My partner wants me to test 8 different orders to cash flows. Do I have to go through all of that testing?

Some retailers assign generic testing to all of their suppliers. Before testing all flows, you should read the testing instructions and understand if some flows don’t apply to your line of business with your retailer. You should then request your retailer testing exemptions.

For example, if you only ship products directly to your retail stores, you should not test the dropshipping flows/scenarios.
