Every submission attempt whether successful or failed is logged in the **Integration Request** doctype. This is your primary audit and debugging tool.



**Navigation:** `Search Bar → Integration Request` → filter by `Reference DocType = Sales Invoice`

### Status Lifecycle


| Status        | Meaning                                                                                                                   |
| ------------- | ------------------------------------------------------------------------------------------------------------------------- |
| **Queued**    | The invoice has been submitted in ERPNext, and the request to Tevin has been queued but not yet sent (initial state)      |
| **Completed** | Tevin returned a success response; CU number and QR code are stored on the invoice                                        |
| **Failed**    | The submission attempt failed (network error, invalid payload, Tevin server error); check the **Error** field for details |
