Frequently Asked Questions
Answers to the most important questions about Docuflair Invoice
What is Docuflair Invoice?
Docuflair Invoice is a web-based e-invoicing engine for creating, converting and validating European e-invoicing standards. The software supports all common formats such as XRechnung, ZUGFeRD, Peppol BIS Billing, FatturaPA, EB-Interface and more - without XML knowledge or specialist expertise.
Which e-invoicing formats are supported?
Docuflair Invoice supports nine European e-invoicing standards: XRechnung (UBL 2.1), ZUGFeRD/Factur-X (all profiles from MINIMUM to EXTENDED), Peppol BIS Billing 3.0, FatturaPA (Italy), EB-Interface and Austrofix (Austria), Finvoice (Finland), FA_VAT for the Polish KSeF system as well as Facturae (Spain). All formats are 100% XSD-validated.
What does 100% XSD-valid mean?
XSD validation means that every generated e-invoice is checked against the official XML schema of the respective standard (validated against official XRechnung/ZUGFeRD schemas). With Docuflair Invoice, there are no partial implementations or "best effort" exports - what the system generates corresponds 100% to the technical requirements and is accepted by recipient systems.
Can I convert between different e-invoicing formats?
Yes, Docuflair Invoice converts losslessly between all supported e-invoicing formats. For example, you can convert an XRechnung to FatturaPA or a ZUGFeRD document to Peppol BIS - ideal for international business relationships and different authority requirements.
Does Docuflair Invoice support credit notes?
Yes, credit notes and corrective invoices are generated standard-compliant in all nine formats — as UBL CreditNote (XRechnung, Peppol), type 381 (ZUGFeRD, Austrofix), TipoDocumento TD04 (FatturaPA), RodzajFaktury KOR (FA_VAT/KSeF) or corrective invoice (Facturae). Document- and line-level charges and allowances, delivery addresses, billing periods and VATEX tax exemption reasons are covered as well.
Can Docuflair Invoice create and validate ZUGFeRD hybrid PDFs?
Yes. Docuflair Invoice embeds invoice XML into PDF/A-3 (ZUGFeRD/Factur-X hybrid), extracts embedded XML from existing hybrid PDFs and validates hybrid PDFs directly — the embedded invoice is detected automatically and checked against EN 16931. For large volumes, batch validation and conversion with ZIP and CSV export are available.
Is Docuflair Invoice EN-16931 compliant?
Yes, the European standard EN 16931 is at the heart of Docuflair Invoice (per EN 16931 and XRechnung Standard 3.0). All generated invoices comply with the semantic data model of this standard. Profile rules are explicitly considered, and validation is fully traceable and explainable.
Who is Docuflair Invoice suitable for?
The solution is aimed at businesses and SMEs with e-invoicing obligations (B2G, B2B), software vendors and ERP manufacturers who want to integrate e-invoicing functions, tax consultants and accounting service providers for validation and conversion, as well as IT service providers and system integrators for customer projects.
Is an API offered for developers?
Yes, Docuflair Invoice offers a REST API for developers and system integrators in addition to the web-based user interface. This lets you seamlessly integrate e-invoicing functionality into existing ERP, accounting or inventory management systems - including batch processing for large invoice volumes.
Can Docuflair Invoice be operated on-premises?
Yes, Docuflair Invoice can be operated as a web-based solution as well as on-premises or in a private cloud or in the cloud. Companies with special security requirements or compliance regulations thus retain full control over their invoice data within their own infrastructure.
Can Docuflair Invoice automatically validate VAT numbers?
Yes, Docuflair Invoice automatically validates VAT identification numbers via the official VIES interface of the European Commission. In addition to simple validity checks, qualified requests with company name and address verification are also supported. Every validation is logged with a consultation number in an audit-proof manner.
You can also validate VAT numbers for free using our online VAT number validation tool.
