SellerExpress allows you to upload a PPI for each shipping method you offer. This means you can have a PPI uploaded for Amazon Standard orders, another for eBay 2nd Class and a third for International Orders. A PPI option will become available for each method on the Invoices Screen (Settings > Invoices).
When you first setup your account only the "Default PPI Label" option will be available. As orders are download with other shipping methods then they will also become available on the Invoices Screen. I.e, Amazon Standard will not appear on this screen until you get an order from Amazon with a Standard Shipping rate.
