Our TeamRaiser sponsors would like to be able to pay for their sponsorships online with a credit card. There currently isn't an out-of-the-box option to handle these. We can have them make an event-credited donation online using the existing TeamRaiser-associated donation form, but then an admin has to change the transaction type to be recorded as a sponsorship post-process. Or we can develop a custom solution with data integration. But this really should be something provided on the product level - sponsorships are a key aspect to any successful TeamRaiser-based event.
