>I see what you're saying. This is a whole different way of looking at things. The way we do it now, invoices and statements are the same thing. Each month, the trips and payments for that month are gathered, stuck on an invoice/statement along with the past balances that are stored somewhere and manually updated each month. This is what gets sent to the customer.

Michelle,

You could think of the Trips as invoices. A customer would have multiple invoices in a month (trips) and you would summarize all the unpaid Invoices (trips) on the statement.
