Paychex Payroll to QuickBooks Online: Automated Journal Entry Guide
Paychex Flex offers a QuickBooks Online integration, but like most payroll integrations, it syncs payroll as categorized transactions rather than a single balanced journal entry. Firms that need a proper journal entry for clean month-end close still have to enter it manually.
