Every comparison of Rimini Street, Spinnaker Support, and Support Revolution that ranks on page one right now was written by one of those three companies, or by a licensing-advisory firm selling negotiation services on the side. None of them is neutral. If you are a CIO trying to shortlist a third-party SAP support provider, you are reading marketing copy dressed up as analysis.
This is the version without a horse in that race.
Bottom line up front: Rimini Street wins on scale and global reach. Spinnaker wins on white-glove service and contract flexibility. Support Revolution wins on price for smaller, less complex SAP or Oracle estates. All three require you to permanently exit SAP's official support and roadmap - a bigger decision than any vendor comparison page will tell you. There is also a fourth path most of these comparisons skip entirely: staying inside the SAP ecosystem with a managed AMS partner instead of going fully independent.
What "Third-Party SAP Support" Actually Means (and What You Give Up)
Third-party SAP support means moving your maintenance and support contract off SAP entirely and onto an independent provider that has no relationship with SAP. Gartner classifies this as independent third-party software support, or TPSS, for the megavendor market (IBM, Microsoft, Oracle, SAP, and VMware by Broadcom) [VERIFY: CLAIM-ID].
The pitch is straightforward: significant cost savings, no forced upgrades, and support terms you negotiate rather than terms SAP sets for you. Gartner has reported TPSS savings of up to 50 percent annually against standard megavendor maintenance pricing [VERIFY: CLAIM-ID].
That savings figure is real for the right organization. It also comes with a trade-off that gets less airtime in vendor marketing:
- No SAP security notes: Independent providers have no access to SAP's intellectual property, patches, or security advisories. They write their own fixes.
- No roadmap access: You lose visibility into SAP's future release plans and cannot participate in early adoption programs.
- No RISE with SAP or cloud eligibility: Moving off SAP support generally forecloses SAP's cloud migration and subscription programs while the third-party contract is active.
- A difficult path back. Re-entering SAP support after leaving is a negotiated, often costly process, not a formality.
None of this makes third-party support the wrong call. It makes it a decision with a longer shadow than "we saved 40 percent on our maintenance bill this year." Keep that trade-off in mind as you read the comparison below, because it applies to all three providers equally.
Rimini Street: The Market Leader on Scale
Rimini Street is the largest and oldest name in this category, founded in 2005 as the company that effectively created independent third-party support for enterprise software.
Where it wins
Rimini Street supports the broadest range of enterprise software - SAP, Oracle, Salesforce, and others - through a global, follow-the-sun delivery model. For organizations with large, geographically distributed SAP estates, that scale is the differentiator: more engineers, more coverage windows, and more precedent handling complex, customized landscapes than either of the other two providers can match.
If your evaluation criteria are pure breadth and global reach, Rimini Street is the default shortlist entry.
Where to be careful
Rimini Street has a public litigation history with both SAP and Oracle stemming from disputes over intellectual property and support practices. The legal landscape around third-party support has shifted more than once over the past decade, and the current status of any specific matter should be verified directly - through Rimini Street's own investor disclosures or current legal reporting - before it factors into a procurement decision. What matters for a CIO is not the history itself but confirming the present-day facts before you sign.
Spinnaker Support: The Boutique, High-Touch Alternative
Spinnaker Support has operated in this space since 2008 and has built its position on service depth rather than sheer size.
Where it wins
Spinnaker supports Oracle, SAP, Salesforce, and VMware, combining support with managed services and consulting. Its model leans on flexible contract terms, including the ability to change scope as your landscape changes, and a public service guarantee: if Spinnaker fails to resolve an issue or defend a license compliance position, it commits to covering the cost of returning to the original software publisher.
For organizations that want a partner that adapts closely to their needs rather than a purely transactional support desk, Spinnaker is frequently cited as the strongest alternative to Rimini Street, without the legal complexity attached.
Trade-off
Spinnaker has fewer total clients and engineers than Rimini Street. For very large, multi-region enterprises with highly complex, heavily customized SAP landscapes, that smaller scale can matter more than the service-quality advantage does. It is a better fit for mid-sized and upper-mid-market estates than for the largest global deployments.
Support Revolution: The Budget and Regional Fit
Support Revolution is a UK-headquartered provider, founded in 2012, focused specifically on Oracle and SAP support.
Where it wins
Support Revolution differentiates on guaranteed response and resolution times written into the contract, not just promised in marketing copy. Its cost-effective staffing model, which includes support engineers based in India alongside its UK operations, allows it to offer materially lower pricing than the two larger providers while still covering core Oracle and SAP systems. For organizations in the UK or EMEA with smaller, less complex estates and a tight support budget, that combination of guaranteed SLAs and lower cost is the pitch.
