Hi All. How do you know if a NS managed bundle is paid or free of charge?

Your NetSuite account manager can tell you. Depending on the bundle and what you are already paying for, it may be included.

This isn't 100% by any means, but a lot of times you won't be able to see bundles in the search if it's paid until you pay.

Sorry another question. If you install that paid bundle in sandbox (not yet in prod), does the account get charged for that?

I'm not sure. Probably depends on the bundle

subscription starts immediately after contract signing. It doesn't matter if you install related bundle it or not.
