Sandcastle Products Ltd. is a new company setting up its administrative department to support operations. It has contacted Peter, who owns a local company called Easy Payroll (EP). Sandcastle Products does not have enough administrative work to support a full-time payroll clerk. EP's rate is very costly, but Peter can go to Sandcastle Product's office twice per month to complete payroll. This arrangement is only for the next six months and will be re-assessed at that time. How would payroll be classified in Sandcastle Products?
