Free version feature

I wanted to try Scanventory before buying it. Unfortunately it doesn’t work for me. All QR codes which I generated contains empty url (http://) so I cannot try mobile inventory management.

There is a note on Labels tab: ‘* Creating Temporary Labels Read More’ but http://scanventory.net/demo page is not found, I get 404 error. Is it a feature of the free version to generate empty urls or a bug?

How can I check if your mobile inventory management features are enough for my business?
