I run a payroll service for a number of clients. I calculate payroll and advise them what to pay their employees and HMRC. One client is a social club that requires 3 signatures on all cheques. They cannot use online banking. They have asked if they can send me a cheque for the money due to HMRC so I can bank the cheque then make the payment when the cheque has cleared.
How do I acount for this as it is not turnover as such?
