Not sure if this is the best board to post on but hopefully someone will have some advice.
Quite a new client I completed some work for an the last invoice was 3 days late, chased it up and paid next day so 4 days total, annoying but ok.
Now they owe me another outstanding invoice - 12 days late. I invoiced again at 7 days saying it is overdue. My contact in the company replied saying they will chase accounts (I have no details to contact accounts myself). I've heard nothing and no money in my account.
Now I am working on a big batch of work for them, I have a 14 day turnaround agreement and the work is due tomorrow, it's worth £1,000.
Not sure what to do, they owe me £250 on the overdue invoice plus £600 on other invoice due early next week.
I'm so reluctant to send them more of my work when I am due payments but if I don't then I am breaching our agreement.
Anyone have any advice please?
