What Is a Complementary Product in Shopify?
A complementary product is an item that customers often purchase alongside a selected product. Unlike alternatives or similar products, complementary products enhance or complete the main product’s use or appeal.
For example, if you sell cameras, complementary products might include lenses, batteries, or carrying cases—items that naturally pair well and add value to the purchase. Offering complementary products helps customers discover useful add-ons, improves their shopping experience, and importantly, increases your average order value.
How to Choose Complementary Products
Choosing the right complementary products requires thoughtful selection:
- Recommend items your customers genuinely find useful alongside the main product.
- Opt for products that serve as a natural “add-on” to the original purchase.
- Select products that are either lower in cost or equivalent to the main product to encourage easy upsells.
When done right, complementary products feel helpful rather than pushy, making customers more likely to add them to their cart.
Complementary Products vs. Related Products: What’s the Difference?
Many store owners confuse complementary products with related products, but they serve different purposes:
- Complementary Products: These are supplementary items designed to enhance the primary product experience. The goal is to encourage additional purchases that complete or improve the original product usage. Selection can be manual or data-driven based on customer buying habits.
- Related Products: These are items that belong to the same category or share similar features, aimed at giving customers alternative or upgraded options. Related products often appear automatically based on product tags, categories, or algorithms.
Example:
- If you are selling a t-shirt:
- Complementary products: jeans or matching shoes
- Related products: other t-shirts in different colors or styles
Understanding this distinction lets you strategically design product recommendations that maximize conversions and customer satisfaction.
