So if all of that hasn't worked - and you've reached the point where your invoice still isn't being paid, perhaps your client is not responding to your emails, or simply you were relying upon a payment to come in on time to pay the bills, how do you deal with the impact of late payments?
There are three types of impact: emotional (how it makes you feel), professional (how it affects your business) and financial (how it affects your ability to stay afloat). In reality, they're intertwined - and not getting paid has a knock-on effect to the rest of your work.
