Essential has the fairest-sounding free plan in the category: you pay nothing until the app has generated $100 of additional revenue. It is a genuinely good structure — and it is also the one that ends soonest for an app that works, because success is exactly what spends the allowance.
Essential rates 5.0 across 2,234 reviews, and its listing frames the free plan as "up to $100 additional revenue generated" — the vendor's stated principle being that it never bills for an app that has not helped. That is a better alignment than counting your total store orders. Two things still push merchants to look.
A working app spends the allowance fast. On a $50 average order value, $100 of attributed revenue is two upsold orders. The better the app performs, the sooner the free plan ends — which is logically fair and practically short. An order-capped monthly plan gives you a predictable window instead.
Attribution becomes the thing you are buying. When billing is tied to generated revenue, the attribution model matters as much as the feature set: what counts as app-influenced, over what window, and whether a shopper who would have bought anyway is included. That is worth reading closely on the listing, because it is the number your invoice is based on.
For reference, the first paid tier is $9.99/mo for up to $500/mo generated — still modest, and tied to output rather than to how busy your store is.
| App | Free plan | First paid tier | Listing rating | Standout |
|---|---|---|---|---|

| If you… | Look at |
|---|---|
| Want a predictable monthly window rather than a revenue allowance | Selleasy (50 orders/mo) or Wiser AI (0–50 orders/mo) |
| Want the largest one-time free allowance | iCart — 100 orders lifetime |
| Need gift with purchase, BOGO or bundle depth | BOGOS, or our free-gift feature pages |
| Want split testing on a free plan | Honeycomb — free within 100 funnel views/mo |
| Want the lowest paid entry price | Upsell.com at $4.99/mo, though its free plan is dev-stores only |
| Do not want any cap | NUO AI — disclosed vendor pitch, see below |
None of these is the right answer for every store, and the deciding factor is almost never the feature list — it is what ends the free plan and what the first paid tier costs when it does. A cap counted in views behaves nothing like a cap counted in orders, and a lifetime allowance behaves nothing like a monthly one.
We maintain direct comparisons between these apps, each built from the vendors' own listings rather than from feature-matrix marketing:
If you are deciding between two specific apps, those pages are more useful than this one — they go into the exact wording each vendor uses to describe its cap.
This page is published by NUO AI, so treat this section as a vendor pitch and the rest of the page as research. We build a free Shopify cart upsell, cross-sell and free-gift app with no order cap, no view cap, no revenue cap, and no paid tier to graduate into — which sidesteps the cap question entirely rather than answering it.
What we do not claim: we are a newer app with far fewer reviews than any vendor in the table above, and we do not match the promotional depth of a specialist that has spent a decade on gifting mechanics. What we do offer is every feature at $0 — auto-added free gifts, spend thresholds, quantity breaks, funnel analytics and A/B testing included — plus a founder onboarding call on every install.
If your reason for looking at alternatives is that a cap ended your free plan, that is the specific problem we built around.
It is capped at $100 of additional revenue the app generates, per its listing, rather than at a number of orders. You pay nothing until the app has produced that much.
It is better aligned — you only pay once the app has done something. It is also shorter in practice: on a $50 average order value, $100 of attributed revenue is about two upsold orders, so a well-performing app exhausts the allowance quickly.
The attribution model. What counts as app-influenced revenue, over what window, and whether shoppers who would have bought anyway are included. With revenue-based billing, that definition is what your invoice is built on.
Per its listing, $9.99/mo for up to $500/mo of generated revenue — tied to the app's output rather than to your store's order volume.
None of the others bill on generated revenue. The nearest in spirit are the monthly order caps at Selleasy and Wiser AI, which at least reset rather than expiring for good.
