Frequently Asked Questions

Quick answers about VO licensing, payment and getting your team started.

What is the difference between the license options?

Flexible and Enterprise are VO’s standard organizational license options. Flexible licensing supports shared access with a defined number of concurrent users, while Enterprise licensing supports larger teams requiring multiple concurrent users and centralized administration.

A limited Individual License may be available to qualifying independent consultants and small organizations. Eligibility is reviewed based on organization size, intended use, and licensing requirements.

Who qualifies for an Individual License?

Individual licensing is considered for independent consultants and small organizations with limited licensing needs. Availability is assessed case by case. Contact our team with information about your organization, users, and intended applications.

Does the Individual License include both modeling engines?

The Individual License generally includes VO OTTHYMO. If your work also requires urban drainage or hydraulic modeling, tell us about your needs. Access to VO SWMM may be considered as part of your licensing arrangement.
