The Square app is a one-way connector that automatically integrates your Square sales transactions into QuickBooks Online regularly. Once active, the app keeps track of all transactions in your Square account, including sales, refunds, taxes, tips, and discounts. As such, a third-party paid connected app is needed for the integration.
You may want to find some third-party applications that allow you to Connect your Square account to QuickBooks Online in the Apps for QuickBooks Online webpage or by following this link: https://quickbooks.intuit.com/app/apps/home/en-global/.
