Define what offline means for this system
A disconnected POS may stop accepting payments, queue certain transactions, or retain only order records. Ask the provider to describe the supported behavior, limitations and security responsibilities in writing. Do not assume that a successful screen message proves that funds have been authorized or settled. Staff need clear instructions for the particular device and payment arrangement.
Prepare a queue reconciliation sheet
Use non-sensitive order references to record the sale time, amount, device, payment status and later provider result. Keep stock movement and payment status separate: an item can leave the shop while its payment remains unresolved. Identify who is allowed to resume processing and who will contact the customer when the supported procedure requires follow-up. Never create an improvised paper list of complete card credentials.
Test recovery with an approved scenario
In a provider-approved environment, simulate a lost connection, restore it, and compare queued orders with the provider’s final records. Check duplicate detection, declined transactions and receipt behavior. For example, a cashier’s second attempt may create another order even if the first payment later completes. The recovery checklist must identify both records before anyone attempts another collection or refund.
Close the incident with balanced totals
Reconcile successful payments, unresolved items, voids and inventory changes. Record any remaining financial exposure without treating it as cash already available. A Florida seasonal business should include outage recovery in opening preparation and cash-flow planning. Review the procedure after changing devices or providers, and keep the provider’s approved acceptance limits distinct from the business’s own willingness to carry an unpaid sale.
Sources and next steps
The workflow above is an operational method. Consult the current primary resource: PCI SSC merchant payment process guidance. It does not establish compliance, guarantee acceptance or replace the provider’s instructions for a live case.
