WHERE WE HELP
The problems we are usually called in to solve.
SAP ECC mainstream maintenance ends in 2027, with paid extended support to 2030. Most teams know where they want to go — the risk sits in the custom logic, interfaces and data they have to bring along.
Our systems don’t agree.
ECC INTEGRATION
Real-time BAPI/RFC, IDoc and EDI interfaces so prices, inventory and orders match across SAP, web shops and partner systems.
Migration data is the part that scares us.
DATA MIGRATION
Extraction, mapping and validation into S/4HANA migration templates, with repeatable loads through cutover.
The integrator says green. We’re not sure.
SAP OVERSIGHT
PMP-led, client-side verification of scope, risks and go-live readiness. How it works →
Need extra hands? Senior specialists join your team for a defined scope — Basis, ABAP/Fiori, Integration, PP/QM, BW/BO.
SAP OVERSIGHT
An experienced SAP voice on your side of the table.
Led by Wolfgang Niefert, PMP, with PMP-certified SAP consultants. We work for you, not the integrator — verifying what status reports say before it shows up in cost, scope or the go-live date.
- Scope & change requestsWhat was promised, what changed and what it costs
- Integrator deliverablesStatus checked against evidence, not slides
- Risks, issues & decisionsOwned, dated and visible to leadership
- Data migration & testingLoad results and defects that support go-live
- Cutover readinessA clear go / no-go view before the weekend that matters
- RecoveryA practical reset plan when a program slips
