DuoCart — Multi-Variation WooCommerce Plugin

DuoCart replaces WooCommerce’s default single-variation flow with a powerful multi-row interface. Shoppers configure multiple variations, adjust quantities, and add everything to the cart in a single AJAX action — no page reloads, no back-and-forth.

What is DuoCart?

If you sell variable products on WooCommerce, your customers are forced to select one variation at a time, add it to cart, go back, select another, and repeat. DuoCart eliminates that friction entirely. It hooks into your product pages and replaces the standard form with a dynamic multi-row selector — letting shoppers build their full order in one place and check out faster.
