The Autodesk Fusion group buy package on JoinBareng is currently available as a 1 user private slot. That means you get one Fusion account used entirely by yourself, but paid through the group buy flow at a lower cost than a personal license purchased directly from abroad. The access type is credential, meaning a shared account login following the package rules, so the experience is similar to owning your own Fusion account.
Because the sharing type is credential, there are usage rules that must be followed so that all slots in the group stay usable. Do not change the account password, do not change the primary email, and do not log out other devices that are using your slot. If these rules are broken, your slot access is usually suspended by admin until the account is restored, so follow the rules from the start to avoid being interrupted in the middle of a project.
The multi-slot group package, which allows more than one user to share a single account, is still being prepared and will be opened later. Once the group package is available, you can order it from the same product page and invite other group members through JoinBareng. For now, the available and ready to activate package is the 1 user package with a monthly period.
Until the group package opens, you can still order the 1 user package anytime. The group buy price per package is shown automatically on the package card on the product page, so no manual calculation is needed. Once payment is confirmed, the JoinBareng admin will process the activation and send the credential access to your WhatsApp based on the standard processing estimate.
