The best part about this software which I use as an agency owner from India has been that it integrates with our system perfectly without any hassle at all; they have amazing customer support too who are always ready to help! One thing though - there's hardly anything you can customize or do differently when using their service (at least not now). There also isn't much room left after adding so many modules we need right away. Try them out first before taking final decision but if your looking for something that is easy enough to implement then go ahead otherwise don't waste time & money because once implemented nothing comes up again!! Easy integration process between us and WLS services.
