Hi Alex. I have a similar question to the above. But the other

Hi Alex. I have a similar question to the above. But the other way around. We are an irish based company who provided design and coding service to a client in London. We received a deposit payment and the balance was due when the work was complete. On good faith we handed over all the code and designs so the client could test and also responded promptly with any outstanding issues they had. We asked them if there was anything else they needed us to address to which the answer was no. In turn we then invoiced them the balance and they put the website live shortly after. Two months on my accounts department have made numerous attempts to chase up payment as we still haven't been paid. We didn't get a single response to this. I then contacted the CEO directly who was also ignoring these statements and I requested payment. He then informed me that in fact they had issues with what we gave them that he wanted addressed and said they highlighted these issues already, which is definately not the case. I have asked for a copy of the mail he is referring to and have not received it. We are a small business and can't afford to take a loss of several thousand euros. The payment is already two months overdue and I know we are going to be fighting a losing battle to get our money. They currently have the site running with our design and code which they have not paid for in full and it is making them considerable money through advertising . Can you please advise how we could go about getting what's due to us or if we can even sue and claim interest and damages and if so how would we go about the process? Thanks for your time. W
