Rebuy Alternatives That Lift Order Value Without the Fees
Rebuy is a strong upsell engine, and its bill grows with every order you ship. Here are the Rebuy alternatives worth a look, with prices checked on the Shopify App Store today, plus the one number no upsell app can move.
Your upsell app gets paid every time you ship.
That's the deal with Rebuy, and most founders only notice it when the store grows. More orders, bigger bill. Fair enough, if the app earns it. But I've sat on audit calls where the founder was paying for a smart cart, a post-purchase package and a flows package, and couldn't tell me what any of the three earned last month.
Here's the short answer on rebuy alternatives. If you use one Rebuy job, swap it for a specialist: UpCart for the cart drawer, ReConvert or AfterSell for post-purchase offers, Frequently Bought Together CBB for bundles on the product page. If you run three or more Rebuy packages and the numbers prove they pay, stay. Rebuy is a good product with a 4.7 rating.
And then there's the part none of the comparison posts say out loud. Every app on this list works on buyers who already said yes. None of them touch the visitors who leave your product page without adding to cart. We'll put numbers on that.
What do Rebuy's pricing tiers actually cost in 2026?
Rebuy doesn't sell one plan anymore. On its pricing page you build your own plan from four packages, and each one has a base price that covers up to 500 orders a month:
| Rebuy package | What's inside | Base price (up to 500 orders/mo) |
|---|---|---|
| Cart & Merchandising | Smart Cart, merchandising widgets, dynamic bundles, bundle builder | $45/mo |
| Checkout & Post-Purchase | Checkout extensions, post-purchase offers (Shopify Plus) | $25/mo |
| Search & Collections | Smart Search, Smart Collections | $35/mo |
| Flows & A/B Testing | Smart Flows, A/B testing, reorder landing pages | $35/mo |
| Premium Support | Add-on | $499/mo |
| Platform One | Every package plus a dedicated success manager | Quoted by sales |
Take all four packages at the base and you're at $140 a month. That's the number on our cover. Past 500 orders, every package is priced on orders per month, so the bill climbs as you grow. Annual billing knocks off 10%, the trial runs 14 days, and Rebuy says it bills on a prorated 30-day cycle based on the previous 30 days of orders.
Rebuy also advertises an ROI guarantee: positive ROI, measured as what you spend on the platform against the extra revenue Rebuy drives. Read that sentence twice. It's measured on Rebuy's attribution, on buyers who were already checking out.
The Shopify App Store listing showed 4.7 stars from 854 reviews when I checked it today, with the Built for Shopify badge. The low-star reviews cluster around support and billing surprises, so read your first invoice closely.
An upsell app is paid on the buyers you already won. The buyers you lost on the product page never show up on its invoice, or its dashboard.

I opened every listing below on the Shopify App Store today, September 30, 2026. Every third-party app on it carries the Built for Shopify badge. Prices move, so check again before you install.
| App | Replaces which Rebuy job | Price on the listing | Rating (reviews) |
|---|---|---|---|
| Rebuy (the baseline) | Cart, bundles, checkout, post-purchase, search, flows | $25 to $45 per package/mo at 500 orders, rises with order count | 4.7 (854) |
| UpCart | Cart drawer, in-cart upsells, free shipping bar | $29.99/mo (200 orders) to $54.99/mo (1,000 orders) | 4.7 (952) |
| ReConvert | Post-purchase and thank-you page upsells | Free to 50 orders, Growth $9.99/mo up to 2,000 orders | 4.8 (3,093) |
| AfterSell | Post-purchase funnels, AI cart, recommendations | $34.99 to $79.99/mo, 30-day trial | 4.9 (1,073) |
| Frequently Bought Together CBB | Product page bundles and recommendations | Free plan, paid $14.99 to $39.99/mo | 4.9 (1,201) |
| Shopify Search & Discovery | Basic related and complementary products | Free | 2.7 (507) |
That's the shopify upsell app comparison in one table. Now the part that matters: which one fits the job you actually use.
UpCart if the Smart Cart is your main Rebuy job
UpCart does the slide-out cart: AI-powered in-cart upsells, a rewards bar for free shipping, add-ons and trust badges. Starter is $29.99 a month up to 200 orders, Professional $34.99 up to 500, Advanced $54.99 up to 1,000. Same order-based model as Rebuy, cheaper floor.
ReConvert or AfterSell if post-purchase is the job
ReConvert has the most reviews on this list, 3,093 at 4.8 stars. It's free up to 50 orders or $50 in upsell revenue, then $9.99 a month on Growth up to 2,000 orders.
AfterSell starts at $34.99 for post-purchase, $59.99 for the pre-purchase AI cart, and $79.99 for both plus a recommendation engine, with a 30-day trial. Its listing is clear that checkout widgets need Shopify Plus, while post-purchase upsells work on every plan.
Frequently Bought Together CBB for bundles on the product page
Frequently Bought Together CBB puts AI or hand-picked bundles right on the product page with one-click add to cart. Free for up to 3 manual bundles, then $14.99 a month up to 50 orders, $19.99 up to 500, $39.99 above that.
