Learn more about how OCS Inventory is licensed and how this affects you.

OCS Inventory is released under the GNU General Public License, version 2.0 (GNU GPLv2). The GNU GPL provides for a person or persons to distribute OCS Inventory for a fee, but not actually charging for the software itself, because OCS Inventory is free.

OCS Inventory is free to share and change, but if you do change it in anyway, can you also change the license and make it commercial? No! The whole GPL is devoted to ensuring this does not happen. Copyright, a much more refined and stringent law will prevent this as well.

So with regard to OCS Inventory, the GPL and copyright:

You MAY distribute it and charge for that service. You MAY change it, add design and content to it and you MAY charge for that. You may NOT alter the license and you must NOT alter the copyright.

In other words, you must NOT pretend that OCS Inventory is yours, and you must NOT charge people for OCS Inventory.
Use OCS Inventory to empower yourself and your clients. Charge for the value you add and not for the hard work that OCS Inventory Development Team and the OCS Inventory community have put into it.


OCS Inventory is "free" software released under the GNU General Public License, version 2.0 (GNU GPLv2).

The word "free" has two legitimate general meanings; it can refer either to freedom or to price. When we speak of "free software", we're talking about freedom, not price. (Think of "free speech", not "free beer".)

Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software:

  • The freedom to run the program, for any purpose.
  • The freedom to study how the program works, and adapt it to your needs (Access to the source code is a precondition for this.)
  • The freedom to redistribute copies so you can help your neighbour.
  • The freedom to improve the program, and release your improvements to the public, so that the whole community benefits. (Access to the source code is a precondition for this)


  1. Who owns the copyright to OCS Inventory? The copyright to OCS Inventory is held by OCS Inventory Development Team.
  2. Are there any restrictions to your use of OCS Inventory? The GNU GPL grants you the freedom to use the software for whatever purpose you see fit.
  3. May I charge money for OCS Inventory? The GPL allows everyone the freedom to do this. The right to charge money to distribute OCS Inventory is part of the definition of "free" software.When people think of "selling software", they usually imagine doing it the way most companies do it: making the software proprietary rather than free. So to avoid ambiguity you may charge to distribute the software and any other service you provide along the way. You may not charge for the software itself.Remember if someone pays your fee the GPL also gives him or her the freedom to pass on the software with or without a fee.
  4. May I remove the "copyright" statements from the source code to OCS Inventory? No, you must keep all copyright notices and credits in the source code.
  5. I have modified OCS Inventory for my own use. Do I have to release these modifications? The GPL permits anyone to make a modified version for their own use without the requirement to distribute it or pass on those changes to others.
  6. I have made a modification to the OCS Inventory core code. Do I have to release it under the GPL? If you chose to distribute your modifications to others it must be released under the same terms that you received the original code. So your modifications must be released under the GPL. You may of course in this case modify the headers for the source code to include your own copyright statement. If you do so you must clearly annotate in the source code your amendments, changes or additions.
  7. I have written an extension or additional module for OCS Inventory. Do I have to release it under the GPL? No. The GPL allows you to write your own extensions for OCS Inventory and to release those extensions under whatever license you chose.
