# Step 4: Set up Inventory Sync Options

With Inventory Sync enabled, LitCommerce automatically runs a process every 15 minutes to keep the inventory on the Sales Channel in sync with the Main Store. 

It also updates the Sales Channel with any Inventory adjustments made in the Main Store and those resulting from new orders received from the Sales Channels.

**Changes made directly to Marketplace inventory will not be reflected in your Main Store/ LitCommerce.**
{% endhint %}

This article describes how Inventory Sync and other options help you manage the Inventory Synchronization flow from the Main Store to the Marketplace.

## <mark style="color:$primary;">**How to enable Inventory Sync**</mark>

To do this, go to the desired channel in the sidebar menu and click the `Channel Settings` button to find the Inventory Options.

When enabled, the Inventory Sync Options will be applied to all existing listings in the Channel. If not, they will be applied one time when the new listings are added from the Main Store to the Sales Channel.

{% hint style="info" %}
**The quantity will be calculated in sequential order of the inventory sync options.**
{% endhint %}

### <mark style="color:$info;">**Inventory Sync**</mark>

Enabling the Inventory Sync will trigger an automatic process in the LitCommerce system every 15 minutes to scan for new updates in the Inventory in the Main Store and sync them to linked listings in the Sales Channels.

Additionally, the system automatically import orders from Sales Channels to the application, aiming to maintain consistency between the Main Store and connected Channels in LitCommerce.

### <mark style="color:$info;">**Keep Listing Active**</mark>

By default, the Listing Status depends on the Product Status and available Inventory in the Main Store. Toggle this button to keep the linked listing Active on the Channel despite the Product Status in the Main Store.

### <mark style="color:$info;">**Inventory Rules**</mark>

Each Sales Channel has its own restrictions regarding the Quantity. You can set the Inventory for listings by utilizing the Inventory Rules. Here is how to establish them:

* **Automatically adjust the quantities on this channel in relation to the total quantity in your Main Store:** Enter the percentage of the quantity that you want to use from the Main Store in the Marketplace.

* **For No Manage Stock listings:** When the listing is linked to a No Manage Stock product in All Products, the quantity in the Sales Channel will be automatically set to a fixed value.

* **Maximum/Minimum Quantity:** Set up the maximum/minimum quantity to be displayed on the Sales Channel regardless of the actual stock in the Main Store.

* **Automatically set the product on \[Sales Channel] to out of stock:** Set up the listing’s stock status when the quantity reaches a fixed value. Utilize this if you want to have a buffer stock between the Sales Channel and your Main Store.

Some Sales Channels have their own Price Sync options due to their unique features. Head to each Channel Settings for additional information.
