Warehouse connections in Sumtracker allow you to sync inventory between specific warehouses in Sumtracker to your store. By setting up these connections, you can ensure the inventory levels are synced between your Sumtracker warehouses and your store, helping to keep stock levels accurate across platforms.

To access and manage warehouse connections, navigate to the store's settings page in Sumtracker and click on the "Warehouse Connections" tab. Here, you can manage which warehouses are linked to the store.

Shopify allows multiple locations to manage inventory independently. In Sumtracker, each of these Shopify locations can be connected to a corresponding warehouse. When inventory is updated at a certain warehouse in Sumtracker, it automatically updates the linked Shopify locations with the correct stock levels.

You have multiple ways to configure a Sumtracker warehouse to work with your Shopify locations, depending on how you want to structure your inventory system. Here's a brief overview of the possibilities:

Additionally, a Shopify location can remain unlinked from any Sumtracker warehouse as well. In this case, no Sumtracker inventory will be synced to that location, allowing you to manage it independently directly in Shopify.

All of these configurations can be set up from the Warehouse Connections page. Let’s see more about each of them below. We will also see what happens when a new location is added to to your Shopify store and when the fulfillment location is changed for an order in Shopify.

You can link the same location to multiple Shopify stores with Sumtracker. This allows you to manage inventory from the same physical location across different Shopify stores, ensuring seamless synchronization.

For example, if you have a location called "Denver," you can link it to both your Shopify Store A and Shopify Store B. Sumtracker will manage and sync the inventory for this warehouse across both stores automatically. If a sale is made on one store, Sumtracker will automatically update the inventory across all connected stores.
​

When you link the same Sumtracker warehouse to multiple locations in your Shopify store, the same inventory is reflected across all those locations. This can lead to inflated inventory numbers on Shopify, so it’s important to understand how this works.

For example, let’s say you have a warehouse called "DENVER" in Sumtracker, and it’s linked to both the Denver and Ohio locations in your Shopify store. If the inventory at the Denver Warehouse is 624 units in Sumtracker, this same inventory count will be displayed for both the Denver and Ohio locations in Shopify.

In Shopify, this would appear as follows:

However, since it's the same stock being reflected in both locations, Shopify will show a total of 1,248 units (624 units for Denver + 624 units for Ohio). This Total is misleading because both locations are drawing from the same inventory pool of 624 units. If a sale is made from either the Denver or Ohio location, Sumtracker will update the inventory across both locations to reflect the sale.

For example: If 50 units are sold from the Denver location, the inventory will update to 574 units, and both the Denver and Ohio locations will display this updated count. The total across both locations will also adjust to 1,148 units (574 + 574).

This setup allows you to manage inventory centrally from the Denver warehouse, but you should be cautious of the inflated total count shown in Shopify, as it represents the same stock being allocated to multiple locations.

If a Shopify location is not linked to a warehouse in Sumtracker, the inventory for that location will not sync, meaning no updates will be reflected in Shopify for that specific location until the connection is made.

Example: Let's say you have three locations in Shopify: Nevada, Kansas, and Denver. You have already linked your Nevada and Kansas locations to corresponding Sumtracker warehouses, but you have not linked the Denver location.

Once you link the Denver location to a Sumtracker warehouse, future inventory updates will reflect correctly on Shopify for that location.

When a new location is added in your Shopify store, Sumtracker automatically detects this addition and sends you an email notification to alert you about the new location. However, this new location remains unlinked in Sumtracker until you take action. You’ll be able to see the newly added location listed in the "Warehouse Connections" tab of your store’s settings, but inventory will not sync until you manually link it to a warehouse in Sumtracker.

To start using this new location in your inventory management, you have the option to link it to any existing Sumtracker warehouse or create a new one specifically for it.

Before linking, it is essential that the inventory levels in the chosen Sumtracker warehouse are accurate and up-to-date. Once the new location is linked, Sumtracker will start syncing the inventory from the selected warehouse to this Shopify location. This means the stock levels in the connected warehouse will be reflected in the new Shopify location. If the inventory is not properly updated before the connection, incorrect stock levels may be displayed on Shopify, which can lead to overselling or stock discrepancies.

When the fulfillment location for an order is changed in Shopify, it will automatically update in Sumtracker after the order is fulfilled in Shopify. The inventory will then be deducted from the updated warehouse correctly.

If you need the location to update immediately in Sumtracker, you can manually refresh the order, and the inventory will be deducted from the new location right away. Check this article on how to refresh orders manually.

Sumtracker also integrates with platforms like WooCommerce, Etsy, BigCommerce, eBay, and Amazon. Unlike Shopify, these platforms do not support inventory management at multiple locations. Instead, Sumtracker updates the combined stock levels from the connected warehouses to your store.

For instance, if you have multiple warehouses connected to your store—Kansas with 30 units and Nevada with 20 units—Sumtracker will calculate a total inventory of 50 units and sync this total to your store.

You can choose which warehouses will update the inventory to your store. For instance, if you want to use only the inventory from Kansas and Nevada for your BigCommerce store, you can set this by creating a warehouse connection specific to that store.

When an order is placed, Sumtracker deducts inventory from the linked warehouses based on the warehouse priority set in Sumtracker. If you’ve set Nevada as the highest priority, inventory will be deducted from Nevada warehouse first. If the product is out of stock at the Nevada warehouse, the inventory will then be deducted from Kansas.

The warehouse priority can be set from Settings > Warehouses > Set Warehouse Ordering. You can simply drag and drop the warehouses to set the priority, with the priority decreasing as you go down the list.

Sumtracker supports integration with Fulfillment by Amazon (FBA) as well, where a separate warehouse is created for each Amazon marketplace. FBA warehouses in Sumtracker are treated as individual entities for each marketplace (e.g., Amazon US, Amazon UK).

Inventory at each FBA warehouse is updated separately. Sumtracker keeps the stock levels for each Amazon marketplace independent, ensuring accurate inventory tracking per marketplace.

To setup the FBA warehouses in Sumtracker, head over to the Warehouse Connections tab in the store settings and click on “Edit FBA warehouse connections”. You can then select the marketplaces you want to track and corresponding warehouses will automatically be created in Sumtracker.

If the inventory is updated in your FBA portal, the inventory will be synced to Sumtracker and can be seen under that warehouse in Sumtracker.
