What to Look for in E-Invoice Software for German Companies

E-invoice software for Germany should create invoices as structured electronic files that follow the European standard EN 16931, not as image-based PDFs. Under Section 14 UStG, an e-invoice is issued and received in a structured format that software can read automatically. It should also capture all mandatory invoice details.

German e-invoicing is being introduced in stages. All businesses have had to be able to receive e-invoices since 1 January 2025. Issuing duties start on 1 January 2027 for businesses above  prior-year turnover and on 1 January 2028 for the rest. Check your own timeline with the BMF or your tax advisor.

E-Invoice Software Features for German Business Needs

Structured Creation

Generate invoices as machine-readable XML files that carry every mandatory business term required in Germany.

Format Support

Work with XRechnung, ZUGFeRD and other EN 16931 formats, depending on what each customer or authority accepts.

Inbound Capture

Receive supplier e-invoices through a dedicated inbox and keep the original structured file as the legal invoice.

Tax Data Checks

Review VAT rates, exemptions and reverse charge notes before an invoice is released to the customer.

Network Delivery

Send invoices by email or over the Peppol network, using the channel your recipient is set up to accept.

Retention Storage

Store unaltered invoice files for the eight-year period under the Fiscal Code and Section 14b UStG.

E-Invoice Mistakes to Avoid in Germany

  • Do not send a plain PDF when a structured file is required.
  • Avoid ZUGFeRD profiles that lack the full EN 16931 data.
  • Keep one unique invoice number on every document.
  • Show the supply date or service period clearly.
  • Match tax rates and exemption codes on each line.
  • Do not edit the XML after the invoice has been issued.
  • Store the original file, not only a printed copy.

Integrate E-Invoicing with Your Current Business Software

Most German companies already run an ERP or accounting tool. E-invoice software should connect to it, so invoice data moves from order to payment without retyping. Structured data also helps approvals, VAT deduction checks and reporting for your tax advisor.

Advintek supports e-invoicing workflows for Germany. Before deployment, confirm supported formats, Peppol or email delivery, ERP connectors and implementation scope, and review current guidance from the Federal Ministry of Finance (BMF).

E-Invoice Software Control Points

Pre-Send Validation

Test each outgoing file against EN 16931 rules so errors are fixed before the customer receives the invoice.

Receiving Workflow

Route inbound e-invoices to the right team for review, approval and posting while the source file stays intact.

Correction Handling

Issue credit notes and corrected invoices that refer to the original document and adjust the tax amounts.

Access and Audit Log

Record who created, changed or approved each invoice so records are ready for the Finanzamt or advisor.

Frequently Asked Questions

1. What is e-invoice software and how does it work in Germany?

E-invoice software creates, sends, receives and stores invoices as structured electronic files instead of paper or plain PDFs. In Germany, these files must follow EN 16931 so that the recipient’s system can process the data automatically. The software also checks mandatory details and keeps the original file for tax records.

 

Under Section 14 UStG, an e-invoice must be issued in a structured electronic format that follows EN 16931 and allows electronic processing. It must also contain the mandatory invoice details. Paper invoices, plain PDFs and scanned images are treated as other invoices, not as e-invoices. Confirm details with the BMF.

 

 

Yes. Since 1 January 2025, every business in Germany, including small businesses, must be able to receive structured e-invoices in domestic B2B transactions. A dedicated email inbox can be enough for receiving. Small businesses under Section 19 UStG may be exempt from issuing them, but not from receiving. Verify with your advisor.

 

 

Check that it can create and validate EN 16931 files, read inbound invoices, handle credit notes, and archive original files unaltered. Also review ERP integration, delivery channels, user access controls and how updates follow changes announced by the BMF. German law does not name a specific software.

 

 

The German B2B duty applies to domestic supplies between businesses established in Germany. Invoices to private consumers are outside it, and cross-border invoices may follow other rules. Check your cases with the BMF or your tax advisor, and confirm what formats your foreign customers accept before sending.

For B2B invoices, German law does not require one specific channel. A structured invoice can be sent by email or another agreed method, provided the recipient can process it. Peppol is widely used and accepted by public authorities. Confirm what each customer or authority supports before choosing the delivery method.

Input VAT deduction depends on holding a valid invoice. When an e-invoice is required, the structured file is the original document, so it must be kept and remain readable. Software can store the file and show it in a readable view. Confirm deduction questions with your tax advisor or the Finanzamt.

Yes. Corrections are usually made through a credit note or a corrected invoice that clearly refers to the original document and adjusts the tax amounts. The correction should follow the same structured format rules as the original. Ask your tax advisor how to treat specific cases, such as changed tax rates.

E-invoices must be kept unaltered, readable and available for tax audits. Since 2025, the retention period for invoices is eight years, while books and annual financial statements still require ten years. The original structured file must be stored, because a PDF copy does not replace it.

Advintek offers e-invoicing solutions for the German market. Before implementation, verify supported formats, delivery channels, ERP integrations and your invoicing volumes. Confirm your legal obligations with the Federal Ministry of Finance (BMF) or your tax advisor, as the rules are being introduced in stages.
