01The problem

A generous code and a big basket are the same thing

Shopify has never let you put a ceiling on a percentage discount. Merchants have been asking for it in the community forums for years. Every workaround costs you something.

✕ NATIVE

No cap in Shopify.

Support confirms it, repeatedly, with no timeline. A percentage code applies to whatever the cart happens to be.

✕ MARGIN

One order eats ten.

An influencer code of 20% on a 1,500 basket gives away 300. You meant a nice gesture, not a hole in the P&L.

✕ WORKAROUND

Fixed-amount juggling.

Mixing a percentage code with automatic fixed-amount discounts is fragile, confusing to staff, and often just doesn't fire.

✕ SCRIPTS

Scripts are gone.

It was possible on Shopify Plus at 2,000+ a month. Scripts are deprecated, so even that door is closing.

min(%, cap)

MaxOff runs inside Shopify's own discount engine. A Shopify Function calculates the discount at checkout and stops it at your maximum. The buyer sees one clean discount line. Your theme is never touched.

02How it works

Install to a working capped code in under three minutes

  1. 1

    Write the code

    a discount code like SUMMER15, or an automatic discount with no code at all.

  2. 2

    Set the percentage and the maximum

    15% off, never more than 150. MaxOff immediately tells you the cart size where the ceiling starts working.

  3. 3

    Add the usual controls

    start and end dates, usage limits, one-per-customer, which products it applies to, what it combines with.

  4. 4

    Test before you send it out

    build a basket in the cart tester and see the buyer's checkout side by side, with and without the cap.

  5. 5

    Shopify applies the cap at checkout

    server-side, on every order, on every theme. Nothing is added to your storefront.

  6. 6

    Watch what you kept

    every capped order is logged with the amount the cap saved you, per code and per month.

05Insights

Know exactly what the ceiling was worth

A cap only pays for itself if you can see it working. MaxOff answers four questions, every month, without you exporting anything.

Where the cap starts

For every code, MaxOff shows the cart value at which the ceiling begins to bite — 15% with a 150 maximum starts working above 1,000. It is the number nobody explains, and the one that decides whether your cap is set sensibly.

Which orders it caught

Every capped order is listed with the cart total, the discount the customer would have received, what they actually received, and the difference. If a code is being shared on a coupon site, you will see it here first.

06Pricing

Flat monthly price. No transaction fees, no revenue share.

Apps that take a cut of every discounted order punish you for succeeding. MaxOff charges the same whether you run one code or fifty.

07FAQ

The questions merchants actually ask

What exactly does MaxOff change?

Only the amount of the discount. The code, the products, your prices, your theme and your URLs are untouched. At checkout, Shopify applies the smaller of your percentage and your maximum.

Will this slow my store down?

No. MaxOff adds nothing to your storefront — no script, no snippet, no app block. The cap is calculated by Shopify on its own servers while the order is being priced.

What happens on a cart that is under the maximum?

Nothing. The customer gets the full percentage as normal. The cap only appears on the orders that would have cost you more than you intended.

Does the customer see that the discount was capped?

They see one clean discount line. You choose the note underneath it — the default is "Discount capped at maximum amount" — or you can leave it blank and show nothing.

Does it work with automatic discounts, not just codes?

Yes. A capped discount can be a code the customer types, or an automatic discount that applies on its own.

Can I combine it with my other discounts?

Yes, with the same combination rules Shopify already gives you. When discounts stack, MaxOff caps its own share only — it never touches the other discount.

What data can MaxOff see?

Discounts, and the orders those discounts were used on, so it can report what the cap saved you. No customer payment details, no financial account data.

What happens if I uninstall?

The caps stop applying and the discounts stay in your Shopify admin as ordinary percentage discounts, where you can edit or delete them. Nothing is left behind in your theme, because nothing was ever put there.

Is MaxOff on the Shopify App Store yet?

Not yet — we are in early access while we finish the build. Early access is free, and early-access stores keep a discounted rate when we launch.
