About us

Everyone promises reliability.We let our clients speak.

We do one thing: OpenText Vendor Invoice Management for SAP Solutions (VIM) — SAP VIM for short. Johannes Auer spent almost six years in the professional services team at OpenText delivering VIM projects before founding this company. He knows VIM from the inside, not from reading about it.

What we measure ourselves against: not the go-live, but the everyday after it — invoice intake that simply runs. What we do to get there is on this page. Why clients stay, they tell you themselves just below.

Direct accountability. Selectively reinforced when needed. Hire us and you get Johannes Auer himself — from the first call into everyday operation. Architecture, functional leadership and quality stay with him. When scope grows, a proven circle of experienced SAP VIM consultants across Europe, the Americas and Australia joins in — each with a clearly agreed role before they start.

Customer voices

What clients say

  • Johannes Auer impresses across the board with his overall package as a project manager. His ability to address issues early and proactively, combined with an excellent professional background, builds trust from the very beginning. Particularly noteworthy is his clear, technically sound, and at the same time pleasantly human communication with all stakeholders, which significantly contributes to the project’s success. Even in challenging situations, he remains calm and keeps a clear overview. His structured way of working and his ability to explain even complex matters in a clear and precise manner round off his profile and make working with him not only successful but also highly enjoyable.1

  • Johannes is incredibly patient, always willing to share his knowledge, and quick to respond and organize calls. He tackles every challenge proactively and supports the entire team with dedication and care. Working with him is truly a pleasure.

    Arleta Lipka

    Internal Consultant · SAP FI/CO

  • Johannes supported us during our migration from SAP R/3 to SAP S/4 HANA, including the upgrade of OpenText Vendor Invoice Management for SAP Solutions (VIM) which we are using to process sales orders. We were facing several uncertainties in the process, as well as issues with SAP Single Sign-On in the validation client.

    Thanks to his clear guidance and deep technical expertise, we were able to complete the upgrade successfully and identify the root cause of the SSO issue. Johannes even uncovered a deeply rooted bug in the OpenText Intelligent Capture for SAP Solutions (IC4S) component related to restoring machine learning data, which we were able to get corrected. His ability to explain complex topics clearly and his professional, solution-oriented approach made a big difference for us.

    I would absolutely recommend working with him.

  • What I particularly value in working with Johannes Auer is his quick grasp of complex topics and his extensive expertise – not only in the SAP VIM environment but also across the broader SAP landscape.

    He finds pragmatic solutions, critically questions existing processes, and proactively provides helpful documentation. He delivers changes and adjustments reliably after conducting his own tests – significantly reducing the risk of errors only being discovered by the business users.1

Two deadlines that affect your invoice intake

  • Receiving mandatory since 2025

    The e-invoice

    You have had to be able to receive for a while; issuing follows from 2027. The real question is who does what: the format, the transmission route — and which part your VIM takes on. In Germany plain e-mail is often enough, and SAP DRC is one option among several.

  • Maintenance ending from 2027

    The S/4HANA transformation

    Public or private edition, RISE or self-operated: the choice of operating model helps decide whether your invoice intake moves along or needs a new target picture. Steering committees regularly ask this question too late.

SAP VIM knowledge

SAP VIM consulting: OpenText Vendor Invoice Management for SAP

Johannes Auer IT Consulting GmbH is a consultancy specializing in OpenText Vendor Invoice Management for SAP Solutions (SAP VIM). We implement, optimize and support automated invoice processing in SAP ERP and SAP S/4HANA — from the first assessment through customizing and development to worldwide rollouts and day-to-day operations.

What is SAP VIM?

OpenText Vendor Invoice Management for SAP Solutions — SAP VIM for short, also known as SAP Invoice Management by OpenText — automates the processing of incoming vendor invoices directly inside SAP. Business rules check every document automatically, workflows route approvals and exceptions, and accounts payable can see the status of every invoice at any time. Implemented well, VIM shortens cycle times, removes manual checks and makes incoming invoice processing audit-proof.

E-invoicing: XRechnung, ZUGFeRD, Peppol and KSeF

Electronic invoicing is becoming a legal requirement in more and more countries. We set up XRechnung and ZUGFeRD processing for Germany, integrate SAP VIM with SAP Document and Reporting Compliance (DRC) for Peppol e-invoices — for example in Belgium — and connect national platforms such as Poland's KSeF (Krajowy System e-Faktur) or the French e-invoicing mandate. How SAP DRC and VIM divide the work is explained on our page about e-invoicing, SAP DRC and VIM; which country switches on which stage when is listed in the country overview.

Document capture with IC4S and CC4S

OpenText Intelligent Capture for SAP Solutions (IC4S) and Core Capture for SAP Solutions (CC4S) extract invoices and other documents automatically. We configure extraction and validation and tune the learning behaviour of the recognition so that as many documents as possible post without any manual touch. With AIxVIM we add modern AI extraction directly to the VIM inbound process.

VIM Beyond Invoices: more than invoices

The VIM Beyond framework (formerly Business Center) also handles sales orders, order confirmations and fully custom document types. We design solution packages, implement data enrichments, business rules and approval workflows, and support the rollout — see our project list for examples.

Consulting, development, support and training

Whether it is a new VIM implementation, a version upgrade or an S/4HANA transformation: we take on project management, customizing and ABAP development in SAP VIM consulting, provide 3rd-level support in daily operations and train key users and internal IT — including online training. Where you stand today is what the fixed-price SAP VIM Executive Diagnostic establishes; keeping it that way is what SAP VIM Continuous Optimization is for. We publish hands-on guides from real projects on our SAP VIM blog. Or simply book a free 30-minute call.
