For many CFOs, deciding when and how to implement SAP S/4HANA could be the most significant technology investment choices of their career. It’s a big deal. SAP HANA® is SAP's brand of in-memory computing, a technology that handles massive data sets without breaking a sweat. SAP® built its latest next-generation intelligent ERP (SAP S/4HANA) around this technology. SAP launched SAP S/4HANA in 2015 and plans to stop supporting older ERP versions on December 31, 2027. SAP reports more than 12,000 customers have committed to SAP S/4HANA.¹
Traditional ERP systems are optimized for transaction processing, with data stored in many different tables. SAP S/4HANA uses its Universal Journal to store all financial transaction details in one table. Availability and access to all that data can happen with near-zero latency. The new system also brings a simplified data model that lets you record once, use many times, and create a single source of truth. So analytics and insights that were historically unfeasible or very time consuming now process quickly.
SAP S/4HANA enables more speed and better insights in almost every area of finance. It’s also a platform for real-time analytics—with no more waiting for separate reporting systems, batch jobs, and long processing times. Yes, it can be expensive, and yes, there may be implementation risks, but defining a digital transformation roadmap upfront, driven by prioritized capabilities that drive value for the business, can help address both cost and risk in a positive way.
Will every company using SAP today step up to SAP S/4HANA? Probably not every company, but this is a watershed moment for SAP customers. Among organizations sticking with SAP, four factors seem to be shaping their decisions:
SAPinsider says that a little more than half of SAP customers planning SAP S/4HANA investments are opting for either new implementation or system conversion.2
Those choosing a new implementation typically want to eliminate custom programs, shed ineffective practices, and drive more standardization around best practices. Organizations that implemented SAP when they had simpler business models, different competitors, and a less demanding customer base find this approach allows for remodeling to support productivity and growth. It also lets them start afresh and keep their ERP clean.
Those choosing system conversion usually want to preserve some of their custom environments and have business models that have not evolved. They see this as a lower-cost path, one that could require less change management. This approach is often used by companies that completed SAP implementation within the last five to seven years. These companies don’t need to transform, but they want to take advantage of the SAP S/4HANA digital platform.
For many SAP customers, a new implementation or system conversion can be combined with a third implementation option: leveraging SAP Central Finance.
SAP Central Finance allows companies to deploy a single instance of SAP S/4HANA Finance and then integrate some or all their financial and operational processes back through that instance. A company’s current SAP or non-SAP financial systems don’t need to be converted and can remain in their existing environments.
Deloitte has more than 110 SAP S/4HANA implementations currently underway, with a significant portion of clients leveraging Central Finance as a low-risk, high-value path forward. With more than 30,000 hours of co-innovation partnering with SAP on SAP S/4HANA, here’s what we know from our experience:
Companies committed to SAP will likely find themselves grappling with SAP S/4HANA decisions over the next five years. Making choices earlier—building in time for your teams to influence both the overall vision and the implementation options—should increase the odds of getting things right.
