One software license is required per user.
Available in both 'Standard Editions' and 'Suite Editions', Enterprise Architect is ideal for a wide range of projects, team sizes and target platforms.

Standard Editions:

• Corporate - Supports large, collaborating teams with security and remote DBMS access.
• Professional - Full featured UML modeling for workgroups, analysts and developers.
• Desktop - Comprehensive UML modeling tool for individual analysts.

Suite Editions:

• Ultimate - The complete Enterprise Architect experience across multiple domains.
• Systems Engineering - For systems engineering, real-time and embedded development.
• Business and Software Engineering - For business modeling, architecture, development and more.

Floating License Products
Enterprise Architect's Corporate and extended suite editions, as well as add-in products developed by Sparx Systems, can be purchased as floating licenses. Floating licenses are suitable for companies who wish to automate the management of Enterprise Architect registration keys, because they can be administered in a single, centralized repository. Sparx Systems Keystore Service provides the repository and administrative software to manage floating licenses.
The floating licenses service also supports off-site usage by allocating a key for a fixed period defined by an administrator.

You will need a floating license for each concurrent user.
For example if you have a team of 10 users but only require 5 users to use Enterprise Architect at any one time then you would need to purchase 5 Floating Licenses.

Subscription gives you access to free Enterprise Architect software updates for a period of 12 months.
