Call me an ambulance

I followed advice in the Freelance and added a sentence to the end of my invoices, warning clients that late payers will be dealt with according to the new laws.

Today, for the first time since Creationists stalked the earth, I received payment on the date due, from a client who always paid late. It's utterly astounding what a few legalistic words can achieve.
