People who don't care about professional

Be aware that Gaap sellers will do their best to take you in their system, forgetting to let you know little things which are going to be a nightmare in the future. They also say that their system is compatible with different accounting softwares but actually it is not. And then, it is too late because you are engaged for 5 years! I'm really astonished to see how their don't care of problem generated by their system on my business!
