As of 13 August 2026, AI can make your sales proposal more persuasive.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the current proposal, the buyer's brief or emails, relevant meeting notes, your price list, delivery constraints and approved case studies.
   2. Paste those materials into a chatbot using the prompt, separating verified customer information from your own claims and commercial constraints.
   3. Ask the chatbot to produce the revised proposal, change log and complete Needs checking list in one response.
   4. Compare every factual claim, price, date, deliverable, result and customer reference in the draft with the source documents and remove anything unsupported.
   5. Read the proposal as the buyer and check that the opening, value case, objections and next step address their stated decision criteria rather than your internal priorities.
   6. Ask a colleague who understands the account to challenge the central promise, scope and tone, then apply only changes that remain accurate.
   7. Send the approved proposal through your normal sales process and retain the source documents and final version.

   Prompt

   Make the sales proposal below more persuasive for the named buyer without inventing facts, results, customer needs, prices or commitments.
   
   Buyer and situation:
   [buyer name, organisation, role and buying situation]
   
   Customer's stated needs and success criteria:
   [ paste verified information from the brief, meeting notes or email ]
   
   Our verified evidence:
   [ relevant capabilities, case studies, results, accreditations and delivery details ]
   
   Commercial constraints:
   [ price, scope, dates, terms, exclusions and promises we are allowed to make ]
   
   Current proposal:
   [ paste the full proposal ]
   
   Produce:
   1. A revised proposal in clear UK English, keeping the original structure where it works.
   2. A sharper opening that connects the buyer's stated problem to the proposed outcome.
   3. A concise value case focused on the buyer, not on generic claims about us.
   4. A clear explanation of scope, deliverables, price, assumptions and next step.
   5. A short objections section covering only objections supported by the supplied information.
   6. A change log explaining what you changed and why.
   7. A list headed "Needs checking" containing every claim, number, date, promise or customer reference that requires my confirmation.
   
   Use a confident, specific and plain tone. Remove hype, clichés and unsupported superlatives. Do not make the proposal sound cheaper, faster, safer or more effective than the evidence allows. Do not add a testimonial, statistic, deadline or guarantee. If information is missing, mark it as [NEEDS INPUT] rather than guessing.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
