Hey @petgrocer .
Thanks for reaching out.
I appreciate the context that you have shared with us as that is very helpful. I can definitely see how beneficial it would be to allow you to issue store credit from the Shopify POS application to a specific customer account. I am going to provide this as a suggestion to our developers to hopefully include this feature in the future. It is feedback just like this that allows us to build a better platform for merchants just like yourself, we appreciate you reaching out and providing your feedback.
Let me know if you have any questions.
