Admin Order Modifier for WooCommerce

Admin Order Modifier for WooCommerce lets you edit order line item prices in the admin with tax or VAT included, instead of the tax-exclusive editing WooCommerce has by default. It adds Cost (Incl.) and Total (Incl.) columns to the order edit screen: you enter the final price and it works out the base price and tax.

It covers product line items, custom fees, shipping items and refunds, and works with multiple tax rates. You can edit unit costs, drag line items into a new order that carries into customer emails and invoices, and view or set discounts as a percentage. A Quick Apply button fills in the product's current regular or sale price.

You can switch the modifier off for single items, such as non-taxable ones. The order needs at least one tax rate applied. It works with HPOS.
