Introduction E-Invoicing
|
Receive compliantly. Send efficiently. Scale internationally. E-invoicing has effectively arrived in German B2B since 2025 — and 2026 is the year to turn “we’ll see” into a stable, operational process. For SAP-driven organizations, that means a solution that covers both inbound and outbound, supports formats such as XRechnung and ZUGFeRD, enables transport channels like PEPPOL, and doesn’t turn into a never-ending construction site once it’s live. FINK IT-Solutions supports you end-to-end: from readiness assessment and architecture to implementation, plus managed services, monitoring, and continuous compliance maintenance — SAP-close, scalable, and audit-ready. Beyond Germany: FINK IT-Solutions supports more than just German e-invoicing requirements. We enable and operate global e-invoicing standards in SAP — covering country-specific formats, transport networks, and compliance rules worldwide, tailored to your business footprint.

E-invoicing in 2026: What matters now
Many companies “somehow” ensured receipt in 2025 — often via shared mailboxes, portals, or isolated workarounds. The issue: without validation, exception handling, and proper archiving, e-invoicing becomes expensive in daily operations.
2026 is the right time to properly establish three things:
- Inbound receipt & processing: structured, validated, with clear ownership
- Outbound sending: scalable, format-capable, channel-agnostic
- Compliance operations: monitoring, updates, audit trail, audit-ready retention
If you operate internationally, add this: country requirements change continuously — e-invoicing is no longer a “Germany-only” topic.
Formats & standards in Germany: XRechnung, ZUGFeRD, PEPPOL
XRechnung is a structured XML format, widely used in the public sector (B2G), with strict mandatory fields and validations (e.g., “Leitweg-ID” in public-sector contexts).
ZUGFeRD is a hybrid format (PDF + embedded XML). It’s popular in B2B because it remains human-readable — but the structured XML data is what matters for automated processing and compliance.
PEPPOL is an established transport mechanism via defined networks/access points — especially relevant if you want to transmit invoices standardized, secure, and internationally interoperable.
Important for SAP: format and transport are two separate decisions. A robust solution supports both — without your team having to “rebuild” each combination manually.
E-invoicing with SAP: What a stable process looks like
A SAP-ready e-invoicing flow consists of a few critical building blocks:
- Receipt via channel (PEPPOL, email, portal, interface)
- Validation & format checks
- Transfer into SAP (FI/MM)
- Workflow/approval (if required)
- Posting + audit-ready archiving incl. logs/protocols
- Invoice creation in SAP (incl. country/customer-specific fields)
- Transformation to target format (e.g., XRechnung, ZUGFeRD)
- Validation (technical + business rules)
- Signature/sending via channel (PEPPOL, email, portal, AS2, …)
- Status tracking, feedback handling, error processing, archiving
Our goal: You can see at any time in your SAP environment where an invoice is stuck, why it’s stuck — and how to return it cleanly into the process.
Typical challenges in SAP landscapes
Across projects we repeatedly see the same obstacles — especially in mature, complex environments:
- Master data gaps (IDs, references, addresses, VAT logic, mandatory fields)
- Multiple SAP systems (ECC + S/4 + SAP Cloud ERP private/public) without central governance
- Many edge cases (credit notes, partial invoices, corrections, deviations)
- Oerations without monitoring → high manual workload day-to-day
- Archiving not designed end-to-end (format data + evidence + audit trail)
That’s why we focus on SAP-close standards and operational excellence — not “interface done, project over”.
Our services: From assessment to managed service
- Readiness check (countries, volumes, scope, criticality)
- Architecture check (SAP/non-SAP, integration & standardization potential)
- Process & risk analysis (interfaces, exceptions, compliance risks)
- Licensing & operating cost model (make/buy, managed service options)
- Target picture for e-invoicing & tax compliance (B2B/B2G/international)
- Integration design (SAP DRC, OpenText VIM, SAP BTP / Integration Suite)
- Roadmap & rollout plan (quick wins + scalable expansion)
- Implementation based on SAP DRC (and, if required, platform/network connectivity)
- Automation of inbound invoice processing (validate, approve, post)
- Connection of external channels/platforms (e.g., PEPPOL, portals, country routes)
- “Lean invoice” approach: fewer manual steps, higher throughput
- SLA-based operations, monitoring, incident & change management
- Cost and license optimization in the e-invoicing context
- Governance, security, audit trail, audit-ready retention
- Future-proof e-invoicing architecture with a clear roadmap
- Less manual work through automation (inbound/outbound)
- Compliance confidence through validation, traceability, and an operational model
- Reduced burden on your IT team through managed services & monitoring
- Flexible target architecture: SAP DRC + OpenText VIM + optional third-party components
Solutions: SAP DRC & OpenText VIM
SAP DRC is the compliance backbone in the SAP world: e-invoicing, formats, validation, transmission, monitoring — and (depending on the country) regulatory/tax reporting. Ideal if you want to scale internationally or plan for evolving EU requirements.
OpenText VIM strengthens accounts payable: capture, verification, workflows, transparency — including archive integration. Combined with SAP DRC, it creates an end-to-end chain from receipt to payment.

FAQ
An e-invoice is an invoice in a structured, machine-readable format that enables automated electronic processing (not just a PDF).
XRechnung is a structured XML format, mainly used in the public sector, with defined mandatory fields and validations.
ZUGFeRD combines PDF + XML. It’s often used in B2B when you want automated processing plus a human-readable PDF representation.
PEPPOL is an established transport framework via standardized networks/access points. It’s useful if you want to transmit invoices standardized and internationally interoperable.
Not necessarily — but for many SAP organizations, SAP DRC is the cleanest way to implement e-invoicing SAP-close, scalable, and with centralized monitoring. Depending on countries, volumes, and IT strategy, platform/third-party integration can also make sense.
