The system is easy to use, fast scan time which makes working life easier for us as it's more efficient than having staff members manually enter data in spreadsheets or other systems like Microsoft Excel etc., no delays when sending out invoices with PDF attachments are sent faster from within this software instead of emailing them through Outlook/Hotmail accounts - also saves valuable office space due high efficiency rate compared woth manual entry methods! Nothing really disliked about ADSS so far though we're only using their services since less then one month now but I can say that everything works fine without any complaints yet.
