I work as a self-employed marketer on a part-time basis (and work pt also) and I am having a lot of trouble with one of my clients. He is refusing to pay an invoice and demanding to see invoices from my subcontractors before paying me. This relates to printing work I got done - on their written approval, which was received as agreed. I paid for the printing and invoiced him for same. I included a small mark-up for my time setting up the print etc. but the client is now insisting to see the invoices. I think I am right in saying he has no right to demand this when he agreed printing costs etc. with me upfront. This has all stemmed from me dropping him as a client as he just got too much to handle - since I suggested terminating the contract he has behaved in a bullying fashion and is with holding payment of £2k for the printing and other associated work. I have threatened small claims court and he replied that he will counter claim and demand to see the invoices anyway and that the court will not look favourably at me for not letting him see them. He is now refusing to answer any emails pertaining to the matter. Should I go ahead with a claim through the courts?
TIA
