WooPayments Not Updating Order Total After VAT Number Entry

Replies: 2

We are using WooPayments with WooCommerce EU VAT Number to apply reverse charge VAT for B2B sales. When a customer enters their VAT number, the cart updates correctly, and VAT is removed. However, the updated total is not passed to the payment gateway—WooPayments still processes the original amount with VAT included. This results in customers being charged the incorrect amount. It seems like the checkout updates the cart total but does not sync the new amount with WooPayments. Has anyone faced this issue, and how can we ensure WooPayments processes the correct, updated total?
