Best free upsell apps for Shopify, compared

As of 26 August 2026, seven widely used upsell apps advertise a free tier: OrderMAX, Selleasy, Essential Upsell & Cross Sell, BOGOS, iCart, Upsell.com (ReConvert) and Honeycomb. Six of the seven cap the free tier. OrderMAX is the only one of the seven with no stated cap, and Upsell.com’s free plan is restricted to development stores, so it is not usable on a live storefront.

Four different units, which is why roundups disagree. Selleasy counts your store’s total monthly orders, not upsell orders, and charges above 50 per month. iCart and BOGOS count lifetime orders — 100 and 30 respectively — after which the free tier is spent permanently. Essential Upsell counts attributed revenue and stops at $100 generated. Honeycomb counts funnel views and allows 100 per month. Comparing the headline word “free” across these is meaningless; comparing the unit is not.

Yes, but the count is your store’s total order volume, not the orders the app influenced. Selleasy’s own listing states: “Up to 50 orders/mo. Your store’s total order count will be considered.” A store doing 60 orders a month pays $9 even if the app touched none of them. This is the single most misread free plan in the category.

For depth of promotional mechanics, BOGOS is the most established — twelve years in the category, 95,000+ brands, and support for POS and headless storefronts. Its free tier is the tightest in this comparison at 30 lifetime orders, so it functions as an extended trial rather than an ongoing free plan. For gift-with-purchase and BOGO on an uncapped free tier, OrderMAX includes both, with the trade-off that it is a much newer app.

For validating whether upsells lift your average order value, yes — every app in this comparison can run a real offer on a real storefront. The question is what happens after validation. On a capped plan the offers stop or the bill starts precisely when the app begins working, which is why the cap unit matters more than the feature list when you choose.

Because omitting it would be a different kind of dishonesty. This comparison is published by OrderMAX and that is a real bias. The mitigations: every competitor’s pricing was read from their own Shopify App Store listing on 26 August 2026 and quoted verbatim, each entry names what that app does better than OrderMAX, and OrderMAX’s own weakness — a single App Store review against competitors with thousands — is stated in its entry rather than buried.

One, rated 5.0, as of 26 August 2026. Every other app in this comparison has between 146 and 4,092 reviews. A merchant choosing an upsell app on track record rather than on pricing should weigh that heavily, and this comparison does not argue otherwise.

A free trial gives the full product for a fixed window — commonly 7 to 30 days in this category — and then bills the store. A free plan is permanently available but deliberately limited by a cap. Several apps run both: Selleasy pairs a free-to-install tier with 30-day trials on its paid tiers, and Upsell.com pairs a development-store-only free plan with 14-day trials. Shopify requires merchant approval through its own billing screen before any charge begins, so no app can start billing silently.

The mechanism is well evidenced; the magnitude is not guaranteed. McKinsey’s widely cited analysis attributes roughly 35% of Amazon purchases to recommendation-driven cross-sells, and AfterSell’s aggregate merchant data reports an average 9.74% AOV lift from post-purchase offers. Neither figure predicts a specific store’s result, which depends on catalogue, margin and offer relevance. That uncertainty is the strongest argument for starting on a free tier rather than a paid one.
