A post paid affiliate program is a program with a billing system for all generated commissions.
When commissions have been generated, advertisers have a contractual time (Approval Time) to process them. Otherwise, they will be automatically accepted. During that timeframe, commissions have a Pending status.
After processing the commissions, they are either Approved or Rejected, depending on the order completion and/or validity of leads.
On a date agreed along with the advertisers (either monthly, bimonthly or weekly), we issue invoices that includes all accepted commissions that were not included in the previous invoice.
Once the invoice containing all commissions is paid, those commissions will become automatically Paid and they can be withdrawn by affiliates.
