Slenderiser holds SAP Silver Partner status.

The business model is 100% professional services, delivered via customer-individual (kundenindividuell) solutions priced on a quote basis with multi-year contracts. Customer acquisition runs through direct, consultative sales anchored by senior relationship managers (Christian Wodtke for careers, Peter Sikora for software).

Closest large-scale peer to Slenderiser in terms of SAP specialization, target customers, and partner tier dynamics.

• cbs Corporate Business Solutions: Global SAP S/4HANA, manufacturing, and supply chain consultancy with strong roots in the German Mittelstand. Directly comparable as a mid-sized SAP pure-play focusing on industrial and process-manufacturing clients, competing with Slenderiser for S/4HANA E2E projects.
• All for One Group: German-headquartered SAP consulting and managed services firm serving mid-market customers with SAP S/4HANA, ERP, and supply chain implementations. Directly comparable as a mid-sized, DACH-focused SAP partner competing for the same E2E supply chain transformation projects as Slenderiser.
