Wow, so my old invoices were basically late payment invitations.

Totally agree with brian_hart, cash is king.

You're right, @mia102, it's crazy how much weight gets put on small mistakes. I got an email back once where the hiring manager just corrected my spelling of "their" and ignored all my questions. It felt like they were looking for a reason to say no. That focus on tiny flaws makes the whole process feel unfair, like you're set up to fail. Your point about a wrong number on a resume is so true, it can totally derail the talk.
