I work as a freelance developer. I'm starting to win some high-profile contracts now, but I'm a developer first, businessman second. I've been reading about invoicing etiquette - what to include and how to word things.
I can't find anything quite as in-depth about purchase orders. Having received a polite email with the purchase order, should I confirm receipt, and say thank you? Is that "showing weakness"?
I've read some articles this morning that saying thank you for business is a bad idea, since it weakens my position (srsly?). What's the professional, but polite course of action?
