Voyager normally applies prepays to existing charges, even if the charge does not affect the G/L until a future date. If your workflow includes future charges, and you do not want prepays to be applied to those charges until the charges affect the G/L, activate the Prepay Future Charges optional parameter. With this parameter activated, you enter receipts normally, applying payments to open charges. Then, when you post the receipt batch, Voyager creates two receipts for a payment applied to future charges. The first receipt treats the payment as a prepay, and puts the funds in the prepay G/L accounts. The second receipt is a zero receipt that applies the prepay to the future charge on the date the charge affects the G/L.
