The shipping price paid by your customers is pulled automatically from your store and already includes tax/VAT.
You can view the shipping tax paid for each order on your Orders page by hovering over the Tax amount of an order:
If you want to include Tax/VAT in the shipping cost paid by you (the merchant), you can do so manually:
Navigate to Settings ➡️ Costs ➡️ Fulfillment
Edit your existing profile
Include the tax amount in the value you enter under Shipping Rate in the applicable shipping profile, then click Done
⚠️ Please note that BeProfit does not offer a breakdown of your shipping costs, separating them into shipping and tax amounts.