Trade-off
Support Revolution operates at a meaningfully smaller scale than Rimini Street or Spinnaker. Coverage for very large, highly customized, or globally distributed SAP environments is narrower, and the advisory and innovation-enhancement services layered on top of support at the two larger providers are less developed here. It is the right fit for a specific profile of buyer, not a general-purpose alternative to the market leaders.
Side-by-Side: How the Three Compare
Use this table as a starting filter, not a final answer. The right column for your organization depends on estate size, risk tolerance, and how much of the "what you give up" section above your board is prepared to sign off on.
The Option These Comparisons Leave Out: Staying in the SAP Ecosystem
None of the three providers above will tell you this, because it is not their business model: you do not have to choose between paying SAP's full support fees and leaving the SAP ecosystem entirely. A managed Application Management Services (AMS) engagement through an SAP Gold Partner is a fourth path.
The distinction matters. AMS through a Gold Partner is not independent third-party support - it operates inside SAP's sanctioned partner ecosystem, which means you keep access to SAP security notes, patches, and the roadmap toward S/4HANA and RISE with SAP, while still gaining a dedicated, cost-managed support layer instead of paying full vendor rates for every ticket.
ITChamps runs this model as an SAP Gold Partner. Clients using ITChamps' AMS engagement have seen support costs reduced by as much as 40 percent without leaving SAP's official support structure - relevant context if your organization is also weighing the SAP ECC mainstream maintenance deadline of December 31, 2027, since AMS keeps your migration options (including S/4HANA) open in a way that independent third-party support does not.
This path is not the right fit for every organization. If your estate is stable, well-documented, and you have no near-term plans to touch S/4HANA, RISE, or SAP's cloud programs, one of the three independent providers above may still be the better economic decision. If you expect to migrate, expand, or need continued access to SAP's security and compliance updates, an AMS model through a Gold Partner is worth putting on the same shortlist before you sign a third-party contract you cannot easily unwind.
How to Choose: A Decision Framework for CIOs
Work through these questions in order. Each one should narrow the field before you request pricing from anyone.
- How large and complex is your estate? Large, global, heavily customized landscapes point toward Rimini Street's scale. Mid-market, moderately complex environments point toward Spinnaker. Smaller, simpler estates concentrated in the UK or EMEA point toward the Support Revolution.
- Do you have a migration on the roadmap in the next 24-36 months? If S/4HANA, RISE, or any SAP cloud program is plausible in that window, independent third-party support forecloses those paths while the contract is active. That is a reason to evaluate a Gold Partner AMS engagement before committing.
- What is your organization's risk tolerance for vendor legal history? If board-level scrutiny of vendor litigation is a real constraint, weigh that explicitly against Rimini Street's history and Spinnaker's comparatively cleaner record.
- What does "support" actually cost you today, and where? Break your current SAP maintenance spend down by ticket volume, severity, and module before comparing quotes. A 50 percent headline savings figure means less if your actual support usage is already low.
- Who owns the decision to walk away from SAP's roadmap? This should be a named executive sign-off, not a procurement line item. The reversibility of this decision is lower than most software purchasing decisions your organization makes.
If the answers point toward permanently exiting SAP's ecosystem, the three providers above are a reasonable shortlist, weighted by the criteria in the table. If the answers point toward keeping SAP-sanctioned access while still controlling cost, a Gold Partner AMS conversation belongs on the table first.

Frequently Asked Questions
Is Rimini Street or Spinnaker Support better for SAP?
It depends on estate size and risk tolerance. Rimini Street offers greater scale and broader multi-vendor coverage, which suits large, complex, global SAP landscapes. Spinnaker Support is generally favored by organizations that prioritize high-touch service and contract flexibility and want to avoid Rimini Street's litigation history, particularly in the mid-market.
Does Support Revolution support SAP as well as Oracle?
Yes. Support Revolution provides independent support for both Oracle and SAP systems, though its core positioning and largest customer base have historically centered on Oracle, with SAP support offered as part of a broader independent maintenance model.
What do you lose by moving to third-party SAP support?
You lose access to SAP's official security notes and patches, visibility into SAP's product roadmap, and eligibility for RISE with SAP and other SAP cloud migration programs for as long as the third-party contract is active. Re-entering SAP's official support after leaving requires a separate negotiated process.
Is there an alternative to third-party support that still reduces SAP costs?
Yes. A managed AMS engagement through an SAP Gold Partner reduces support costs while keeping your organization inside SAP's sanctioned support and roadmap structure, unlike fully independent third-party providers. This preserves eligibility for S/4HANA migration and RISE with SAP.
How much can organizations save by leaving SAP's direct support?
Gartner has reported that independent third-party software support can deliver savings of up to 50 percent annually compared to standard megavendor maintenance pricing, though actual savings vary based on contract terms, estate complexity, and current support usage.
