Can I do an Interim Invoice?

1. You may print an interim invoice mid-month; however, once the Invoice is created, you will not be able to reuse the same Invoice Number. In order to show additional transactions, you will need to generate a new Invoice that includes only the new transactions or you will need to void the first Invoice and regenerate it through the end of the month. 

If you just want to show the client what his numbers are mid-month, you can print the Invoice as a draft. This will not issue an actual Invoice Number, and it will not create anything in Matter Status or make entries to the GL

2. As long as the adjustments you made to the Client are within the date range for the Invoice, they should show on the bill.
