We have developed a product that is being used by a specific industry users. This product currently has 100 users and we are still in alpha.
We have interest from a organization which has 100 users. We are happy to provide the product for free until we are happy with the stability of our product.
So my question is should we get an agreement to charge them after say 6 months at $x ? We do not want to engage in a deceptive behaviour by getting them to use the product and then starting to charge them 6 months down the line.
