The app doesn’t manage VAT.
However, please note that our team is actively involved in migrating our Wholesale Pricing Discount app from utilizing the Shopify Asset API to adopting the Theme App Extension. This transition will offer us a much easier and convenient approach to interact with Shopify Markets which will allow us to offer support for many multi-currency and tax related requirements.
In the meantime, we can offer to add a manual customization on the cart page to show a breakdown of tax exclusive cart total, tax amount and the tax inclusive cart total. Please note that this manual customization will only apply on the subtotal of the cart page and will only be for display purposes. If you'd like to get this customization for your store, please send us an email at themes@wholesalehelper.io along with your tax percentage for B2B customers.
