## Role-based rules

 

**Settings → Quantity & Pricing → Advanced rules → Store-wide role overrides** lets each role, including *Guest (not logged in)*, override min / max / step / default store-wide. The same table exists per product under the *Quantity & Pricing* tab. Typical setup:

 
 

| Role | Min | Step |
| --- | --- | --- |
| Customer (retail) | 1 | 1 |
| Wholesale | 24 | 12 |

 
 

A user with several roles gets the most restrictive value per field.

 

## Category rules

 

Edit a category under **Products → Categories** and fill the **Quantity & Pricing** fields plus a **Priority**. When a product sits in several categories, *Settings → Advanced rules → Category conflict* decides: **Priority** (highest-priority category wins per field) or **Most restrictive** (highest min, lowest max, largest step). *Include parent categories* also evaluates ancestors.

 

## Cart-level rules

 

Limit the whole cart rather than a line: minimum / maximum **items** and minimum / maximum **subtotal**. Shoppers see the message in the cart and, if *Block checkout* is on, cannot proceed until the cart complies. Works in classic and block checkout.

 

## Decimal quantities and units

 

Turn on **Allow decimal quantities** on a product to sell `1.5` kg or `2.25` m. Add a **Unit label** (`kg`, `m`) and it appears in the quantity hint, price table and, with *Show unit label in cart*, the cart. Step can be decimal too (`0.25`).
