Using AI to write a simple tender or RFP response when a government body or corporate client asks you to bid for work

The U.S. federal government awards over $650 billion in contracts annually, with a statutory 23% goal for small businesses — yet most small businesses never bid because the paperwork alone kills the attempt before it starts. This post walks you through a repeatable, step-by-step process for using AI to write a tender response, section by section, without hiring a specialist bid writer. Done correctly, this approach can cut the time cost of a first-draft response from 15–20 hours down to 4–6 hours, which is the difference between bidding and not bidding.

What You Need Before You Start

ChatGPT{:target="_blank"} — OpenAI's general-purpose AI model, capable of drafting structured long-form content from pasted inputs. For tender writing, the GPT-4o model handles tone, structure, and reformatting reliably. ChatGPT pricing{:target="_blank"}: the free tier works for text-only drafting; file upload (to feed in a PDF of the RFP) requires ChatGPT Plus at $20/month as of early 2026. Claude{:target="_blank"} by Anthropic is a strong alternative — Claude 3.7 Sonnet (released February 2025) handles long documents particularly well. Claude pricing{:target="_blank"}: free tier available; Claude Pro at $20/month as of early 2026 for file uploads.

Time required: 1–2 hours to gather your inputs and build the source document (see the next section); 3–4 hours to work through each tender section using the step sequence below. Plan for one additional hour for compliance checking and final editing.

Skill level: No technical background required. You need to be able to copy and paste text, follow a structured prompt sequence, and critically read AI-generated output for factual errors. That last skill is non-negotiable — more on why below.

How to Write a Tender Response: Gather Your Inputs First

This is the step most small businesses skip, and it's why their AI output comes back generic and unusable. The quality of the output is entirely dependent on what you feed in. An AI tool cannot access your internal business data unless you paste it in — it will fill gaps with plausible-sounding content it invents, which is a serious problem in a formal bid document.

Before opening any AI tool, assemble the following into a single working document:

1. Paste the full RFP or tender document text — copy from the PDF or portal directly. If the document is behind a login (as it often is on portals like SAM.gov{:target="_blank"} in the US, Contracts Finder{:target="_blank"} or Find a Tender{:target="_blank"} in the UK, AusTender{:target="_blank"} in Australia, GETS{:target="_blank"} in New Zealand, or MERX{:target="_blank"} in Canada), copy the scope of works text manually.

2. Write a 200–300 word plain-English summary of your company — what you do, how long you've been operating, your team size, and any relevant certifications or registrations.

3. List 2–3 relevant past projects — for each, include the client name (or a descriptor like "a regional council in [state]"), the scope of work, the dollar value if you can disclose it, the timeline, and one measurable outcome (e.g., "delivered 3 weeks ahead of schedule," "reduced client processing time by 40%").

4. Note the evaluation criteria and their weightings — most government tenders use a weighted scoring matrix (a common split is 60% technical merit, 40% price). If technical merit outweighs price, you should spend proportionally more effort on the methodology and experience sections. Identifying this upfront is one of the highest-leverage decisions in bid preparation.

5. Pull any compliance credentials — insurance certificates, business registration numbers (ABN, company number, EIN), relevant licenses. These are pass/fail requirements that AI cannot draft for you and that evaluators check first.

How to Draft Your Small Business Tender Response Section by Section

A typical government RFP requires responses across six to eight sections: company background, relevant experience, methodology or approach, key personnel, pricing schedule, and compliance declarations. Work through them in this order using the prompt workflow below.

1. Open a new chat in ChatGPT or Claude. Paste the full RFP text first, followed by your assembled source document from the previous section.

2. Run the requirements summary step. Use this prompt:

You are a professional bid writer helping a small business respond to the following government tender. Read the full RFP text I've pasted above. Summarise the key requirements in a numbered list, identify the evaluation criteria and their weightings if stated, and flag any sections marked as mandatory compliance (pass/fail). Do not draft any response content yet.

You should get back a clean requirements list. Check it against the original RFP — if anything is missing or misread, correct it in your next message before proceeding.

3. Draft the Company Background section. Use:

Using only the company information I provided in my source document, draft the Company Background section for this tender response. Use formal third-person language (e.g., "ABC Services is a..." not "We are a..."). Keep it under 300 words unless the RFP specifies otherwise. Do not invent any facts, dates, or credentials not present in my source document.

Third-person institutional tone is the most common formatting mistake small businesses make — procurement evaluators notice casual language, and it signals inexperience.

4. Draft the Relevant Experience section. Use:

Using only the project examples I provided, draft the Relevant Experience section. For each project, structure it as: Client description, Scope of work, Outcome. Match the language of the RFP's evaluation criteria where possible. Flag any requirement in the RFP's experience section that my provided projects do not clearly address.

The flag at the end of that prompt is important. If your past projects don't map cleanly to the criteria, you need to know before you submit, not after.

