Retainer agreement guide

How to structure a setup fee plus monthly retainer agreement

Many service offers have two payment moments: an upfront setup fee and an ongoing monthly retainer. The agreement should make both clear before the client signs.

What to include in the payment section

The payment section should identify the one-time setup amount, recurring amount, billing frequency, start date, and what happens if payment fails or service is paused.

  • Setup fee amount and due date
  • Monthly retainer amount
  • Billing start date
  • Renewal or cancellation terms

Why this should live in one document

When setup and recurring payment terms are split across separate invoices or links, clients can misunderstand what they accepted. One signed document gives the business and client a clearer record.
