Which step in monthly closing process the accountant should take care so he will know that he is on the correct track to finish it successfully?

Actually i didn't get the question well , but i can tell you my process

first of all i do make a P&L analysis so i can determine which expenses and rev are not recorded then i do my accruals or any unrecorded amortization / depreciation/payroll entry ... etc

after that i get the trial and start balance sheet accounts analysis for each account and reconcile each balance with the analysis and if there is any wrong recording i do my adjusting then i do prepare the financials 

this is a very simple overview of my way , if i didn't guide you to what you are asking for please tell me in a different way so i can help as much as i can

thanks 

maybe the answer will be the analysis for both the income statement and balance sheet accounts
