Is it a must to tell your clients before you raise your charge?

[Btaliat]

There are some instances where you need to increase you your charges. During this, there are more than enough reasons why freelancers need to tell the clients, especially those that have been there for long and always consistent. Doing this will prepare them against the raise. At least you can tell them like 30 days before the raise is done. What do you think about this?
