What delocalisation means for implementation and upgrades

2025-11-18TD SYNNEX

What is delocalisation?

Why Microsoft made the change

Benefits for multi-entity UK businesses

  • Simpler upgrades: Because localisation is now an extension, upgrades to the core Business Central application are less likely to be delayed by country-specific changes. This reduces downtime and keeps systems current.
  • Consistent compliance: Extensions maintained by Microsoft ensure that VAT, MTD and CIS features are always up to date with HMRC requirements. Businesses no longer need to worry about custom code breaking during upgrades.
  • Flexibility for multi-entity setups: Each UK entity can enable the localisation extension independently. This is useful for groups with mixed operations, such as one entity needing CIS compliance while another does not.
  • Reduced customisation risk: Extensions are designed to work alongside other apps without modifying the base code. This lowers the risk of conflicts during upgrades and simplifies support.
