# Supplier constraints

> Define minimum order quantities and pack multiples per supplier-variant, enforced by rules.

**Supplier constraints** capture per-supplier ordering rules at the variant level —
specifically the **minimum order quantity (MOQ)** and the **pack multiple**. Rules then
check that restock and supplier-side plans respect them.

## What a constraint holds

* **Supplier** and **variant** it applies to.
* **MOQ** — the minimum quantity you can order for that supplier-variant.
* **Pack multiple** — the increment quantities must be a multiple of.

At least one of MOQ or pack multiple is set per constraint.

## Rules

Supplier-constraint rules from the catalog check, for example, "variant below MOQ" or
"quantity not a multiple of pack", and **warn** when a plan line violates them.

## Working with supplier constraints

<Steps>
  <Step title="Open supplier constraints">
    Go to **Intelligence layer → Supplier constraints**.
  </Step>

  <Step title="Add constraints">
    Add MOQ and/or pack-multiple rows per supplier-variant (you can import them in bulk).
  </Step>

  <Step title="Attach rules">
    Add the MOQ / pack-multiple rules to the ruleset used by your restock and supplier
    plans.
