Current rollout dates: this article discusses Budget 2025/26 planning. For the published stages and business notification requirements, see the MRA e-invoicing deadline timeline, updated on 21 October 2026.
Budget-driven phase expansion means more suppliers need to move quickly from planning to implementation. The teams that perform best are the ones that lock ownership, clean core data, and run test-first workflows before deadlines become urgent.
Where to Focus First
The first decision is ownership. A successful rollout needs one accountable owner across finance, operations, and IT so decisions do not stall. After ownership is clear, the next priorities are data quality and testing discipline, because most early failures come from these areas rather than from core software capability.
Teams should validate customer and tax master data before integration testing, and define how rejected or amended invoices are corrected. Doing this early reduces pressure during go-live and gives staff a clear way to respond when exceptions appear.
Common Mistakes to Avoid
The biggest risks are starting too late, assuming technical connectivity is enough without user training, and neglecting post-go-live portal reconciliation. A connection can be live while operations are still fragile. Stable compliance requires both a working system and a disciplined operating routine.
