Retainer agreement template
A retainer is the best thing that can happen to a freelance business and the easiest to get wrong. This short agreement sets what a month includes, what it costs, and what happens at the edges.
Two kinds of retainer
An hours retainer sells a block of time each month (say 10 hours of design). A deliverables retainer sells a fixed output (four blog posts, two social videos). Deliverables retainers are easier to price and to invoice because the client never has to trust a timesheet; use them whenever the work is predictable.
The template
Invoice on the first, work when it's paid
Clause 2 is the one that keeps retainers healthy: the month starts when the invoice is paid, not when the calendar turns. It quietly removes the possibility of doing March's work while chasing February's money.
No rollover, ever
Rollover sounds generous and turns into a liability: a quiet quarter becomes 30 banked hours the client expects in one week. If a client pushes, offer a small rollover cap (up to 2 hours) rather than open-ended banking.
Raise the rate once a year
Add a line: "The retainer fee is reviewed every 12 months." It makes the conversation routine instead of awkward.
