I was reading the previous entry regarding pricing and rights, and then I remembered there was this article written by GoMediaZine some time ago. Took me a while to find it, here's the links:
GoMediaZine: A Designer’s Guide to Pricing
This article will cover:
What should I charge?
Flat rate or hourly billing?
How can I avoid being stiffed?
Should I have contracts?
Do I need an accountant?
What’s a “Kill Fee”?
How do I send invoices and track sales?
Another article I thought was pretty interesting is this one on design piracy
Some of it may not necessarily be relevant, but I find GoMediaZine has many good articles with insights and tips about how the industry works, as well as good tutorials/essays.
