Independent total cost of ownership modelling across brownfield S/4HANA, RISE with SAP Cloud Private Edition, and hybrid scenarios. Built by buyer side analysts, audited by buyer finance, owned by the buyer organisation. No SAP fees. No hyperscaler kickbacks. No reseller spreadsheets.
SAP account teams typically present a three year TCO model that compares RISE with a stylised on premise baseline. The model is short. The baseline is favourable to the RISE conclusion. The cost lines that hurt RISE most, such as overage charges in years five through seven, FUE growth assumptions, hyperscaler reserved capacity gaps, and exit transition costs, are either excluded or rolled into a single line called "operational".
The result is a deck that looks decisive but underprices RISE by between twenty and forty percent across the seven year horizon. Boards approve on the deck. Three years later, the year four true up arrives. By then the migration is complete, the brownfield estate is decommissioned, and the leverage to renegotiate is gone.
The buyer side answer is a parallel TCO model, owned by the buyer, built to a seven year horizon, with the cost lines SAP excludes brought back into the comparison. That is the work this service produces.
Every TCO engagement models three scenarios at minimum, which are brownfield S/4HANA, RISE with SAP Cloud Private Edition, and a hybrid model that keeps the brownfield core for headquarters and runs RISE for new entities or acquired businesses. Each scenario is built across nine cost domains.
Each phase produces a written artefact. The artefacts are owned by the buyer, not the firm. At the end of the engagement, the buyer has a working model they can rerun against future RISE proposals without further engagement.
The deliverable is not a slide deck. It is a working model the buyer organisation owns and can rerun. Side by side comparison of what the seller usually provides against what this engagement produces.

TCO modelling is rarely a standalone purchase. It is the analytical backbone underneath every RISE with SAP negotiation, brownfield comparison, and contract review.
Quarter end campaigns, hyperscaler reserved pricing changes, FUE pricing shifts. Sent when SAP makes a move, not on a schedule.
Our SAP RISE negotiation services run buyer side only. Five hundred engagements behind the bench, sixty eight percent average reduction against the first SAP proposal, and one hundred eighty million dollars in client savings delivered. Each engagement opens with a working session, not a sales pitch.
