I like that it automatically calculates sales tax when you enter your items into POS system (which can be useful if they don't have any employees). It's easy to use as well! Sometimes there are some minor bugs but nothing serious or hard-to fix at this time - just make sure everything works fine before using in real life situation; so far all my tests were successful with no issues found yet while operating actual store/business. Easy way how calculate taxes without having employee present who knows about such things by hand calculations etc.; plus dinetapos allows me manage inventory level very easily via barcode scanner instead manual counting each item one after another during business hours only ;-).
