How can I make sure that I'm billing my clients correctly as a freelancer?

[Btaliat]

One of the issuea that do face freelancers is the fact that they know how to bill their clients. Some don't even know whether they are doing it right or not. That's why they need to have a clue on how to know if they are doing it right. They can check the competitors rate to know if they are charging around that rate as well. They can as well put into consideration many efforts and time before you decide on what to charge your clients.
