I worked in IT and due to company closure have become unemployed, I have been offered a job by a company but they want me for the first 3 months to stay off the books as they would be eligable for employment grant aid from the end of january and would hire me offically then. They have told me they want me to invoice them twice a month for my wages as services renendered to them and they would pay and then I would sort out by PSRI or PAYE or whatever was needed. What would I need to do here ? Sole trader? or is there a need to?
