I will have an e-commerce website connecting to my own REST API that will connect to a MySql Database.
I want to be able to connect a POS(Point of Sale) in a physical store to this same REST API and allow for real time syncing e.g. when an product is purchased online, the inventory is updated to reflect the quantity of that product remaining, and this updated inventory of that particular product will also be updated in the POS. I want this same behaviour to be achievable if the product was bought from the physical store using the POS. How do I achieve this?
I have no problem with the e-commerce website part, but I don't know where to begin with the POS part of the physical store. Do I have to create my own POS or can off-the-shelf POS achieve this?
Any advice will be greatly appreciated,
John
