How do I structure a retainer clause for ongoing services?

How should payments and scope be structured?

The clause should state the retainer amount, how often it is paid (such as monthly), and when payment is due. It should also explain how work is applied against the retainer, such as hourly billing or a defined set of services.

The scope of services should be clearly defined, including what is covered under the retainer and how additional work outside that scope will be approved and billed.

The agreement should also clarify the nature of the retainer, including whether:

• It is earned upon receipt (for example, a fee to secure availability), or
• It is an advance payment for future services that is billed against over time.

This distinction affects how funds are handled and whether unused amounts may be refundable.

What happens to unused hours or funds?

The agreement should clearly explain how unused time or funds are treated. Common approaches include:

• allowing limited rollover to future periods
• applying unused amounts as a credit
• setting an expiration period for unused services

If unused amounts expire, the terms should be reasonable and clearly disclosed, as overly restrictive expiration provisions may be challenged as an unenforceable forfeiture.

If the retainer is structured as an advance payment for future services, the agreement should also explain whether unused amounts are refundable at termination and how final billing will be handled.

What to do next...

1. Set a clear monthly or recurring retainer amount.
2. Define what services are included and excluded.
3. Decide how unused hours or funds are handled.
4. Put all terms in writing in the agreement.

What to consider in your specific situation

Retainer structures can vary based on your services and client relationships.

• The type and frequency of services you provide.
• How predictable your workload is each month.
• Client expectations for flexibility or rollover.
• Your cash flow needs and pricing model.
• Industry norms for retainers and billing.
