Retainer

Retainers turn brand work from a series of separate deals into a standing arrangement: a set number of integrations, posts or videos each month for a set fee, usually over a fixed term of several months. You get income you can forecast and the brand stops renegotiating every time.

Scope is what kills them. A vague retainer becomes an open invitation for extra requests, calls and revisions nobody priced, so write down exactly what a month includes, what counts as extra, and how either side ends it. Build in a review point so the rate can move.
