Is a PDF invoice e-invoice?
Short answer
No. PDF invoice is an electronic document for a person but is generally not structured e-invoice. Mandatory e-invoice is the data document in form XML, which meets EN 16931, Peppol rules and Slovak requirements. PDF can be attached as a visualisation or supporting document but does not replace mandatory XML supplier, customer, item data, VAT and total amounts.
Readable to Man
It can help control, but it is not the basis of a mandatory e-invoice.
Readable for the system
Contains structured fields for automatic processing.
Appendix
PDF may be attached if supported by the system and the beneficiary.
Control of rules
The form, contents shall be checked, VAT logic; and Peppol rules.
Conclusion
PDF may be useful, but mandatory e-invoice stands on structured XMLwhich passes the validation and can be delivered through the specified mode.
