A retainer agreement gives you predictable monthly income and gives your client guaranteed access to your time. Here is how to structure one.

Types of retainers

Fixed-hours retainer: Client pays for X hours per month at a set rate. Unused hours may or may not roll over.
Value-based retainer: A flat monthly fee for ongoing services (e.g., social media management, monthly reporting).
Access retainer: Client pays for priority access or availability, with work billed separately.
