Complex VAT schemes break Business Central's standard VAT posting setup the moment you operate as a VAT group representative, apply reverse charge across entities, or trade in jurisdictions that mandate domestic reverse charge or split payment (PL, IT and similar). The standard VAT Posting Setup matrix and VAT Statement were not designed to consolidate multiple group members onto a single representative return, nor to validate that the correct reverse-charge VAT Business/VAT Product Posting Group combination was applied at the line level.

VAT Group & Reverse Charge Manager is a custom AL extension that ECOSIRE designs, builds, installs and supports on your own Business Central environment. It is delivered as a per-tenant extension (not a public AppSource listing), so the table extensions, page extensions, event subscribers and permission sets are scoped to your tenant and your chart of accounts, posting groups and company structure.

The extension extends BC's native VAT engine rather than replacing it: it consolidates submissions from group members into the representative company, drives reverse-charge and domestic-reverse-charge posting through configurable rules, models split-payment behaviour, and runs validation routines that catch mis-posted lines before they reach the VAT return. Where you already run multi-company or Dataverse/Power Platform integrations, settlement and reporting data is exposed through the standard BC API (OData/REST) so it can feed downstream reporting.

This is honest build-to-order software: scoped to your VAT schemes during discovery, built in AL, installed on your sandbox first, then promoted to production with your sign-off. ECOSIRE provides the source, documentation and ongoing support. Typical delivery is a few weeks depending on the number of jurisdictions and group members in scope.
