Using this POS the orders and invoices are generated in the OpenCart database. And a single database is shared for physical store and your online store. So if you have a physical store you can prefer order, billing & invoicing upon this platform. This will assist your both physical and online order and billing to synchronize and maintain balanced inventory. Also there are some amazing features on TMD OpenCart POS Module and Extension that I would like to share with you.
