If a Brink terminal displays an error of "No Item Found for SKU" followed by a SKU, this indicates that Brink is searching for a Menu Item instead of a guest, redeemable, coupon or other value. This normally occurs when searching for a guest's Punchh Account but has been seen to occur when scanning a QR code for a redeemable as well. Please contact Brink to resolve.
An additional, and possibly the root issue, is that this can indicate that an update or change made by Brink has been pushed out and that Brink will need to be contacted in order to resolve this issue, as they have developed this integration, not Punchh. This is likely triggered by scanning a QR code or hitting a loyalty button on the POS after a Brink update or change has been pushed to that terminal.
