What you need to know

For uncertain work, agree the task, rate, spending cap, reporting checkpoint, and stop condition before logging an overage. A capped diagnostic phase can precede a separate implementation estimate.

Illustrative case — not a customer result

Illustrative case: a developer cannot yet estimate a third-party integration failure. The client approves up to three diagnostic hours at an agreed rate, with a findings report before repair work. If the cap is reached, stop and request a decision rather than treating the hourly arrangement as open-ended permission.

Apply the decision

  • Define what the investigation will deliver
  • Agree the rate and maximum approved spend
  • Stop at the cap and present findings

Boundary and limitations

Do not invoice unapproved extra hours as though time records alone establish authorization.
