Licensing is based upon the number of unique log-ons (seats) you require for administrative purposes. NOT your total administrative staff. NOT the number of members or contacts. Remember, over time your contacts will grow. It is not just members it's also attendees at meetings and anyone who interacts with you through the web site. Your contact data is an invaluable resource that you do not want to have to purge to control costs.
You may share a log-on within your staff.
Starting for as little as $99/month for one seat.
As the number of seats you require increases, the price per seat drops - dramatically. Five seats is $2,935/year. Beyond the first five, additional blocks of five seats are only $425/year per block.
