# Limits

> What checkout rules can't do, set by Shopify: Shop Pay, POS, draft orders, logo methods, local delivery, express and Plus-only conditions.

Source: https://backtrackhq.com/docs/rules/limits/

Checkout rules run inside Shopify checkout, so Shopify sets some
limits. This page lists them in one place. Each rule page also shows
its own limits in the **Limitations** card.

If a rule seems to do nothing, a limit on this page is often the
reason. Check here before you change the rule.

## Which stores can use rules

- Rules work on all Shopify plans except Shopify Starter. You don't
  need Shopify Plus, not even to hide express payment methods.
- A few conditions need Shopify Plus. See
  [Conditions that need Shopify Plus](#conditions-that-need-shopify-plus).

## Where rules don't run

### Shopify POS

Rules don't run in Shopify POS. They only run in the online checkout.

### Draft orders

The **Limitations** card says:

- "Payment rules don't support draft orders."
- "Shipping rules don't support draft orders."
- "Validation rules don't support draft orders."
- Discounts: "Draft order checkouts are not supported."

What this means in Shopify:

| Rule type | While staff build the draft in the admin | When the shopper pays through the draft's checkout |
| --- | --- | --- |
| Payment and shipping | Not applied | Applied |
| Validation | Applied | Applied |
| Discount | Not applied | Not supported |

So "don't support draft orders" on the card means the admin side. It
does not mean the rule is ignored everywhere.

### Inside Shop Pay

"Payment rules aren't compatible with Shop Pay." Inside Shop Pay,
payment methods can't be changed apart from gift cards.

What to do: test your payment rule in the normal checkout, not in Shop
Pay.

## Payment method limits

### Logo methods can't be renamed

"You can't rename payment methods that have logos as a name." For
example Shop Pay, PayPal, Amazon Pay, Apple Pay, Google Pay and gift
card.

What to do: hide the method instead, or rename only text-named
methods.

### Some logo methods can't be moved

"Due to Shopify limitations, few logo based payment methods can't be
moved for example Shop Pay." Reorder the other methods around them
instead. Express and wallet methods can be hidden, but not
reordered.

## Shipping method limits

### Local delivery and local pickup

Shipping rules can hide, rename and reorder local delivery and local
pickup options too, for example with the **Hide local pickup for
international** use case.

### Reordering can change the selected rate

By default, the cheapest shipping option shows first and is
pre-selected. Reordering can move it down.

What to do: after you save a reorder rule, check checkout once to see
which rate is picked first.

## Express checkout limits

- "For logged in customers this customization only work on their
  first order."
- "Carts that do not require shipping is not compatible with this
  customization."
- The two "(One-page checkout)" actions only work on one-page
  checkout, and need a manual payment method or shipping rate set up
  in Shopify. See
  [Hide express checkout options](https://backtrackhq.com/docs/rules/hide-express-checkout/#actions).

## Discount limits

- Product discounts: "Applies per cart line, not the order total."
- Order discounts: "Applies to the entire order subtotal."
- Combined and tiered rules: "Combining with other discounts follows
  the Combinations settings."
- Tiered rewards: "Minimums use cart prices before any discount." and
  "A cart line takes one product discount, so a bigger product
  discount can replace a free gift."
- A discount code can be rejected only when the shopper enters it,
  using **Discount code rejection** on an automatic order discount.
  Rejecting a code by shipping method is not possible. See
  [Example: block discount codes](https://backtrackhq.com/docs/rules/example-block-discount-codes/).

## Conditions that need Shopify Plus

Two conditions are marked "(Plus required)":

- **Selected payment method (Plus required)**
- **Discount code or automatic discount (wildcard, Plus required)**

They need checkout extensibility, which means Shopify Plus or a
development store. They don't match in accelerated
checkouts such as Apple Pay or Google Pay.

## How many rules you can run

- Your plan sets how many rules can be active. Drafts don't count.
  See [Plans and billing](https://backtrackhq.com/docs/get-started/plans-and-billing/) and
  [Rule limit reached](https://backtrackhq.com/docs/help/rule-limit-reached/).
- Shopify allows at most 25 active functions of each type on a store.
  This number is shared with every app on the store. If other apps
  use some, fewer are left for AndOr.

## Rule size

Shopify gives each rule up to 10 KB of settings at checkout. Long
lists of addresses or values use the most space. The **Rule size**
card shows how much of the 10 KB the rule uses. If you get close,
split the list into two rules. You can't save a rule that is over the limit.
See [Rule size](https://backtrackhq.com/docs/building-rules/rule-size/).

## Rule sets

Each rule set offers a different group of conditions, because of the
Shopify Functions input size limit. If a condition you need is not
in your rule set, pick another set, or make a second rule.
