The Best Shopify Upsell Apps: Start With the Free Tier and Count the Orders

Start with the free tier and count the orders. ReConvert is free up to 50 orders a month and handles post-purchase and thank-you page offers, and Frequently Bought Together is free up to 3 bundles and handles cross-sells on the product page. Both have paid plans from about 10 to 15 dollars a month. The app that wins is the one whose free tier covers your volume and whose offers show up where your customers actually decide, not the one with the longest feature list.

The upsell app is the one app decision that repays measuring, because it sits on the two pages where money changes hands: the product page and the thank-you page. It is also the decision most stores make by reading a list of features instead of counting orders, and the feature list is the wrong document.

The average Shopify store runs 5.6 apps, and stores under 1 million in revenue typically spend 50 to 300 dollars a month on apps, with a midpoint around 175. Six apps at 20 dollars each is 120 dollars a month before you have sold anything. So the free tier is not a trial concession here. For a small store it is the difference between a stack you can afford and one you cannot, and the upsell app is where that math is most visible.

ReConvert and Frequently Bought Together, on the numbers

ReConvert, now Upsell.com, is the post-purchase app. Its free plan covers up to 50 orders, and the paid plan starts at 9.99 dollars a month. It puts offers on the thank-you page and in post-purchase flows, which is the moment the customer has already paid and is most likely to say yes to one more thing. That placement is the whole argument for it. The customer is not deciding whether to buy. They already bought. They are deciding whether to add.

Frequently Bought Together is the product-page app. Its free plan covers up to 3 bundles, and the paid plan starts at 14.99 dollars a month. It puts a bundle box on the product page, usually a main product with one or two companions, with a single add-to-cart. The free tier is thin, three bundles, which means a store with more than a handful of products outgrows it fast. But for a store with one hero product and two natural companions, three bundles is exactly enough, and the app costs nothing until the catalog grows.

What the free tier hides, and the script weight nobody checks

Every free plan on this list has a number where it stops, and that number is what decides whether the app is genuinely free for you. ReConvert stops at 50 orders. Frequently Bought Together stops at 3 bundles. Judge.me, the reviews app most of these lists recommend alongside upsells, is unlimited on reviews but locks 63 features on its 15 dollar Awesome plan, including reminder emails. Read the free plan's limit before you build on it, because most stop at a set number of orders, page views, or extra revenue a month.

The second check is script weight. An upsell app injects JavaScript onto your product page and your thank-you page, and a heavy app slows the pages that make you money. Check the app's footprint before you install it, and check it again after a month of orders. An upsell that adds 2 percent to conversion and 400 milliseconds to load time is a trade, not a win, and the stores that never measure it are the ones paying for it in bounce rate. If the app slows the store down or leaves code behind after uninstall, that is a warning, not a footnote.

The test that decides it, in one week

Install one app, not two. Run it for one week on real orders, with the offer on one placement only, and measure three numbers: take rate, revenue per session on the pages where the offer appears, and load time on those pages. If take rate is under 2 percent after a week, the offer is wrong, not the app: change the product, the price, or the placement before you change the app. If revenue per session rises and load time does not, keep it and pay for it when the free tier runs out.

What usually fails is stacking two upsell apps at once. The product page ends up with a bundle box and a pop-up and a thank-you page offer, and customers stop clicking any of them. One offer per page, one app, one week, three numbers. That is the test, and it is cheaper than the argument about which app is best in the abstract.

Frequently asked questions

What is the best free Shopify upsell app?

ReConvert is free up to 50 orders a month and handles post-purchase and thank-you page offers, and Frequently Bought Together is free up to 3 bundles for product-page cross-sells. Which is best depends on where your customers decide: after purchase, or on the product page.

How many orders does ReConvert cover on its free plan?

Up to 50 orders. After that the paid plan starts at 9.99 dollars a month. If you do fewer than 50 orders a month, the free tier covers you completely, which is why it is the default pick for new stores.

Do upsell apps slow down a Shopify store?

They can. An upsell app injects JavaScript onto your product and thank-you pages, and a heavy app adds load time to the pages that make you money. Measure load time before and after install, and uninstall cleanly if the app leaves code behind.

Should I run two upsell apps at once?

No. One offer per page, one app, one week of measurement. Stacking a bundle box, a pop-up, and a thank-you page offer at the same time made customers stop clicking any of them in our test. Change the offer before you change the app.
