Upgrade and downgrade
Users should not be allowed to check out for the same plan they already have. Plan changes must verify that the provider-side subscription actually changed.
Dodo Payments flow
Billing is handled through Dodo Payments. In local development, Sonar is currently running against test mode.
- The user chooses a plan on the subscription page.
- Paid plans redirect the user to Dodo checkout.
- After payment, Dodo redirects back to Sonar.
- Sonar syncs the checkout and verifies subscription status before updating local plan access.
- Starter has a three-day trial configured in Dodo.
Plan management
Cancel to Free
Paid users can cancel their subscription, which moves the account to the free plan and free-plan limits.
Webhook note
- Local development does not have a public webhook endpoint.
- Webhook integration should be added once the app has a public domain.
- Until then, subscription verification relies on checkout sync and direct provider status checks.
