When you purchase an EEMS subscription license, you will have access to the entire EEMS modeling suite for the subscription period you have purchased. If you choose not to continue your EEMS subscription, you can still view any model built with your subscription by using our Demo Version of the software. However, without an EEMS subscription, you will not be able to edit your model or perform pre and post processing functions.
Customers who have previously purchased a perpetual license to EFDC_Explorer or CVLGrid will have no change in service or in maintenance cost. The pricing listed above applies to new purchases only.
Although we have priced our subscription packages to be the best value for our users, we know that perpetual licenses may still be required by some organizations. We offer EEMS in perpetual license format and these can be upgraded after a period of time. Please contact us to know the cost of your upgrade.
We do offer a 50% discount for universities if the license is used solely for educational purposes. If you believe you qualify for the discount, please fill out the EE Academic Use Agreement and email it to [email protected]. We can send you a one-time discount code to process your online order, or we will send you an invoice directly.
Currently we do not offer direct discounts for government agencies. However, by choosing our Business or Enterprise options, you can have access to many licenses to distribute across your organization. These packages have a significant discount applied to the cost per license.
We distribute EEMS electronically as a download from this site to the User’s registered email address. Once we receive payment, we will send you your license name, code, and installation instructions. You can then immediately begin using EEMS. Our support staff will assist you with any installation problems, if needed.
Since our software is delivered electronically, there are no shipping charges.
Depending on the customer’s location, a sales tax may be calculated and charged. Foreign buyers purchasing the software from a local reseller should be charged local sales tax. In the United States, only accounts in Washington State are subject to sales tax at this time. Any sales tax charged will be shown on your invoice.
If you purchase a license of EEMS and are not satisfied within the first 30 days, you are entitled to a refund. We have engineers and software support technicians that can help troubleshoot any issues you may be experiencing. We’d love to try to help you succeed before you return your license.
DSI currently has direct sales partners China, Korea, Malaysia and Vietnam. Visit our Sales Partner page to contact them directly. If you need to purchase through a local agent and are not in one of the countries listed above, please email us at [email protected], we can work with local agents on a case-by-case basis.
