Secure Payment Processing Flow
The Transaction Hold function allows cashiers to temporarily suspend active sales transactions without completing the payment cycle. This capability ensures that goods are reserved while payments remain unprocessed, preventing inventory overselling and protecting revenue integrity during high-volume periods. By parking a transaction, the system locks specific line items in a pending state, making them unavailable for other customers until the original order is either finalized or cancelled. This feature is critical for managing complex orders where additional verification is required before final authorization, such as checking credit limits or resolving customer disputes mid-transaction.
When a cashier initiates a hold, the system immediately flags the associated items as reserved in the inventory ledger. This prevents duplicate sales of the same stock to different customers, maintaining accurate real-time availability across all store locations.
Held transactions remain visible on the cashier terminal for up to 30 minutes unless manually cleared or expired. During this window, staff can add new line items or modify quantities before converting the hold into a completed sale or refunding it entirely.
The function integrates directly with payment gateways to delay authorization codes, allowing time for manual review without triggering immediate financial commitments from the customer's account.
Operational Workflow Steps
Initiate a hold by selecting 'Park Transaction' in the POS interface and confirming the selected items and subtotal amount.
The system generates a unique hold ID and displays a countdown timer, alerting staff to complete actions within the allowed time window.
Cashiers can attach internal notes explaining the reason for the hold, such as pending manager approval or customer credit verification.
