Its integration with other major products is great as it lets you use them in your day to Day work which help me get things done quickly without having any issues at end of day or week time when we want to close our account for that particular month/week. I have found nothing much useful about this product yet but will surely update after using few more weeks! So far so good i haven't seen anything negative or not satisfied enough even by its price tag also compared to what they are charging their users every now n then one should be happy if he got everything right from his choice rather than comparing only pricing factors. We were facing some problems regarding accounting related stuffs like VAT calculation etcetera while doing business globally. And since graphit has provided us complete solution including tax management system where our client can manage taxes easily through website itself The customer service is amazing! They are always willing to help you out with any issues that come up in your account. I have found it very easy to use as well. Nothing really at this time but if you think about using graphite for other services such as email or CRM then be sure to do so because they provide great support. Email management has been much more efficient since switching over from MailChimp to Graphite.
