My client purchased HubSpot under a different domain than the domain that I registered -- can I still receive commission?

No. Commission is entirely dependent on registering the domain under which a client purchases HubSpot. Many companies have multiple websites or redirects so it is critical that you work with your customer to ensure that they purchase under the domain that you registered. There are no exceptions here, but we are always happy to work with you during the sales process to avoid this situation.
