Data‑Driven Tax in Dynamics 365: Getting It Right the First Time

E‑invoicing and real‑time digital reporting are embedding tax compliance directly into finance processes and ERP transactions. With global mandates accelerating and the UK set to introduce e‑invoicing from 2029, Dynamics 365 Finance can no longer rely on post‑period corrections or manual controls.

This session explores how e‑invoicing and digital reporting requirements impact core finance processes in Dynamics 365: from invoicing and posting through to reporting, cash flow and audit defence. It highlights common breakdowns seen in ERP environments, including master data inconsistencies, invoice design issues and delayed error detection.

Using a “getting it right the first time” mindset, the session shows how increased automation and emerging AI‑enabled checks within ERP can help identify data issues earlier, reduce rework and support real‑time compliance as tax authorities move faster and closer to transaction data.
