Does anyone on here have a sideline to their main contracting job? For example I've been asked to write some example test specs and a testing strategy for a client who I used to work for. Would you just invoice as normal and put this additional stuff through your Ltd Co? If this became a lucrative sideline with increased volumes does your accountant start charging more for the increased paperwork? Wondering if the likes of NW would?
Any advice appreciated.
