Installment payments for COM without IFM

To the list,

Does anyone have a procedure to process installment payments (like a deposit
on a custom order) and you do not have IFM? What steps do you do to show
the "receipt" of the down payment/deposit and how does it affect your GL
(when you post the cash to AMAR)? Do you debit the standard Cash Account
and credit AR or do you debit a "customer deposit" account and credit a
liability account like "customer installments payable"?



Thanks for any help.
