Cutting SAP ECC Maintenance Costs
Before 2027

What You Are Actually Paying For

Annual maintenance for SAP ECC is calculated as a percentage of the net licence value. Enterprise Support runs at approximately 22%. Standard Support runs at approximately 17%. This percentage is applied to the original discounted licence value, not list price, meaning that the actual maintenance rate as a percentage of what you paid depends heavily on the discounts negotiated at the time of purchase. For customers who secured deep discounts of 60-70% off list, the maintenance-to-paid-licence ratio can exceed 100% within five years. That means you have paid more in cumulative maintenance than you ever paid for the licences themselves.

SAP Enterprise Support, the tier most large organisations are on, provides access to SAP's support portal (SAP ONE Support Launchpad), software updates and patches including Enhancement Packages, legal and regulatory updates, and 24/7 access to SAP's technical support team for Priority 1 issues. It also includes access to SAP Solution Manager and certain remote support tools. In theory, this is a comprehensive package. In practice, many organisations use only a fraction of these services, particularly if their ECC systems are stable and not undergoing active development.

The escalation problem is where maintenance costs become truly punitive. SAP has historically applied annual increases of 3-4% to maintenance fees. In 2024, this jumped to approximately 5%, with some customers reporting increases as high as 8% when factoring in inflation adjustments and contractual price escalation clauses. These increases are typically applied automatically at renewal and, unless actively challenged, compound year after year. Over a five-year period, an unchallenged 5% annual increase turns a $4 million annual bill into $5.1 million. That is $1.1 million in additional spend for the same service level.

Shelfware is the invisible cost multiplier in most SAP estates. Shelfware, licences that are purchased but not actively deployed or used, is endemic. It arises from over-purchasing during initial rollouts, from business units that decommissioned SAP-dependent processes, from merger-related licence accumulation, and from SAP's bundling practices that require purchasing broader module sets than needed. The maintenance cost of shelfware is particularly insidious because it is invisible to most budget holders: the fees are buried in a single annual renewal invoice with no line-item visibility into which licences are generating the charges. Across our client engagements, shelfware typically accounts for 15-30% of the total SAP maintenance bill.

The 2027 Support Deadline: Threat or Opportunity

SAP's mainstream support for ECC 6.0 is scheduled to end on 31 December 2027. After that date, SAP will no longer provide standard support for ECC under existing maintenance agreements. Instead, SAP offers extended maintenance through 2030 at an additional premium, typically a 2% uplift on top of existing maintenance fees, with no functional enhancements, no new Enhancement Packages, and a progressively diminishing support investment from SAP's side.

Most organisations view the 2027 deadline as a threat. It is also significant negotiation leverage. SAP's revenue model depends on retaining its installed base. Every customer that exits SAP maintenance, whether to third-party support, a competitor ERP, or simple cost optimisation, represents a permanent revenue loss. Between now and 2027, SAP's account teams are under intense pressure to secure long-term commitments, whether through RISE with SAP conversions, S/4HANA licence sales, or extended support agreements. This pressure means SAP is more flexible on pricing, terms, and concessions than at almost any other time in the past decade.

Path A: Migrate to S/4HANA. Full conversion by 2027. Requires significant investment, typically 1.5-3x annual SAP spend. SAP offers migration credits and conversion discounts, but these must be negotiated aggressively.

Path B: Extended Maintenance. Stay on ECC through 2030. Buys time but at escalating cost (22% plus 2% premium plus annual increases). No new functionality. Increasingly limited support responsiveness.

Path C: Third-Party Support plus Optimisation. Transition to independent support. 50%+ cost reduction. Indefinite support timeline. Preserves migration flexibility. Requires careful planning but delivers immediate savings.

The critical insight is that these paths are not mutually exclusive. The most effective strategy often combines elements: negotiate an improved SAP maintenance deal in the short term, eliminate shelfware immediately, transition non-critical or frozen modules to third-party support, and preserve the option to migrate selected workloads to S/4HANA on your own timeline, not SAP's.

Optimising Your SAP Support Renewal

Before the next SAP maintenance renewal, a structured review of the contract and usage can unlock substantial savings, even without moving to third-party support. These tactics are applicable regardless of the long-term ERP strategy.

Eliminate shelfware licences. Identify every SAP module, user type, and engine licence that is not actively deployed in production. Common culprits include unused SAP BusinessObjects licences, over-provisioned Professional user types when Limited Professional or Employee Self-Service would suffice, and modules purchased as part of bundle deals but never implemented. For every licence removed from maintenance, you recover 22% of its value annually, a permanent reduction. SAP's willingness to accept partial terminations varies, but approaching this with detailed usage data and a firm position typically yields results.

