ISO Solutions for Managing PTO Balances and Requests

How is everyone tracking employee accrued PTO and managing requests for PTO? We use QB online for payroll and utilize an accrual-based PTO system, which is tracked in QB. However, since we have no need for the time tracking feature in QB thanks to the Aspire Mobile app, we have to utilize an entirely different resource for submitting and approving time off requests. The app we have been using for the last couple years is called DayOff. While it is simple to use and convenient for the crew, it has become a PITA to keep each employee’s accrued and remaining time off balance up to date, as the app does not sync with QB. Has anyone found an easier way to deal with keeping track of time off balances and requests?
