100% Unlimited Projects

No matter if you have 1 Project or 100 Projects, never worry about upgrading to add more. Go ahead and add as many projects that you need. When you're done, export a PDF Invoice and send it to your client.

Professional Project Tracking & Billing

Track everything that has been done on the project you're working on. Each project is broken into multiple parts for easier tracking and billing.

Flat Rates, Hourly Time, Project Expenses, and Payments


Under Flat Rate & Project Expenses you can add and Edit, project Dates. Give a complete Description of what was worked on or purchased. Enter the Billable Amount along with Tax, and the Tax Total and Project Total will be automatically added.


In the Hourly Rates tab you'll be able to activate the Timer to precision tracking and a new line item will be created with the total time. Add or edit your hourly rate, and have the Tax Total and Project Total automatically generated.
