Sell what they'll have at the end

Consulting is hard to picture, which makes it hard to buy. Describe the engagement by what the client will hold at the end (a clear picture, a plan, a first launch) rather than the hours or meetings it takes. The approach section can explain how you'll get there.

Fixed length, fixed fee

An open-ended hourly arrangement asks the client to trust that the hours will add up to something. A fixed-length engagement with a fixed fee and named deliverables is easier to approve, and it protects you from a project that never quite ends.

Example numbers only: an 8-week engagement at $9,000, with optional advisory at $1,500 a month afterwards. Price from the time you'll really spend, including interviews and analysis.

Make your dependencies explicit

Consulting projects stall when access and people aren't available. List the accounts, reports and interviews you need, and name who should attend the key sessions. If they're late, the timeline in the proposal already says what happens.

Plan the next step inside this proposal

Offer an optional advisory or implementation retainer as a line in the investment section. The client doesn't have to decide now, but the path to working together after the engagement is already on the table when the plan is delivered.