Shopify Search & Discovery if you want free and basic
Shopify's own Search & Discovery app is free. Its help page says you can hand-pick up to 10 complementary and 10 related products per product, but they only show if your theme has the right sections. The 2.7 rating tells you what merchants think of the search side.
Pick the app for the one job you use. Paying for four engines to run one cart drawer is how upsell bills get fat.
Why can't any upsell app fix the buyers who leave?
Here's the thing. Every app above, Rebuy included, wakes up after the add-to-cart click. The cart drawer, the thank-you page, the one-click offer after checkout. They all work on the same small group: the buyers your product page already convinced.
So what happens to everyone else?
Run the math on a store like this, a hypothetical skincare brand selling a $64 vitamin C serum. 10,000 visitors a month. Conversion rate 2.5%, average order value $64. That means revenue per visitor is $1.60. On 10,000 visitors, that's $16,000. That's 250 orders, under Rebuy's 500-order base.
Now add a good cart upsell. Say it lifts average order value to $70 and the conversion rate holds at 2.5%. Revenue per visitor is $1.75. On the same 10,000 visitors, that's $17,500. A $1,500 lift. Probably worth the app fee.
Now fix the page instead. The product page gets rebuilt to answer the buyer's real question ("Will this actually fade my dark spots, or is it another $64 bottle in the drawer?") and a 2-bottle bundle becomes the default offer. Conversion rate 3.4%, average order value $78. Revenue per visitor is $2.65. On the same 10,000 visitors, that's $26,520.
Conversion rate x average order value x visitors. Hypothetical example.
$1,500 from the upsell. $10,520 from the page. The upsell is a tip jar at the register. The page is the salesperson on the floor.
Try your own numbers here. The defaults match the example.
I'm not anti-upsell. Actually, scratch that, I'm anti upsell-first. Bolt the tip jar on after the salesperson can close. We walk through what happens when cart offers go wrong in do cart upsells hurt Shopify conversion rate, and how to tune the ones you keep in our guide to Shopify upsells that add $21 per order.
For numbers that aren't hypothetical: a bedding brand with 30+ products rebuilt its top 3 hero pages. Conversion rate went from 1.0% to 3.5%, average order value from $125 to $231. Revenue per visitor moved from $1.25 to $8.10. On 10,000 visitors, that's $12,500 versus $81,000. See the full case study numbers. Real client numbers, not typical results, and not a promise of what your store will do. Notice the average order value nearly doubled, and no upsell app did it. The page and the offer did.
How is AI changing the rebuy engine alternatives question?
Every app on this list now says "AI" on its listing. Rebuy has AI recommendations and search. UpCart has AI-powered in-cart upsells. AfterSell has Smart Funnel AI. Frequently Bought Together CBB has AI bundle picks.
All of that AI answers one question: which product goes next to this one? Useful, but it only works on buyers already in the cart.
The bigger shift is AI pointed at the page itself. Writing the headline, the objection answers, the bundle offer and the order of the argument, so more visitors reach the cart at all. That's where we aim AI when we build pages with RevenueFlows AI, and it's why the order value lifts in our case studies came from the page and the offer, not a widget. We made the same call in our Zipify alternatives breakdown and our Vitals app alternatives teardown: more tools on a page that can't sell is decoration.
How do you switch off Rebuy without losing revenue?
- Pull 90 days of Rebuy-attributed revenue per package before you cancel anything.
- Duplicate your live theme and do every change on the copy.
- Install one replacement at a time, starting with the package that earns the most.
- Run the new app for 30 days and compare its attributed revenue to the Rebuy number.
- Check revenue per visitor before and after, not just average order value.

Frequently asked questions
What is the best alternative to Rebuy for Shopify?
It depends on which Rebuy job you use. For a cart drawer with upsells, UpCart starts at $29.99 a month. For post-purchase one-click offers, ReConvert has a free plan and a $9.99 Growth plan, and AfterSell starts at $34.99. For frequently bought together bundles on the product page, Frequently Bought Together CBB has a free plan.
How much does Rebuy cost in 2026?
Rebuy sells four packages that each start at a base price covering up to 500 orders a month: Cart and Merchandising at $45, Checkout and Post-Purchase at $25 (Shopify Plus), Search and Collections at $35, and Flows and A/B Testing at $35. Prices rise with your monthly order count, and the full Platform One suite is quoted by sales.
Is Rebuy worth it for a small Shopify store?
Under 500 orders a month, Rebuy's base packages are affordable and the 14-day trial is long enough to test one. The cost question gets real as orders grow, because every package is priced on orders per month. Measure the extra revenue each package drives against its bill before you add a second one.
Does Rebuy work without Shopify Plus?
Yes. The Smart Cart, merchandising widgets, bundles, search and flows work on standard Shopify plans. Rebuy's Checkout and Post-Purchase package is listed for Shopify Plus, and other apps such as AfterSell note that checkout widgets need Plus while post-purchase upsells work on all plans.
Can an upsell app raise my conversion rate?
Rarely by much. An upsell app works on buyers who already decided to buy, so it lifts average order value. The buyers who leave the product page before adding to cart never see the offer. That gap is a page problem, and it usually costs more than the upsell earns.
