How to post deposits, outsourced payroll, accruals for fiscal year...

Hello, So the situation seems a bit complex and I am having a hard time figuring it out. Hopefully someone can help. The organization has had Sage for years but only entered invoices and paid through the system. At the fiscal year end the bookkeeper would enter all deposits, payroll etc to create trial balance for CPA. As of now all I have in 2018 fiscal year is pais invoices. What is the process to enter our outsourced payroll, adjust AP and payroll accruals ( if needed). I have already entered cash receipts. Any advise?

Thank you
