Hello, I have an ERP system to manage selling business. With clover SDK, can I build an Android app, which will scan bar code from our platform, call an API to retrieve receipt information and payment method from the ERP. After that, will wait for charging card of customers and print receipt or just print receipt (if payment method is cash). Another concern is we must upload the app to clover store market, right? I think it will take few weeks. I appreciate If have any solutions easier to implement. Thank you!
