# How to solve – “Customer VAT does not match company VAT”

## The VAT setup used by the default customer does not match the company’s VAT configuration.

1. Open the default customer in Business Central and check its **VAT Bus. Posting Group**.
2. Open **VAT Posting Setup**.
3. Find the combination of the customer’s **VAT Bus. Posting Group** and the relevant **VAT Prod. Posting Group**.
4. Confirm that the VAT percentage is correct.
5. In the Admin Center, open **Integration → VAT groups** and verify that the rate matches Business Central.
