BillingTracker Pro is time billing and invoicing software for service industry professionals such as lawyers, engineers, accountants, programmers and consultants. It allows hourly, project-rate, retainer, or even contingency billing, tracks outstanding client debts, has a built-in timer, and creates professional invoices to be printed or emailed. BillingTracker Pro also has basic inventory and parts management for users such as PC technicians who sell products along with their services.

BillingTracker includes several easy to use tools to help you manage your professional business and invoicing better. The built-in timer, for example, can rapidly switch between clients and projects. this lets you accurately record the small amounts of time that most of us end up working during the day - woring on one project when another client calls for a few minutes, then an associate walks into your office to discuss a different matter, then a meeting, etc.

BillingTracker also lets you export your data in many different ways. Not only can you export reports, but also pretty much any information that you see on any screen can be exported to standard file formats.
BillingTracker creates professional invoices automatically, based on the projects and hours that you have entered. Choose from different formats, what information you want to include, and then either print the invoices or save them to a file that you can email.
