Upgrades & Downgrades
- Upgrades take effect immediately; prorated charges appear on the next invoice.
- Downgrades or plan cancellations take effect at the end of the current term. Feature reductions apply upon renewal.

- Duplicate or erroneous charges raised by Stark billing systems.
- Cancellations within the initial 14-day onboarding period (Starter & Professional plans only).
Beyond these cases, fees are non-refundable. Stark may issue goodwill credits at its discretion.
