Substitute products
Substitute products are products a customer can buy instead of another because they meet the same need, such as tea instead of coffee or another brand of the same item.
What is Substitute products?
Substitute products are products a customer can buy instead of another one because they meet the same need, such as tea instead of coffee or one brand of running shoe instead of another. When the price of one rises or it sells out, demand shifts to its substitutes. In ecommerce, a substitute is the alternative you show when the primary product is out of stock, discontinued or too expensive for the shopper. That makes it different from a complementary product, which is bought together with the primary one, like a phone case with a phone. Good substitutes match on the attributes that matter for the purchase: product type, size, compatibility and price range. Showing one keeps a sale that a sold-out page would lose; estimate what those lost sales cost with the free stockout loss calculator.
Why Substitute products matters for e-commerce
A shopper who lands on a sold-out product page will usually leave unless the page offers a good alternative. Substitutes keep that visit useful: a "similar products" block, an "also available in" note or a replacement suggestion on a discontinued product page gives the shopper a next step. Substitutes also explain price sensitivity. When close alternatives exist, a price rise sends buyers to them, so knowing which products substitute for each other helps with pricing and with deciding which items must never run out. All of this depends on product data: alternatives can only be matched when product type, size, compatibility and other key attributes are filled in the same way across the catalog.

Common mistakes with Substitute products
- You lose sales when you do not suggest alternatives for out-of-stock items. This frustrates customers and makes them leave your store.
- Showing items that do not match the customer's needs or budget is a mistake. Wrong suggestions confuse shoppers and stop them from buying.
- Do not suggest substitutes that are also out of stock. Recommending items with long shipping times also creates a bad experience for the customer.
- Offering too many choices makes it hard for customers to decide. This often causes them to leave your site without buying anything.
- Customers need to know why they see certain items. Always label substitutes clearly so shoppers understand they are looking at alternatives.
Tips for Substitute products

- Connect your suggestions to live inventory data. Only show products that are in stock and ready to buy.
- Limit the list to three or five items. Too many choices can confuse shoppers and prevent a purchase.
- Use clear headings like "Similar Items" or "Other Options." These labels help shoppers understand why they see these products.
