Moving from SAP ECC to S/4HANA is not just a technology migration — it is the largest commercial reset SAP will ever attempt on your account. SAP uses the migration to expand your license scope, restructure your user types, and lock you into multi-year commitments before you have independently validated what you actually need. With independent BOM review, license conversion advisory, and negotiation support, organizations consistently reduce S/4HANA migration costs by 30 to 45% against SAP's opening proposal.
SAP ECC mainstream maintenance ends in 2027, with extended maintenance options running to 2030. Every SAP ECC customer is facing a migration decision — and SAP's account teams are using that deadline as the primary sales lever to drive RISE with SAP and S/4HANA commitments. SAP's urgency framing is real but carefully managed: the timeline pressure is genuine, but the commercial terms SAP presents as non-negotiable are not.
The core commercial risk is SAP's Bill of Materials (BOM). SAP's migration proposals routinely include license types, modules, and user counts that are larger than your actual requirements. The S/4HANA user type model is fundamentally different from ECC — and the conversion methodology SAP applies to translate your existing ECC users into new S/4HANA named users almost always results in a larger, more expensive license package than a properly constructed BOM would require. We have yet to see an SAP S/4HANA or RISE proposal that could not be materially reduced through independent BOM analysis.
Additionally, organizations migrating to S/4HANA must address any unresolved digital access exposure before migration. SAP routinely uses the migration event to surface indirect access liabilities and bundle their resolution into the S/4HANA commercial package — at maximum value. Independent advisory ensures these conversations are separated and each issue is addressed on its own commercial merits.
We conduct a comprehensive review of your current SAP ECC license inventory, user base, active modules, and system usage data. We map your current commercial position — including any unresolved compliance or digital access items — and analyze SAP's S/4HANA or RISE proposal in detail. We identify every line item in the BOM, every user type conversion assumption, and every professional services estimate that requires independent validation.
This is the highest-value step in the process. Using your actual usage data and the S/4HANA licensing rules, we construct an independently derived BOM that reflects your real requirements — not SAP's commercial optimization. We identify user types that SAP has overclassified, modules included in the proposal that you do not use or need, and professional services line items that are inflated against market benchmarks. The gap between SAP's proposed BOM and an independently constructed BOM typically ranges from 25 to 45% of total deal value. Example: a manufacturing enterprise received a RISE proposal for $18.2M over 5 years. Our independent BOM analysis reduced the required license scope by 31% and benchmarked professional services at $2.1M below SAP's estimate — delivering a total cost reduction of $7.8M.
We build a comprehensive negotiation strategy covering the BOM reduction, the professional services benchmarks, the transition period commercial terms (ECC support during migration), the contract flexibility provisions, and the contract negotiation levers specific to S/4HANA and RISE deals. We prepare your team with counter-proposals, talking points, and guidance on managing SAP's response to each challenged item.
We provide active advisory throughout the negotiation — reviewing SAP's counter-proposals, advising on which positions to hold and which to trade, identifying contract terms that require modification before signature, and conducting final contract review. Our engagement does not end when the commercial terms are agreed. We review the final contract for operational clauses — including audit rights, change of control provisions, and S/4HANA usage measurement definitions — that can create post-signature commercial risk if not addressed.
SAP has presented a migration proposal and the BOM and pricing have not been independently reviewed before commercial negotiation begins.
The S/4HANA or RISE commercial commitment is a material IT capital or operating expense decision that requires independent validation of total cost of ownership.
Still on SAP ECC and facing SAP account team pressure to commit to S/4HANA or RISE before fully evaluating commercial options and alternatives.
Already in S/4HANA or RISE negotiations and need independent BOM analysis and benchmark data to challenge SAP's current proposal before signature.
Planning S/4HANA migration and need to resolve indirect or digital access liabilities before they are bundled into the migration commercial package by SAP.
Do not accept SAP's BOM without independent review. In our experience, every S/4HANA and RISE proposal contains material over-specification. We will benchmark SAP's proposal against comparable deals, identify the savings opportunity, and deliver a no-obligation business case — before you commit to anything. Most BOM reviews complete within two weeks.
