Critical Decision Factors
Custom Add-on Trap #1: Country Proliferation
The Problem:
2026: 12 new countries mandate e-invoicing quarterly. Custom dev = €1.2M per country x 12 = €14.4M backlog.
DRC Advantage:
- 60+ countries pre-built
- Quarterly content updates included
- Zero per-country development
- Day 1 compliance everywhere
Custom Add-on Trap #2: S/4HANA 2027 Migration
The Problem:
Custom ABAP/IDOC solutions fail 95% S/4HANA compatibility. €3.8M rewrite during 2027 ECC sunset deadline.
DRC Native Architecture:
- 100% S/4HANA compatible
- BRF+ replaces custom logic
- Zero migration rework
- Fiori apps Day 1 ready
Executive Recommendation
Migrate custom add-ons to SAP DRC before Q4 2026. €4.2M 5-year TCO savings, 100% S/4HANA readiness, 60+ countries Day 1 compliance. Custom development dead post-ViDA 2026.
