You can add a digital product to either an Auto Fulfillment or Custom Fulfillment Catalog to help increase your sales!
Navigate to your Store > Products section, select the Catalog you wish to modify, and click on the Add Product button.
Select the "Digital Download" option
Choose the download type, set the desired size of the digital file and enter a price to be displayed to your client.
You’re able to add multiple digital products if you’d like your clients to have different options for download sizes to purchase.
