Update, 22 October 2026: Selleasy and Upsell.com — ReConvert are no longer listed on the Shopify App Store — the listing now returns “this app is not currently available”. We have left the assessment below for reference and removed the install links, because they led to a dead page. Both were ranked below. We have removed their install links and our current pick is Essential Upsell & Cross Sell, 5.0 from 2,432 reviews. See the what to use instead of the removed upsell apps →
Update, 2 September 2026: Rapi left our partner programme, so its link below now earns us nothing. We have kept it in the comparison because the pricing analysis still stands — the app is listed as Rapid Bundles & Upsell and holds 5.0 from 1,370 reviews. Every other app on this page remains a partner link.
Short answer
Upsell apps look interchangeable and price completely differently. The
feature lists converge; the meter does not. One charges on your total store orders, another on
the revenue it generates for you, another on bundle sales only, and one charges nothing at all. Pick the wrong
meter and a $9.99 app quietly becomes a $60 app.
If you want the short version: Essential Upsell & Cross Sell for product-page and post-purchase offers,
G: Volume Discounts if you only need quantity breaks and would rather pay nothing, and
Post Purchase Upsell Hero if you are large enough that a percentage that falls to zero
beats any flat fee.
Best all-rounder
Essential Upsell & Cross Sell — 5.0 from 2,432 reviews, Built for Shopify. Free until it generates $100 of extra revenue, then $9.99. Product page and post-purchase on every tier.
Best free option
G: Volume Discounts — 5.0 from 110 reviews and genuinely free, with no paid tier
anywhere on the listing.
Best at scale
Upsell Hero — 2.5% of upsell revenue to $20k a month, then 0%. The only app
here that gets cheaper as you grow.
What each app actually charges you for
This is the table we wanted when we started and could not find anywhere. Same fifteen apps, sorted by review
count, with the thing that determines your bill in the second column.
| App | Meter — what you pay on | Tiers | Where it upsells |
|---|---|---|---|
 Essential Upsell5.0 from 2,215 reviews |
Upsell revenue | Free to $100 → $9.99 ($500) → $19.99 ($1,000) → $39.99 unlimited | Product page, cart from $19.99 |
 Rapi Bundles5.0 from 1,370 reviews |
App-generated revenue | Free to $100/mo → $15 ($1,000) → $29 ($10,000) → $59 unlimited | Bundles & post-purchase |
 Easy Bundles4.9 from 1,119 reviews |
Bundle sales revenue | Free to $500/mo → $29 ($3,000) → $49 ($5,000) → $99 ($10,000) | Bundle builder |
 Kite Discount4.9 from 1,039 reviews |
Discount orders | First 50 free → $29 unlimited → $49 → $99 | Free gift & BOGO |
 MBC Bundles4.9 from 350 reviews |
Total store orders | Free to 10 orders → $15.99 (250) → $59.99 (1,000) → $159.99 (2,500) | Mix & match bundles |
 Koala Free Gift BOGO4.9 from 348 reviews |
Flat, by Shopify plan | $9.99 → $29.99 → $49.99 → $99.99 (Plus) | Free gift & BOGO |
 Assortion4.9 from 313 reviews |
Free plan available | Free tier, then paid | Cross-sell & product options |
 UpsellPlus5.0 from 123 reviews |
Flat | From $49/mo — Shopify Plus required | Checkout page |
| G: Volume Discounts 5.0 from 110 reviews |
Nothing | Free. No paid tiers at all. | Volume & quantity breaks |
 Cartly Slide Cart4.9 from 82 reviews |
Free plan available | Free tier, then paid | Cart drawer |
 Wiz Checkout Upsell4.9 from 51 reviews |
Flat | $49 (post-purchase only) → $99 (actual checkout) → $199 | Checkout & post-purchase |
 Elite Cart Drawer5.0 from 46 reviews |
Orders above tier cap | $29.99 incl. 200 orders → $79.99 incl. 500, then scales | Cart drawer |
| Post Purchase Upsell Hero 5.0 from 15 reviews |
% of upsell revenue | $0/mo + 2.5% to $20k, then 0% | Post-purchase |
Read the second column before the third. Two apps at “$9.99” are not comparable if one counts
your whole order book and the other counts only the extra revenue it made you.
Five pricing traps worth knowing before you install
1. Some meters count your total orders, not upsell orders. MBC and several others raise charges with monthly order volume regardless of how many upsells you actually sell. So a store doing 500 orders a month pays the 500-order
rate even if only twenty of those orders ever saw an upsell. On a high-volume, low-upsell store this is the most
expensive app on the page rather than the $4.99 one.
