Can I split or share the cost of a Partner or Team license between myself and others?

Yes, by following these steps.

One of the persons amongst those of you splitting the cost of the licenses will first have to make the purchase from the store page of our website, with a credit card. The rest can then reimburse him/her, and having made the purchase, they'll be able to access the License Manager, whereby the option to transfer license codes to other email addresses is available.

You may find more details on how to transfer a license code here.
