If you wish to record Transactions against your Contract such as Invoices, the Transaction tab will allow you enter the relevant details.
If you have the Transaction Total and Remaining budget fields on your Contract form then any records entered here will be used to calculate that Total.
You can enter as many records as you wish, but to allow Totals to be displayed you must enter a value in either the net value or Gross Value and the Invoice Date or Paid Date field depending on what your account has been set to.
