ProTrak is free, and the Pro version has a monthly subscription.

Everyone starts with ProTrak free and has the option to subscribe to Pro.

On the free version you will be able to access Clients, Proposals and Invoices. There is no limit as to how many Clients, Proposals or Invoices you can have.

On the paid, Pro version of ProTrak you will be able to access everything you had access to on the free version, plus Projects and Team. Project allows you to transform Proposals into a full fledged Project and track all its progress. 

ProTrak Pro costs $120 per month with a yearly commitment, or $150 per month if paying as you go.
