Thanks John!

Your correct. The client tells me it's 1 to 1 but I've had to redo to much in the past to rely on that. I'll use the second table. Sometimes you just have hit me with a bat to see the light.

>Unless you can guarantee a 1-1 ratio of a payment to an invoice, it's better to have payment information in a separate table. Let me give you a scenario: Suppose you receive a partial payment for the invoice? And then, down the road, get another payment that pays the original invoice in full and pays part or all of another invoice?
