Da Italiano a Inglese Affari/Finanza Contabilità/Amministrazione

I'm translating what I think is known as a debtors circularization - essentially a request sent out by a company to its customers asking them to confirm the balance of their account. At a certain point in the form that the customer is asked to complete and send back, the balance is broken down into “- da scheda contabile” and “- da conto effetti”. Underneath there is a “totale”, leading me to assume that the two figures are to be added together to produce a total balance. Would this make sense from an accounting point of view? And, assuming that it would, might possible translations be “accounts payable journal” (I presume we're talking about "conto effetti passivi") and “ledger card”?

Thanks in advance
