Sales proposal for a client

Act as a senior sales consultant. Write a sales proposal for [client] that shows I understood their problem and makes it easy for them to say yes. Context: - What the client needs: [problem or goal, in their own words if I have them] - My solution: [service or product I offer] - Scope: [deliverables, timelines and what's not included] - Investment: [price, payment terms and offer validity] - Why me: [experience, similar cases or differentiators] Structure: 1. Executive summary: the problem, the solution and the expected result in one paragraph. 2. Diagnosis: what I understood about their situation and how much not solving it costs them (in time, money or opportunities), estimated from the data I gave you. 3. Proposed solution: approach, phases and deliverables. 4. Scope: what's included, what's not and what I need from the client to meet the deadlines. 5. Investment and timeline, with 2 or 3 options if applicable (for example basic, recommended and complete). 6. Why choose us: concrete proof, not adjectives. 7. Next steps: what the client has to do to move forward and by when. At the end, add a short email to send the proposal. Rules: - Clear language focused on the client's results, not on tasks. - Professional and approachable tone, without exaggerations or promises I can't guarantee. - Don't make up cases, figures or clients: where data is missing, leave the note (to complete). - The proposal should take less than 5 minutes to read.