5. Draft Methodology/Approach, Key Personnel, and Pricing using the same pattern — one section per prompt, always with the instruction to use only your supplied source material and to flag gaps.

6. Run the word-count trim step. Many RFPs impose strict word or page limits per section. Once you have a draft, paste the section back in with:

The [section name] must not exceed [X] words. Condense the draft below to meet this limit without removing content that directly addresses the evaluation criteria. Flag anything you had to cut.

The Compliance Check Pass

Once all sections are drafted, run a final self-audit pass before you touch a single Word document or portal form.

Review this full draft tender response against the original RFP requirements. List every mandatory requirement from the RFP and confirm whether the draft response addresses it. Mark each as: Addressed, Partially addressed, or Missing. For any partially addressed or missing item, quote the relevant RFP clause.

This step consistently catches omissions that a tired human reader misses. The UK's Procurement Act 2023{:target="_blank"}, effective February 2025, increased transparency and simplified bid structures specifically to help SMEs compete — but a compliant response structure still requires methodical checking.

Handle compliance declarations separately. Insurance certificates, signed declarations, ABN or company registration numbers, and license documents are pass/fail items that AI cannot generate. Missing one disqualifies your entire submission regardless of how strong the technical content is. Keep a physical checklist of these items and attach them last, after AI drafting is complete.

Common Mistakes Small Businesses Make When Using AI for Bids

Submitting without fact-checking line by line. AI models will hallucinate — they can invent plausible project outcomes, reference numbers, or client names if your source material is thin. Every data point in your final submission must trace back to something you provided or can verify. This is not a minor risk. A fabricated detail in a government bid submission is a compliance failure.

Using AI for the whole document in one prompt. A single "write my tender response" prompt produces generic output that doesn't map to the evaluation criteria. The section-by-section workflow above produces measurably better results because each prompt focuses the model on one task with one set of constraints.

Ignoring the word limits. RFP portals often enforce character or word limits at the field level — you cannot exceed them on submission. Drafting without the limit in mind means a reformatting scramble at the end. Set the constraint in the prompt before you draft.

Treating AI output as final. AI is a drafting tool, not a bid writer. Your final response should read like it was written by someone who knows your business deeply, because it was — you're the one who supplied the inputs and reviewed every line.

What to Do Next

The highest-leverage next step is building a reusable "bid library" — a single document with your company background, standard project descriptions, key personnel CVs, and relevant certifications that you maintain and update quarterly. Every tender you bid on starts from that document, which cuts input preparation time from 2 hours to 20 minutes by the third bid. For more on building internal business documentation that AI tools can actually use, see how to build an AI-ready knowledge base for your small business.

You can also use AI to decide whether a tender is worth bidding on before you invest any writing time — how to use AI to evaluate whether an opportunity is worth pursuing covers that process in detail.

FAQ

Is it allowed to use AI to write a government tender response? Yes. Procurement rules govern the content and accuracy of submissions, not the tools used to write them. Using AI to draft a tender is no different from using a professional bid writer, which has always been permitted. What matters is that the content is accurate, compliant, and represents your business honestly.

Do I need a paid subscription to use AI for bid writing? For basic text drafting, the free tiers of ChatGPT{:target="_blank"} and Claude{:target="_blank"} are sufficient — you can paste RFP text and your source material directly into the chat window. File upload functionality (to upload a PDF directly) requires ChatGPT Plus or Claude Pro, both at $20/month as of early 2026. Pricing checked February 2026 — check their sites, as these change.

How long does it take to write a tender response using this method? Realistically, 4–6 hours for a straightforward RFP with six to eight sections, assuming you have your source material assembled before you start. Without pre-assembled inputs, add 2–3 hours. Compare this to the 15–20 hours a first-time tender response typically takes without AI assistance — the UK's Federation of Small Businesses{:target="_blank"} found that time cost is the primary reason over 60% of small businesses that considered public bidding chose not to pursue it.

What's the ROI on bidding for government contracts as a small business? The honest answer is: it depends on contract size, your win rate, and how much time the bid process costs you. The U.S. Small Business Administration{:target="_blank"} notes the federal government's 23% small business contracting goal across $650 billion in annual spend. Even a single contract win at $50,000–$200,000 — a realistic range for small service businesses — justifies a significant bid preparation investment. The break-even calculation is straightforward: if your time costs $75/hour and the bid takes 6 hours ($450), any contract with a margin above $450 is net positive on the first win.

Can I reuse AI-drafted tender sections across multiple bids? You can reuse your company background and key personnel sections with minimal edits. The methodology, relevant experience, and pricing sections must be tailored to each specific RFP's scope and evaluation criteria — reusing them verbatim is one of the clearest signals to evaluators that a response is generic. AI makes customization fast enough that there's no good reason to submit boilerplate.
