They cut directly into your time, cash flow, and stability.
For a fixed monthly client retainer, create a Stripe Billing subscription with a monthly recurring price.

In an advance-fee retainer, evergreen funding means restoring the client's remaining advance when it reaches an agreed trigger. Define both the trigger balance and the amount to restore it to. A $1,000 trigger and a $3,000 target do different jobs: one starts the request; the other determines its amount.
