What is a retainer agreement?
A retainer agreement is a contract in which a client pays a fixed fee each month to reserve a service provider's time and receive ongoing services. Marketing agencies, bookkeepers, IT support providers, designers, developers, PR consultants and virtual assistants all use retainers to replace a stream of small one-off jobs with a predictable monthly arrangement.
The client gets guaranteed access to a provider who knows its business; the provider gets steady, plannable income.
Types of retainer
| Type | How it works | Best for |
|---|---|---|
| Hours-based | Fee covers a set number of hours each month; extra hours are billed | Mixed, unpredictable requests |
| Deliverables-based | Fee covers a fixed list of outputs (e.g. 12 posts, 1 newsletter) | Repeatable work with a clear output |
| Availability-only | Fee reserves access; work is billed separately | Advisers on call, specialist support |
This template is built for hours-based retainers, but you can list fixed deliverables in the services description too.
Key clauses explained
- Monthly fee and included hours – what the client pays and how much work that buys.
- Billing in advance – retainers are normally paid at the start of the month, which is what separates them from ordinary hourly billing.
- Rollover policy – whether unused hours expire, carry over partly, or carry over for a few months. A clear rule avoids the most common retainer dispute.
- Overage rate – the rate for work beyond the included hours, with a warning before you exceed them.
- Minimum term and notice – how long the client commits for and how much notice either side gives to stop.
- Rate review – an optional clause letting the provider adjust prices once a year, with notice and a right for the client to leave.
How to use this template
- Enter both parties' legal names and addresses.
- List the services the retainer covers, and anything that will be quoted separately.
- Set the monthly fee and included hours. The hourly rate calculator helps you work out a sensible fee; many providers price retainer hours slightly below their one-off rate in exchange for commitment.
- Choose a rollover policy, overage rate, payment terms, minimum term and notice period.
- Switch optional clauses on or off and download the PDF for both parties to sign.
Tips and common mistakes
- Don't let hours pile up indefinitely. Unlimited rollover can leave you owing months of work at the end of the contract.
- Report hours monthly. Log time with the time tracker and send a short summary with each invoice.
- Invoice on the same day every month. Use the invoice generator and keep the client's running balance on a statement of account.
- Define what is out of scope. Big one-off projects should get their own quote or service agreement.
- Chase late payments early. The payment reminder generator writes a polite follow-up in seconds.

Frequently asked questions
How does a monthly retainer work?
The client pays a fixed fee at the start of each month. In return the provider reserves time and delivers the agreed services, usually up to a set number of hours. Work beyond those hours is billed at an agreed overage rate.
What happens to unused retainer hours?
That depends on the rollover policy in the agreement. Common options are that unused hours expire each month, that a limited share rolls over to the next month, or that hours roll over for a few months before expiring. Choose one in the form so there is no argument later.
Should a retainer be paid in advance?
Usually yes. Billing in advance is standard for retainers because the fee reserves the provider's capacity for the coming month. Extra hours are then billed in arrears with the next invoice.
How much notice should a retainer have?
30 days is common for small businesses, sometimes with an initial minimum term of 3 to 6 months so the provider can recover set-up time. Longer notice periods are more typical for larger or more specialised engagements.
Is a retainer the same as a deposit?
No. A deposit is an advance payment towards a specific project. A monthly retainer is a recurring fee for ongoing services and reserved availability. In some professions, such as law, a retainer can also mean money held on account, which follows special rules.
