We have several members who use credit cards to pay invoices issued, rather than paying on-line with the registration.
It would be a huge benefit for us if, when they call in to pay their invoice, that we can record that payment. This call is often made by the finance department of the organization days or weeks after the event, when it is not practical to record a registration and payment.
We definitely vote to have this made an important feature, although for me the larger priority is making sure that we can add taxes to the registrations/memberships. Definitely #1 priority
