If you use Lolly Law to track matter billing and to print invoices, you may also need to print a payment receipt for clients.

To print a receipt, simply open the matter in Lolly Law and go to the Time & Expense section.  Under "Payments" you can enter a new payment or print a receipt for an existing payment.  Right click on a payment record and choose "Print Receipt".  You can also print a receipt while in the edit view of a payment.
