Initial situation
Changing the legal entity that invoices customers can trigger a chain of tax and systems consequences. The group had to address local VAT registration, intercompany stock movements, invoice numbering and document types, business-to-consumer sales, credit notes linked to earlier invoices and reporting fields affected by a VAT-rate change. A configuration error at go-live could have been repeated across a high volume of invoices and then flowed automatically into VAT returns and control reporting.
Our solution
We translated the new commercial model into a transaction-by-transaction VAT and accounting matrix, reviewing VAT identification data, credit-note logic, internal stock-movement documentation and the fields required for local reporting. Where the tax treatment required additional certainty, written clarification was sought from the Slovak tax administration. The resulting recommendations were then converted into practical instructions for invoicing and reporting system settings, including how different transaction types should appear in VAT records and the control statement.
Result
The group was able to implement the new sales model with a defined VAT treatment and documented system logic before transactions scaled up. That reduced the risk of systematic invoicing errors, inconsistent VAT reporting and expensive retrospective corrections, while giving finance and operational teams a common implementation blueprint.
