It is very easy to use, it's reliable with good customer support team that answers promptly every time I need help or have any question about optimization of my business processes! The only thing i dislike in this product are some minor glitches but nothing serious at all they should improve them immediately because its not user friendly enough when compared against other similar products out there like Sage 50 etc., you're better off by using something else if your looking into an Inventory Management Software which has excellent features otherwise stick around here as we do provide great value service even after sales where our customers can always call us back again whenever required!! We started implementing optimaT since last 3 years now so far everything works perfectly well no issues whatsoever what-so ever!!
