Most CIOs running SAP ECC are not asking whether to migrate to S/4HANA. They are asking how to pay for it without a budget increase they cannot get approved this year. Third-party SAP support is one of the few levers that generates that funding directly from an existing line item, rather than requiring a new one.

The 2027 deadline is real, and most organizations are behind it

Mainstream SAP maintenance for ECC ends December 31, 2027. There is no signal of a further extension. For organizations that stay on unsupported ECC past that date, the exposure is not abstract: no new security patches, no compliance updates, and no official fixes for a system that likely still runs core finance, supply chain, or HR processes.

If that sounds like a problem other companies have already solved, the numbers say otherwise. At the end of 2024, only 39%, or about 14,000, of the 35,000 SAP ECC customers had migrated to S/4HANA, according to Gartner. The majority of the SAP installed base is in the same position: aware of the deadline, not yet moving.

That is not a reason to relax. It is a reason to find funding for migration now, before the last-minute compression drives up cost and risk for everyone still waiting.

What third-party SAP support actually changes on your P&L

The mechanics are straightforward. You stop paying SAP for mainstream maintenance on your ECC system and move that support to a third-party provider at a lower annual rate, while your system keeps running as-is.

The savings are documented, not promotional. Independent estimates put ongoing reductions in the 50–60% range on annual support spend, with cumulative five-year savings from switching reported to exceed 60% of total support cost after accounting for SAP's typical annual price increases. Standard SAP support already runs around 20% of license fees and climbs 2–4% a year on its own, so the baseline cost you are cutting from is not static either. It goes up every year you do nothing.

None of this requires touching your ECC environment. Third-party support maintains the system as it stands. It does not replace migration planning, and it should not be sold to you as a substitute for one.

The funding gap: two options isn't the full picture

Most CIOs frame the 2027 decision as binary: migrate now, or delay and accept the risk. Industry content on third-party support reinforces this by treating the switch and the migration as separate, parallel tracks with no connection between them.

That framing leaves money on the table. The support-cost reduction third-party support delivers is not just a cost avoidance. It is a recurring, multi-year cash release that can be earmarked, tracked, and applied directly against a future migration budget line, rather than absorbed into general IT spend where it disappears.

The distinction matters at the CFO level. A savings number with no destination reads as a cost-cutting initiative. A savings number earmarked against a named migration budget reads as a funded transformation plan. The second version gets board approval faster.

Structuring the savings into a migration fund

This works when it is designed deliberately, not left to chance. Three questions determine whether it functions as a funding mechanism or just evaporates into the budget:

  • Where does the savings go? Set up a dedicated migration reserve line at the point you sign the third-party support contract, before the first savings shows up on a statement.
  • What is the time horizon? Match the third-party support term to your realistic migration runway. Migrations of this scale commonly span 18 to 36 months once started, so a two-to-three-year bridge is a reasonable starting point for most mid-market and enterprise environments, calibrated to your own systems and integration complexity.
  • What resets the clock? Exit terms matter more than entry price. Some providers apply reinstatement fees or back-maintenance charges if you return to SAP support outside a greenfield RISE re-entry. Know that cost before you sign, not after.

Get these three answers in writing before committing budget assumptions to a board deck.

Where this fits with your broader S/4HANA roadmap

Third-party support is a bridge, not a destination. It buys planning time and migration capital. It does not replace the technical and organizational work of the migration itself: landscape assessment, Clean Core alignment, custom code remediation, integration re-architecture, and the change management that determines whether the new system actually gets adopted.

ITChamps works with organizations across this full arc, as an SAP Gold Partner delivering both 3PS Advisory to structure the support transition and S/4HANA Migration services to execute the move once the funding and timeline are set. The two are designed to connect: the savings model built during the advisory phase feeds directly into the migration scope and sequencing that follows.

The bottom line

Third-party SAP support will not make your 2027 deadline disappear. What it does is convert a cost you are already paying into capital you can point at a specific migration date, with a documented plan for how the money gets there and what it will fund. Organizations that structure it that way go into their board conversation with a funded roadmap. Organizations that treat it as a generic cost cut go in with a savings number and no plan attached, which is the version that gets questioned in the room.

The distinction is not the switch. It is what you do with the fifteen to twenty percent of your IT budget that switch frees up.

Frequently Asked Questions

Does switching to third-party SAP support delay my S/4HANA migration? 

Not by itself. Third-party support maintains your existing ECC environment; it does not replace migration planning. Whether it delays your migration depends on how you use the freed budget and time. Structured correctly, it accelerates the migration by funding it sooner.

Can I go back to SAP support after switching to a third-party provider? 

Reinstatement is generally possible but often comes with back-maintenance charges and reinstatement fees for the period you were outside SAP's support. Terms vary by provider and by whether you re-enter as a greenfield RISE with SAP customer. Confirm exit terms before signing, not after.

How much can third-party SAP support actually save on our budget? 

Reported ranges across independent sources run 50–60% on annual support fees, with higher cumulative savings over a five-year term once SAP's typical annual maintenance increases are factored in. Actual savings depend on your current contract, system complexity, and provider terms.

Is third-party support only for companies that aren't migrating at all? 

No. It is used both by organizations delaying migration indefinitely and by organizations using the interim savings specifically to fund a planned S/4HANA migration. The strategy described here applies to the second group.

What does ITChamps do differently from a pure third-party support vendor? 

combines 3PS Advisory with S/4HANA Migration delivery as an SAP Gold Partner, so the savings structure built during the support transition is designed from the outset to feed a defined migration plan, rather than operating as two disconnected engagements.
