Use free operating system instead of proprietary software, it has no licensing fee and get a life time support from the community. Imagine that you have 10 computers in the office and if you are using free software that’s a 10 times of saving.
In Proprietary software upgrade has always a cost and most of the time it’s new licensing fee so its another 10 times of savings if you are using a free software.
Use Libre Office, in a free software Office application is already included, while in proprietary software you need to buy it separately so it’s another cost for licensing, same with the upgrades or for a newer version.
Well known proprietary software has a lot of hole and viruses that cost not only in licensing but also for a lost of works and security. In free software like Gnu/Linux with a very small penetration of virus you can also download or get a free antivirus.
Get all the tools that you need for free, like Image editor Gimp, Music/Video Player and Html Editor, get everything at no cost and without hurting your business operation budget.
So instead of using pirated proprietary software why not using free or open source software?
