A variety of approaches are often taken in upstream mergers.
One approach is to transfer all of the assets and liabilities to the other firm and receive a credit to your capital accounts for the value of the contributed assets/liabilities with a check from the other firm if the value of the assets contributed exceed the required capital contribution based upon the ownership shares that you are being offered in the merged firm.
The more common approach that I see taken in upstream mergers is for the smaller firm to retain the firm cash accounts, accounts receivable, work in process, and sell the fixed assets (furniture and equipment) to the other firm for cash or receive a capital account credit for the value of the fixed assets contributed. If additional capital is required, each partner would write a check to the merged firm for their capital contributions. Your existing firm would be responsible billing out old work in process and collecting old receivables and when the income is received these funds would be deposited in your existing bank accounts and entered in your old books. You firm would also be responsible for accounts payable and other liabilities that exit prior to the merger.
