How do YOU usually deal with a non-paying client?

Do you really want to be know as the guy that sues his clients?

Don't blame the client. You made it easy for him by uploading everything
up on his site first then asking for the balance.

Now there are companies that will collect your invoice for fee, which i think
is 10% of the outstanding balance.

Just Google it to find one in your local area.

This is why I always keep a cpanel login/password in tact for their website. If they don't pay me, I start hitting the delete button.
