Does BYOB support POS?

No, we don't support POS at this moment. This is because the Shopify cart transformation API doesn't support POS. Shopify is working on POS but can't give a concrete timeline. When Shopify can support POS, we will re-evaluate the POS integration. 

If you are interested in using BYOB on POS, kindly let us know more about your use cases, e.g., if your staff use barcodes. We'll see what the best solution is available.
