EPO Consulting

What EPO Consulting does

EPO Consulting GmbH is a privately held Austrian software vendor, headquartered in Vienna and founded in 2003, that develops ABAP-based add-ons, e-invoicing solutions, and mobile applications for SAP ERP and SAP S/4HANA environments. The company's flagship product, the EPO Connector, is a SAP-certified ABAP add-on (certified since 2005, re-certified for SAP S/4HANA in March 2021) that exposes JSON REST APIs from SAP to non-SAP systems without requiring SAP PI/PO middleware, giving access to 360,000+ SAP function modules across an unchanged 15+ year code base. Building on this integration layer, EPO Consulting has assembled a broader portfolio spanning electronic invoicing (Create & Send, Receipt, Viewer, Validator, Intercompany, Incoming Document Handling Server for XRechnung, ZUGFeRD, UBL XML, FatturaPA, ebInterface, and PEPPOL), mobile applications for plant maintenance, approval workflows, and warehouse/asset inventory, and utility add-ons (IDoc Monitor, UID Check, EPO Suche, EPO Direct Link).

The company serves SAP operators across healthcare, manufacturing, automotive, wholesale, public sector, and transportation, with named customers including ÖAMTC, Tirol Kliniken, Würth, Schmolz+Bickenbach, Bundesimmobilien, ASFiNAG, and Leitner Ropeways. Revenue is generated through a mix of per-license SAP add-on subscriptions (EPO Connector, mobile apps, UID Check, IDoc Monitor), professional services for implementation and custom ABAP development, and tiered SaaS subscriptions for the E-Rechnung Viewer (€0–€180/month). Go-to-market is consultative direct enterprise sales augmented by a partner channel that includes SAP AG (ecosystem/S/4HANA Cloud), smahrt consulting AG (Switzerland reseller with 50+ installs of the smahrt-ELM Connector built on EPO Connector), ecosio GmbH (PEPPOL infrastructure), and Open7 Communication GmbH (co-development of the Viewer app). The team of 5 employees, led by Managing Director Werner Kroiss (28+ years SAP experience) and Sales Manager Manfred Trojan, supports operations across Austria, Germany, Switzerland, Italy, France, the Netherlands, and Poland via a multilingual website. No external funding, M&A activity, or ownership changes are disclosed.

Revenue model

1. SAP Add-on Software Licenses and Subscriptions: EPO Consulting sells its software products (EPO Connector, EPO e-Invoicing, EPO Mobile Apps, EPO UID Check, EPO IDoc Monitor, EPO Suche/AFS) as SAP add-ons. These are deployed within SAP systems and sold as licenses, typically with ongoing maintenance and support. The company references "überschaubare Kosten durch geringe Lizenzgebühr" (manageable costs through low license fees) for the EPO Connector, indicating a per-license or per-deployment pricing model. Implementation services, training, and configuration are provided alongside the software.
2. Professional Services and Implementation: The company provides implementation, configuration, and consulting services for its SAP add-ons and customer projects. Services include agile development collaboration with customers, custom ABAP developments, and training sessions. These are likely sold as professional services engagements, often embedded in the initial sales cycle of the software.
3. E-Rechnung Viewer SaaS Subscriptions: The EPO E-Rechnung Viewer is offered as a cloud/SaaS product with tiered monthly subscriptions (Free, Premium at €29–180/month depending on volume), plus optional XML Validator add-ons (€20–120/month). The viewer also has a premium REST API version for automated workflows, indicating a usage-tiered subscription model.

Direct peers

• Vertex Inc: Vertex provides SAP-certified tax compliance, e-invoicing, and VAT determination solutions, competing directly with EPO's UID Check and e-Invoicing suite. Both target SAP ERP/S/4HANA customers needing cross-border tax and e-invoicing compliance.
• Serrala: Serrala (formerly Hanse Orga) provides SAP-integrated financial automation, including invoice processing, payment, and treasury solutions. It overlaps with EPO's e-Invoice Receipt and SAP-integrated invoicing workflows for mid-market and enterprise SAP customers.
• inPuncto GmbH: inPuncto provides integrated SAP Document Management System (DMS) and invoice archiving solutions with deep SAP ERP/S/4HANA integration. It is both a listed EPO Consulting partner and a partial competitor in the SAP document/invoicing handling space, particularly around incoming document processing.
• SEEBURGER: SEEBURGER is a German-headquartered provider of SAP integration, EDI, and B2B/PEPPOL solutions, directly competing with EPO's Connector and e-Invoicing products. Both target SAP ERP/S/4HANA customers needing middleware-free or hybrid integration, with SEEBURGER offering a broader enterprise-grade platform.
• Sovos: Sovos is a global leader in tax compliance and e-invoicing, with deep SAP integration through the Sovos VAT Compliance and e-Invoicing suites. It directly competes with EPO's XRechnung/PEPPOL/FatturaPA compliance offerings, particularly for multinational customers needing cross-border mandates beyond DACH.
• ecosio GmbH: ecosio is an Austrian-based SAP EDI and PEPPOL integration specialist with very similar product-market fit to EPO Consulting. Both sell SAP add-ons for electronic invoicing and B2B/EDI integration; ecosio is also a listed EPO Consulting partner, making it both a competitor in some accounts and a complement in others (ecosio provides PEPPOL network infrastructure that pairs with EPO's e-invoicing modules).
• Lobster_data: Lobster_data is a German provider of no-code/middleware integration, EDI, and API solutions with strong SAP ERP/S/4HANA integration focus. It competes with EPO Connector on SAP-to-non-SAP integration without traditional middleware, serving similar DACH enterprise customers.
• Crossinx (now part of Coupa): Crossinx was a European PEPPOL network operator and SAP-integrated e-invoicing platform competing with EPO on XRechnung, PEPPOL, and B2B electronic invoice compliance before being acquired by Coupa. Listed here as a historical direct peer shaping the market dynamics EPO competes in.
• Pagero: Pagero (now part of Thomson Reuters) is a leading PEPPOL network and e-invoicing compliance provider competing with EPO's PEPPOL/XRechnung/FatturaPA capabilities. Both serve enterprises needing structured electronic invoice exchange across European mandates.

Emerging players

• smahrt consulting AG: smahrt consulting AG is a Swiss SAP consulting partner that builds the smahrt-ELM Connector on top of EPO's technology, having delivered 50+ installations for Swiss payroll reporting. While not a direct head-to-head competitor, it represents an emerging channel partner pattern that could be emulated — or could itself evolve into a more independent competitor in Switzerland.
