> Shopify Merchants are selling roughly $80B a year, at least 5x WooCommerce merchants. Paying Shopify 20% means you net at least three times higher monthly revenues over paying WooCommerce zero commission.

This seems a weird way to calculate potential eCommerce platform plugin profits because (unless you are a payment gateway), the quantity of stores is more important than the volume those stores sell, and WooCommerce is by far the most popular eCommerce platform.

For example, Kylie Jenner's Shopify store has approx. $330mm[1] in revenue a year as far as I can tell, but that's only going to translate into one potential plugin purchase.
