What Is a POS System? — The Complete Guide
A POS (point of sale) system is software that records sales and invoices, updates inventory, and shows cash-register reports in restaurants, stores, and pharmacies.
The core job a POS system does is connect the moment of a sale to everything downstream from it — the receipt, the inventory deduction, and the daily report — instead of leaving those three things to be reconciled by hand later, which is where most small-business accounting errors actually originate.
