Checkout

Choose a plan in Settings, then Billing. You are sent to a Stripe Checkout page to pay. When payment succeeds you return to the app and your plan updates within seconds.

Customer portal

Use the portal to change plan, update your card, download invoices and cancel anytime. Open it from Settings, then Billing, then Manage billing. A cancelled plan stays active until the end of the period you paid for.

Failed payments

If a payment fails, your plan stays active for 7 days while Stripe retries. After that the account falls back to the Free plan limits. Your data is kept.

Billing webhooks

Billing state is synced from Stripe through a webhook at https://inboxwire.buffersoltech.com/api/stripe/webhook. The endpoint verifies the Stripe signature and is idempotent, so retries are safe. You do not need to configure anything as a customer.
