Subscription Requirements for Custom zzTakeoff Scripts

I am currently working with a potential client who is using zzTakeoff, and I want to make them aware that there may be additional subscription costs if I develop a custom package for them using the Development area.

As an example, I have created a beta app where the user selects a roof plane and runs a script. The script allows them to select from pre-installed roofing profiles, then automatically draws over the measured area to generate a roofing sheet cut list, as shown below.

I know there has been discussion around introducing a new subscription model for more intensive scripts and custom development.

Could one of the developers please confirm whether something like this would fall within the new subscription bracket, and whether there would be any additional licensing or subscription costs for the client?
