Track retainer usage in real time—not at invoice time

An agency sells monthly retainers but tracks usage in a spreadsheet that's updated inconsistently, so clients get surprised by overage charges or, worse, get free work the agency never bills for. Build a system where usage is visible as it happens.

A retainer without real-time tracking is a guess

If usage against a retainer only gets tallied at the end of the month, both sides are flying blind in between—the client doesn't know if they're approaching their limit, and the agency doesn't know if it's giving away unbilled work.

Track usage against the allocation as work is logged, and flag it before either side is surprised.

From allocation to renewal
  1. 1. Client signs a retainer agreement with a monthly allocation
  2. 2. Work is logged against the retainer as it happens
  3. 3. Usage is tracked against the allocation in real time
  4. 4. Approaching or exceeding the allocation triggers a client conversation
  5. 5. Retainer resets or renews on its billing cycle

Example build brief

Example prompt
Build a retainer management app with monthly hour or budget allocations, work logged against the retainer, real-time usage tracking, and threshold alerts before overage.

Scenarios to test in your preview

  • Usage must not silently exceed the allocation without a flagged alert to the account manager.
  • A monthly reset must not erase the usage history needed for client reporting.
  • Unused hours must only roll over if the agreement's rollover rule allows it.
FAQ

Common questions about retainer management software

Who is this for?

Agencies, legal practices, and consultants that bill clients on a recurring retainer instead of per-project.

Can retainers vary by client?

Yes—each client's allocation, rollover rule, and overage rate can be set independently.

Does this handle the billing itself?

Yes—connect Stripe billing once usage tracking and overage rules are confirmed correct.
