There are two ways to print an invoice for your WP Simple Pay Pro plugin purchase to keep for your records.
Note this is not for generating invoices for customers who purchase on your sites using WP Simple Pay Pro. You’ll instead need to configure email receipts through Stripe.
First, log in to your WP Simple Pay account, then scroll down to Purchases.
To print the standard purchase receipt, simply click View Purchase Confirmation and print.
To print a more customized invoice, click Generate Invoice. On the next page fill out all the fields you require, then click Save Billing Details & Generate Invoice.
Once your invoice is generated you can use your browser’s File -> Print menu to print a pdf and/or save a copy on your computer.
