Delta Fiscalization System — certified by two national tax authorities

Every invoice had to reach the tax authority correctly and on time, or the business carried compliance and penalty risk. I took the system from inception and prototype through build, testing and launch, connecting SAP business transactions to Zimbabwe's FDMS and Zambia's VSDC smart-invoicing systems.

90%+ faster transaction processing
Stack
SAP S/4HANA, Integration services, FDMS, VSDC

Context

Zimbabwe and Zambia both require businesses to fiscalise invoices through the revenue authority’s systems — FDMS for ZIMRA, VSDC smart invoicing for ZRA. For a multinational billing at Delta’s volume, any gap between what SAP records and what the tax authority receives is a compliance failure, and failures carry financial penalties.

My role

I owned the system end to end: technical feasibility, architecture, prototyping, build, testing and launch, working with finance operations and IT stakeholders throughout.

Approach

  • SAP as the source of truth. Business transactions originate in SAP and are carried through the fiscalization integration to FDMS and VSDC.
  • Two jurisdictions. The system meets both ZIMRA and ZRA requirements.
  • Certification as the acceptance test. The system was built and tested against each authority’s certification process, not just internal sign-off.

Outcome

  • Certified by both the Zimbabwe Revenue Authority (ZIMRA) and the Zambia Revenue Authority (ZRA).
  • Removed a significant regulatory-compliance and financial-penalty risk.
  • 90%+ improvement in transaction processing efficiency across finance operations.
