Stock Policy

We encourage our customers to purchase licenses in bulks so that they can enjoy a better volume purchase discount with better unit rate. You may have concerns as you may not use all purchased CALs at the time of license activation and lose of FREE support maintenance on those unused CALs.

Our stock policy is designed to address this concern. Instead of activating all CALs at the same time, CALs purchased can be put on stock for a maximum of 1 year. And the first year's free software maintenance & upgrade will only start upon licenses activation.

For example, if you purchased 50 CALs of AhsayOBM on April 30, you may choose to activate 30 CALs first and keep 20 CALs on stock. Until April 29 the year after, you can withdraw the 20 CALs on stock at any time and activate them on your existing or new license keys.

You will need to activate all CALs on stock on or before the stock expiration date. Otherwise, the CALs will be cancelled and removed from stock.