2. Kite’s cheap tiers exclude Advanced and Plus merchants. The Free and $29 Starter
plans are marked “Not for Shopify Advanced and Plus plans”. If you are on either, your real entry
price is the $49 Growth tier — and free gifts at checkout need the $99 Pro plan
on top of already being on Plus.
3. Wiz “Checkout Upsell” does not do checkout upsells on its entry plan. The $49
Essential tier is post-purchase, thank-you page and order-status only. The actual checkout-page upselling the app
is named after starts at $99, and needs Checkout Extensibility.
4. Elite Cart’s $29.99 holds only under 200 orders. The tier includes 200
orders a month and then scales with volume — the listing’s own example adds $10 at 500 orders.
It is a floor price, not a price.
5. UpsellPlus needs Shopify Plus, full stop. Checkout upsells depend on checkout
extensibility, which is a Plus capability. At $49 a month minimum it is excellent and completely irrelevant if
you are not on Plus. Do not lose an afternoon to it first.
Where the upsell actually appears
The second decision, and the one that determines whether an app can help you at all. Four surfaces, and most
apps only cover one or two.
Product page
Offers shown before the customer commits. Highest reach, lowest disruption. Essential Upsell, Assortion.
Cart & drawer
Caught on the way out. Converts well, but disappears entirely if you use a skip-the-cart flow.
Cartly, Elite Cart, Essential Upsell (from $19.99).
Checkout page
Shopify Plus only. The highest-intent surface and the one most stores cannot use.
UpsellPlus, Wiz (from $99).
Post-purchase
After payment, so it cannot cost you the original order — the safest place to test.
See Essential Upsell & Cross Sell →, Upsell Hero, Rapi Bundles.
If you are only going to install one thing
Start post-purchase. An offer shown after payment cannot
reduce your conversion rate, cannot slow your product page, and cannot annoy someone into abandoning a cart. It
is the only upsell surface with no downside risk to the order you already won — which makes it the right
place to find out whether your customers respond to upsells at all before you touch the pages that matter.
The two outliers
The one that is actually free
G: Volume Discounts & Bundles holds 5.0 from 110 reviews and has no paid tier on its
listing at all. If what you need is quantity breaks — buy 3 save 10% — rather than recommendation
engines and funnels, this does the job for nothing. It is a narrower app than the others here, and that is
exactly why it can be free.

The one that gets cheaper as you grow
Post Purchase Upsell Hero charges $0 a month plus 2.5% of the upsell revenue it generates
— but only on the first $20,000 a month. Above that the rate is 0%. Every other
usage-priced app on this page charges you more as you scale; this one stops charging. The practical effect is a
ceiling of roughly $500 a month no matter how large you get.
The honest caveat is the review base: 15 reviews. The pricing model is the most
merchant-friendly here and the track record is the thinnest. That is a real trade, not a hidden one.

Essential Upsell in detail, since it is our pick
Essential Upsell is not the flashiest app here and that is rather the point. It covers product-page, cart and post-purchase offers, it carries the Built for Shopify badge, and its meter is the one that cannot punish you for growing: the extra revenue the app itself generates, with the first $100 a month free.
Pros ✓
- 5.0 from 2,432 reviews, 97% of them five-star — the deepest review base on this page
- Built for Shopify badge, which Shopify grants against its own performance and integration standards
- Metered on the upsell revenue it generates, so it only costs you money once it has made you some
- Free until the app has generated $100 of additional revenue, with product-page and post-purchase offers included
- Product page, cart and post-purchase offers from one app
- 14-day trial on every paid tier
Cons ✕
- Cart-page offers need the $19.99 tier — the free and $9.99 plans cover product page and post-purchase only
- The revenue meter means a good month can push you into the next tier mid-month
- No checkout-page upsells — that needs Plus and a different app
- Attribution of “additional revenue generated” is the app’s own figure, so sanity-check it against your own reporting
- We have not run it on a live store; this assessment is from the listing, pricing and review distribution

The mistake that costs the most
Almost every store evaluates these apps on the monthly fee and the feature list, then discovers the bill three
months later. The fee is the least informative number on the listing.
Work it out with your own figures before you install. Take your monthly order count, your realistic upsell
acceptance rate — 5–10% is a sane starting assumption, not the 30% in the marketing — and your
average upsell value. Then run that through each meter:
- Total-orders meters (MBC and others) charge on your whole order book. Cheapest when
upsells are a big share of your orders; worst when you are busy but rarely upsell. - Upsell-revenue meters (Essential Upsell, Rapi, Upsell Hero) only charge when the app earns.
