# Inventory sync rules

When syncing products to TikTok Shop, inventory will be updated based on your configured sync rules. These settings are especially useful for preventing overselling.\
You can configure them under:\
**Settings → Product → Inventory → Sync rules**

## Quantity

You can choose to sync a **percentage** of the available inventory from your source locations.

* By default, **100%** of available inventory is synced.
* You can adjust this to any percentage (e.g., sync 80% to keep a buffer in Shopify).

Behavior based on Shopify settings:

* If **Track quantity** is **enabled** in Shopify, we will sync the **available** inventory from the mapped locations.
* If **Track quantity** is **disabled** or **Continue selling when out of stock** is **enabled**, we will sync the maximum inventory allowed by TikTok Shop: **999,999**.

Examples: Track quantity is enabled in Shopif&#x79;**,** Quantity adjustment: 80%

Final synced quantity to TikTok Shop: **788** (985\*80%)&#x20;

## Location mapping

You can map your **active Shopify warehouse locations** to your **active TikTok Shop pickup warehouse**. This ensures accurate inventory sync across platforms. Syncing inventory from your active Shopify warehouse locations helps ensure accurate stock levels on TikTok Shop.

{% hint style="info" %}
This configuration applies globally to all products and **cannot be customized per product**.
{% endhint %}

Examples:&#x20;

* In Shopify, you have two active locations:
  * Location A: 100 available inventory
  * Location B: 200 available inventory
* In TikTok Shop, you have two active pickup warehouses:
  * Warehouse: α (default)
  * Warehouse: β&#x20;

If you set the sync rule as **All active locations → α**, then:&#x20;

Synced inventory to TikTok Shop = 100 + 200 = **300**, reflected in warehouse **α.**

Examples:&#x20;

* In Shopify, you have two active locations:
  * Location A: 100 available inventory
  * Location B: 200 available inventory
* In TikTok Shop, you have two active pickup warehouses:
  * Warehouse: α (default)
  * Warehouse: β&#x20;

If you set the sync rule to **sync 80% of available inventory** and **Location A → β**, then

Synced inventory to TikTok Shop = 100\*0.8=80, reflected in warehouse **β.**
