accounting system compatability

Hi

I use an accounting system called xero.

What is the best report to import into my accounting system given the following?
I have looked at payment list. This includes prepayments or overpayments made on the day for clients that may have bought treatment packages – this is essential to show as the money was paid that day. Other payment reports do not show pre or overpayments ( so the total amount paid for the day is actually not included here, but they are excellent in that they detail the services claimed ( I need this as in australia massage incurs tax which has to be declared and physio does not).
As I am based in australia, on a given day a patient will pay for their treatment and will also claim a rebate from a health cover company (hicaps)- at present I enter this as a negative amount to the invoice. On all the payment reports this is listed except for the payment list!
Is it possible to have a payment report that is the best of both worlds, that is, will show over and prepayemtns made on a day and also show the negative hicaps taken for the day as well as the details fo teh services/and or product charged on the day?
thanks for your help
Kirsty
