Some add-ons, such as Charts and Spreadsheet, require a commercial license. The license is required for doing development work with the libraries. Whether you sell the application or not doesn't matter, you need to buy the license in all cases. The licenses are not for applications, but for the developer (you) who uses the libraries during development. You can use a license to develop as many applications as you want. The licenses are personal (although transferable), so each developer need to have his or her own license.

That said, you can obtain free trial licenses with 30-day expiration to evaluate if the add-ons work for you.
