Valitool
The leading solution for accurate validation of electronic invoices
Java-based validation for EN16931-based e-invoice formats
Valitool is the leading Java library for the precise validation of XML-based or hybrid electronic invoices. As a reliable partner for quality assurance, our tool has established itself in various industries.
Every month, more than 100,000 invoices are checked before they are sent or received. Full integration with server, desktop software, document management software and other applications makes invoice verification seamless and efficient.
Why validation with Valitool
Compliant with the law
Valitool goes beyond the official validation rules and guarantees conformity with the UStG and GoBD.
Industry profiles
With an understanding of the special requirements of different sectors, such as energy suppliers and the consumer goods industry, Valitool checks complete discount determinations at item level and also handles foreign currencies.
Precise validation
In contrast to XSLT with Saxon, which can have difficulties with rounding amounts, Valitool delivers precise results without the need to calculate with approximate values.
Excellent performance
While Schematron reaches its performance limits when validating large or complex calculations, Valitool offers outstanding performance and speed for demanding validation tasks.
HybridDoc.Valitool - The solution for hybrid invoices
With HybridDoc.Valitool you can validate hybrid invoices such as ZUGFeRD and Factur-X.

ValiMerge: Hybrid invoices in ZUGFeRD format
ValiMerge requires a PDF/A file with the document image and the associated XML invoice to create a hybrid invoice in ZUGFeRD format. By merging the two files, ValiMerge enables the creation of compliant ZUGFeRD invoices. In addition, ValiMerge is ideal for embedding additional file attachments such as invoice supporting documents in the PDF/A file.
