The best thing about tallyFY was its ease of use! Nothing at all - I've been able for my entire team who had never used any software before (including me) with minimal training we were up running within minutes after installation- no errors or technical issues whatsoever!! And once setup properly you only need one person doing workflows instead if needing separate admin accounts etc as other systems require which makes life much easier when dealing large teams across multiple locations.- No real downsides but maybe just an annoyance would be being required every 30 days due date reminders so they can remember their anniversary dates? This has meant less headaches during our monthly planning meetings where everyone else uses different programs such as Excel / SOPASoftwareetc.
