What are post-payment invoices for one time purchases?

You can generate paid invoices as proof-of-payment for one time purchases on Checkout and Payment Link sessions. These invoices will be generated and emailed directly to your users from Stripe. They’ll also be made available on your account, where you can issue credit notes on the invoice.

What is the pricing for this feature?

Post-payment invoices are not an Invoicing feature and are priced separately.

The fee for post-payment invoices for one time purchases is 0.4% on the transaction total, up to a maximum of $2 USD (or local currency equivalent) per invoice.

This functionality is also available for subscription payments and is included in the Stripe Billing pricing.