Downgrade your support tier. If the organisation does not require SAP's full Enterprise Support, evaluate lower-cost alternatives. Product Support for Large Enterprises (PSLE) offers reduced fees for customers who do not need the full Enterprise Support scope. If SAP systems are stable and the organisation rarely engages SAP support for incidents, a lower tier may be appropriate. The difference between Enterprise Support at 22% and Standard Support at approximately 17% on a $20 million licence base is $1 million annually, a material saving for a reduced service level that many organisations would never notice.

Lock in multi-year pricing. Use the 2027 deadline as leverage to negotiate a multi-year maintenance agreement with fixed pricing. SAP may be willing to cap annual increases at 0-3% rather than 5-8% in exchange for a commitment through 2027 or beyond. This provides budget certainty and eliminates the compounding effect of unchecked annual escalations. A 3-year deal at 0% increase versus a 5% annual increase saves approximately 15% in cumulative maintenance costs over the term.

Leverage future S/4HANA plans. If evaluating or planning an S/4HANA migration, use that intent as negotiation currency. SAP's account teams are heavily incentivised to secure S/4HANA commitments, and they will often offer short-term maintenance discounts, migration credits, or deferred payments to customers who signal genuine migration interest. The key is to make SAP work for your commitment rather than giving it away. Extract concrete concessions before signing anything.

Challenge annual price increases. Many SAP customers accept annual price escalations as non-negotiable. They are not. SAP's standard contract language typically permits increases, but the actual percentage is often discretionary. Push back every year, formally, in writing, before the renewal date. Customers who consistently challenge increases pay measurably less than those who accept them passively. Over a five-year period, the difference between a 2% and an 8% annual increase on a $4 million base is $1.3 million.

Third-Party Support: A Strategic Alternative

Third-party SAP support, delivered by independent providers outside of SAP, has matured significantly over the past decade and now represents a credible, proven alternative for organisations seeking to dramatically reduce ECC maintenance costs. Leading providers such as Rimini Street and Spinnaker Support typically charge approximately 50% of SAP's maintenance fee, delivering immediate annual savings while offering service levels that often exceed SAP's own support in responsiveness and scope.

Extended system life with no artificial end date. Unlike SAP's 2027 deadline, third-party support providers commit to supporting the current ECC system for 15+ years from the date of engagement. There is no forced migration timeline, no end-of-support cliff, and no escalating "extended maintenance" premium. You decide when to move, based on business readiness, not vendor pressure. This is particularly valuable for organisations whose S/4HANA migration timeline extends beyond 2030, or who have decided to explore non-SAP alternatives for selected workloads.

Custom code and interface support is included as standard. SAP's standard support explicitly excludes assistance with custom ABAP code, bespoke interfaces, and third-party integrations, even though these are often the most common sources of production issues. Third-party providers typically include custom code support covering ABAP programmes, user exits, enhancements, and custom reports. For heavily customised ECC environments, this alone can justify the transition: broader support scope at half the cost.

Tax, legal, and regulatory updates are delivered independently. A common concern about leaving SAP support is loss of access to tax and regulatory updates such as country-specific payroll or VAT changes. Reputable third-party providers address this through their own in-house development teams, which produce and deliver these updates for all supported SAP versions. The updates are delivered as ready-to-apply packages, often with implementation guidance tailored to the customer's specific configuration.

No forced upgrades or version pressure. Third-party support allows the organisation to remain on its current ECC version indefinitely. There are no mandatory Enhancement Packages, no SAP-imposed upgrade cycles, and no artificial pressure to move to S/4HANA. This "run what you have" approach is well-suited to organisations with stable, mature ECC deployments that deliver full business value without requiring new SAP functionality.

How SAP Enterprise Support compares to third-party support across key dimensions. Annual fees under SAP run at approximately 22% of licence value and rise annually; third-party fees typically run at approximately 50% of SAP's fee and are usually fixed. SAP's support timeline runs to 2027 mainstream and 2030 extended with a 2% premium; third-party is indefinite at 15+ years with no end date. SAP delivers full patches, Enhancement Packages, and security fixes; third-party delivers critical bug fixes, tax and regulatory updates, and security advisories. Custom code is not covered under SAP standard support; it is fully covered by third-party providers including ABAP, interfaces, and bespoke reports. SAP offers migration credits and upgrade incentives; third-party offers no migration credits but cumulative savings fund future transitions. SAP's annual escalation runs 3-8% and is recently trending higher; third-party is typically 0% or capped at 2-3%.

