One list for everyone you bill, split into Active, Inactive, and Overdue, with the outstanding balance right next to the name. No digging through invoices to find who owes what.
Your invoices, estimates and clients are served from the network location closest to you, not from one machine on the other side of the world. Moving between a list, a new invoice and a sent document happens in the time it takes to look at it.
