I just tried to create a company named 'Test Company' and got validation error. I changed to 'Real Company' and got through validation. That's just silly logic.

I just tried to create a company named 'Test Company' and got validation error. I changed to 'Real Company' and got through validation. That's just silly logic. What other special validation will trip me up? What if my company name is really 'Test Company'? How do I receive a payment against an invoice?
