One free plan is capped only by your store's own order count and renews forever. The other's free plan can't run on a live store at all — it exists purely for development testing. That single gap, not the feature lists, is what actually separates these two apps.
Selleasy's free plan is usable on a live store — up to 50 orders a month, renewing monthly, forever. Upsell.com's free plan only works on development stores, so on a real live store its cheapest working plan is $4.99/mo. Selleasy is the better $0 option; Upsell.com is cheaper once you're paying anyway.
Facts pulled directly from each vendor's own Shopify App Store listing, as of 26 August 2026.
Both listings describe their free plans in their own words. Selleasy: "Up to 50 orders/mo. Your store's total order count will be considered." Upsell.com: "Available for development stores." Those two sentences are the entire difference between a free plan you can run today and one you can only test in a sandbox.
| App | Plan | Price | Cap unit | Standout feature |
|---|---|---|---|---|
| Selleasy | Free | $0 | 50 orders/mo, total store orders (renews monthly, never permanently expires) | Frequently-bought-together recommendations across product, cart & post-purchase |
| Selleasy | Paid (from) | $9/mo | Unlocks orders beyond 50/mo | Broad international market support |
| Upsell.com | Free | $0 | Development stores only — not usable on a live storefront | Full-stack post-purchase & thank-you-page funnels |
| Upsell.com | Paid (from) | $4.99/mo | From 50 orders | A/B testing & advanced analytics identical across every tier |
Selleasy: apps.shopify.com/upsell-cross-sell-kit-1 · Upsell.com: apps.shopify.com/reconvert-upsell-cross-sell — both read from the vendor's own listing on 26 August 2026.
Upsell.com's $4.99/mo entry point is the cheapest paid tier in this comparison, and it comes with A/B testing and advanced analytics that its listing describes as identical across every tier — including the free one no live store can actually use. Selleasy's listing states only the $9/mo starting price above 50 orders/mo and doesn't break out further named tiers.
The pricing tables tell you what each plan costs. They don't tell you what the apps are actually built to do — and on that, Selleasy and Upsell.com aren't really solving the same problem.
Selleasy's free plan runs on your real storefront, taking real orders, capped only by your store's own monthly order count. Upsell.com's free plan runs on a Shopify development store — a sandbox environment used for building and testing themes or apps before launch, not a channel that ever sees a live customer. That means Upsell.com effectively has no free plan for any operating business; its real starting price is $4.99/mo.
Selleasy's edge, per its own listing, is frequently-bought-together recommendations spread across the product page, the cart, and post-purchase — three placements pulling from the same matching logic. Upsell.com's edge is narrower and deeper: full-stack post-purchase and thank-you-page funnels, with A/B testing and advanced analytics built in from its very first paid tier. A store optimizing what happens right after checkout gets more purpose-built tooling from Upsell.com; a store wanting broad cross-sell coverage across the whole shopping journey gets more from Selleasy.
Upsell.com's listing describes A/B testing and advanced analytics as identical across every tier — the gate is volume (orders), not functionality. Selleasy's listing doesn't make the same feature-parity claim across its tiers; its own emphasis is on broad international support once you're past the free cap. That's a meaningfully different pricing philosophy: pay for more orders on Upsell.com, or pay for more orders and possibly more capability on Selleasy.
Neither app's free plan is free of a real cost. Both vendors have simply chosen to charge it in a different currency than dollars.
Selleasy's free plan counts your store's total order count, not orders the upsell app itself influenced. A store can lose its free plan from general sales growth that has nothing to do with Selleasy at all — the app could be doing almost nothing and you'd still cross 50 orders a month simply because the rest of the business is doing well. The cap renews every month, which is generous, but it's tied to a number the app doesn't control.
