We started with a pilot for our payroll department. It essentially takes the transactions that come into our payroll department on Fridays and Mondays, and sorts through those transactions. If there are any discrepancies or errors based on the defined criteria, it notifies the payroll department, and they can rectify those. Otherwise, paychecks don't process.
Other than that, we have some data migration between Excel spreadsheets that we do, and we have contracts that we host on a web server that, if they don't have transactions for the same period of time, we have the automation go in and close those contracts out so the transactions can't go against them.
