POS shift opening, cash float, and shift closing

The Point of Sale (POS) module enforces strict cash controls and shift accountability. 1. Shift Opening: When starting a cashier session, enter the physical opening cash float in the drawer. The system logs the timestamp, cashier user, and terminal ID. 2. Daily Transactions: Cash, card, and digital wallet sales are automatically recorded against the open shift session with real-time stock deductions. 3. Cash Drops and Adjustments: If cash is removed during the shift for safe deposit, record an auditable Cash Drop transaction with reason notes. 4. Shift Closing and Reconciliation: At the end of the shift, perform a blind or verified cash count. Enter physical totals for cash, card slips, and vouchers. The system highlights any variance, generates the Z-Report closing summary, and links the reconciliation to the general ledger.
