YITH WooCommerce Product Bundles is an extension conceived to create bundles of products of your shop. You can assign an ad-hoc price to the bundle or get it automatically calculated from the sum of single products in it.
Using YITH WooCommerce Request a Quote combined with YITH WooCommerce Product Bundles allows you to handle quotes even for bundles.
To enable the integration, you simply have to install and activate both plugins and set them up. Once ready, your customers will be able to add a bundle product to the quote and you’ll be able to regularly edit its price and make your offer.
