Thanks for sharing some details.

I’m not clear on your statement re the firm’s own deposit as other current asset.  Pls explain (again). 

I have beven now using sales receipts for retainers and going back and cleaning up erroneous entries. 

This firm’s monthly invoices to clients are for fees and what they categorize as reimbursed expenses such as courier expenses, copying etc.  

When there’s a lump sum settlement they pay some to another vendor like BCBS, some to another law firm and some to their own firm. Are any of thers advanced costs?

In the past I’ve entered open invoices using 12/31 charging to opening balance equity. I’m not trying to bring all TB balances over. Just for the balance sheet. Therefore actual data will be for 1/1 forward and accrual not cash based. 

Historical data will will remain in the original company file. 

I appreciate all of your replies and assistance.
