Shopify's built-in quantity rules cover a narrow slice, and only for B2B on Plus. Here is exactly where the two overlap and where they do not.

**Short answer.** Shopify's native quantity rules are available on Plus, tied to B2B catalogs and price lists, and cover a minimum, maximum and increment on quantity. Prime MOQ works on any plan, applies to both retail and B2B checkouts, and adds value-based, weight-based and repurchase limits plus custom messaging and styling.

## Key takeaways

- Both can enforce a minimum, maximum and increment on quantity for a product.
- Native quantity rules require Shopify Plus and a B2B catalog. Prime MOQ does not.
- Only Prime MOQ covers cart value, shipping weight and cross-order repurchase caps.
- Native rules use generic Shopify UI text. Prime MOQ has per-language custom messages and styling.

## The short answer

Shopify's native quantity rules, available on Shopify Plus and tied to B2B
catalogs and price lists, cover a narrow slice of what Prime MOQ does, and only
for B2B storefronts.

Prime MOQ works on any plan, applies to both retail and B2B checkouts, and covers
quantity, value and weight-based limits plus repurchase caps, rather than only a
minimum, maximum and increment on quantity.

## Where they overlap

Both can enforce a minimum, a maximum, and a step increment on **quantity** for a
product.

## Where Prime MOQ goes further

| Capability | Shopify native quantity rules | Prime MOQ |
|---|---|---|
| Available on standard, non-Plus plans | No | Yes |
| Applies to regular retail checkout, not just B2B | No | Yes |
| Value-based cart total limits | No | Yes |
| Weight-based limits | No | Yes |
| Repurchase caps across separate orders | No | Yes |
| Per-language, customisable message text | No, generic Shopify UI | Yes |
| Scope by tag, vendor, product type, price range or metafield | Limited | Yes |
| Custom styling of the limit message | No | Yes |

## When you might use both

If you are on Shopify Plus with a B2B catalog, native quantity rules are a
reasonable baseline for pure per-product quantity increments tied to a specific
B2B price list.

Prime MOQ is the better fit whenever you need value or weight-based limits,
repurchase enforcement, custom messaging and styling, or simply want the same rule
logic applied uniformly across retail and B2B checkouts instead of maintaining two
separate systems.

## FAQ

### Do I need Shopify Plus to set a minimum order quantity?

No. Shopify's own quantity rules need Plus and a B2B catalog, but Prime MOQ works on standard plans and covers retail checkouts too.

### Can I use Shopify's native quantity rules and Prime MOQ at the same time?

You can, but keep them off the same products to avoid two systems enforcing overlapping constraints on one item. Using native rules for B2B price-list increments and Prime MOQ for everything else is the cleaner split.

### Do Shopify's native quantity rules apply to retail customers?

No. They are tied to B2B catalogs and price lists, so retail checkouts are unaffected by them.

### Can Shopify's native rules limit cart value or weight?

No. They only cover quantity, in minimum, maximum and increment form. Value and weight thresholds need an app.

### Can I customise the message Shopify shows for a native quantity rule?

No. It uses generic Shopify UI text. Prime MOQ has per-language message fields per rule, plus a global styling page.

### Which one should I use for case packs?

Either can express an increment on Plus with a B2B catalog. Prime MOQ is the choice if the case pack also applies to retail shoppers, if you want the carton size explained in your own wording, or if you want to combine it with a minimum in the same rule.

**Best for:** Merchants on Plus deciding whether native quantity rules are enough, and merchants on standard plans confirming they have an option at all.
