Read the message
When a Restaurant POS screen cannot do something, it says why, and nothing is recorded: no bill, no invoice, no half-finished change. The message names what is missing and, where it can, the screen that fixes it (usually something in Accounting). Fix that, then do the action again.
All messages and what to do: Messages you may see. Problems by what you see: Problems by symptom.
The usual causes
| You see | Usually |
|---|---|
| Orders cannot be sent: "No cash shift open" | Your cash shift is not open: Open and close the cash shift |
| A bill is refused | Bill numbering, the default bank or the bill terms in Accounting are not set for today: VAT, service charge, discounts and bill numbers, Payment methods, banks, QR and the store |
| A dish is missing or cannot be added | The product is not on the menu, or it is marked unavailable: The menu: dishes and drinks are products |
| A ticket did not print | The station's printer route, or the printer: Printers for kitchen tickets and bills |
| No Bill button | The role may not bill: Staff: users, roles, waiters and the secret key |
| A void cannot be done | The dish is already done, or the secret key is asked: Void an item |
| A table shows the wrong status | A check is still open, or the merge was done on another device: Open a table and start a check, Move a party to another table, or merge tables |
Most of these are setup that was never finished: Before the first order: the setup checklist.
When the message does not help
Take a screenshot of the whole screen, with the message, and note what you were doing (the table, the bill number, the time). Send it to the person who supports Penahak for your restaurant. When the message says nothing was recorded, you can try again once the cause is fixed.
