Late payment law works
I'd like to share how well the NUJ advice on late payment worked for me. I got fed up with one particular group who I work for paying me late quite regularly, invoices going missing and being paid for a more recent invoice before ones that are already overdue.
So I sent off invoices detailing late payment charges plus interest for invoices that date back to the beginning of March with a statement of all they owe me, which includes work done since then. And hey presto, less than a week later I found a bank transfer for the total amount including the charges in my account, as a special payment, not part of their usual BACS run. So it definitely speeded up the system for me.