Safer on a high-volume store, and they scale with your success rather than your size. - Flat fees (Koala, UpsellPlus, Wiz) are predictable and become the cheapest option once you are
large — and the most expensive while you are small.
A store doing 800 orders a month with a 6% upsell rate is making roughly 48 upsells. On a total-orders meter you
pay the 800-order price for 48 upsells. On an upsell-revenue meter you pay for 48. That difference is usually
larger than any feature gap on this page.
What we would install, by store
| If you are… | Install | Why |
|---|---|---|
| Just starting with upsells | Essential Upsell | Free until the app has earned you $100, so it costs nothing until it works. |
| Doing real volume, few upsells | Essential Upsell |
Meters on upsell revenue rather than total orders, so a big order book does not inflate the bill. |
| Above $20k/mo in upsells | Upsell Hero | The 0% band above $20k caps you near $500 — cheaper than any percentage that keeps climbing. |
| Only wanting quantity breaks | G: Volume Discounts | Free, 5.0 from 110 reviews, and does precisely that one job. |
| On Shopify Plus | UpsellPlus |
Checkout-page upselling is the highest-intent surface and Plus is the only way to reach it. |
| Running BOGO and free gifts | Koala Kite |
Koala is flat-priced and predictable; Kite is cheaper at low volume but excludes Advanced/Plus from its cheap tiers. |
| Selling bundles, not add-ons | Rapi Bundles |
Free to $100/mo of app-generated revenue with post-purchase upsells included at no cost. |
How to test one without wrecking your conversion rate
- Record your baseline first — conversion rate and average order value, for at
least two weeks. An upsell app that lifts AOV while cutting conversion can lose you money while every dashboard
says it is working. - Start post-purchase. No risk to the order you already have.
- One offer at a time. Stacked offers make attribution impossible and irritate customers.
- Check the meter after 30 days, not the monthly fee. Compare the actual charge against what
the app claims it generated. - Test on mobile. Cart drawers and pop-up offers behave differently on small screens, which is
where most of your traffic is. - Give it a full month before judging. Upsell acceptance rates are noisy at low order counts.
Bottom line
For most stores the answer is Essential Upsell & Cross Sell: free until the app has generated $100 of extra revenue, $9.99 to $500 and $19.99 to $1,000, with 5.0 across 2,432 reviews and the Built for Shopify badge. It covers the product page and post-purchase on every tier, and the cart from $19.99.

FAQs
What is the best Shopify upsell app in 2026?
For most non-Plus stores, Essential Upsell & Cross Sell — 5.0 from 2,432 reviews, Built for Shopify, free until it has generated $100 of extra revenue and $9.99 after that, covering the product page and post-purchase on every tier. Essential Upsell includes post-purchase offers on every tier, including the free one. If you only need quantity breaks, G: Volume
Discounts does that free.
Are there free Shopify upsell apps?
Yes, and they differ. G: Volume Discounts is free outright with no paid tier. Essential Upsell, Rapi Bundles, MBC and Kite all have free tiers capped by a meter — orders, upsell revenue or
bundle sales — so they are free until you succeed. Read which meter applies before assuming you will stay
free.
Do I need Shopify Plus for checkout upsells?
For upsells on the checkout page itself, yes. That surface depends on checkout extensibility, which is a Plus
capability, so UpsellPlus and Wiz’s $99 tier both require it. Post-purchase and thank-you-page upsells work
on any plan, which is why they are the usual starting point.
Will an upsell app hurt my conversion rate?
It can, on the product page and in the cart, where an offer adds friction before payment. Post-purchase offers
cannot — the order is already complete. Whichever you choose, track conversion rate and average order value
together, because a lift in one can hide a fall in the other.
Why do two apps at the same monthly price cost different amounts?
Because they meter different things. MBC counts your total store orders, Essential Upsell counts only the extra revenue it generated, Easy Bundles counts bundle sales, and Koala charges a flat fee by Shopify plan.
On a busy store with few upsells, the total-orders meter is far more expensive than the headline suggests.
Which upsell app is cheapest at high volume?
Post Purchase Upsell Hero, because its rate falls rather than rises — 2.5% on the first $20,000 of
upsell revenue a month and 0% above that, which caps the cost near $500 regardless of scale. The trade-off is a
thin track record at 15 reviews.
Should I run more than one upsell app?
Generally no. Two apps competing for the same surface produce duplicate offers, conflicting discounts and
attribution you cannot read. The exception is pairing surfaces deliberately — for example a product-page
app plus a post-purchase app — and even then, launch them a few weeks apart so you can tell which did what.
