These things NEVER go in a proposal
A proposal is not a negotiation document. It’s not a place where you indicate gifts or incentives may come to the buyer.
Don’t stick a bunch of charts in the proposal they’re just going to make the proposal hard to understand.
A proposal is not a place for a detailed list of deliverables. A simple high level summary with bullet points will do it.
Take out the staff bios and company history. If they don’t know you and that you can do the project then you’re already on the back foot and having them here is just going to make them think harder before maybe saying yes.
The sole job of a proposal is to get the buyer to make a purchase with you. Basically leave everything else out.
