Me: Right, I’ll send through your invoice now.
Client: Oh, don’t worry about that – I’ve already sent it. Check your email.
Confused, I check my inbox to find an email with a text document attached charging me £800 – the amount I quoted the client.
Me: I still I think I better send an official invoice to you…
Client: What are you talking about? Why would you possibly want to charge me? I’m the one that has put time and effort into managing this project plus I allowed you to design AND code it all – you should feel privileged!
Client: I expect payment within 30 working days.