A development-store-only free plan isn't a capped allowance you can spend down over time — it's a plan that never applies to a real store in the first place. There's no free orders to burn through, no monthly reset to wait for, because the free tier was never usable for actual sales. For any merchant running a live storefront, Upsell.com's honest starting price is $4.99/mo from day one, not $0.
| Use case | Better fit |
|---|---|
| Want a genuinely free plan usable on a live store today | Selleasy — its free tier isn't restricted to development stores |
| Building post-purchase or thank-you-page offers with A/B testing baked in | Upsell.com — this is its core specialty from the entry paid tier up |
| Want the lowest possible paid entry price once you're paying anyway | Upsell.com — $4.99/mo is the cheapest first paid tier of the two |
| Want broad frequently-bought-together coverage across product, cart & post-purchase | Selleasy — its listing specifically claims this breadth |
This comparison is published by OrderMAX, so take this section as a vendor pitch, not neutral advice — the rest of the page above it is not. OrderMAX is a separate free Shopify upsell app with no order cap, no paid tier, and no development-store restriction on its free plan, which sidesteps both trade-offs described above. It doesn't match Upsell.com's A/B-tested post-purchase funnel depth or Selleasy's breadth of FBT placements; it's a simpler tool for a store that wants upsells running, live, with nothing to hit a limit on.
Tier 2 — named third party, self-reported. AfterSell's aggregate merchant data reports an average 9.74% AOV lift from post-purchase upsell offers specifically. This is vendor-reported aggregate data, not an independent audit — treat it as directional.
Tier 3 — industry benchmark. McKinsey's widely cited analysis attributes roughly 35% of Amazon purchases to recommendation-driven cross-sells. This describes one platform at extreme scale and personalization depth; it is evidence the mechanism works broadly, not a forecast for any specific Shopify store.
What this evidence does not say: neither figure was measured on Selleasy or Upsell.com specifically, and no independent study has run the two apps head-to-head on matched Shopify stores. The category evidence supports "cross-sell and post-purchase mechanics generally lift AOV" — it says nothing about which of these two apps lifts it more for your catalogue, or whether Upsell.com's A/B testing actually outperforms Selleasy's broader placement coverage on your specific traffic.
Neither wins outright. Selleasy's free plan works on a live store today, capped at 50 orders a month and renewing every month. Upsell.com's free plan only runs on development stores, so its cheapest live-store option is $4.99/mo — but that tier includes full post-purchase funnels and A/B testing Selleasy doesn't emphasize.
No. As of 26 August 2026, Upsell.com's own App Store listing states its free plan is "Available for development stores" only. A development store is a testing environment, not a real storefront taking customer orders — so for any live business, Upsell.com's real starting price is $4.99/mo, not $0.
Per Selleasy's own listing, verified 26 August 2026: "Up to 50 orders/mo. Your store's total order count will be considered." That's your entire store's order volume, not just orders the upsell influenced, and the allowance renews every month rather than expiring for good.
Selleasy's paid tier starts at $9/mo once a store passes 50 total orders in a month. Upsell.com's paid tier starts at $4.99/mo from 50 orders — the cheaper of the two entry prices, despite Upsell.com bundling deeper post-purchase funnel features from that tier up.
As of 26 August 2026, Selleasy (Upsell & Cross Sell) shows 4.9 stars across 2,525 reviews on the Shopify App Store. Upsell.com (formerly ReConvert) shows 4.8 stars across 2,803 reviews. Both are well-established, high-volume listings in the upsell and cross-sell category.
Full-stack post-purchase and thank-you-page funnels, plus A/B testing and advanced analytics that stay identical across every paid tier. Selleasy's strength runs the other way: frequently-bought-together recommendations across the product page, cart, and post-purchase, with broad international support — breadth over funnel-testing depth.
For staying on a working free plan, Selleasy — its 50-orders-a-month cap renews indefinitely at $0 and works on a live store from day one. Upsell.com's free tier never applies to a live store regardless of volume, so a growing store on Upsell.com pays from $4.99/mo the moment it goes live.
Upsell.com, based on its own listing's emphasis on full-stack post-purchase and thank-you-page funnels with built-in A/B testing and analytics from its paid tiers. Selleasy also supports post-purchase placements within its broader recommendation engine, but its documented strength is cross-sell breadth, not funnel-testing depth.
Yes — OrderMAX is a separate Shopify upsell app, also published by OrderMAX, the site hosting this comparison. It's free with no order cap, no paid tier, and no development-store restriction, though it doesn't match Selleasy's FBT breadth or Upsell.com's post-purchase funnel depth.
