A till that keeps selling when the line drops.

A named cashier opens a shift against a till profile with counted balances per payment mode. The device already holds its catalogue, prices, and rules.

Items scanned or searched locally, batch and serial captured, discounts and loyalty applied by rule, payment split across modes — online or not.

Queued sales replay in order, posting stock and ledger as they would have. Anything that cannot post is raised as an exception, not discarded.

Counted against expected per mode with the difference recorded, and the shift's sales consolidated into invoices the ledger carries as one document.
