SAP Commerce EoMM: What It Means and What You Need to Do Now

If you run SAP Commerce on-premises, you’ve got a deadline: July 31, 2026. That’s when SAP ends Mainstream Maintenance for SAP Commerce (formerly Hybris) on-prem (SAP Help Portal, 2026). After that, your platform enters a very different support reality.

This isn’t some distant problem anymore. Over 3,200 companies currently run SAP Commerce Cloud or on-prem deployments (6sense, 2025). Many still haven’t started planning. And the companies that act early will spend less, disrupt less, and land in a stronger position than those who wait.

TL;DR: SAP Commerce on-prem reaches End of Mainstream Maintenance on July 31, 2026 (SAP Help Portal, 2026). After that: no new features, optional security patches, deprioritised support. Three paths forward: migrate to SAP Commerce Cloud (3–6 months), go composable (6–12 months), or pay for extended support. We migrated Franke in 90 days. The window for comfortable timelines is closing.

What Does EoMM Actually Mean?

SAP has been a Leader in the Gartner Magic Quadrant for Digital Commerce for 11 consecutive years (SAP News Center, 2025). But that leadership is focused on Commerce Cloud, not on-prem.

End of Mainstream Maintenance doesn’t mean SAP switches off your servers. Your storefront keeps running. But here’s what changes in practice.

No more feature packs. SAP stops delivering new functionality for the on-prem version. Every competitor that upgrades pulls ahead of you.

Security patches become optional for SAP. Critical vulnerabilities may still get patches, but non-critical ones won’t. Your attack surface grows with every passing month.

Support cases get deprioritised. SAP focuses engineering resources on Commerce Cloud. On-prem tickets go to the back of the queue.

Custom support is expensive. Extended maintenance (Customer-Specific Maintenance) is available but comes at a premium, typically 2 to 4% on top of your existing fees, and still doesn’t include new features.

In practice, EoMM means your platform starts falling behind on day one. The gap between where you are and where the market expects you to be widens every quarter.

What Are the Three Paths Forward?

The global B2B e-commerce market is worth $32.1 trillion and growing at 14.5% CAGR (Statista, 2025). Standing still isn’t an option. Every SAP Commerce on-prem customer faces the same three paths.

Path 1: Migrate to SAP Commerce Cloud

This is the most common choice, and for good reason. SAP Commerce Cloud is the direct successor. Your existing data models, business logic, and integrations carry over. The platform runs on SAP’s managed infrastructure with automatic updates, built-in CDN, and elastic scaling.

Best for companies that have invested heavily in SAP Commerce customisations and want to preserve that investment while gaining cloud benefits.

Timeline: 3 to 6 months for a typical migration. We completed the Franke migration in 90 days.

Path 2: Go composable

Some companies use EoMM as the trigger to rethink their entire commerce architecture. A composable approach replaces the monolithic SAP Commerce platform with best-of-breed services: a headless CMS, a separate PIM, an independent order management system, and a modern frontend framework.

Best for companies with strong internal development teams, complex multi-brand requirements, or a clear need for frontend flexibility that Commerce Cloud doesn’t provide.

Timeline: 6 to 12 months depending on scope. Requires more upfront architecture work. But if your situation genuinely calls for it, this is the right time to make the jump.

Path 3: Extend support and decide later

SAP offers Customer-Specific Maintenance beyond July 2026. You keep running on-prem, pay more for diminishing support, and push the migration decision into the future.

Best for companies that genuinely can’t migrate by July 2026 due to regulatory freezes, M&A activity, or resource constraints. Fair enough, sometimes you have no choice.

Risk: this path gets more expensive every year. The talent pool for on-prem SAP Commerce is shrinking. The cost of eventually migrating only goes up.

Why Is Waiting the Riskiest Option?

83% of data migration projects either fail or exceed their budgets and schedules (Bloor Group, 2023). Starting late only makes those odds worse.

Costs compound. Extended maintenance fees start immediately after EoMM. Meanwhile, your internal teams spend more time patching, monitoring, and working around limitations that a cloud platform handles automatically. Developers already lose 23% of their working time dealing with technical debt (Journal of Systems and Software, 2023). After EoMM, that percentage only grows.

Talent disappears. SAP Commerce on-prem developers aren’t growing in number. The experienced ones are moving to cloud projects. Finding and retaining on-prem specialists gets harder and more expensive every quarter. I’ve seen this play out firsthand with clients who couldn’t fill a critical on-prem role for 4 months.

Security exposure grows. Without regular patches, your platform becomes a liability. A single breach costs more than a full migration.

Business agility suffers. Your marketing team wants a new checkout flow. Your product team needs better personalisation. On a frozen platform, every change is a custom development project. On Commerce Cloud, many of these capabilities come out of the box.

How Should You Make This Decision?

Here’s a practical framework.

1. Audit your customisations. How many are still business-critical? In our experience, 25 to 35% of on-prem customisations are unnecessary on Commerce Cloud because the platform handles them natively.
2. Map your integrations. What connects to your commerce platform? ERP, PIM, CRM, payment providers, logistics? Map every dependency. This is where surprises hide.
3. Calculate your real TCO. Include not just licence fees but infrastructure costs, internal staffing, opportunity cost of delayed features, and security risk. The full picture is usually sobering.
4. Set a target date. Work backwards from July 2026. If you need 4 months to migrate, your project kickoff is March 2026 at the latest. And that’s cutting it tight.
5. Talk to someone who’s done it. We migrated Franke from SAP Hybris to Commerce Cloud in 90 days and won an SAP Quality Award for the project.

Is 90 Days Really Enough?

90% of businesses that migrated e-commerce platforms reported sales and revenue improvements (commercetools, 2024). The Franke project proved that a focused, well-planned migration can happen in three months. Not years. Not even six months. Ninety days from kickoff to go-live.

The difference between companies that migrate smoothly and those that scramble? Timing. The ones who start now choose their pace. The ones who wait have the pace chosen for them.

Frequently Asked Questions

When exactly does SAP Commerce EoMM take effect?

SAP Commerce on-premises reaches End of Mainstream Maintenance on July 31, 2026 (SAP Help Portal, 2026). After this date, SAP stops delivering feature packs, deprioritises support cases, and makes security patches optional. Extended support (Customer-Specific Maintenance) is available at additional cost but doesn’t include new features.

What happens if we don’t migrate by the deadline?

Your platform keeps running. SAP doesn’t switch it off. But you lose access to new features, get deprioritised support, face growing security risk from unpatched vulnerabilities, and pay premium rates for extended maintenance. Every quarter after EoMM, the gap between your platform and the market widens.

How much does extended maintenance cost after EoMM?

SAP’s Customer-Specific Maintenance typically adds 2 to 4% on top of your existing maintenance fees. But the real cost is broader: your internal teams spend more time on workarounds, finding on-prem specialists gets harder, and the eventual migration becomes more expensive as talent and partner capacity shifts to cloud projects.

Can we migrate from SAP Commerce on-prem to a non-SAP platform?

Yes. EoMM is a trigger point where some companies choose to go composable or switch to platforms like Shopify, commercetools, or Adobe Commerce. This path takes longer (6 to 12 months) and requires more upfront architecture work, but it’s viable for companies that want to rethink their entire commerce stack.

What’s the fastest SAP Commerce migration you’ve completed?

We migrated Franke from SAP Hybris to SAP Commerce Cloud in 90 days. That project won an SAP Quality Award. The key factors were a disciplined preparation phase, structured customisation audit (which eliminated 30%+ of unnecessary code), and iterative delivery. Speed is achievable when the approach is spot on.
