FactoorSharp.FacturX.Validator

FactoorSharp.FacturX.Validator is a .NET library for validating Factur-X (ZUGFeRD) and XRechnung documents against technical rules and format requirements.

It is part of the FactoorSharp product family and is designed for automated validation of electronic invoices in backend systems, import pipelines, and compliance workflows.

You can find all available license options here:
https://www.factoorsharp.de

Overview

The library accepts XML invoices and hybrid PDF invoices (PDF/A-3 with embedded XML). It automatically detects the file type and forwards the content to the FactoorSharp validation service for a comprehensive check.

The returned result combines the overall validation outcome with specialized sub-results for the XML payload, the PDF container, and the XML embedding.

Features

  • Validation of Factur-X (ZUGFeRD) XML and hybrid PDF documents
  • Validation of XRechnung (UBL and CII formats)
  • Automatic detection of XML and PDF input
  • Detailed validation results (XML, PDF, and embedding checks)
  • Synchronous and asynchronous API
  • Stream-based and file-path-based input
  • Designed for backend processing and automation scenarios

Supported Platforms

  • .NET Standard 2.0 / 2.1
  • .NET Framework 4.6.1, 4.6.2, 4.8
  • .NET 8, .NET 10

Installation

Install the package via NuGet:

dotnet add package FactoorSharp.FacturX.Validator

Usage

Register under https://www.factoorsharp.de and download the trial license.

Validate from a file path

FacturXValidator.SetLicense("your-license-key");

ValidationResult result = FacturXValidator.Validate("invoice.xml");

if (result != null && result.SummaryStatus)
{
    // The document passed validation.
}

Validate from a stream

FacturXValidator.SetLicense("your-license-key");

using (Stream stream = File.OpenRead("facturx.pdf"))
{
    ValidationResult result = await FacturXValidator.ValidateAsync(stream).ConfigureAwait(false);

    if (result != null && result.SummaryStatus)
    {
        // The document passed validation.
    }
}

Check service availability

if (FacturXValidator.IsAvailable())
{
    // The remote validator can be contacted successfully.
}

Licensing Model

FactoorSharp is a commercial product licensed per company. The license model is based on the following principles:

  • The license is granted to a company, not to individual users
  • Usage is based on the number of developers working with the library
  • Different license tiers are available (e.g. Freelancer, SME, Corporate)
  • Customers are expected to select a license that reflects their actual usage

The model follows a fair-use approach and does not enforce strict technical limits.
