Why three year TCO models miss the real cost of RISE.

The three year TCO comparison is the most popular slide in the RISE sales motion. It is short, intuitive, and easy for a CFO to absorb. It also produces the wrong answer. RISE is a seven year commitment for almost every buyer that signs it, with uplift clauses, growing Digital Access volumes, BTP overage trajectories, and renewal dynamics that all sit beyond year three. A three year model captures only the introductory pricing window and misses the period in which the real cost emerges. This article walks through why the three year horizon is the wrong frame, what the seven year horizon surfaces that the three year horizon hides, and how to rebuild the comparison so the board sees the full commitment rather than the opening offer.

The three year framing is a sales artefact, not a commercial reality

The three year framing originated in the early SaaS sales cycle, when annual subscriptions were the dominant pricing instrument and three years was the longest term most buyers would accept. RISE is not a three year subscription. It is a seven year contract in its standard form, with a renewal that often runs to a further five years. The pricing inside RISE is structured around the seven year horizon, with year one priced below cost recovery, year three priced at the par level, and years four through seven priced to deliver the lifetime margin SAP requires.

The three year model captures the discounted years and treats the resulting average as the standing cost of the platform. The treatment is wrong on two counts. The discount is not standing. It is amortised against a longer commitment. The model that uses only the discounted years overstates the value of the discount and understates the cost of the commitment that produced it.

The buyer that reads the three year model as a fair representation of cost is, in effect, looking at a freight train from the front and concluding it is a small object. The shape of the train is only visible from the side. The seven year model is the side view.

What sits inside years four through seven that years one through three do not show

The uplift mechanism is the most obvious omission. A RISE contract carries an annual uplift clause, typically indexed to an inflation benchmark, with a floor that rarely sits below two and a half per cent and a ceiling that rarely sits below five per cent. The uplift is dormant in year one and rarely triggers in year two. By year four, the compounded uplift adds nine to twelve per cent to the invoice. By year seven, the compounded uplift adds 22 to 31 per cent. The three year model assumes the price stays flat. It does not.

BTP overage is the second omission. The BTP allocation inside the bundle is sized for a baseline integration scope. By year three, the allocation is typically depleted on real workloads. From year four onwards, the buyer pays for BTP consumption at the contracted overage rate, which is often three to four times the bundled rate per unit. The cost line grows through years four to seven as integration estate matures.

Digital Access volume is the third omission. The Digital Access count at signature is sized against the current document load. By year four, the count has typically grown by between 40 and 70 per cent, driven by EDI expansion, API growth, and integration with newly acquired entities. The true up cost lands in years four through seven and is not visible in the three year view.

The renewal exposure is the fourth omission. The renewal negotiation begins in year six and resolves in year seven. The buyer that has not modelled the renewal exposure enters the negotiation without a fallback position. The cost of the missing fallback is visible only when the renewal pricing arrives, which is past the three year horizon.

How the discount profile actually works

The discount on a RISE proposal is rarely uniform across the term. The proposal typically carries a heavy year one discount, a tapering year two discount, a par year three rate, and a list price progression from year four onwards. The discount profile is a sales mechanism that produces a strong opening number, a strong three year average, and a back loaded cost recovery for SAP.

The buyer that models only the first three years sees the average of the discounted period. The buyer that models the full seven years sees the trajectory. The trajectory is what governs the real cost. A 22 per cent discount on the three year average can resolve to a 9 per cent discount on the seven year average once the uplift and the list price progression are applied.

The accurate framing for the board is the seven year discount, not the three year discount. The seven year discount is rarely flattering. It is, however, accurate, and the accuracy is what allows the negotiation to target the structural levers rather than the headline.

Cash flow versus cost: why the three year view is doubly misleading

The three year model conflates cash outlay with cost. The two are not the same. A RISE contract that runs to seven years carries a contractual commitment to pay for all seven years, regardless of whether the buyer uses the platform across the full term. The cost is the present value of the seven year commitment. The cash outlay in years one through three is a fraction of the cost.

A workable buyer TCO model carries two views. The first view is the year by year cash outlay across the seven year term. The second view is the discounted present value of the full commitment, calculated against the buyer's cost of capital. The two views together give the board the full picture: what is paid in each year, and what is committed in total.

The three year model carries neither view correctly. It shows the cash outlay for three years and presents the result as the cost of the platform. The presentation is misleading by construction. The board approval that rests on the presentation is an approval of less than half the real commitment.

What the seven year model surfaces that the three year model hides

The seven year model surfaces five quantities the three year model hides. The first is the cumulative uplift across the term, which on a typical mid sized deal runs to four to eight million dollars. The second is the BTP overage trajectory, which runs to three to seven million dollars. The third is the Digital Access true up, which runs to one to three million dollars. The fourth is the renewal exposure, which is rarely sized below five per cent of the original contract value. The fifth is the cost of the internal team that runs RISE across the full term, which is typically eight to fourteen full time equivalents loaded by overhead.

The five quantities together usually amount to between 28 and 41 per cent of the contract value above what the three year view shows. On a 25 million dollar RISE proposal, the gap is seven to ten million dollars. The gap is not a small variance. It is the difference between a decision the board can defend and a decision the board will be asked to explain.

How to talk to a CFO who wants the three year number

The CFO who asks for the three year number is usually asking out of habit rather than out of conviction. The habit is rooted in the older SaaS cycle and in the comfort of a shorter horizon. The right response is not to refuse the three year number. The right response is to provide it alongside the seven year number, with the gap explained clearly and in dollars.

A workable presentation runs three columns. The first column shows the three year TCO. The second column shows the seven year TCO. The third column shows the gap, broken into the five categories above. The CFO who sees the columns understands the trade off immediately. The CFO who sees only the three year number does not.

The board approval that follows the three column view is an informed approval. The board approval that follows the single column view is a hopeful approval. The difference compounds across the term in the same way the uplift compounds across the invoice.

Conclusion: the right horizon is the contracted horizon

The right TCO horizon for a RISE contract is the horizon of the contract itself. The three year view captures the discounted introductory window and misses the period in which the real cost emerges. The seven year view captures the full uplift, the BTP overage, the Digital Access growth, the renewal exposure, and the internal team cost. The gap between the two views is rarely below 28 per cent and is often above 40 per cent. The board that approves a RISE deal on the three year view is approving less than half of what it is committing to. The board that approves on the seven year view is approving the full commitment. The work of the buyer side TCO model is to make the second approval possible.
