# Understand monthly and annual billing

> Compare billing cycles and understand subscription renewal dates.

A billing cycle is the period covered by a subscription charge. The billing page shows the current cycle and next renewal information.

Changing plans or billing frequency can affect the amount and effective date. Review the checkout or confirmation summary for any immediate charge, credit, or next-cycle change before approving it.

Invoice dates and service dates can differ when a payment is retried or adjusted.

## Read the cycle

The billing page identifies the subscription period and the expected next
renewal. An invoice records the actual charge attempt and can have a different
creation, due, paid, or retry time.

## Change frequency

When the interface offers a different billing frequency, select it and review
the confirmation summary. It should state whether the new cycle begins
immediately or at renewal and whether a charge or credit applies.

Do not calculate prorations manually. Taxes, discounts, credits, and provider
rounding are reflected in the checkout or invoice produced for the workspace.

Record renewal dates in the timezone and format shown by billing, and keep a
valid default payment method before the next attempt.

## Frequently asked questions

### Why is an invoice date different from renewal?

Creation, payment retry, and service-period times can differ. Open the invoice
for its exact covered items and status.

### When does a cycle change start?

The confirmation shown before purchase is authoritative for immediate or
next-renewal timing.
