Discount Codes and Gift Cards Now Split by Tax Class in Multi-VAT Orders

Overview

AI Commerce now shows discount codes and gift cards split by tax class when the same discount applies to items with different VAT rates.

If an order contains products from multiple VAT classes, the discount is shown on separate rows for each rate — for example CODE123 (25.5%) and CODE123 (14%). Orders with a single tax rate continue to show one discount row as before.

This makes the VAT allocation visible per tax class and keeps order totals, invoices, and ERP exports correctly aligned.
