Add-On Packages & Their Licenses

The official add-on packages add reports, business process management, and workflows in the Advanced Pack, and quotes, invoices, purchasing, and inventory in the Sales Pack, among other things. Project management and online appointment booking are further separate extensions. They do not qualify the AGPL core for additional categories. Not all official extensions are proprietary. For example, the project offers the Real Estate extension under AGPL-3.0.

For the add-on packages distributed under it, the Extension License Agreement grants a time-limited right to use them on one production instance and two non-public development, testing, or staging instances. Distribution, sublicensing, and hosting for third parties are prohibited. These restrictions do not apply to the CRM core, which is licensed separately under AGPL-3.0, or to extensions that are explicitly openly licensed.
