WooCommerce

WooCommerce should natively support net product quantities and automatically calculated unit prices to help EU merchants comply with Directive 98/6/EC and national price indication rules.

Include net quantity fields, configurable comparison units, tax-inclusive calculations, product variations, sale prices, multipacks, product listings, WooCommerce Blocks, REST API and Store API support.

For example, a 100 ml product costing €10 should automatically display €100 per litre. Basic legally required product pricing information should not depend on a third-party plugin.
