I like that they are very flexible in terms of scheduling, allowing me set my own work schedule within reason - it's not always possible for them do this but when we can have some flexibility with our schedules then great! They also offer several different services including payroll processing so you don't need separate providers if those aren’t required by your business needs as well.
There isn't much about OES at all which makes us hesitant sometimes because there really should be more options available than what their website says or offers currently; however everything works out fine once things get going again after being down due to COVID 19 pandemic situation here locally where i am located now. We were able process paychecks faster since most employers had been closed during quarantine period meaning employees couldn't go into businesses etc., therefore having access via POs was helpful especially given how many people depend upon these checks coming from an outside source instead of directly through bank account/debit card transactions themselves.
