This system is sufficient for firms with the most basic Billing needs as it allows creation of simple invoices based on Time and Expenses that were tracked as part of your daily routine. Time Matters allows you to create an unlimited number of clients, billing rates and billing items. Rates can be based on global rates (where all activities are billed on the same scale), by Contact, by Matter, by Staff Member, or by Activity or Task Codes.
