If it is PR mastery (not convinced) it's in the tone of the writing.

It reminds me of a notice of late payment I received from The Economist magazine some years back. It was so darn polite and diplomatic, I kept it in a shoebox ever since.

Now, whenever there's an outstanding payment issue with a client, I read the letter for inspiration.

I'd love to read that letter! Any chance you could scan it or type it up?

Hey, sorry it took me so long. HN was giving me a "you're submitting too fast" error for some unknown reason. Had to open up another account.

Anyway, here`s the link: http://www.picamatic.com/view/8244745_economist-invoice/