Cost Modelling: Quantifying the Savings Opportunity

Understanding the financial impact requires modelling multiple scenarios against your actual SAP maintenance baseline. The following illustrative model uses a mid-to-large enterprise with $5 million in annual SAP ECC maintenance, comparing four strategic paths over a five-year period from 2025 to 2030.

Scenario A: Status quo with 5% annual increase. Year 1 at $5.00 million, Year 3 at $5.51 million, Year 5 at $6.08 million, five-year total of $27.6 million. This is the baseline: passive renewal with no intervention.

Scenario B: Negotiate fixed pricing at 0% increase. Year 1 through Year 5 at $5.00 million each, five-year total of $25.0 million. Saves $2.6 million (9%) versus baseline. This is the minimum any organisation should achieve simply by challenging annual escalation.

Scenario C: Shelfware removal plus fixed pricing. Year 1 through Year 5 at $3.75 million each, five-year total of $18.8 million. Saves $8.8 million (32%) versus baseline. This stays on SAP support but eliminates shelfware and locks pricing, delivering substantial savings with minimal operational change.

Scenario D: Third-party support plus shelfware removal. Year 1 through Year 5 at $1.88 million each, five-year total of $9.4 million. Saves $18.2 million (66%) versus baseline. This is the full optimisation path combining shelfware elimination with a 50% third-party support discount on the remaining base.

The difference between Scenario A (passive renewal) and Scenario D (full optimisation) is $18.2 million over five years, capital that can be redirected to S/4HANA migration, cloud modernisation, or other strategic IT investments. Even the moderate Scenario C delivers $8.8 million in savings with minimal operational change. Scenario D assumes a 25% shelfware reduction (reducing the base from $5 million to $3.75 million) followed by a 50% third-party support discount on the remaining base. In practice, results vary, but across our engagements, these assumptions are conservative. Some organisations achieve even larger shelfware reductions, and third-party providers occasionally offer deeper introductory discounts.

Key Risks and How to Mitigate Them

Leaving SAP's official support is a consequential decision with implications that extend beyond cost. A well-prepared CIO addresses each risk explicitly before executing any changes.

Loss of access to SAP patches and Enhancement Packages. Once you leave SAP Enterprise Support, you no longer receive SAP-delivered patches, security notes, or Enhancement Packages. For organisations running stable ECC deployments with no plans to implement new SAP functionality, this is often acceptable because the system is frozen by design. Third-party providers deliver critical bug fixes and security advisories through their own engineering teams. However, if the ECC system is still undergoing active development or requires new SAP features, remaining on SAP support for those modules is advisable.

Future S/4HANA migration implications. SAP offers migration credits and conversion discounts to customers who remain on SAP Enterprise Support. Customers who leave SAP support may lose access to these incentives. However, the financial analysis often reveals that the cumulative savings from third-party support more than offset the lost migration credits. If the S/4HANA migration is 3+ years away, the savings generated in the interim can directly fund the migration, often with money to spare. Our guide on RISE with SAP versus traditional on-premise SAP licensing explores this trade-off in detail.

SAP audit exposure. SAP retains the right to audit licence compliance regardless of whether you are on SAP support. Some organisations report increased audit activity following support termination. The mitigation is straightforward: ensure licence compliance is watertight before making any changes. Conduct an internal licence reconciliation (or engage an independent firm) to verify that deployed user counts, digital access usage, and engine metrics align with contractual entitlements. A clean compliance position eliminates SAP's most potent leverage.

Reinstatement costs if you return to SAP support. If you leave SAP support and later wish to return, SAP charges a reinstatement fee, typically the full back-maintenance for all years during which support was not paid, plus a penalty premium. This can be substantial. However, reinstatement is relatively rare: most organisations that transition to third-party support find the service level acceptable and have no reason to return. The financial model should include a reinstatement scenario for risk quantification, but it should not be the primary basis for decision-making.

Provider selection risk. Not all third-party support providers are equal. The market is dominated by Rimini Street, the largest and publicly traded with the broadest coverage, and Spinnaker Support, with several smaller regional players. Evaluate providers based on their track record with SAP ECC specifically, their ability to deliver country-specific tax and regulatory updates for your operating jurisdictions, their SLA terms and response times, and their financial stability. Request customer references from organisations of comparable size and SAP footprint complexity.

