How do you get your money that's owed?

Here is what you do. Write a letter requesting payment. Put a deadline in the letter. Make it reasonable time frame. State in the letter you will take them to small claims court if you don't get payment. Send the letter registered mail. When they don't pay go to your local courts and file a small claims suit. They will be served, given a court date. Make sure when you go to court you take your evidence with you.
