Short answer
Roughly one Shopify app in seven does not charge a flat monthly fee. It meters
you — per order, per page view, per product, per credit, or as a percentage of the revenue it generates. The
number on the listing is a starting price, not your bill.
That is not automatically bad. Metered pricing means a quiet
month costs you little. But it produces two traps: plans that auto-upgrade when you cross a
threshold, and cheap tiers that become the most expensive option once you grow. We have done the
arithmetic on 13 apps below, including the exact volumes where each one flips.
The five ways Shopify apps meter you
Per order
A monthly fee covering a fixed number of orders, then overage — or an automatic jump to the next tier.
Track123, Navidium, EliteCart, AddressHero, ReConvert
Percentage of revenue
The app takes a cut of the sales it generates. Costs nothing when it does nothing.
Magical Make an Offer, Offerly, Post Purchase Upsell Hero
Per unit of activity
Charged per page view, per email, per validated address, per updated product.
StoreFAQ, AddressHero, Datify, PreOrder Now
Catalogue size caps
Your tier is set by how many products you have, not by how much you sell.
StoreSEO, SEOmatic, Rubik
Credits
You buy a credit balance. The hard part is that most listings never say what one action costs.

Genuinely flat
One price, no overage, no revenue share. Rarer than you would expect.

The trap: when the cheap plan becomes the expensive one
This is the part nobody publishes. On several apps, the entry tier costs more than the tier above it
once you pass a certain volume, because the overage rate is worse than the next plan’s flat rate. Here is where each
one flips.
| App | Metered on | The flip point |
|---|---|---|
 Track123 |
Orders ($0.05 each over cap) | Above 1,100 orders/mo, the $49 Advanced plan beats $9 Growth plus overage |
 StoreFAQ |
FAQ page views | Above 940 views/mo, $14.99 Growth beats $7.99 Professional. Above 6,700, the $49.99 unlimited plan wins |
 AddressHero |
$0.04 per order (Pro) | At 250 orders/mo Pro costs the same as $9.99 Lite — but the two tiers do different jobs |
 StoreSEO |
Product count | At 251 products you leave the $39.99 tier — and the next one is $249.99 |
 Magical Make an Offer |
1% of offer revenue | Above $2,000/mo in negotiated sales, a $19.99 flat rival costs less |
 EliteCart |
Orders (200 included) | The $29.99 headline holds only under 200 orders/mo; the listing cites +$10 at 500 |
Our own arithmetic on published list prices,
verified 7 August 2026. Flip points assume the app is your only cost and that overage is charged as published.
The exception that proves it can be done well
Post Purchase Upsell Hero — the rate falls as you grow
2.5% on the first $20,000 of app-generated
upsell revenue each month, then 0% above $20,001. The bill is capped at $500 however much it sells,
so the effective rate falls to 1% at $50k and 0.25% at $200k.
Almost every other metered app does the reverse: the more successful you are, the higher your effective rate.
Upsell Hero is the only app in our dataset where growing makes the app proportionally cheaper. It is also free to
install, so it costs nothing until it generates something.

Auto-upgrade: the charge you did not approve
Some per-order apps do not bill overage — they move you to the next plan automatically. Navidium’s
Essential tier states plainly that it “automatically upgrades to the next billing plan when you exceed 500 orders in
your billing cycle.” Cross the line in a good month and your $29.99 becomes $49.99 without any action from you.
To be fair to Navidium, this is disclosed on the listing, the pay-as-you-go option is genuinely generous
— free to install, $0 up to 50 orders a month — and it takes no revenue share, letting you keep 100% of
the protection fees you collect. That is a better deal than most of its category. But you should know the upgrade
is automatic before your first busy month, not after it.

Credits: the model you cannot calculate
Credit pricing is the least transparent thing in the App Store, because the listing tells you how many credits
you get and almost never what one action costs.
ChatGPT AI Product Description is a good example, and a good app — 4.9 stars from 457 reviews, Built for
Shopify. Its free plan gives 100 credits a month and Basic gives 2,000 for $14. But the listing never states how
many credits one product description consumes, and it plausibly varies: generating from a product image, or with a
web search, is more work than plain text. The marketing says roughly $1 per 100 descriptions, which implies a rate,
but you cannot verify it before installing.
How to price a credit app in ten minutes
- Install on the free plan.
- Note the credit balance.
- Run exactly ten items, using the settings you actually intend to use.
- Check the balance again. Divide the difference by ten.
- Multiply by your real catalogue size. Now you know which tier you need.

