When accounting using the accrual method, you need to keep track of accounts receivable. The accounts receivable is the amount customers owe you in the future. Most accountants like to label each accounts receivable transaction. For example, if you have a miscellaneous transaction during the year where a customer did not pay yet, then you would label the account "Accounts Receivable -- Miscellaneous." This allows you to better track who has and has not yet paid you.
Determine the amount of the miscellaneous sale. For example, assume you sell $100 worth of miscellaneous parts you had on hand.
Debt "Accounts Receivable -- Miscellaneous" by the amount of the sale. In the example, debit "Accounts Receivable -- Miscellaneous" by $100.
Credit "Sales" by the amount of the sale. In the example, credit "Sales" by $100.
Debit "Cash" and credit "Accounts Receivable -- Miscellaneous" each time you receive any cash from the sale until the "Accounts Receivable -- Miscellaneous" account reaches $0.
