I have an invoice that has been unpaid for over a year now. I have sent them numerous messages, emails, LinkedIn messages and every time they claim they are about to pay, but they haven't. I would love to send them a legal letter or send a debt collection company after them, but they are based in the Middle East.
Can someone with experience of international due payments please advise me on how best to proceed?
Oh no - it will be very difficult indeed to get the money, that's why generally speaking you get a letter of credit in advance for international trade, or payment in advance. You might have to chalk this one up to experience I'm afraid
