The ease of use once you get used it! I wish there was an option that allowed me more than one user access at any given point but other then this its easy peasy when using multiple people!! Nothing really dislike about Cogs as such everything is good so far we have been able find all our issues addressed quickly which has made us very happy customers :) We were looking into new systems after years out dated software had become too slow/crashy etc however nothing else could do what cogswell does without breaking your bank account!
