Billable is an application for Mac OS X that helps you keep track of the billable services you perform for a client and then lets you create and manage invoices based on those services. Features: • Keep track of clients with a simple Client Editor. • Store per-client specific hourly rate defaults. • Import Clients from your Address Book. • Create Time-based Services with a time span and hourly rate; have Billable calculate the total cost for you. • Use the built in timer to start and stop a service. • View time progress of an active service via the badged dock icon. • Create Flat Fee Services and specify a manual total cost. • Select services you want to get paid for and create invoices with a single click. • Edit invoice attributes, including: Due Date, Partial Payments, Optional Messages, etc. • Customize the HTML template used to generate the PDF invoices and make the invoices appear how you want them to appear. • Use the source list to get a quick overview of unpaid invoices, services that have not been invoiced; filter down through the client hierarchy and limit the selection to a given client. • Export your data into XML. • Take advantage of the in-application software to stay up-to-date with new releases.
