Yes. Well-placed upsells are one of the most reliable ways to lift average order value without acquiring a single new customer. The biggest impact comes from post-purchase upsells (after checkout) because there is no risk of cart abandonment.

ReConvert and AfterSell are the top-rated post-purchase upsell apps. For in-cart upsells, Frequently Bought Together and Bold Upsell are widely used. The planner recommends the best app for each upsell type.

An upsell on Shopify encourages the customer to buy a higher-value version of what they are already considering - for example, upgrading from a 100ml to a 250ml product, or choosing a premium bundle instead of a single item. A cross-sell instead recommends a complementary product that pairs with the item already in the cart - for example, a phone case suggested alongside a phone charger, or batteries alongside a device that needs them. Both increase AOV, but at different points in the journey: upsells work best on the product page and at checkout, while cross-sells work best in the cart and post-purchase, once the core purchase decision is already made. A common mistake is cross-selling on the product page before the customer has even committed to buying, which adds friction instead of value. ecomspy's Upsell Planner builds both into a single sequenced strategy so AOV is optimized at every stage of the purchase journey.

Product bundles increase Shopify AOV when three conditions are met: the bundled products are naturally used together, the bundle price offers a clear saving (10-15% is the sweet spot - larger discounts erode margin, smaller discounts don't motivate a purchase), and the bundle is presented as a named solution rather than a plain discount mechanic (e.g., 'The Morning Routine Kit' rather than 'Buy 3, Save 15%'). Framing matters because a named kit feels like a curated decision, while a generic discount feels like a markdown. Bundles with 2-3 products outperform 4+ product bundles because the perceived value calculation is simpler for buyers to judge at a glance. A common mistake is bundling slow-moving inventory together just to clear stock, which customers can usually tell isn't a genuine pairing. ecomspy identifies your top bundle candidates by cross-referencing which products are most frequently purchased together and which pairing maximizes margin per bundle.

A post-purchase upsell is an offer displayed to a customer immediately after they complete payment but before they reach the order confirmation page. Because the customer has just bought and their payment details are already saved, they can accept the upsell with a single click - no re-entering card information, no new trust decision to make. This meaningfully increases acceptance compared to pre-purchase upsells, since there's no new payment friction or second-guessing to overcome at that moment. A common mistake is offering an unrelated or overly expensive add-on here; the best post-purchase offers are small, logically connected to what was just bought, and priced low enough to be an easy yes. On Shopify, post-purchase upsells require a third-party app such as ReConvert, Zipify One Click Upsell, or AfterSell. ecomspy's Upsell Planner identifies your best post-purchase offer and generates the headline, benefit copy, and CTA for the offer card.

The best Shopify upsell apps by use case are: ReConvert (post-purchase upsells with a drag-and-drop thank-you page builder), Zipify One Click Upsell (post-purchase funnels with built-in A/B testing), Bold Upsell (pre-purchase product page and cart upsells), Frequently Bought Together (a cross-sell widget similar to Amazon's recommendation engine), and Monster Upsells (an in-cart bundle builder with a free shipping progress bar). For stores on a tighter budget, Shopify's native bundling features and the Shopify Subscriptions app handle basic bundle and subscription upsells without added app costs. A common mistake is running two overlapping upsell apps at once, which can create a cluttered or contradictory checkout experience for the customer. Before installing a dedicated app, check whether your current theme already supports basic upsell blocks natively, since many Shopify 2.0 themes do. ecomspy recommends apps based on your plan tier and upsell type so you don't end up paying for capabilities you won't actually use.

Upselling and cross-selling are one of the most reliable ways to increase Shopify store revenue without adding a single new customer, with the exact lift depending on your product catalog depth and the quality of your offer matching. Stores with 3 or more complementary product lines consistently see the highest AOV lifts, since there are more natural bundle and cross-sell combinations to surface at the right moment. For example, a post-purchase upsell accepted by just 1 in 5 buyers on a $25 add-on offer adds $5 to that order's AOV - on 1,000 monthly orders, that's $5,000 in additional monthly revenue at near-zero acquisition cost, since the customer was already going to buy. A common mistake is offering the same generic upsell to every customer regardless of what's in their cart. ecomspy's Upsell Planner calculates your specific AOV lift projection based on your current price points and estimated conversion rates before you implement anything.
