The current OTA rollout information places government institutions and entities in Phase 4. The published timeline says Phase 4 will begin in February, but the year has not yet been announced.

Therefore, it would be misleading to state that B2G e-invoicing becomes mandatory in April 2027. The current official Fawtara FAQ does not provide April 2027 as the B2G implementation date.

B2G transactions are part of the Fawtara operating model, but the government-entity rollout has its own phase.

Key points

  • B2G is included in the Fawtara programme.
  • Government institutions and entities are assigned to Phase 4.
  • Phase 4 is currently stated to begin in February, with the year yet to be announced.
  • April 2027 is not the current official B2G deadline.
