This has just come through , don’t know if it’s related ?! Possibly changing the total they are charging vat on (uk total vs eu sales total ?!)
We’re updating the European VAT Calculation Services Methodology policy to apply Business-to-Business (B2B) product-specific VAT calculations to certain types of listings across Amazon’s European stores.
Following the introduction of the EU B2B product specific VAT calculations, effective February 7, 2023, we’ll apply the product-related domestic reverse charge (0% VAT) to sales that meet the following conditions:
• Sale of electronic items subject to the product-related domestic reverse charge. These vary by country but typically include cell phones, computer chips, e-readers, laptop computers, tablet computers or video game consoles
• Domestic B2B sale
• Shipment value is above applicable thresholds (generally around EUR 5,000)
• Sale occurs in United Kingdom, Germany, Romania, Czech Republic, Austria, Denmark or Latvia
