E-Invoice - Basics, Requirements & Benefits

Electronic invoicing, also known as e-invoicing, optimizes invoice management and facilitates the integration of invoices and compliance documents.

By digitally processing invoice data and matching it with contracts, orders, service sheets, and goods receipts, the risk of errors and exceptions is minimized. Since digital information is more easily accessible across systems than paper-based documents, electronic invoicing offers numerous advantages:

  • Management and control of compliance tasks via a dashboard
  • Simplified collaboration within the company and with business partners
  • Optimization of cash discounts and current assets
  • Reducing the risk of overpayments and fraud
  • Improved cash flow for suppliers through faster payments
Legal framework

Mandatory e-billing in Germany

The Growth Opportunities Act, introduced by the Federal Government in March 2024, aims to advance the digitalization of the economy. An important component of this law is the Promotion electronic invoicing. SAP users are encouraged to digitize paper-based processes and use standardized e-invoice SAP formats such as ZUGFeRD.

ZUGFeRD and XRechnung are the two central formats for electronic invoices in Germany — and they are both based on the European standard EN 16931.

XInvoice

A purely XML-based format,.

ZUGFeRD

A hybrid approach: a visually readable PDF invoice with an embedded XML file containing all structured invoice data. This makes ZUGFeRD invoices both human-readable and machine-readable—an advantage for companies with traditional invoicing processes.

For many companies, this means: ZUGFeRD is particularly convenient for B2B direct shipping, XRechnung is the secure format for authorities and public institutions.

Avoid risks

Why correct validation is crucial

An incorrect or invalid e-invoice can have serious consequences. According to the BMF letter of October 15, 2025, three main types of errors are distinguished:

Formatting error

an invalid XML structure results in the Invoice technically not recognized as a compliant e-invoice, resulting in rejection and process failure.

Content Error & Input Tax Deduction

If, for example, a valid VAT ID number is missing or amounts do not match, there is a risk of the invoice not being recognized — and thus the loss of the input tax deduction.

Business rule error

Automated processes are being sabotaged, leading to increased workload through manual checks, inquiries, and corrections.

Documentation obligation

Those who cannot demonstrate correct validation run the risk of significant exposure during operational audits or regular audits.

Before you implement an SAP e-invoicing solution, it’s worth taking a look at the basics. Three tools, in just a few minutes, with no registration required and no data transfer.

Our Solution

Automation of e-invoices - with CICS and CBCS

Regardless of which SAP system you use, we offer you an uncomplicated and, compared to alternative solutions, extremely cost-effective option for the entire incoming and outgoing invoice process. Our services integrate smoothly into existing SAP landscapes, reduce implementation costs and ensure that your e-invoices are always processed in a standard-compliant, validated and automated manner.

What is CBCS?

Brief definition

CBCS (Cloud Billing Conversion Service) is a cloud-based e-invoicing SAP solution for outgoing invoicing. CBCS automatically generates legally compliant e-invoices, for example in XRechnung or ZUGFeRD format, from a classic PDF + metadata.

Purpose

Generate invoices that comply with legal requirements — without manual XML coding or complex ERP customizations.

Especially relevant for

Companies that need to send invoices automatically and want to ensure compliance.

Technical Requirements: CBCS requires at least SAP ERP 6.0 EHP7. Newer systems such as S/4HANA and RISE with SAP are of course fully supported.

What is CICS?

Brief definition

CICS is an inbound conversion service that analyzes, reads, and transmits incoming invoices into a structured, machine-readable format.

Purpose

Validate the receipt of e-invoices and ensure they comply with legal requirements (e.g., according to EN 16931) — particularly relevant since the new audit obligations of the BMF.

Result

Structured XML invoice that seamlessly flows into the internal accounting/ERP/financial system.

New to CICS & CBCS

Consistently further developed

Who is CICS/CBCS suitable for?

Our e-invoicing SAP services CICS and CBCS are suitable for all companies with SAP systems that process a medium to high volume of invoices, regardless of whether you use SAP ERP (ECC, for CBCS from Release 6.0 EHP7), SAP S/4HANA, on-premise, RISE with SAP, SAP S/4HANA Cloud Public Edition, or hybrid landscapes.

