We outsourced our payroll for a number of years - we have just set up Sage Cloud Payroll but our accountant (who looks after our payroll) has said the following;

"I set up Sage Cloud Payroll from week 18 with 8 employees including yourselves.

There seems to be a problem with transferring balances forward from the payroll system to the new system – it doesn’t pick up the correct details, notability the USC."

Any ideas what the issue is? He suggested waiting until the new year but I'm not sure why?!
