SyncPenguin is an affordable and reliable tool to sync Square inventory quantities between two stores. We ensure all purchase or manual stock inventory level changes are correctly reflected in both stores, and you never end up overselling your products.

Please note that this sync doesn't include any other product data like images, descriptions, or prices. We simply match products and variants by SKUs between the two synced stores and keep the quantity in sync. This means that products that you want to have synced must have matching SKUs, and the SKUs must be unique within a store.

This guide explains in detail how to create, configure and start the sync.

If you'd like to start syncing right away, feel free to create an account and set up the sync on your own. Go back to the guide in case of any ambiguity or questions. You can also contact us for any questions, requests, or feedback.

# Step 1. Create a SyncPenguin account

The first step is to create a SyncPenguin account. We offer a free 14-day trial (without a credit card) to make sure everything works well before your commitment. Please follow the link below to create an account.

# Step 2. Create the sync

The next step is to create a sync in the Synchronizations section of the dashboard by clicking the + New sync button. You'll see a wizard page, where you have to do the following three steps:

  • Choose Square Inventory Quantities for the first app.
  • Then choose Square Inventory Quantities for the second app.
  • Then click the Create button.

# Step 3. Provide access to Square

Now that your sync is created, the next important step is to grant SyncPenguin access to your store data. You'll see two Access & Settings sections for both apps involved in the sync. Below we explain how to connect and configure accounts.

How to connect Square?

The Square Inventory Quantities access & settings section will look like this:

Please make sure both apps are properly connected before starting the inventory sync.

DATA SECURITY

If you're concerned about the security of your private data, please check out the Security Practices page.

# Step 4. Sync settings

In the Sync settings section you have the ability to adjust some of the default properties of your integration flow:

  • The name of your sync
  • Sync direction (two-way or one-way)
  • Sync interval (by default the sync is triggered every 10 minutes)
  • Proceed on error (should the sync ignore errors or retry)

# Step 5. Start the sync

The last step is to start the sync. To do that, click the Start sync button.

You'll then be prompted with the following four options:

  1. Only sync new data, meaning SKUs that will be updated starting from now.
  2. Merge Square Inventory Quantities A to Square Inventory Quantities B: take all Square Inventory Quantities A and add/merge them to Square Inventory Quantities B. Here A and B are used to distinguish the two data sources.
  3. Merge Square Inventory Quantities B to Square Inventory Quantities A: similar to the previous option but in the opposite direction.

We recommend running the merge in either direction to ensure the stock levels are initially the same for all matching SKUs.

We'll be checking every 10 minutes for changes in your data.
What should we do initially with already existing inventory?

Once you make your choice, just click Start sync. In case you decide to do the initial merge, it'll be instantly queued. Once it's done, we'll be checking for inventory changes every now and then (depending on the sync interval specified) and syncing accordingly. Each sync execution can be seen in the Sync history at the bottom of the sync page.
