FAQ

Prioritize reliable checkout, accurate inventory synchronization, unified customer and order history, flexible returns, suitable hardware, clear payment fees, and the ability to support every store location and sales channel.
Can a POS system replace inventory management software?
It can for simpler retailers, but merchants with complex purchasing, forecasting, bundles, warehouses, manufacturing, or lot and serial tracking may still need a dedicated inventory or ERP system.
