The WP PDF Stamper plugin can be integrated with the WooCommerce plugin so your customers get a stamped copy of the PDF file when it is sold via the WooCommerce plugin.

How the PDF Stamping Process Works with WooCommerce

The following points show the usual flow of events that you can expect from the integration:

1. A customer want to purchase your WooCommerce product (A PDF file), so he pays for the product.
2. After the payment, the customer gets a download link to download the PDF file(s).
3. When the customer click on the download link, the PDF stamper will stamp the file and serve the stamped copy of the PDF file to the customer.

Your customers will always see/receive the stamped copy of the PDF file when they go to download a PDF file that they purchased.
