Inventory Express is free to use for a 30-Day trial period. When the trial period expires, you will still be able to view your collection, but you will no longer be able to add or update any items until you purchase a license.
A regular license enables all features except Online Collection Hosting and Personal Online Store, which require a modest annual subscription fee.
The email address with which you register Inventory Express is a part of your registration. Even if your email address changes, this field must contain the address with which you originally registered Inventory Express.