Especially in complex SAP environments, the two services offer a decisive advantage: they relieve the system of complex conversion, checking, and formatting processes and ensure fast, automated, and standard-compliant processing for incoming and outgoing data. This makes CICS and CBCS ideal for companies that

  • process many incoming and outgoing invoices per month,
  • are looking for a standardized, streamlined solution for all e-invoice formats,
  • want to modernize their SAP landscape without major projects or expensive add-ons,
  • must reliably ensure compliance and validation,
  • want to relieve internal resources – without changing their existing system architecture,
  • even if parts of your corporate group do not use SAP,
  • also have to process e-invoices outside of Germany.
Globally usable

E-invoicing beyond Germany

Many of our customers operate not only nationally but also have national companies, subsidiaries, or suppliers in Europe and internationally. CICS and CBCS have been further developed to cover the requirements of additional countries beyond XRechnung and ZUGFeRD — without you having to set up a separate technical connection for each country.

Questions & Answers

E-Invoicing SAP: The Most Important Questions

Legal obligations

E-invoicing will become mandatory in the domestic B2B sector, while paper invoices are to be phased out in the long term. E-invoices must be archived electronically for eight years; a printout is not sufficient. Exceptions apply to small-value invoices up to 250 euros, as well as transport tickets, tax-exempt services, invoices to private individuals, or purely private services to entrepreneurs.
Every entrepreneur must be able to receive and process e-invoices as early as January 1, 2025. For sending: optional in 2025/2026, mandatory from January 1, 2027, for companies with previous year's revenue exceeding 800,000 euros, and mandatory from January 1, 2028, for all domestic B2B transactions. Small businesses are exempt from issuing invoices but must still be able to receive them.
Starting in 2025, a pure PDF document will no longer be considered an e-invoice, but only a miscellaneous invoice. A valid e-invoice must be in a structured, machine-readable format, and its authenticity must be technically ensured.
Exclusively structured electronic formats according to EN 16931: XRechnung in all current versions, ZUGFeRD from version 2.0.1, and EN-16931-compliant EDI formats. Paper invoices, pure PDFs, and scanned paper invoices do not meet the requirements.

Formatting & Standards

XRechnung is a pure XML format and mandatory for public contracting authorities (B2G). ZUGFeRD is a hybrid format: a PDF with embedded XML data, readable by both humans and machines – ideal for B2B with differently digitized recipients. Both fulfill the German e-invoicing mandate based on EN 16931.
Peppol is a Europe-wide network for the structured transmission of electronic business documents. For many public contracting authorities, it is already mandatory, while for pure B2B it is currently optional, but it is gaining increasing importance through international business and ViDA. CICS and CBCS optionally support the Peppol connection.
You provide the input format (PDF or XML), the service converts it into the necessary structure, validates it according to EN-16931 rules, and returns a compliant file — ready for SAP, Peppol, or archiving.

Validation & Compliance

A non-valid e-bill cannot be processed technically or in terms of content. Authorities and many companies reject them. The invoice process stops, queries arise and delays occur.
Yes. If the invoice does not contain mandatory information or if amounts or tax rates are incorrect, the deduction of input tax can be denied. An examination of the content is therefore just as important as technical validation.
GoBD-compliant and audit-proof in original format (XML, ZUGFeRD PDF/A), electronically available for eight years. We use proven archival solutions from our partner DOXIS Solutions or integrate existing archiving systems according to your specifications.

Select CICS & CBCS

For SAP users, we recommend CICS for incoming invoices and CBCS for outgoing invoices. Both services integrate seamlessly into SAP ERP, S/4HANA and RISE environments.
CBCS requires at least SAP ERP 6.0 EHP7. All newer systems – SAP S/4HANA (on-premise and cloud) as well as RISE with SAP – are fully supported. Are you unsure which release you are using, or are you using an older system? Contact us – together we will find the right path to e-invoicing.
Yes – and that's one of our key advantages. CICS and CBCS are intentionally designed to be system-independent and can also be used where there is no SAP standard, such as in subsidiaries with different ERP systems or with suppliers who do not have their own SAP landscape.
Yes. Beyond XRechnung and ZUGFeRD, our solution increasingly covers the format requirements of other countries. Contact us to discuss which countries are relevant for your company.
Yes. Through our dashboard, you can see at any time how many invoices have been processed, where validation errors occurred, and the current status of your outgoing invoices.
No. CBCS works with the existing standard SAP invoice printing. The cloud service takes the PDF generated by SAP, validates it, converts it to PDF/A, and enriches it with the structured XML data according to EN 16931. No printing programs, SmartForms, or SAPScript customizations are necessary.
In six weeks. A pure CBCS introduction is live in 4–6 weeks, a CICS introduction in 3–4 weeks. Both in parallel is realistically productive in 6–8 weeks—depending on templates and recipient requirements.
