Let’s talk about a phrase we’ve all heard in SAP projects: “That’s the SAP best practice.” It’s meant to close discussion. But often, it should do the opposite.
Best practices are foundational to SAP’s approach, predefined processes, templates, and accelerators designed to reduce risk, speed up delivery, and standardize core business operations. And yes, they bring value. But there’s a hidden trap here: treating “best practice” as a rulebook rather than a starting point.
That’s where the conversation around customization really begins.
Because in the real world, especially in complex, multi-country, compliance-heavy businesses, best practice doesn’t always fit. And forcing it can create more problems than it solves.
In this article from IgniteSAP we’ll explain why the smartest SAP consultants know that this isn’t a binary choice between “follow the template” or “rip it up and start again.” It’s about making informed, contextual decisions, and sometimes that means making changes.
Let’s start with the role of best practices. Tools like SAP Activate give us a head start, preconfigured content, fit-to-standard workshops, solution documentation. All of that saves time, helps clients visualize what “good” looks like, and provides governance-ready scope.
But those templates are drawn from averages. They represent what’s common, in the center of the bell curve, not necessarily what’s right for your client.
SAP itself has evolved its guidance to support this balance. Through the Activate methodology, SAP encourages a “fit-to-standard and fit-to-context” approach: starting with best practices, but adapting where genuine business needs justify it.
When a business needs to go beyond the default, due to local regulations, unique business models, or hybrid processes, that’s where customization becomes more than just a technical preference. It becomes a business necessity.
Take an example: a global manufacturer that needs to handle quality inspections differently across regions due to government mandates. Or a financial institution whose internal controls don’t map to SAP’s out-of-the-box approval logic. Or a startup scaling rapidly across countries, needing layered tax treatments SAP doesn’t natively support. These aren’t “preferences.” They’re business constraints, and trying to solve them purely with configuration may be inadequate or misleading.
Customization gets a bad rap in some circles. Rightly so, in cases where it’s excessive, undocumented, or poorly governed. But not all customization is bad. Some of it is essential.
What matters is why a custom approach is needed and how it’s delivered. The best SAP consultants don’t start with “we can build that.” They start with: “Is the need real? Is the value clear? Is the gain worth the complexity?”
Here’s where the discipline kicks in:
If a deviation reduces ten hours a week in manual corrections,
If it avoids fines for non-compliance,
If it increases user adoption and reduces support calls post go-live,
…then customization isn’t indulgence. It’s investment.
But not every adjustment carries the same weight. Some are just minor tweaks, custom print forms, smart screen layouts, dynamic approval rules. These can usually be handled with light technical effort and don’t impact upgrade paths much.
Others are more complex: building new user flows, creating custom Fiori apps, or rewriting pricing logic. These carry higher overheads, both in build effort and in lifecycle management. You need a way to assess that clearly, with your client fully informed.
Here’s the part many clients, and some consultants, miss: the nature of customization in SAP has changed, and is still changing, dramatically.
In the past, custom often meant core modification. Now, thanks to the SAP Business Technology Platform (BTP), event-driven architecture, and API-first design, you can build enhancements that extend SAP without compromising the core.
This is causing a strategic change in the way consultants practice their art:
You can build mobile apps that connect to SAP but run independently.
You can create lightweight business logic outside the main system that responds to real-world constraints.
You can automate decisions based on AI or external systems, without hacking the standard.
These are what we now call “clean customizations” or “standard-aligned extensions”. You get flexibility and maintainability, something that used to feel like a contradiction.
That’s why in 2025, the conversation isn’t really “customization vs standardization.” It’s “how do we extend the system in ways that make sense, with clear governance, measurable value, and minimal risk?”
The problems really start when best practice is applied dogmatically, when teams push the business to adapt to the system rather than using the system to serve the business.
This is common in design workshops. A business user starts describing how things actually work, and they’re met with, “Well, SAP doesn’t do that.” End of discussion.
But that’s the wrong mindset. The real question should be: Why does the process exist that way? What happens if it’s changed? Can the system support it in a scalable, compliant way, even if it’s not in the default template?
If that answer is yes, and the value is clear, then the right move isn’t “follow best practice.” It’s “make a responsible, well-documented adjustment to the standard practice.”
