Any suggestions for a cheap QMS?

It is my responsibility to purchase required software and hardware resources for the company. Company's current requirement is a cloud based quality management system. I have experience in using paid versions of different quality management tools. But my boss asked me to find a cheap one. I have searched in Google but didn't find any freeware tools. Recently I found few reviews of a product called Unipoint quality management software . It seems good but not freeware. Any suggestions from industry experts?
