Shopify recommends products for free, but only one of the two kinds it supports is automatic. The "related" kind, the substitutes that sit under a heading like "you may also like", are generated for you from purchase history, falling back to product descriptions on English storefronts and then to collections. The complementary kind, the add-ons that make up a genuine frequently-bought-together block, are never generated at all: every pairing is chosen by hand, one product at a time.

The second gap is that a native recommendation is inert. It hands the theme a list of products and nothing else, with no bundle price, no discount and no way to add the whole set to the cart in one action. Those are the two things this category is really selling: pairings nobody had to sit and choose, and the checkout mechanics that make accepting one a single click.

What to look for in a Cross Selling app

Whether you have the history to recommend from: Purchase-history recommendations need previous sales to learn from, and orders imported from another platform are not counted. A store that has just migrated is starting blind, which is exactly when an app's own engine is worth paying for, and also exactly when it has no more to work with than Shopify does.
Automated pairing, or a nicer way to pair by hand: Both exist in this category and they are priced as though they were the same thing. If your catalogue is small and stable, a good bulk editor over the native complementary field may be all you need. If it turns over constantly, hand-picking is the thing you are trying to escape, so make sure that is what you are buying.
The discount is most of the product: Since the native version cannot price a bundle at all, the offer logic is the real purchase: how the discount is expressed, and how it behaves next to the other promotions you run. Ask what happens when a customer already holds a code, because that is where these quietly disagree with each other.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
