How do I look up a customer quickly when they arrive?

Open Customers, select the search/filter icon above the table, and enter a name, email address, or customer number.

If a phone-number search returns no match, use one of those identifiers instead. In the demo, the displayed number did not return the customer in either international or national-digit format.

Customer Registration also provides a USB QR Code Reader tab with a Paste UUID or Customer Number... field.