Percentage models: cheap until they are not
Revenue-share pricing is the fairest-feeling model in ecommerce — you pay only when the app earns. It is
also the one that punishes high-ticket sellers hardest, because the app’s workload does not change with your order
value but its fee does.
1% of offer revenue vs a $19.99 flat fee
The crossover is about $2,000 a month in
revenue closing through the app. Below it, percentage wins. Above it, flat wins — and keeps winning.
One sale of a $4,000 guitar through a 1% app costs $40. The same app on a store selling $40 t-shirts costs 40
cents a sale. Same app, same work, a hundredfold difference in what you pay for it. If your average order value is
high, read the fee line before the feature list. We worked through this in detail in
the make-an-offer app comparison.
Work out your real bill in five minutes
- Find the meter. On the listing, look past the headline price for the words orders,
per extra, usage charges, credits, products or a percentage. If any appear, the
headline is a floor, not a price. - Get your real number. Last month’s orders, your product count, your monthly sessions. Not your
best month and not your hoped-for month. - Calculate the tier above too. The flip points in the table above exist because nobody does
this. The cheaper plan is often the more expensive choice. - Check for auto-upgrade. Search the pricing block for “automatically”. If it upgrades itself,
budget for the tier above your current volume. - Check whether the cap is a cap. Some apps cap overage (Lury caps at $99/month); most do
not. - Re-check quarterly. Your volume moves and so does app pricing. A tier that was right in
January is often wrong by June.
The bottom line
Metered pricing is not the enemy — it is the uncalculated meter that costs you. Three rules cover almost every case.
If your order value is high, avoid percentage models. The app does identical work on a $40 order and a $4,000 one; only your bill changes.
If your volume is growing, price the tier above the one you need today, and check whether it upgrades itself.
If the app sells credits, measure the burn rate on ten items before you pick a plan. No listing will tell you.
Frequently asked questions
What is usage-based pricing for Shopify apps?
Usage-based pricing charges you according to how much you use an app rather than a flat monthly fee —
typically per order processed, per page view, per product, per credit consumed, or as a percentage of the revenue
the app generates. Costs scale with your store’s volume, so the price on the listing is a starting point rather
than your actual bill.
Do Shopify apps charge per order?
Some do. Track123 includes 300 orders on its $9 plan and charges $0.05 per extra order. EliteCart includes 200
orders at $29.99 and scales above that. AddressHero’s Pro tier is $0.04 per order with no monthly fee. Navidium
moves you to the next plan automatically once you pass 500 orders in a billing cycle. Always check what the
included allowance is before installing.
How do I find out how much a Shopify app will really cost me?
Take your actual monthly volume — orders, products, or sessions depending on what the app meters —
and calculate the cost on both the tier you think you need and the tier above it. Overage rates on cheap plans are
often worse than the flat rate of the next plan up, so the entry tier can be the most expensive option. For credit
based apps, run ten items on the free plan and measure the balance change.
Can a Shopify app upgrade my plan automatically?
Yes, and some do. Navidium’s listing states that its Essential plan automatically upgrades to the next billing
plan when you exceed 500 orders in a billing cycle. This is disclosed on the listing, but it is easy to miss, and it
means a strong sales month can raise your app bill without any action from you. Search the pricing section for the
word “automatically” before installing.
Is usage-based app pricing bad?
No — often it is fairer. You pay nothing in a quiet month, and free-to-install apps carry no risk if the
app turns out not to suit your store. Post Purchase Upsell Hero even reduces its effective rate as you grow,
charging 2.5% on the first $20,000 of upsell revenue each month and nothing above that. The problem is not the model
itself, it is that the listing shows you the entry price and leaves the arithmetic to you.
Where do app charges appear on my bill?
App subscription and usage charges appear on your regular Shopify invoice rather than being billed separately by
the developer, and recurring and usage-based charges are billed every 30 days. Because they arrive bundled with your
Shopify bill, metered charges are easy to overlook — which is exactly why it is worth calculating them before
you install rather than discovering them afterwards.
How we researched this
We scanned all 143 apps in our database for metered pricing language and found 20 that charge by usage rather
than a flat fee. For every app named on this page we then re-read the live Shopify App Store listing on 7 August
2026 and took the plan names, allowances, overage rates and percentages directly from it — not from vendor
marketing, and not from our own older notes. That re-check caught review-count drift on four apps, which we
corrected at the same time.
All flip points and cost figures are our own arithmetic on those published list prices. They assume overage is
charged exactly as published and ignore taxes and annual discounts. App pricing changes without announcement, so
treat every number here as accurate on the date above and verify on the listing before you install.
Prices verified against the Shopify App Store on 7 August 2026. This page contains partner
links to some of the apps named; others link to their App Store listings and earn us nothing. Partner links never
cost you more, and they do not change the arithmetic — several apps we are paid for appear here specifically
because of how their pricing behaves at scale.
