I sell some products that are eligible for the VAT Margin Scheme (you can read about that here - https://www.gov.uk/vat-margin-schemes)
With these, tax is not calculated on the selling price, but on the profit of the product.
So for example, If I bought something at £100 and sold at £220, profit would be £120 and tax would be £20
I have ‘Cost’ field on all my products so I can enter the original purchase price in Shopify.
Is there any way, or any app for Shopify that can add tax to the product based off a percentage of the cost field for that product?
Has anyone got any ideas of best way to implement? VAT Margin Scheme is used by many businesses including car dealers, antique dealers, art gallery owners, etc so I am sure it would be a very useful add on.
