Project Shopify App

I need you to develop some software for me. I would like this software to be developed using PHP. Project Shopify App Create a fully created Shopify app that is published on their marketplace. I want to see examples of a published Shopify app on their marketplace. (including bug fixes I find and especially Shopify finds before publishing to the marketplace) Features: UI: - Option to import inventory with picture, description, and pricing by variant to my platform. - Will import customer phone numbers to my customer subscriber list and create new list. - Will export updated inventory quantity as items are sold. - Will export customer sales and order delivery info to Shopify store. Settings: - auto import customers (if yes, to which list or option to create new list) Other: I want to be sure Shopify store owners can't just install once and then have full functionality forever. So however the integration is done, make sure there is a server call that checks for valid subscription or any other verification way you can think of. This will be a public app with a small monthly fee, so anything needed to make that work. Free user - No access Trial user - full access for x days Paid user - full access for duration of payment plus commission. Must be partner friendly. Partner friendly apps can be installed for free by Shopify Partners. These apps are free to test in development stores. And the app partner only charges once the store is switched over to a paid plan. User = store owner
