Why German Businesses Rely on a Specialist E-Invoicing Provider
An e-invoicing provider supplies the platform that turns billing data into structured electronic invoices and delivers them to business customers. In Germany, Section 14 UStG defines an e-invoice as a structured file that follows EN 16931 and can be processed automatically, so image-based PDFs and paper no longer fit this definition.
2nd Paragraph (≈345): The change is phased. All businesses have had to be able to receive e-invoices since 1 January 2025. Issuing becomes mandatory on 1 January 2027 above €800,000 prior-year turnover and on 1 January 2028 for others. The invoice issuer remains responsible for content, so confirm details with the BMF or your tax advisor.

Integrate Your E-Invoicing Provider with Existing Finance Systems
Most German finance teams work with an ERP, a bookkeeping tool and a tax advisor. A provider should sit alongside these, taking invoice data from billing, producing valid structured files and returning delivery and receipt status. This keeps records consistent and reduces duplicate entry between systems.
Advintek supports e-invoicing workflows for Germany. Before deployment, confirm supported formats, delivery channels, ERP connectors, hosting details and implementation scope, and review current guidance from the Federal Ministry of Finance (BMF).

Frequently Asked Questions
1. What does an e-invoicing provider do for companies in Germany?
It provides the platform to create invoices as structured files, validate them, deliver them to customers and receive supplier invoices. It can also store records. The company issuing the invoice still decides content and tax treatment and remains responsible for compliance with UStG rules.
2. How do I know if an e-invoicing provider is reliable?
Review hosting location, GDPR terms, security measures, uptime commitments, support options and references from similar businesses. Test real invoice scenarios before signing. Ask how legal changes are handled and request a clear exit process, so you can export your records if you leave.
3. Can one provider manage invoices for several German entities?
Many providers support multiple legal entities, but features differ. Ask whether each entity can have its own settings, numbering, users and archive, and whether reporting can be combined. Confirm this in the contract, because each issuer must meet its own invoicing duties under UStG.
4. Does my provider need to be located in Germany?
German law does not prescribe the location of an e-invoicing provider. However, data protection and tax record rules still apply, so ask where data is hosted and processed. Review GDPR terms and check with your tax advisor whether any storage location raises questions for your audits.
5. Which German e-invoice formats should a provider support?
At minimum, XRechnung and ZUGFeRD in profiles that meet EN 16931. Other structured formats may be acceptable if both sides agree. Public authorities generally expect XRechnung. Ask the provider which versions it supports and how quickly it adopts updates published by KoSIT.
6. Can a provider help me prepare for the 2027 and 2028 deadlines?
A provider can help you test structured output, set up receiving and train users before your date. The 1 January 2027 duty applies above prior-year turnover, and 1 January 2028 applies to others. Confirm which date applies to you with the BMF or your tax advisor.
7. What happens to my invoice data if the provider has an outage?
Ask the provider about availability commitments, backup arrangements and recovery steps. Your contract should explain how delayed deliveries are handled and communicated. Because you must still issue and keep valid invoices, maintain access to your own copies of original structured files.
8. How does a provider handle personal data in invoices?
Invoices contain names, addresses and sometimes contact details. A provider usually acts as a data processor under GDPR, so you need a data processing agreement. Review the technical and organisational measures, subcontractors and deletion terms, and seek advice from your data protection officer.
9. Can I use a provider alongside my existing ERP?
Yes. Most providers connect to ERP or accounting systems through files, APIs or standard connectors. Your ERP supplies billing data, and the provider produces and delivers structured invoices. Confirm which connectors are available, who configures them and how errors are reported back.
10. Is Advintek an e-invoicing provider for German businesses?
Advintek offers e-invoicing solutions for the German market. Before implementation, verify supported formats, hosting details, ERP integrations and timelines. Confirm your legal obligations with the Federal Ministry of Finance (BMF) or your tax advisor, as the rules are being introduced in stages.
