What is the NI Volume License Manager (VLM) Overdraft and how does it work?


Overdraft is an agreement preference that allows you to use more licenses than your agreement with National Instruments (NI) specifies and pay for them later. Refer to your Volume License Agreement (VLA) for specific purchasing requirements and overdraft licensing options.

You can allow an overdraft of up to two times the number of licenses you purchased with NI. By default the option is disabled in VLM. When enabled the default overdraft is 50% extra of your current licenses. The assignment of permissions beyond agreement limits, along with the overdraft settings, is noted in the volume license agreement log that you send to NI at the end of the agreement period.

In VLM 3.1 or higher, you can enable overdraft by clicking on Tools in the Toolbar at the top of the software and then clicking preferences. This will open a new window where Overdraft can be selected in the left hand panel. Check the box Allow Overdraft and set the overdraft percentage that you would like. The overdraft applies to all products in your agreement license file, except those products that use concurrent licenses. You must accept the terms and conditions notification before overdraft can be enabled in NI VLM.

Additional Information

You have the option to check Enable pay-as-you-go if you want to enable pay-as-you-go. This setting reminds you to send your VLA Log to NI in order to cover the overdraft by purchasing the corresponding licenses.

Please Note:

  • You do not need to select pay-as-you-go in order to enable overdrafts. If you do not check pay-as-you-go, you will pay for the overdrafted licenses at your volume license agreement renewal.
  • If you enable pay-as-you-go, the license maintenance will be prorated when you pay for the license. If you do not enable pay-as-you-go, the license maintenance will not be prorated. For more information on renewing agreements, refer to Renewing Expired Agreements.
