Subscription and payment lifecycle

Catalog, trial, checkout, YooKassa, webhook, subscription, and usage projection.

Catalog

The published regional catalog is the source for price, period, discount, trial, and limits. The client must not invent commercial terms from hard-coded values.

Payment

1
The server creates an idempotent checkout.
2
The user confirms amount at YooKassa.
3
Browser return shows an intermediate state.
4
Verified webhook or reconciliation updates subscription.
5
Usage projects into effective quotas.

Security

A return URL status is not proof of payment. Authenticity, amount, currency, and identifiers are verified server-side.

A note on availability

Features depend on plan, role, connected marketplace, and data readiness. ProfitVena does not replace primary marketplace statements or regulated accounting and legal records.
