Can you create a private app for each of your customers? I know it would be a lot more challenging and you wouldn't get free marketing from Shopify's app store, but from my understanding private apps aren't subject to Shopify's commission and at least you would have more control over your business.

> Unless otherwise indicated in this Agreement or agreed to by Shopify in writing, under the App Plan, an App Developer is entitled to eighty percent (80%) of the total revenues from the sale of, subscription to or charges relating to the Public Application, with Shopify being entitled to the remaining twenty percent (20%).

> “Public Application” means an Application that accesses the Shopify API via an API Client and that is made available to Merchants either via a URL or through the Shopify App Store, and that is not a Custom Application.

> “Private Application” means an Application that accesses the Shopify API via Private API Credentials and is made available to a single Merchant.

You could in theory, but this requires having each merchant go into their admin and manually grant you scopes and then copy/paste the api key and secret to you. Definitely not a scalable way to go about it.
