New employee, no P45 or previous payslip

Hi all,

Can someone please help me?! I'm going insane with this! I only have a small company, and have only had one employee up until now. I've tried to add a new employee, but he has no P45 as yet or previous payslip, as it was all online and he never bothered with it. My question is, how do I now proceed without any tax or pay information? He has been paid during this tax year by the previous employee, so QB will not let me run payroll until all the employee info is complete. Any ideas??

Thankyou in advance.
