How to write a sales proposal after a discovery call
The best sales proposal is the one the client reads and thinks "this is exactly what we talked about". To get there, it has to come from the call, not from a generic template, and arrive while the conversation is still fresh. Here's how.
Send it while the call is fresh
The later the proposal arrives, the more interest cools and the more details both sides forget. If you agreed on the call to send it, do so within one or two working days at most, and if you can't, say when it will arrive.
To write it fast you need what the client said at hand: their needs, their timing, their budget if they mentioned it and who decides. Without notes, the proposal ends up as a brochure.
A structure that works
Context: the client's situation, as they described it. Needs: the problems and goals they expressed, in their words. Proposed solution: how you answer each need, point by point. Scope and deliverables: what's included and what isn't.
Timeline and milestones, if discussed. Investment: price, payment terms and how long the offer is valid, clear and with no small print. Next steps: what needs to happen to start, with a date and an owner.
Common mistakes
Talking more about your company than about the client; promising features, deadlines or discounts that never came up; leaving the price vague ("from…", "on request"); and ending without a dated next step.
Another frequent one is copying internal things into the proposal: your margin, what you think of the client or your negotiation strategy. Always check what the client is going to read.
The AI draft, straight from the call
If you recorded the call with SwiftBOL (or the assistant joined the video call), open "Create with AI" and choose "Sales proposal". You get a draft with the context, the client's needs in their words, the solution point by point, scope, timeline and next steps, built only from what was said on the call.
It never invents prices, discounts or commitments: if they weren't said, it leaves placeholders such as [Price] or [Start date] for you to fill in. And it leaves out internal details that shouldn't reach the client.
Before you send it
Check every figure, deadline and commitment: what you put in a proposal can end up as part of the contract. Add your price, adjust the tone to your brand and make sure the client knew the call was recorded. Then send it and put a reminder in your calendar for the follow-up.
