E-Invoicing Integration for SAP
REST API-based Peppol and ZATCA e-invoicing for SAP S/4HANA and Business One — IDoc compatible, AI-validated, zero kernel changes.
InvoStaq for SAP connects to your SAP environment via a clean REST API. Invoice data flows from S/4HANA or Business One to InvoStaq's AI validation engine, which checks every document against country-specific e-invoicing rules in under 200 milliseconds — then dispatches compliant invoices to the Peppol network or ZATCA portal.
Unlike traditional SAP add-ons that require ABAP development and transport requests, InvoStaq operates entirely outside the SAP kernel. Your Basis team keeps a clean system, your finance team gets automated compliance, and your invoices reach recipients faster.
Why SAP Teams Choose InvoStaq
API-first architecture that respects SAP best practices — no add-ons, no transports, no risk.
REST API Integration
InvoStaq connects to SAP via a clean REST API — no ABAP add-ons, no transport requests, no kernel modifications. Your SAP Basis team will approve it in minutes.
S/4HANA & Business One
Supports both SAP S/4HANA (on-premise and cloud) and SAP Business One. One integration pattern, two SAP platforms, full compliance coverage.
IDoc & BAPI Compatible
Extract invoice data via IDoc outbound processing or BAPI calls. InvoStaq consumes standard SAP invoice structures — no custom function modules required.
AI Validation Engine
The same AI engine that powers our D365 and Odoo plugins validates every SAP invoice in under 200ms — catching tax-code errors, formatting issues, and compliance gaps before submission.
From SAP to Compliant Invoice in Four Steps
A standard integration your SAP Basis and ABAP teams will recognise — using patterns they already know.
Connect via REST API
Configure an RFC destination or HTTP connection in SAP to call InvoStaq's REST endpoints. We provide Postman collections and SAP-specific integration guides.
Map Invoice Fields
InvoStaq auto-maps standard SAP invoice fields (BKPF/BSEG for FI, VBRK/VBRP for SD). Custom fields can be mapped through our configuration UI — no ABAP needed.
AI Validates Every Invoice
When an invoice is posted in SAP, the integration sends it to InvoStaq for real-time AI validation. Results are returned with a traffic-light status and plain-English explanations.
Compliant Delivery via Peppol or ZATCA
Valid invoices are dispatched through the Peppol network or ZATCA FATOORA portal. Status updates flow back to SAP so your team has full visibility without switching systems.
SAP-Native Patterns, Cloud-Native Compliance
Built for SAP architects who want e-invoicing without compromising their system landscape.
Zero SAP Kernel Changes
InvoStaq operates entirely outside the SAP kernel. No transports, no ABAP modifications, no impact on your support stack or upgrade path. Your SAP system stays clean.
IDoc Outbound Processing
Leverage SAP's native IDoc framework (INVOIC01/INVOIC02) to send invoice data to InvoStaq. Existing IDoc configurations and partner profiles can be reused.
Multi-Company & Multi-Plant
Handle multiple company codes, plants, and sales organisations from a single InvoStaq instance. Per-entity Peppol participant IDs and country rules are configured centrally.
Real-Time & Batch Modes
Send invoices in real time as they're posted, or batch them via scheduled jobs. InvoStaq's API supports both patterns with the same validation guarantees.
Supported E-Invoicing Standards
One API, five standards — InvoStaq routes each invoice to the correct format and network based on the recipient's jurisdiction.
Peppol BIS 3.0
Pan-European and Australian e-invoicing standard
ZATCA FATOORA
Saudi Arabia Phase-2 e-invoicing and clearance
EN 16931

It supports IDoc outbound processing and BAPI calls, requires zero ABAP modifications or SAP kernel changes, and handles multi-company, multi-plant configurations — giving SAP teams automated e-invoicing compliance through familiar integration patterns.
