When using OpenFiskal for Shopify POS in test mode, we’ve added a clear message on printed receipts to indicate that they are for demo or test purposes only. The German message displayed is: „Achtung: Dieser Beleg wurde zu Testzwecken erstellt und ist nicht für den tatsächlichen Gebrauch bestimmt“, which translates to “Warning: This receipt was created for testing purposes and is not intended for actual use”. This ensures clarity and avoids any confusion during testing or any misuse of test receipts.
