Your Square POS will serve as the main source for all product information (prices, quantities, etc.) across these platforms. Follow the steps below to configure the M2E Multichannel Connect app. ## Link your Square POS account [Sign up for the M2E Multichannel Connect account](https://m2e.cloud/login) by linking your Square POS profile. [![Link your Square POS account](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_1.webp)](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_1.webp) After clicking the **+Connect** button, choose whether you want to link a Sandbox or a Production account. You will be redirected to the Square website. Log in to your account and confirm that you grant the app access to your profile information. Then, you will be redirected back to the app. A confirmation message will appear if your Square account is successfully connected. ## Connect Channel accounts Go to the *Dashboard* tab and follow the setup guide steps listed there. Click **Connect Marketplace Account** to link your eBay, Amazon, Walmart, TikTok Shop, Kaufland, or Temu seller profiles.

Disabling this feature means the app won’t adjust the stock levels for your items, increasing the risk of overselling.

If no match is found, you can link the items manually. Simply click the **View Not Linked Products** button under the *Link Products* section. [![Link existing products in Square POS](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_4-scaled.webp)](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_4-scaled.webp) You will be redirected to the *Listings* tab, where you can complete product linking. If your products aren’t linked, the app won’t be able to properly synchronize your inventory and orders. > 💡 For detailed instructions on linking products, see [here](/docs/link-channel-items/). ## Synchronize products You need to enable synchronization for previously linked products to ensure your inventory remains up-to-date on marketplaces. Item sync provides automatic product data updates from your Square POS to Amazon, eBay, Walmart, TikTok Shop, Kaufland, and Temu. To activate synchronization, click the **View Not Synced Products** button under the *Synchronize Inventory* section. [![Synchronize Square POS products](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_5-scaled.webp)](https://docs.m2ecloud.com/wp-content/uploads/2024/10/Square_POS_User_Guide_Step_5-scaled.webp) You will be redirected to the *Listings* tab, where you can turn on inventory synchronization for needed products individually or in bulk. > 💡 For detailed instructions on enabling inventory sync, see [here](/docs/enable-sync-for-channel-items/). Once your products are linked and synchronized, your setup is complete. You can then [manage product information](https://youtu.be/EV_ILEltYC8) and [fulfill marketplace orders](https://youtu.be/Ep16o5xZj1c) directly from your Square POS. ## List products on Channels With M2E Multichannel Connect, you can list products from your Square POS on eBay, Amazon, or other marketplaces and expand your product range.
