Best Shopify apps to increase average order value in 2026: 14 apps for 7 jobs

How we picked them

• Native first. Where Shopify does the job free, we say so before naming an app.
• One job each. A cart drawer is compared with cart drawers.
• Official listing, and a way to try it. Every app has a free plan or trial.
• The meter is named. Orders, credited revenue, upsell revenue, bar views or a flat fee.

Facts come from Shopify's Help Center, each app's listing and the vendor's pricing and help pages. We checked them on 11 October 2026. We left prices out. For six of the fourteen apps, the listing and the vendor's site showed different tables. The live page beats a number that is already wrong. We have no commercial relationship with any app here.

The fourteen apps at a glance

Cart upsells: the last look before checkout

A slide-out cart keeps the shopper on their page. It gives you one small panel to suggest what goes with the item. Keep the suggestion cheaper than the item and clearly related. Next to a phone, suggest a charger. A second phone is the wrong idea.

Upcart

Upcart replaces the theme cart with a drawer. The drawer carries upsell blocks, a rewards or free-shipping bar, add-ons and announcements. Rokt now owns it. Rokt announced its acquisition of AfterSell, Upcart's maker, in January 2024. Paid tiers come with a free trial and are priced by monthly store orders. High-volume stores pay usage fees on top. Several unrelated apps share the name. The one we mean is listed as "Upcart—Cart Drawer Cart Upsell".

Monster Cart Upsell+ Free Gift

Monster Cart does a similar job with a focus on reward bars. The cart unlocks a free gift, free shipping or store credit as it grows. It also has one-tick add-ons and "buy more, save more" widgets. There is a small free plan and a trial on paid tiers. The bill is a base fee by store orders plus usage charges. The developer confirms this in replies to surprised merchants. Read that part of the listing twice.

Bundles: sell the set

Bundles work when the items are used together. A good bundle saves the shopper a decision as well as money. Start with Shopify's app for fixed sets. Move to a third-party app when you need mix-and-match.

Shopify Bundles

Shopify's free Bundles app builds fixed bundles and multipacks from your stock, on every plan. Know its limits before you plan a promotion. It has no mix-and-match, and bundles cannot contain bundles. The bundle price does not follow a component's price change. Bundles cannot be used in exchanges or with subscriptions. It also needs Shopify's upgraded checkout.

Fast Bundle

Fast Bundle adds what Shopify's app leaves out. Mix-and-match bundles, frequently-bought-together blocks and upsells. It is free while bundle revenue is low, and it has a free trial. Paid tiers are set by monthly bundle revenue. So a successful bundle moves you up a plan. Its listing and pricing page showed different tiers when we checked. Go by the listing you install from.

Volume discounts: buy two, save more

Quantity breaks suit consumables and gifts: socks, coffee, candles. One platform detail matters. Shopify's built-in quantity price breaks exist only inside B2B catalogs. A retail store that wants "buy 2, save 15%" still needs an app.

Kaching Bundles

Kaching Bundles puts quantity breaks, buy X get Y and bundle offers on the product page. It offers a free trial. The bill is based on extra revenue the app credits to itself. So it grows as the offers work. That is fair in principle. Just know the meter is the app's own attribution, which may differ from your accounts.

Bundler

Bundler has a real free plan with unlimited orders. It covers volume discounts, buy X get Y and auto-applied discounts. Mix-and-match bundles, landing pages and analytics are on flat-fee paid plans. The developer cut prices in 2026. Existing subscribers kept the old price until they re-subscribed. Check what you actually pay.

Free-shipping bars: show the gap

The free-shipping threshold is built into Shopify. Use an automatic free-shipping discount with a minimum amount or quantity. Or set a free shipping rate over a set amount. The threshold counts product prices only. Tax is excluded. A progress bar app only shows the gap, like "$12 away from free shipping". If the rule is missing in Shopify, the bar promises something checkout will not deliver. Set the threshold a little above your typical order.

Hextom Free Shipping Bar

Hextom's bar is the long-standing choice. It is a progressive banner with a free plan and a flat-fee Premium tier. The free plan allows one bar. Targeting by Shopify Markets and automatic currency conversion are Premium only. That matters if you sell in more than one currency.

Essential Free Shipping Upsell

Essential Free Shipping Upsell was renamed from Essential Free Shipping Bar. It pairs the goal bar with cart and product-page upsells. So the bar can suggest the item that closes the gap. It has a free plan. Paid plans count bar views, whatever your orders do. A busy store that converts slowly pays more than its sales suggest.

Post-purchase offers: the order after the order

A post-purchase offer appears after payment and before the confirmation page. Accepting it takes one click and no new card details. Shopify allows it on Basic and higher plans. Offers inside the checkout steps need Shopify Plus. Three platform rules apply whichever app you choose. Only one post-purchase app can be active at a time. The order shows as on hold while the offer is on screen. Offers appear only in the store's default currency. Shoppers paying in another currency do not see them.

Aftersell

Aftersell is also owned by Rokt. It runs one-click post-purchase offers and thank-you page upsells. Plus stores also get checkout upsells. It offers a free trial. Billing counts every store order in the last 30 days, offer or no offer. Switching widgets off does not stop the charge. Trust its billing documentation. The pricing page and listing have shown different figures.

Zipify OneClickUpsell

Zipify OneClickUpsell does post-purchase upsells and downsells. It also offers pre-purchase, cart and thank-you offers. It has a free plan. Paid tiers are set by the upsell revenue it generates. It allows at most two post-purchase offers per order. You must select it as the active post-purchase app in Shopify's checkout settings.

Recommendations: what goes with this

A product page that suggests the matching item works like a good shop assistant. Hand-pick pairings for your best sellers. You know the trousers go with the jacket.

Shopify Search & Discovery

Shopify's free Search & Discovery app lets you pick products for each product page. You can choose up to ten complementary and ten related products. Use them alone or mixed with Shopify's automatic picks. The complementary block needs a compatible theme. Only one can sit on a product page. A complementary product only shows while it is in stock.

Frequently Bought Together

Code Black Belt's Frequently Bought Together adds the familiar "bought together" bundle widget. It suggests pairings with AI and can add a bundle discount. The free plan is capped at three manual bundles. Paid tiers have a free trial and are priced by store orders.

Where Idukki fits (ours)

We make Idukki, so weigh this accordingly. A customer photo often shows several products: the jacket, the bag, the shoes. Idukki lets you tag each one on the post. The shopper adds them to the cart from the photo, on the same page. The recommendation is visible on a real person. It sits alongside the apps above. More in visual search and shop the look.

Free gifts: a reason to reach the next tier

A free gift above a spend threshold works like a free-shipping bar, with something to unwrap. Pick a gift people want. It should cost less than the margin on the extra spend. Show the threshold in the cart.

BOGOS

BOGOS adds free gifts automatically, plus buy X get Y offers and bundles. Its free plan covers 30 orders in total. The allowance does not reset monthly. Paid tiers are set by monthly orders and matched to your Shopify plan. Each order above the allowance costs extra. Checkout upsells are on its Plus tier only.

Gift Box

Digismoothie's Gift Box handles gift with purchase and spend-threshold gifts. It has a short free trial and no free plan for a live store. Paid tiers are set by monthly online store orders.

Where to start

1. 1Measure today's AOV and median order in Shopify Analytics.
2. 2Set a free-shipping threshold a little above your typical order. Show it in the cart.
3. 3Hand-pick complementary products for your top ten sellers in Search & Discovery.
4. 4Add one paid app for the job your data points to. Bundles, volume breaks or post-purchase offers.
5. 5Run it for a few weeks before adding the next. Check the bill against what the app says it earned.
