Please follow our blog to find out when we launch this feature.
In the meantime, try looking into the following features to help sell more of your products to your customers:
An optional feature, this allows you to show other similar products (created by you and by other Gumroad creators) after each sale.
With some coding chops, you can use our Ping feature to automatically handle specific tasks – send emails to your customers, tweet at them, add their email address to your mailing list on Mailchimp, etc. etc.
Set up a post-sale workflow to thank your customers and let them know about other products that you offer. Send them offer codes and incentives for buying more products from you.
Upload all of the files you want associated with this product, and then create different priced versions of that same product for customers to buy from.
