Lately, we have been receiving more and more inquiries from users who see an e-invoice in the FiskApp (eTax) application, but cannot find it in the bizBox system. Such situations often cause concern and unnecessary panic, so below we explain what to do and when further steps are needed.
Wait up to 24 hours first
If the e-invoice is visible in FiskApp, but not yet displayed in bizBox, we recommend waiting up to 24 hours.
Reason:
- processing is sometimes delayed on one side or the other,
- fiscalization and delivery of e-invoices are not the same process and do not take place simultaneously.
In a large number of cases, the e-invoice appears in bizBox within that period.
If there is no e-invoice after 24 hours
If the e-invoice does not appear in bizBox after 24 hours:
- it is very likely that the e-invoice was rejected,
- The most common reason is that the e-invoice XML does not comply with the prescribed schema or standard.
In that case, we recommend:
Contact your supplier and ask them to check the e-invoice with their ERP system or information broker.
Why is the e-invoice fiscalized, but you still don’t receive it?
It is important to understand the following:
- The Tax Administration does not receive the entire e-invoice,
- in the fiscalization procedure, only certain data, sent in a special XML structure for fiscalization, are checked,
- this is not the same as the UBL XML e-invoice that is delivered to the recipient.
Therefore, it is possible that an e-invoice is fiscalized, even though:
- UBL XML is not technically correct,
- or does not meet the conditions for further processing by the recipient.
Why does bizBox perform validation?
In the bizBox system, we perform complete technical and content validation of incoming and outgoing e-invoices.
In accordance with applicable rules and technical specifications, certified service providers should conduct technical and content verification of the XML structure of e-invoices, both at the input and output of the system.
In practice, however, the level of checks and the consistency of their application vary between providers, which can lead to situations where incorrect e-invoices are still forwarded further into the system.
This means that:
- Invalid e-invoices cannot be received or displayed,
- We thereby protect users from problems in accounting, payments and further business processes.
If the e-invoice does not pass validation, in bizBox:
- not visible,
- and cannot be processed further.
At bizBox, we consistently carry out full validation of all incoming and outgoing e-invoices, in accordance with applicable standards, in order to minimize such situations and protect users.
