Cheapest Shopify upsell app in 2026: ranked by real entry cost, not just the sticker
The cheapest Shopify upsell app by entry price is ReConvert at $4.99/mo, followed by Zipify OCU (around $8, verify the current tier), Selleasy ($9), Ultimate Special Offers ($9), In Cart Upsell ($9.99) and Bold or CartHook ($10). But here is the thing the price-comparison lists miss: for several of these apps, the sticker price is not the whole cost. A few of the cheapest-looking apps charge you more as they earn you more, because their pricing scales with your upsell revenue or takes a percentage of it. So the app with the lowest entry number can quietly become the more expensive one once it actually works, while a flat-price app that looked pricier stays put. Below we rank by real entry cost from live App Store data (July 2026), and for every app we show the pricing model, not just the sticker. We did not hands-on test these apps, and we say so.
Cheapest close runners-up: Zipify OCU (~$8, verify the tier), Selleasy ($9), Ultimate Special Offers ($9), In Cart Upsell ($9.99), Bold and CartHook ($10).
Cheapest that stays cheap at scale: a flat-price app like Also Bought ($19.99/mo) can end up cheaper than a $5 app whose cost scales with your upsell revenue.
The honest caveat: read the pricing model, not the sticker. ReConvert and Zipify tiers scale on upsell revenue; Bold, CartHook and Ultimate Special Offers take a percentage of upsell revenue. The "cheapest" app can become the priciest once it works.
The cheapest upsell apps, ranked by real entry cost
Here is the field sorted by entry price, with the pricing model beside it so the sticker cannot mislead you. Note the fourth column: "scales with revenue?" is the whole point of this page. An app that costs a cut of your upsell revenue starts cheapest and gets pricier exactly when it starts working, so a flat-price app can be the better deal at volume.
| App | Entry price | Pricing model | Scales with revenue? | Funding |
|---|---|---|---|---|
| ReConvert | $4.99/mo | order / upsell-revenue tiers | Yes · tier caps track upsell revenue | bootstrapped |
| Zipify OCU | ~$8/mo* | scales with upsell revenue | Yes · directly | bootstrapped |
| Selleasy | $9/mo | order-volume tiers | Indirect · by order count | bootstrapped |
| Ultimate Special Offers | $9/mo | $9 + 1% usage (cap $10/order) | Yes · 1%, capped per order | bootstrapped |
| In Cart Upsell | $9.99/mo | order-volume tiers | Indirect · by order count | bootstrapped |
| Bold Upsell | $10/mo | percentage of upsell revenue (2.5% paid) | Yes · a direct cut | bootstrapped |
| CartHook | $10/mo | order tiers + 1% revenue share | Yes · 1% on top | declining |
| Also Bought | $19.99/mo | flat monthly | No · flat, stays put | bootstrapped |
*Zipify OCU entry is around $8/mo, lower than its historical pricing; verify the exact current tier on its App Store listing before you rely on the number.
The revenue-scaling trap (read this before you pick on price): the four cheapest apps here are cheapest partly because their cost is tied to your success. ReConvert and Zipify OCU tiers scale on upsell revenue; Bold takes a percentage of upsell revenue; CartHook adds a 1% revenue share; Ultimate Special Offers adds 1% usage on top of its $9 base. That is not a scam, it is a business model, but it means the sticker price tells you the cost when the app does nothing. Once it earns, your bill rises with it. A flat-price app such as Also Bought ($19.99/mo) looks more expensive on day one and can be cheaper by the time your upsells are actually producing. Rank on the model, not the number.
The cheapest picks, with the catch on each
The cheapest sticker is not the cheapest bill. Several budget upsell apps charge a cut of the revenue they earn you, so the price you compare on day one is the price when the app does nothing.MerchantStack true-cost method
When a "pricier" flat app is actually cheaper
If your upsells are already producing, do the arithmetic on the model rather than the sticker. A percentage-of-revenue app such as Bold Upsell (a 2.5% cut on the paid plan) or CartHook (a 1% revenue share on top of its tier) charges you in proportion to what it earns, forever. A flat-price app such as Also Bought ($19.99/mo) charges the same whether it earns you $100 or $10,000 a month. There is a crossover point where the flat fee becomes the smaller number, and for a store doing meaningful upsell volume it can arrive fast. Bundle tools price the same way: Wide Bundles ($14.99, flat tiers) and Frequently Bought Together ($14.99) charge by tier rather than by a slice of your revenue. The same logic favors order-volume tiers (Selleasy, In Cart Upsell) over pure revenue-share for a store that expects its upsells to work. Cheapest to start and cheapest to run are different questions, and the second one is the one that shows up on next quarter's bill.
The genuinely cheaper-than-cheap options (and their real cost)
Two ways exist to pay even less than $4.99, and both have a cost that is not on the invoice. First, most of these apps run free on development stores or offer an order-capped free tier (Selleasy up to 50 orders/mo, In Cart Upsell with a single offer and a watermark), so you can build and test at zero cash cost before you pay. Second, some "free" or bonus tiers pay you per order by placing other brands' ads on your thank-you page, which is the opposite of a cost but rents out your own customer's post-purchase attention. We cover both routes honestly in the best free Shopify upsell app guide, because "free" in this category almost always has a footnote.
The three things that actually decide cheapest
Frequently asked questions
What is the cheapest Shopify upsell app? By entry price, ReConvert at $4.99/mo, as of July 2026. Zipify OCU (around $8, verify the tier), Selleasy ($9), Ultimate Special Offers ($9), In Cart Upsell ($9.99) and Bold or CartHook ($10) are the next-cheapest paid options.
Is the cheapest app really the cheapest to run? Not always. ReConvert and Zipify scale their pricing with your upsell revenue, and Bold, CartHook and Ultimate Special Offers take a percentage or usage fee on top, so the bill grows as the app earns. A flat-price app such as Also Bought ($19.99/mo) can cost less overall at higher upsell volume.
Is there a truly free upsell app? Many run free on development stores or offer order-capped free tiers, and some pay you per order by showing other brands' ads on your thank-you page. See our best free Shopify upsell app guide for the honest version.
Which cheap app converts best? ReConvert sits in the post-purchase one-click placement, which converts well for a structural reason: the payment is already authorized. For more on that placement see best post-purchase upsell app, and for the full placement-ranked field see the best Shopify upsell apps hub.
Bottom line
The cheapest Shopify upsell app by entry price is ReConvert at $4.99/mo, and for a store adding its first upsell that is the sensible, low-risk start. But treat the sticker as the floor, not the cost. ReConvert and Zipify scale their pricing with your upsell revenue, Bold and CartHook and Ultimate Special Offers take a percentage or usage cut, and those models mean your bill rises exactly when the app is working. If you already run real upsell volume, price out a flat-fee app like Also Bought or an order-volume-tiered app like Selleasy against the revenue-share options, because the cheapest app at zero revenue is rarely the cheapest at scale. Rank on the model, estimate your own crossover, and never compare on the entry number alone. For the full placement-ranked picture, start with our best Shopify upsell apps hub.
