Should I use a retainer or bill hourly?

Retainers favor you when the client's needs are predictable and you can deliver efficiently. Hourly is safer when scope is unclear or workload spikes are unpredictable. Many freelancers run a small retainer base + hourly overages — the retainer guarantees minimum income, the hourly rate captures upside.

How long should the term be?

Three to six months is the sweet spot for first retainers — enough commitment to make it worthwhile, short enough to walk away if the fit is bad. Auto-renewal with a 30-day notice period works well for established relationships.

What happens to unused hours at the end of a month?

Your call — but make it explicit. Most freelancers do "use it or lose it" to keep monthly billing predictable. Some allow up to 50% rollover for one month. Whatever you choose, write it into the contract so there's no end-of-month renegotiation.

Service Agreement for Freelancers

Retainers that don't quietly turn into unpaid overtime.

A service agreement for freelancers running ongoing client work — clear monthly scope, defined SLAs, and a clean termination clause when the relationship runs its course.

Retainers are great until the client treats your monthly fee like an all-you-can-eat buffet. This service agreement defines exactly what's included each month, what's out of scope, and how either side ends the engagement — so the relationship stays clean even as it evolves.

Why freelancers need a service agreement

Monthly scope caps keep retainer creep from eroding your effective hourly rate.
Auto-renewal with a notice period stops the relationship from accidentally lapsing or accidentally continuing.
Defined SLAs (response times, turnaround) prevent vague "availability" expectations.
Pause and termination clauses give you an exit when the work no longer fits.
