I've been asked if I'd be interested in running payroll for a small company, with 10 employees. Paid weekly. I can use the payroll system I use for the company I work for to do this. The new company has asked me to quote them a figure for dealing with the payroll for the year, including P35, P45's, p30's, the issue of payslips every week etc. Anyone advise?
Just to clear this up, it is not a 'nixer'. My current boss is also a director in this new company, and he has asked me to do it. So yes, he is aware that I will be using the equipment. I have no idea what to charge them for it, as I would most likely be billing them at the end of 6 months, and it would not be an hourly rate as such but more a fixed sum.
If your boss is the director of both companies, then it really does not matter how much you charge (within reason), as one of his companies is buying services from another of his companies. One company could be used as a cost centre and the other a profit centre. Of course, it is a different matter if he / she is a minor owner / share holder in the company purchasing the service.
Cross charging between companies is very common. Company A pays tax on the sale of the service, while company B claims the charge as a business expense.
