Post Affiliate Pro uses very flexible payouts system. It allows you to define your own payout system with features like export format or payment button. All the defaut payout options are defined using this flexible system, and it is easy to modify it.
You can create/modify payout option and its fields in Settings area of merchant panel.
When you edit or create payout method (option) you can specify its name, export and button format. Export format defines how the payment data should be exported. For example, here we see definition for PayPal Mass Pay system.
Button format allows you to create payment buttons if you want to pay directly from affiliate system. The example shows you button code for PayPal.
Payout method can have multiple configurable fields which have to be filled by affiliates. In this example we define field for PayPal, the only thing needed is paypal email of an affiliate. Pay affiliates screen shows you the payments due, the minimum payout chosen by affiliate and the payout method.
From this screen you can pay affiliates either one by one, or by exporting data and using automatic method.
For one by one payments you can use payment buttons, if they ate defined for the method used, to pay money directly from the program.
Here you can see the payment via PayPal.
Another type of payout is by export file. You can generate export file for specified affiliates and then process the export file manually (for example for wire transfers) or automatically by PayPal Mass Pay functionality or similar.
