QuickBooks Online searches for the last day you have transacted for the first time you connect to your account. You will be able to test the import by a day of transactions.
You won't see transactions until the day after you process a transaction with your Square account if you have processed nothing in over fifteen days. For example, you will only be witnessing your daily bats from yesterday if you processed transactions yesterday and also one day last week. The batch is available for importation every day thereafter. To learn more about QuickBooks and Square integration, Visit Squarespace Integration with QuickBooks
