Project management system and CRM system

Best is how much they pack into one app.

UPDATE: After trying to use it for months, I've abandoned this software. WAY too buggy and frustrating; settings disappearing, clients not able to complete payment, and more. And if you don't use your account for several days, they want to delete it. (What made me choose Flowlu was the "all-in-one" nature of the platform. They have packed SO MUCH into this business management suite. I genuinely hope I do not find any reasons ever to need another service.)
