I like that it's easy to navigate, quick quotes turnaround time, ability to customize reports as needed. There are some things about this software we wish could be improved upon but they have been working hard at improving their product over the past couple years so there should hopefully not too many issues in future upgrades. We use calcuquote primarily for quoting purposes with our customers and suppliers. The most useful feature of this program is its ease of navigation from one task to another within the same screen/window which helps us keep track of multiple tasks quickly without having to open up several windows or tabs while multitasking. Also being able to see all information pertaining to each job at once instead of opening new screens would help save time if you were doing more than 1 project at a time. This has also helped speed up communication between myself and my team members since we don't need to do separate emailing just because someone needs something done differently then what was originally discussed.
