For many organizations, SAP is not just another IT system – it is the operational backbone. Financial data, supply chain flows, production planning, procurement, reporting – a large share of mission-critical processes runs on SAP. No one wants to create instability in such an environment. That mindset is understandable and professional. It is also why system integrators (SIs) and consulting firms enjoy such a high level of trust: They know the platform, the architecture, and often the organization itself very well. Their recommendations carry weight.
Yet this trust sometimes leads companies to make decisions that, on closer inspection, may not be in their best interest. One recurring example emerges whenever the question comes up whether automation initiatives – for example in accounts payable invoice management – must be postponed until “S/4HANA is done.”
Many SIs advise: no side projects, full focus on the migration. And there is a rational core to that recommendation. With ECC mainstream maintenance ending, time is limited. Resources are tight because many organizations are migrating in parallel. Maintaining focus matters.
But focusing on S/4HANA cannot mean freezing all other progress. And this is exactly where a closer look pays off – especially for SAP, finance, and AP leaders who not only run systems but are responsible for advancing their organization’s value creation.
System integrators are generalists with strong SAP expertise. They know how to run large transformation programs, how to plan brownfield and greenfield approaches, how to make architectural decisions, and how to orchestrate cloud models. This knowledge is essential – but it does not cover everything.
When it comes to specific business processes such as accounts payable, SI knowledge is typically broader than it is deep. The truly in-depth process expertise resides with specialized vendors and subject matter experts who spend their days answering questions like: What does “best in class” look like in AP? Where are the real automation opportunities in invoice management? And how do you create standardization in SAP without ignoring business requirements?
This is not a criticism of SIs. They have a clear and important role. But it does mean that for certain decisions, organizations should bring in additional experts who can provide the right answers to questions around SAP-integrated invoice processes.
Automating invoice management checks every box needed to rise to the top of the priority list during a transformation – not to be pushed to the bottom. And there are strong reasons for that:
First: It is a document-based, highly standardizable process.
A perfect foundation for automation.
Second: It is still heavily manual in many organizations.
Manual work means errors, delays, rework, and media discontinuities. Automation creates immediate, visible improvement.
Third: The document volume is high and recurring.
Few finance processes deliver ROI as quickly as accounts payable automation.
In short: AP invoice automation is one of the clearest and fastest value drivers available to finance leaders.
Many decision-makers worry that an AP automation initiative could become as large and complex as an S/4HANA migration. And at times, this is how it is communicated: too risky, too much effort, too much change. But that assumption does not reflect reality.
If organizations focus on three core criteria when selecting a provider, they avoid risk – and they certainly do not create a second major project:
- Deep specialization in SAP
A provider must understand how SAP works, how processes are integrated, and how to build stable software architectures.
- Extensive experience from invoice automation projects
Only hands-on experience leads to true best-practice implementation.
- A solution that already covers most requirements in standard
More standard means less effort. Less custom development means lower risk and greater long-term viability.
When these criteria are met, the project timeline is not measured in months. With specialized vendors like xSuite, implementations often take only days or a few weeks. This is an entirely different magnitude compared to the S/4HANA migration itself.
A frequent reason companies avoid AP automation before migrating to S/4HANA is the fear of double work. Many ask:
“If we implement a solution on SAP ECC now, will we have to start over when we move to S/4HANA?”
The answer is:
No – not if it is a true SAP-standard solution.
Modern SAP add-ons are designed so the transition from ECC to S/4HANA is straightforward. The technology is documented, the architecture is compatible, and the migration effort is minimal. For established providers like xSuite, this has been standard practice for years.
Meaning:
No duplicate work. No additional risk. No second project.
Instead, companies gain a valuable quick win rather than losing time in process optimization.
There is another important aspect that is often underestimated: An automation project for invoice processing not only improves daily operations – it strengthens the foundation for a successful S/4HANA transformation.
Why?
- Automation reduces manual steps
- Standardized AP processes reduce exceptions
- Structured digital workflows improve data quality and auditability
- AP staff gain capacity at the exact time they are most needed for the S/4 migration
The conclusion is clear:
Automation is not a competing project to S/4.
Automation strengthens S/4.
System integrators do crucial work. Without them, modernizing complex SAP landscapes would hardly be possible. They are indispensable for the overall transformation.
But for the specifics of financial processes, organizations need additional expertise. Finance teams in particular should not rely solely on the perspective of those who primarily view challenges through a systems lens.
For SAP invoice management, it pays to bring in specialized expertise – whether internal, through networks, or through established vendors such as xSuite that have spent years focusing exclusively on automating financial processes in SAP.
The S/4HANA migration is a major project – but it is not the only initiative that matters. Organizations that focus exclusively on S/4 risk missing the opportunity to quickly and sustainably strengthen their finance operations.
Automating AP invoice processing is one of the most powerful levers available. It offers:
- low effort
- significant cost and time savings
- rapid ROI
- no duplicate work during the later S/4HANA migration
In short: Everything points toward not postponing automation – but moving it forward intentionally.
