It would be really nice if there was the possibility to integrate with ccinvoices. The reason for this is that we use ccinvoices for other purposes on our site - using Akeeba Subscriptions to manage subscriptions and memberships etc - and we would like to have one unified invoicing system.

It seems that it would be possible to look at the Akeeba Subs integration with ccinvoices and use that as a base from which to write an integration for other extensions.
