My question is that I am using 19 multi-store. I understand that I will no longer be able to send and receive files between stores and that I will need a new merchant processor. If I want to continue to use QB 19.0, is there a way to switch from multi-store to single store so each store can have the same authorization? for example, my remote location cannot enter new products. if I switch to single store, would they be able to?

thank you in advance.
