The UK’s long‑awaited e‑invoicing mandate is officially on the horizon, with structured electronic invoicing set to become mandatory for VAT‑related B2B and B2G transactions from April 2029. While the deadline may seem distant, in our experience finance teams are better starting their preparation early to avoid the bottlenecks and data challenges seen in other countries’ rollouts.
The mandate will require invoices to be exchanged in structured, machine‑readable formats, enabling automated processing and reducing the UK’s £10bn VAT gap. HMRC has confirmed that existing VAT invoice requirements will remain, but the way invoices are transmitted and validated will fundamentally change. Businesses will need clean, complete data and digital workflows capable of handling structured formats reliably.

Why early preparation matters
Our experience shows that organisations who delay working on projects like hthis face the steepest challenges. Countries such as Poland and Belgium have already demonstrated that onboarding suppliers, cleansing data, and redesigning approval workflows can take months - not weeks.
