Billing by batch size
For API flows, billing is based on how many entries are actually included in a mailing batch. The trigger window only decides when a batch is formed. If you do not have enough credit, the batch is still created and prepared; it is printed once the amount is covered. New batches use the published price list, including material, finish, address check, Plus individualization and payment discounts. Prepayment and credit are available, and invoice once PostPal enables it for the account, when offered by that list.
API flows are billed by the actual batch size. The relevant number is how many entries are really included in a mailing.
The trigger window only controls when PostPal forms a batch. It is not the basis for billing.
If your credit is not sufficient for a batch, it is still created and prepared; its entries belong to that mailing and are not processed again. It is printed once the amount is covered. After a top-up PostPal reserves the amount automatically.
Payment method in an API flow
Prepayment and credit are supported for API flows, and invoice once PostPal enables it for the account, when offered by the published price list - the same choice as for campaigns, see Payment method. If a new price list no longer offers your current method, the form points this out and you pick another one before saving.
The payment method selected in the flow applies to that flow only and does not overwrite your account setting. The invoice address from the flow, in contrast, is additionally stored as the account default.
Price list and estimate
The estimate includes the selected material, finish, address check, Plus individualization and payment discounts. The actual batch size can differ from the minimum quantity per shipment. Any minimum order quantity in the price list applies to production costs.
Each new batch keeps the price list published at its creation. Later price changes do not affect an existing mailing; quantity changes use its fixed price list as well. Older mailings retain their previous billing terms.
