A proposal is a response to a requirement, not a shortened biography. The client should quickly understand why your approach fits the work and what they would receive if they select you.
Open with your understanding
Summarise the problem in your own words and identify the outcome that matters. Avoid repeating the entire project description. Mention one detail that materially affects the approach, such as an existing system, a production constraint or a required deadline.
Then describe the first steps you would take. If important information is missing, identify it as a question rather than making a confident but unsupported assumption.
Show relevant evidence
Include one or two examples that match the requirement. Explain your contribution and the deliverable, using only information you are permitted to share. A relevant small project can be more persuasive than a large but unrelated brand name.
Google's people-first content guidance is written for websites, but the same editorial discipline is useful here: make the content help the intended reader, rather than adding generic material for volume.
Make the offer clear
State the deliverables, schedule assumptions, dependencies and pricing basis. Explain how you will handle revisions and requirements that change after agreement. Propose a discovery milestone when uncertainty prevents a dependable implementation quote.
End with a few useful clarification questions and a concrete next step. Proofread names, figures and links before sending. If AI helps draft the response, check every claim against your actual experience.
Use WorkFry's project listings to identify suitable opportunities, then tailor each proposal to the requirement. A focused response is easier to assess than a generic pitch sent unchanged to every client.
