
    Subscribe to the app and cancel any time, or buy the download once and own it forever — no fee to us beyond your own ~£20/mo ChatGPT or Claude. Whichever you choose, the library you build is yours to keep and compound.
Who this is built for

Built for UK SMEs who know they can deliver.

If your capability is real but your tenders don't prove it at evaluation level, this system is built for you.

Established SMEs bidding on ITTs
You are actively bidding via Contracts Finder or Find a Tender but your win rate is flat. You know your delivery record is strong — you just can't pull the evidence together fast enough, or structure it the way an evaluator scores it.
SMEs new to public sector
You have real delivery experience in the private sector and want to break into public contracts. You understand the work — you need a system that teaches you how public sector buyers evaluate, what MEAT scoring means and how to write for it.
Firms scaling their bid volume
You are winning some contracts but every bid still costs the same time. Without a reusable evidence library and methodology, you can't increase bid volume without burning out. This system compounds — each tender makes the next one faster and stronger.

This is not for firms with no prior delivery experience, businesses with no case studies or evidence to work from, or organisations looking for a generic writing tool. Build My Bid Manager requires real evidence — it turns that evidence into a competitive, evaluator-ready library. The evidence has to be yours.

Frequently asked questions

Everything you need to know before you buy.

No. The system is designed to be installed by a non-technical user in under an hour. Open your existing ChatGPT or Claude account, create a project, paste the Master Installation Prompt and follow the guided setup. The AI walks you through every step. If you can copy and paste, you can install this.
You can sign up for either at openai.com or claude.ai — both are around £20/month with no long-term commitment. If you buy the download, that AI subscription is your only ongoing cost. If you subscribe to the app, you add the bidpiston monthly fee on top and it runs the whole process for you. Most UK SMEs bidding on tenders already have ChatGPT or Claude.
The system is built around the public procurement framework that governs the vast majority of UK public sector buying — MEAT scoring, PPN 002 social value, Carbon Reduction Plans and Contracts Finder/Find a Tender workflow. The 175 prompts include context modes that can be adapted to your specific buyers, sectors and frameworks.
Using ChatGPT directly gives you a general-purpose AI with no public sector bid knowledge, no evaluation criteria awareness and no evidence discipline. Build My Bid Manager gives you 175 prompts engineered specifically for UK public sector bidding — plus a Master System Prompt that transforms your AI into a bid specialist, an evidence library that grows with every tender, and a governed 9-stage process built by ex-procurement directors who have actually awarded contracts.
The system is designed to work with whatever evidence you have. Stage 02 explicitly identifies evidence gaps and builds a register to close them over time. If your library is thin, the system flags this honestly using [EVIDENCE NEEDED] markers — rather than inventing case study outcomes that could undermine your tender or be challenged by the buyer.
Yes. The download pack is yours to use within your organisation. The Interactive Guide and Prompt Library can be used by multiple team members. The AI project itself lives in whichever ChatGPT or Claude account your team uses for bids — so the evidence vault and library all live in one shared workspace that compounds with every submission.
Yes. The £600 + VAT founding member price reflects early access before the next release update. When the next version launches, the price moves to £997 + VAT. Founding members pay once, own the system permanently and receive any updates as part of that original purchase.
The people who designed this system have personally sat on MEAT evaluation panels, managed procurement processes and made contract award decisions in the UK public sector. They know what earns a top score because they assigned those scores. This is not a system designed by AI developers or writers who have observed procurement from the outside — it is built on first-hand evaluation experience.

Your next tender starts here.

Let the app run it for you, or download the tools and run it yourself. Either way, a bid system that gets stronger after every tender.
