How Much of Your E-Commerce Revenue Do You Have?

The founder of Shopify says about 60% of his revenue now comes from digital products. In March, he sold a little over $18,000 worth of product and didn't do any marketing because he was afraid it would sell out. Now this year, "it's been mostly ads" for him on Facebook and Google. The company is spending maybe $50 a day across Facebook and Google to run shopping ads.
