Late payments, a worrying trend

I am supposed to be on holiday - but it seems I can still get frustrated by what is happening at home from the other side of the World.

It seems that every single client I've had over the last 6 months has messed me about over payment. EVERY SINGLE ONE. My reserves have been eaten up in overdraft fees and I often wonder if stacking shelves in a supermarket would be a better option - I've done it before and it was mind numbing but at least I had a regular pay check.

A couple of days ago I found out that a new client I'd worked for on a massive project over Christmas - getting in extra childcare and working right over the Christmas break - has not only failed to pay me on time but, on querying when the payment would arrive, I was told that it wouldn't be until the beginning of March. In what other profession than those who are freelance would this delay be acceptable? Because I can only work part-time at the moment this amounted to a months work - so my mortgage and other payments are all affected. Am I just unlucky with clients or is this a general trend that us freelancers should be aware of?

The client I've been ranting about for several posts is still emailing me over 'where I am' with the project that I finished 3 weeks ago. As I've actually spoken to the person I know he has been getting my emails so I am now regarding them as humorous rather than irritating - but really if they can't be professional with their freelancers how are they with their clients?

Now to workout a months interest for my late payer ....
