Why SAP S/4HANA Migration Timelines in KSA Are Slipping, and What to Do About It

For enterprise leaders in Saudi Arabia, the date December 31, 2027, has transitioned from a theoretical milestone into a looming operational reality. This is the hard deadline for the end of SAP ECC mainstream support. While it may seem like there is time on the calendar, the complexity of a typical migration means that the window for a controlled, strategic transition is narrowing rapidly.

Across the Kingdom, there is a visible gap between where most enterprises are and where they need to be. Many organizations that intended to be mid-project by 2026 are still caught in the gravity of early discovery or planning. As we move closer to the deadline, the market is bracing for a significant resource squeeze. Industry analysts suggest that consulting and implementation costs could rise by as much as 30-50% as the deadline approaches and the rush to migrate begins in earnest.

If your migration timeline is starting to slip, you are not alone. Understanding why this is happening across the KSA market, and how a few leading organizations are managing to stay ahead, is critical to protecting your transformation roadmap.

Why Timelines Are Slipping: The Four Drivers in KSA

In my work supporting SAP programs across the region, I see four consistent factors that derail migration schedules. These aren’t just technical glitches; they are structural challenges unique to the Saudi market environment.

1. Legacy Landscape Complexity

Many Saudi conglomerates, as well as manufacturing companies, have been operating with SAP for about fifteen to twenty years. During this period, their systems have undergone numerous customizations to specifically cater to the unique requirements of the business. These Z-programs as well as tailor-made enhancements, although they have been instrumental in the past, are currently acting as a heavy burden. Going through two decades of custom code and modifying it to the ‘Clean Core’ approach of S/4HANA is an extremely huge task which almost always consumes more time than was originally planned.

2. The Talent Shortage

The demand for S/4HANA expertise in the Kingdom has completely outstripped the available supply. Every major enterprise is looking for the same pool of architects and functional consultants simultaneously. When a key lead leaves a project or a role remains unfilled for months, the entire project timeline shifts. We are seeing a talent war where the Big 4 consultancies and internal IT departments are competing for a very limited group of practitioners who have actually delivered a full-cycle S/4HANA implementation.

3. The ZATCA Compliance Overlap

Saudi Arabia’s regulatory environment is moving just as fast as its digital one. The requirement for ZATCA e-invoicing (Phase 2) integration has added a mandatory layer of work to ERP teams. Many organizations made the mistake of treating ZATCA compliance and S/4HANA migration as separate projects. This leads to conflicting priorities for the same technical resources, causing both workstreams to slow down.

4. Deployment Decision Paralysis

The choice between RISE with SAP (Private Cloud), Public Cloud, or continuing with On-Premise is not just a simple technical choice. It includes complicated discussions about data residency, sovereignty, and long-term TCO. In KSA, these discussions normally involve several stakeholders from departments such as IT, Finance, and Legal. When these kinds of decisions are postponed and only brought up during the project’s execution phase, it results in a wait-and-see attitude which can lead to the demise of the project momentum.

The Talent Bottleneck: Roles That Stall Projects

When we look at where the missing links are in the Saudi SAP market, it isn’t the generalists who are missing. It is the highly specialized leads who understand the modern SAP ecosystem.

The hardest roles to fill in 2026 include:

• S/4HANA Solution Architects: The visionaries who can map complex business processes to the new digital core.
• RISE Implementation Leads: Specialists who understand the nuances of the “RISE with SAP” offering and cloud transformation.
• SAP BTP Specialists: As organizations aim for a Clean Core, the Business Technology Platform becomes the essential hub for extensions and integrations.
• SAP Program Managers: Leaders who have the regional experience to navigate KSA-specific challenges while keeping global consultancies on track.

Through generalist channels, we see an average time-to-fill for these roles of 8 to 12 weeks. For a project on a tight schedule, an empty seat for three months is catastrophic. Working with a specialist partner can often compress this hiring cycle to just one or two weeks, providing professionals who are already in-region and ready to contribute.

What Successful Programmes Do Differently

Despite these challenges, some organizations in the Kingdom are hitting their milestones. They aren’t doing it by spending more; they are doing it by working differently.

Early Talent Planning: Successful leaders don’t wait for a project phase to start before looking for people. They treat talent planning as a 6-12 month lead activity. They identify the critical path roles early and secure them before the market peaks.

Specialist Technology Partnerships: Instead of relying solely on the Big 4, who are often stretched thin, leading firms are partnering with specialist technology solutions providers. These partners provide the boots on the ground specialists who can fill technical gaps immediately, often deployed on IQAMA within days. This allows the internal team to focus on business logic while the specialists handle the technical migration.

Coordinated Workstreams: Rather than seeing ZATCA as a distraction, top-tier programs integrate ZATCA requirements directly into the S/4HANA migration path. By aligning the data structures and integration points once, they save hundreds of man-hours in testing and deployment.

Early Deployment Finality: The projects that have been most effective are those where the debate Cloud vs. On-Premise is resolved within the first 30 days of discovery. They engage data sovereignty experts very early so that the selected architecture complies with all the KSA national requirements, thereby circumventing a mid-project pivot, which could cause months to be added to the timeline.

Conclusion 

Opportunities for well-managed, stress-free migrations to S/4HANA are becoming fewer. With only the last 20 months till the ECC support deadline, the companies that will be able to make it are those who effectively take control of their talent strategy and planning today.

If your organization decides to wait until 2027 to address the resourcing challenge, it will face higher costs and lower quality. On the other hand, by resolving the talent bottleneck now and making decisive moves regarding deployment and compliance integration, your organization can transform the SAP migration from a risky exposure to a growth platform.