Customization is a business design decision, and the way we manage it determines whether it becomes a competitive asset or a long-term liability.
That’s why governance matters so much.
Projects that fail sometimes go off track because no one revisited a decision when the context changed. Or because a tweak was made quietly, never documented, and years later no one remembers why the system works that way.
To avoid that, high-performing SAP teams embed decision-making structures early. Every deviation from standard should be:
Classified: Is it low-impact config? Moderate complexity? High-risk architectural change?
Justified: Does it reduce cost, improve accuracy, or align with a legal requirement?
Tracked: Can we explain why it was done, who approved it, and what the fallback is?
The best teams don’t just track what’s different, they track the business case behind the difference. And they revisit it after go-live. Did the logic hold up? Is the customization still needed? Could it be replaced by standard functionality in a new release?
One of the smartest habits I’ve seen is the use of impact templates. These are simple tools that project teams fill in when a divergence from standard is requested. These outline: the technical complexity of the change, its impact on upgrades, testing, and support, and how it will be maintained over time.
These templates shift the conversation from preference to value. They also surface trade-offs that might otherwise go unexamined. If a change will increase test effort by 20% every upgrade cycle, is the business ready to own that? If yes, great. But let’s capture it.
This way, customization is driven by informed choice.
And the point isn’t to avoid customization altogether, but to do it on purpose.
Consultants often talk about design principles. But the most important principle is cultural: Design around the business, not the system.
That starts with listening. Too often, teams rush into configuration before really understanding what users do, how they decide, or what constraints they face. A process map isn’t enough. You need real-world stories, edge cases, and workarounds.
Take finance: many companies reconcile manually in specific ways because of audit expectations that aren’t reflected in standard content. Or procurement: regional buyers might require layered approvals based on ESG scores or local legislation. Or in manufacturing, sensor data might trigger events that fall outside SAP’s routing logic. These cases are the reality for many customers.
Designing for these realities isn’t rejection of best practice. It’s respect for the context.
One of the biggest breakthroughs in recent years is how modern SAP tooling has changed the risk profile of customization. With the ability to use BTP side-by-side extensions, SAP Build Apps for low-code design, and Cloud-native APIs and event connectors, it’s now possible to introduce business-specific logic without putting strain on the digital core.
That’s a massive shift. It means consultants no longer have to choose between “rigid standard” and “fragile custom.” There’s now a third path: smart extensions that meet the business where it is, without degrading system resilience.
But this flexibility only works if there’s discipline. The best consulting teams still impose constraints:
Custom behavior must live outside the core where possible.
All changes must be documented in a change log.
Lifecycle reviews must revisit every custom component.
Clients must understand what they’re approving, not just in delivery, but in ongoing ownership.
Let’s be honest: the word “customization” makes some clients nervous. It sounds expensive. Risky. Hard to manage. And sometimes, it is. But the problem isn’t the change itself, it’s how it’s explained.
That’s why experienced consultants present customization as a value choice. They use data that answers the following types of questions:
How many hours will this save?
What compliance risk does it eliminate?
How will it affect future rollouts, upgrades, or support?
They don’t pitch features. They frame decisions, and they include stakeholders in those decisions early. That way, the client isn’t just buying a system. They’re co-owning the outcomes.
And when clients are part of the choice, they’re far more likely to support it when things get tough. You’re not seen as the vendor who delivered the problem. You’re seen as the partner who managed the trade-off.
A key part of delivering value is helping clients understand the difference between technical customization (which may carry lifecycle costs) and strategic customization (which delivers long-term business advantage). The earlier these conversations happen, the more aligned and confident the client becomes in owning those decisions.
So here’s where we land.
“Best practice” isn’t a fixed set of templates. It’s a mindset: start standard, ask hard questions, and adapt based on evidence, not guesswork or habit.
Standardization is useful. But SAP projects don’t succeed because they’re neat and tidy. They succeed because they work for the people using them. And that often means careful customization.
The skill of an SAP consultant isn’t in saying yes or no to a change from standard. It’s in knowing which deviations create value, and how to deliver them responsibly.
Projects don’t go wrong because they custom-built a vendor screen or added a smart tax workflow. They go wrong because no one managed the complexity that came with it.
Manage the complexity. Show your work. And most of all, listen.
That’s the future of SAP consulting: contextual, governed, and built for real business.
