I like how easy it is for me as well as my customers to use this product, in regards of billing or invoicing we are able make quick payments through our bank account without any issues at hand. Also using their API's they can process orders directly from us which helps greatly with having less manual work involved when sending new projects out over email such as creating quotes etc.. Sometimes there could be some lag time between logging into your dashboard but other than those minor hiccups everything works perfectly fine! It has helped cut down on much more paperwork needed within offices while maintaining transparency throughout each project phase along side being extremely user friendly.
