Both apps upsell for free — but "free" ends at a different line for each. One counts total store orders every month; the other has no order line at all. The trade-off underneath that difference is the whole comparison.
Selleasy (Logbase) is free up to 50 total store orders a month, then $9/mo, and its established frequently-bought-together engine spans product, cart, and post-purchase with broad international support and 2,525 reviews at 4.9 stars. OrderMAX is free with every feature and no order cap or paid tier at all, but has a single App Store review against Selleasy's thousands — a track-record gap worth weighing before you install either one.
Six facts, pulled straight from each app's own Shopify App Store listing, before any of the nuance below.
Every number below is taken directly from the vendor's own Shopify App Store listing — Selleasy's on 26 August 2026, OrderMAX's is a standing plan with no expiry date to cite.
| Plan | Price | What caps it | Standout feature |
|---|---|---|---|
| OrderMAX | $0, no paid tier | No stated cap | Every feature included free |
| Selleasy free | $0 | 50 total store orders/mo | Frequently-bought-together across product, cart & post-purchase |
| Selleasy paid | $9/mo and up | Above 50 orders/mo | Same engine, broad international support |
Selleasy figures verified from its own listing at apps.shopify.com/upsell-cross-sell-kit-1 on 26 August 2026. OrderMAX figures from apps.shopify.com/ordermax-1.
Selleasy's free cap isn't upsell-attributed orders — it's every order the store processes, whether or not an upsell touched it. A store doing 60 orders a month from organic growth, with zero upsell activity, can still cross the 50-order line and land on the $9/mo tier. That's a meaningfully different trigger than a cap tied to upsell performance, and it's worth checking your own monthly order count against before assuming "free" applies to you.
Selleasy's edge is a frequently-bought-together engine that runs the same logic consistently across the product page, the cart, and the post-purchase screen — one connected recommendation flow, not three separate features bolted together. It also carries broad international support built up over years on the App Store. OrderMAX doesn't match that recommendation depth today; its case is a flat feature set with nothing gated behind a fee, not a smarter matching algorithm.
Selleasy's 50-order limit resets every month — a slow month puts a store back under the cap for free, unlike a lifetime-order limit that, once spent, never comes back. OrderMAX simply has no order line to reset against, which removes the monthly check-in entirely but comes from having no paid tier funding anything beyond what's already built.
Selleasy's real downside: the free plan is a moving target, not a fixed allowance. Because the cap counts total store orders and renews monthly, a growing store can get pushed onto the $9/mo tier for reasons that have nothing to do with upsell performance — success itself, not app usage, is what ends the free ride. At $9/mo that's a minor cost, but it's a cap you have to keep watching rather than one you can forget about.
OrderMAX's real downside: a single App Store review, against a competitor with thousands, and a recommendation engine that doesn't yet match Selleasy's frequently-bought-together depth across product, cart, and post-purchase. No paid tier also means no fee revenue funding the kind of years-long feature build-out that produced Selleasy's broader matching and international support. Free-with-no-cap is a real offer, but it's a newer one with less public evidence behind it.
Neither trade-off is hidden or disqualifying — they're just different bets. Selleasy bets on proven depth with a cap to manage; OrderMAX bets on an uncapped free plan with less of a track record yet.
OrderMAX fits a store that wants a full upsell feature set at $0, with no order count to track and no tier to eventually upgrade into. It's a reasonable pick for a store that has outgrown Selleasy's 50-order free cap and doesn't want to add a monthly line item, or one that simply wants to start with every feature unlocked from day one.
It is not the pick for a store that specifically needs Selleasy's frequently-bought-together matching across product, cart, and post-purchase, or that weighs 2,525 reviews at 4.9 stars as a meaningful signal of reliability at scale — OrderMAX currently has one App Store review, and that gap is real. The straightforward move for a cautious store is to install OrderMAX free, alongside or instead of Selleasy's free tier, and judge the recommendation quality on your own catalogue rather than on either app's marketing.
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 says anything about OrderMAX or Selleasy specifically, and no independent study has run the two apps head-to-head on matched Shopify stores. The category evidence supports "upsells generally work" — it does not tell you whether Selleasy's deeper matching or OrderMAX's uncapped free plan captures more of that lift on your catalogue. That's a question only your own funnel data can answer.
It depends on order volume and recommendation depth. OrderMAX fits stores that want every feature free with no order cap to plan around. Selleasy fits stores under roughly 50 orders a month that want frequently-bought-together bundles across product, cart, and post-purchase, and don't mind paying once they grow past that.
As of 26 August 2026, Selleasy's own Shopify App Store listing states its free plan allows "up to 50 orders/mo," counting the store's total order count, not just upsell-attributed orders. The cap renews every month rather than expiring permanently, and the first paid tier starts at $9/mo above 50 orders.
No. OrderMAX has a single free plan with every feature included and no stated order cap. There is no paid tier to graduate into, which also means there is no higher tier funding deeper R&D the way a paid competitor's fee revenue does — a real trade-off, not a hidden catch.
Selleasy has been on the Shopify App Store far longer and has accumulated 2,525 reviews at a 4.9 rating. OrderMAX currently has a single App Store review. That gap is real and worth weighing — a longer track record is evidence of its own kind that a fact sheet can't replace.
Selleasy's frequently-bought-together recommendations run across the product page, cart, and post-purchase in one connected flow, and it has broad international support built out over years of iteration. OrderMAX doesn't compete with that depth of matching yet.
The 50-orders-a-month cap renews monthly rather than expiring permanently, so a slow month resets you back under the limit. But it counts total store orders, not just orders touched by an upsell, so a store growing for reasons unrelated to upselling can still get pushed into the $9/mo tier.
Yes, for stores under the cap — Selleasy's free tier works on a live store, not just a development store, up to 50 total orders a month. It stops being usable at $0 the moment a store's total order count crosses that line, which is a monthly recurring limit rather than a one-time allowance.
It means OrderMAX has far less public review history than an established app like Selleasy, and that's a fair thing to weigh before installing. It does not by itself say anything about whether the app works — the feature set and the no-cap free plan are verifiable independent of the review count.
Yes. Shopify apps install and uninstall independently, so a store can run Selleasy up to its free cap, move to OrderMAX for unlimited free volume, or run a trial period on both to compare recommendation quality before settling on one.
OrderMAX has no cap and no paid tier to graduate into — every feature, at $0, for as long as your store keeps growing.
