My Suggestion is what I practice now Prevention is the key: It's better to prevent something from happening, than having to fix it once it has already happened.  And what I ​mean by this is once people have already received your product or service, and haven't paid you for that product or service; 9 times out of 10, you will probably never get the payment for it.  So this is why I ​always charge for my service upfront & collect before the service is given; that way I don't have to deal with chasing dishonest people to get my money.
