POS & Cash Handling: the full procedure
Run every transaction and cash movement through the POS accurately so the drawer balances and money is secure.
- Applies to: Cashiers, shift leads
- Frequency: Every transaction; per-shift reconcile
- Scope: Covers transaction processing, refunds, and cash control at the point of sale. PCI/payment-network rules and the merchant agreement govern card handling; this SOP owns the consistent business process for accuracy and security.
What you need
- POS terminal
- Cash drawer and safe
- Opening float
- Refund/void authorization rules
- Drop log and deposit slips
- End-of-shift reconciliation sheet
The procedure, step by step
- Open with a counted float — Count the starting drawer to the set float at the beginning of the shift and record it; discrepancies are flagged before any sale.
- Ring every sale through the POS — Enter the correct package or add-on for every transaction — no untracked or off-book sales.
- Handle payment securely — Process cards per the terminal and merchant rules; never write down full card numbers and never share register access.
- Make change deliberately — Count change back to the customer and keep large bills visible until the transaction is complete to prevent disputes.
- Drop cash above the threshold — Move cash over the drawer limit to the safe per the owner’s drop procedure, logging each drop.
- Authorize refunds/voids properly — Process refunds and voids only with the required approval and reason recorded, per the owner’s policy.
- Reconcile at end of shift — Count the drawer, compare to the POS report, record over/short, and secure the deposit and float.

Frequently asked questions
How often should the drawer be reconciled?
Count and record the float at the start of every shift and reconcile the full drawer against the POS report at the end, noting any over/short. Cash above the drawer limit should be dropped to the safe and logged during the shift. Consistent counting is what keeps the drawer balanced and surfaces problems early.
How should card payments be handled at the register?
Process cards through the terminal per your merchant agreement and never write down full card numbers or share register logins. Card-data handling is governed by PCI standards and the merchant rules, which this SOP defers to. The SOP’s job is the consistent business process — ringing every sale, authorizing refunds properly, and reconciling.
