If you are thinking of ordering a "minor update" (from 8.x), you might want to think about getting an Update Subscription instead. This provides you with updates (through version 9.0) as soon as they are available. Update Subscriptions also provide organizations with an efficient and economical way to budget update purchases.
If you are doing a full-version update (from 7.x or earlier), you can switch platforms from Windows to Mac or vice versa. We don't allow a platform switch on the minor version updates (from 8.x or later)—however, you can switch if you are ordering an Update Subscription.
If you do switch, please include a note about it in the order, as otherwise, we'll contact you to verify that you intended to choose a different platform.
There is no shipping charge for updating from version 8.0-8.2 to version 8.3.
Additional shipping charges do apply on all other update/upgrades shipped to Alaska, Hawaii, and any destinations outside the U.S., as indicated in the table below.
If you prefer to avoid shipping costs on software orders, we offer the option of purchasing the software only, with no printed copies of the manuals, with the software downloaded from our web site. PDF versions of the documentation are included with the downloaded software (and are on the install CD if you get a "boxed" product).
| Destination | Cost |
| U.S. (48 states) | None |
| AK, HI, Canada | $30 |
| All others | $55 |
Illinois residents must add 9.00% sales tax. We do not collect sales tax or VAT on any other orders shipped outside of Illinois, however, you may owe an import tax or VAT that will be collected by your customs authorities.
Please contact us at sales@estima.com for quotes on updating multiple copies, network or cluster licenses, or if you have any other questions.
