Read the message
When a till screen cannot do something it says why, and nothing is saved: no bill, no half-finished return. 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 |
|---|---|
| "Terminal has not been set yet. Please contact your supervisor." | The computer is not bound to a terminal: Terminals: register a till and bind its computer |
| A list of items to set in the configuration page | The shop's settings, numbering or warehouse: Open the till and accept the cash, Set up a shop for the retail POS: checklist |
| "Please hand over the previous day's cash." | An earlier day's cash hand over is still open: Hand over the cash at the end |
| A product is not found, or the list is empty | The product is inactive or locked, or the branch has more than one default warehouse: Find and add products |
| Not in stock | The stock of the branch's default warehouse is used up: Quantities, units and the stock limit |
| "Please pay full amount to proceed." | The payment is less than the total: Take the payment: cash, bank and wallet, Sell on credit to a named customer |
| "Deposited bank not selected" | A bank or wallet payment has no bank: Take the payment: cash, bank and wallet |
| The receipt does not print | The printer or the desktop app; or the branch has no receipt design: Print the receipt and reprint a bill, Receipt design: what the printed receipt shows |
| A bill has no receipt in Accounting | A numbering series is missing for the branch: When the payments reach the books, Numbering series the till needs |
| A return cannot load the bill | The bill was already returned, or the number is wrong: Sales return: take goods back |
| A button is missing (Void/Reset, Loyalty discount card, Gift card) | The role or a setting is off: Who may do what: roles, scopes and the supervisor role, Configuration settings the till uses |
Most of these are setup that was never finished: Set up a shop for the retail POS: checklist.
When the message does not help
Take a screenshot of the whole screen, with the message, and note what you were doing (the bill number, the till, the time). Send it to the person who supports Penahak for your shop. When the message says nothing was saved, you can try again once the cause is fixed.
