The cloud version of Hannah's Shop has the same functionality as the trial version but it has a 5 minute run-time limit.
The trial version allows you to compare the results from using Min-Max and EOQ inventory management rules in a perfect world environment.
(Perfect World is where there is no variation in demand or supply).
If you purchase a license to activate your product, you will will be able to compare the results of not only Min-Max and EOQ in real world scenarios but also see how much better the results is when using DDMRP Dynamic Buffer Management rules.
(Real World is where there is variation in both demand and supply)
