Accounts Payable is an integral part of accounting and of the monthly and yearly profit and loss reports. Payments may be deferred to future dates. Aging cycles track payments 30, 60 and 90 days past due. Late payment penalties and early payment discounts may be programmed into each account. Posting payment to credit card accounts receivable will automatically generate a surcharge payment to an account payable of the same name. Travel agent accounts can be set up so that commissions based on room rent are automatically posted as due to the appropriate account during the room check-out section of the night audit.
