Test for Browser Compatability

The box above indicates whether RED Calc Pro will run properly in the browser you are using now. 

Individual Subscription Plan
You may subscribe to RED Calc Pro as an individual or as a team. The Individual subscription plans are renewed automatically, either on a monthly or yearly basis, until you stop your subscription. Each Individual plan includes a free, two-week test period. You may cancel your subscription during this test period before your credit card is changed.

Team Subscription Plan
Team subscription plans are a great choice for organizations, either WAP agencies or private organizations. As with Individual plans, they may be purchased on a monthly or yearly basis and are renewed automatically until the subscription is stopped. A Team must include two or more subscribed seats. If an individual occupying a seat is transferred to another department,  her seat can be assigned to someone else. This transfer cannot be done with an Individual subscription; this is one of a number of advantages of Team subscriptions. Each team must have an owner/manager (the person paying for the seats), who may or may not occupy one of the seats. The number of seats in a Team can vary over time, for example, additional seats can be added as an organization grows (if seats are added by the owner/manager, these new seats must be based on the same subscription period as the existing seats, either monthly or yearly). If the number of seats is reduced, the eliminated seats will remain active until the subscription period expires, based on month or year.
