Section I · The Brief

The brief

The client is a global financial services firm with a sixteen-year SAP estate centred on ECC 6.0, a HANA primary database, and twelve application engines covering treasury, financial supply chain, banking services, and a custom payments hub. The firm had begun an S/4HANA conversion programme eighteen months earlier and was being routed by SAP towards a RISE Private Cloud Edition deployment with a multi-year subscription.

SAP's account team had issued a written conversion proposal in the second quarter, sized at $12.4M annually over a five-year term. The proposal converted the firm's existing 38,000 Named User population and 12 engines into a Full Use Equivalent (FUE) count that the SAP team described as a one-for-one re-mapping. The internal procurement leadership had requested an independent review before signing.

The brief from procurement was narrow: validate the conversion math, validate the engine re-mapping, and identify any optionality in the bill of materials that had been omitted from the proposal. Settlement, if achievable, was a secondary objective.

Section II · The Opening Claim

The opening claim

SAP's opening position broke into three streams. The first was a Named User conversion at a blended FUE ratio of 1.4 ECC users to 1.0 FUE. The second was an engine conversion in which all twelve current engines were carried forward at SAP's published S/4HANA-equivalent metric, with no adjustment for utilisation. The third was a Digital Access estimate based on the firm's self-declared 2024 document volume from a Salesforce integration and two payments-system feeds.

The combined annual value of the three streams was $12.4M, set against a current spend on maintenance and support of approximately $5.7M. The five-year contracted commitment came to $62.0M before any discount, with SAP offering a 22 per cent volume discount conditional on signature inside the quarter.

The proposal also bundled in a Cloud Application Services credit pool that was not, in our review, of demonstrable value to the firm. The credits could only be applied to a defined catalogue of services, and the firm's in-house team and existing GSI partner already delivered most of those services at a lower hourly rate.

Section III · The Defence

The defence

The defence began with a Full Use Equivalent reconstruction. We obtained the firm's S/4HANA conversion guide (the version current at the time of the proposal) and the underlying USMM run that SAP had used to derive the 1.4 blended ratio. The ratio had been applied to the entire user population without distinguishing between Professional and Limited Professional bands. When the conversion was re-run with the correct per-band ratios, the FUE count fell by approximately 18 per cent.

The engine remapping was reconstructed by line item. Of the twelve engines, four had measured consumption below 20 per cent of contracted capacity in each of the prior three measurement cycles. Three engines covered functions that S/4HANA absorbs into the base licence and therefore should have been retired in the conversion, not carried forward at full value. The remaining five had reasonable basis to be carried, but at S/4HANA-equivalent metrics that priced approximately 12 per cent below the SAP-proposed metric.

Section IV · The Settlement

The settlement

Settlement closed at an annual subscription value of $4.8M, signed on a five-year RISE Private Cloud Edition contract with a total contracted commitment of $24.0M. The conversion FUE count was agreed at the rebuilt per-band ratio. The engine entitlement was reduced from twelve to five carried engines, with the three absorbed engines formally retired in the conversion paperwork. A Digital Access bucket was agreed at the corrected document baseline with a 35 per cent volume buffer and a measurement-cap clause valid for the contract term.

Three contract clauses were rewritten as part of the settlement. The audit-rights clause was narrowed to a two-year cycle. The benchmarking clause was activated for years three and four with a written re-pricing right. A settlement-as-release clause was added confirming that no further claim could be raised on the pre-conversion period.

Total elapsed time from receipt of the conversion proposal to signed RISE contract was eighteen weeks. The procurement leadership team booked the saving against the year's capital plan and removed the contingent escalation from the board pack.

Section V · Lessons For Other Estates

Lessons applicable elsewhere

The reductions secured in this matter reflect a combination of contractual leverage, evidentiary discipline, and timing. Buyers running comparable estates can adapt the same playbook with a small number of adjustments. The takeaways below are the ones that travel best.

The conversion proposal was not a conversion. It was a re-baseline. Once we treated it that way, the negotiation moved.
