Why SAP enterprises are stuck between BRIM and S/4HANA

Growth doesn’t stall because enterprises lack systems. It stalls because revenue execution is trapped inside systems that weren’t designed for change.

The growth versus governance paradox

SAP-centric enterprises face a persistent dilemma. On one side, the business needs to launch new revenue models—usage-based pricing, hybrid offers, subscriptions, AI-driven services—faster than ever. On the other, governance requirements demand stability, compliance, and control.

SAP BRIM promises monetization flexibility, but in practice it is rigid, complex, and costly to adapt. S/4HANA migrations promise long-term modernization, but they stall under the weight of custom code, re-engineering, and unclear near-term ROI.

Enterprises are told to choose between speed and safety. In reality, they’re trapped between them.

Why revenue execution breaks inside ERP

The problem isn’t SAP itself. It’s where revenue logic lives.

Over time, pricing rules, approvals, bundling logic, entitlements, and workflows get embedded directly into ERP systems and tightly coupled extensions. Each change requires coordination across teams, testing cycles, and regression risk.

As a result:

  • Revenue logic becomes fragmented across systems

  • Innovation slows as change becomes expensive

  • Compliance risk increases as exceptions multiply

  • AI initiatives stall because execution isn’t deterministic or observable

ERP systems are excellent systems of record. They are not designed to be systems of rapid execution.

Clean core fails without an execution layer

Most S/4HANA programs now mandate a “clean core.” The intent is sound: reduce custom code, simplify upgrades, and lower long-term cost.

But without addressing revenue execution, clean core initiatives fall apart. Complex logic still has to live somewhere. If it’s pushed into BRIM, BTP custom builds, or recreated inside S/4, the core becomes polluted again.

Clean core is not achieved by deleting logic. It’s achieved by relocating it.

A clean ERP core requires a dedicated execution layer that can own revenue complexity without destabilizing systems of record.

The missing layer between ERP and growth

Revenue execution is the layer that translates business intent into consistent, governed behavior across systems.

When separated from ERP, this layer can:

  • Orchestrate pricing, bundling, approvals, and entitlements centrally

  • Unify fragmented revenue logic across channels and systems

  • Enable AI-driven decisioning without compromising control

  • Allow ERP to remain stable, compliant, and upgradeable

This is why speed to market is not an ERP problem. It’s a revenue execution problem.

Why replacing BRIM isn’t really about BRIM

Many SAP enterprises first encounter this problem through BRIM. BRIM becomes the visible bottleneck—the place where rigidity, cost, and complexity surface.

But BRIM is a symptom, not the disease.

The deeper issue is that revenue execution has been treated as a module instead of a capability. Replacing BRIM with another embedded solution doesn’t change the underlying constraint.

Enterprises need to move revenue execution out of ERP entirely—while keeping SAP as the system of record.

A different path forward

The enterprises that move fastest don’t rip and replace ERP. They decouple execution from it.

By introducing a revenue execution layer, they:

  • Replace BRIM’s rigidity without disrupting SAP

  • Achieve a truly clean core for S/4HANA

  • Launch new revenue models in weeks, not quarters

  • Prepare for AI and agentic commerce safely

  • Reduce long-term technical and migration risk

Revenue execution becomes a business capability, not an ERP customization.

Why this matters now

AI, usage-based pricing, and composable commerce are not future concepts—they’re board-level priorities. But none of them work if execution remains trapped inside legacy architectures.

SAP enterprises don’t need more modules. They need a new layer.

Revenue execution is that layer.
