- Last update: 01. June 2026
- Compatibility: 6.7.*
Overview
Description
The perfect product match. More revenue. A better shopping experience.
Present matching complementary products right at the moment of purchase. Your customers select relevant items with just one click and add them to the cart together with the main article – no detours, no page switches.
About the extension
The Cross Selling: Accessories & Complementary Products plugin extends the Shopware 6 product detail page with a prominently placed accessory block. All complementary products assigned by the shop operator are shown at a glance – with image, name, price and optional short description. Accessories are picked via checkbox and added automatically when the customer clicks "Add to cart".
The total price of main item and selected accessories is calculated live. A breakdown as well as a notice on tax and shipping costs in line with German price regulations are directly integrated – including a link to the shipping and payment information page.
Direct integration
Allow your customers to put matching complementary products into their cart directly from the product page – no detours needed. The accessory block integrates seamlessly into the existing theme and can be placed either above or below the add-to-cart button.
Flexible customisation
Adapt the product recommendations to your own ideas to achieve an optimal integration with your marketing strategy. Choose between list and grid layout, three box styles (border, shadow, no frame) and three image sizes. Unit prices and product images can optionally be shown or hidden.
