RETAIL TRANSACTIONS & STOCK
Point of Sale (POS)
Point of sale is the transaction context where a customer purchase is recorded. A POS system supports that sale through the relevant hardware, software and payment or inventory integrations.
POINT OF SALE IN PRACTICE
- Record the transactionIdentify the product, unit and selling context.
- Connect the systemsReconcile payment, order and stock events.
- Control the exceptionHandle returns, voids and offline recovery.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A receipt and a stock update need a reliable connection.
A store sells a product while connectivity is interrupted. The business verifies later synchronization and avoids double-posting when the system reconnects, rather than assuming every local transaction already reached every channel.
