A customer orders 1.3 of fabric using a global increment of 0.1.
Let customers order quantities such as 0.5 or 1.3. Set a shared quantity increment and minimum for your catalogue, while keeping accessories in whole units.
The free version includes:
For example, an increment of 0.1 and a minimum of 0.8 allow 0.8, 0.9, 1, 1.1 and so on, subject to available stock. Customers can also edit decimal quantities directly in the cart and update their totals.
The Pro version is a separate add-on. It adds decimal quantities for selected products in an otherwise whole-quantity catalogue, plus custom increments, minimums and maximums for each product or variation. The free version remains installed and provides the shared WooCommerce engine.