Enterprise Case Examples

Global manufacturer: $8 million saved through licence optimisation and third-party maintenance. A US-based manufacturing company with a $6.5 million annual SAP maintenance bill across ECC 6.0, BW, and BusinessObjects. The S/4HANA migration timeline was 2029+, making three more years of SAP Enterprise Support commercially unjustifiable. Redress Compliance conducted a full licence usage audit, identified 22% shelfware (primarily unused BusinessObjects and over-provisioned Professional User licences), and managed the transition of stable ECC modules to third-party support while retaining SAP Enterprise Support for BW which was still under active development. Annual SAP maintenance was reduced from $6.5 million to $3.2 million, saving $8 million over the first 3 years with zero operational disruption. The hybrid approach, third-party for stable modules and SAP for active development, delivered the best balance of cost savings and risk management. Read the full case study.

European retail chain: avoids 10 million euro penalty and cuts renewal costs by 20%. A large European retail chain faced both a SAP audit claim and an upcoming ECC maintenance renewal. SAP's audit findings alleged significant under-licensing of digital access (indirect use), creating a potential penalty of 10 million euros+ that was being linked to the renewal conversation. Redress Compliance separated the audit defence from the renewal negotiation, challenged SAP's digital access calculation methodology, and negotiated a RISE with SAP renewal package that addressed both the compliance position and the ongoing maintenance costs. The audit penalty was eliminated through technical rebuttal, and renewal costs were reduced by 20% through restructured agreement terms. SAP often links audit findings to renewal pressure. Separating the two conversations and challenging audit methodology independently is essential for fair outcomes. Read the full case study.

US financial services firm: $5 million savings with flexible RISE deal. A mid-market US financial services company running ECC with a $4.2 million annual SAP bill. The firm was evaluating RISE with SAP but was concerned about cloud lock-in and pricing transparency. Redress benchmarked SAP's RISE proposal against market norms, identified over-provisioned cloud capacity, and negotiated contractual flexibility including annual right-sizing, exit protections, and capped annual escalation. The result was $5 million in savings over the deal term, with contractual flexibility to scale down or exit without penalty. RISE with SAP can deliver value, but only when the commercial terms are negotiated independently with market benchmarking and contractual safeguards. Read the full case study.

Your 8-Step Action Plan

Step 1: Assemble a cross-functional task force. Form a team spanning IT, procurement, finance, and legal to drive SAP maintenance cost reduction. Assign clear ownership: one person accountable for licence data, one for vendor negotiation, one for third-party evaluation. This initiative touches contracts, budgets, and operational systems. It requires cross-functional alignment to succeed.

Step 2: Baseline your current SAP spend. Document every SAP licence, module, and associated maintenance charge. Calculate total ECC maintenance spend, identify the effective maintenance rate, and flag every licence with zero or minimal usage. This baseline is the foundation for every subsequent decision.

Step 3: Identify and quantify shelfware. Using LAW/USMM data and stakeholder interviews, identify every unused or under-utilised SAP licence. Quantify the annual maintenance cost attributable to each. Prioritise the largest cost items for immediate termination or renegotiation.

Step 4: Obtain third-party support proposals. Request scoping and pricing from at least two independent support providers. Compare their service scope, SLA terms, and pricing against SAP Enterprise Support. Even if you do not switch, having a credible third-party proposal strengthens your negotiation position with SAP immeasurably.

Step 5: Model multiple scenarios. Build 3-year and 5-year cost models covering: status quo, negotiated renewal, shelfware elimination, partial third-party transition, and full third-party transition. Include SAP's annual escalation assumptions, reinstatement costs, and migration credit trade-offs. Present the models to finance leadership to establish the business case.

Step 6: Negotiate with SAP from a position of strength. Approach SAP with data: your shelfware analysis, your third-party proposals, and your scenario models. Make clear that you are evaluating alternatives and that the renewal terms must reflect the value SAP delivers, not simply continue historical pricing. Our SAP negotiation guide provides detailed tactics for this conversation.

Step 7: Execute and document every change. Whether you negotiate a better SAP deal, terminate shelfware, or transition to third-party support, execute meticulously. Submit termination notices within contractual windows, obtain written confirmation of all concessions, and verify that invoices reflect agreed changes. A single missed notice period can cost the organisation a full year of unnecessary maintenance.

Step 8: Establish ongoing governance. Implement quarterly SAP licence and support reviews to prevent shelfware re-accumulation, track escalation rates, and maintain compliance readiness. Build a renewal calendar with 90-day advance alerts. SAP cost optimisation is not a one-time project. It is a permanent organisational capability.
