Accounting integration with MYOB

We use an accounting package called MYOB. We want to integrate our internal and public website with our accounts package as a lot of time is wasted creating invoices which could in essence be created automatically. We execute credit card transactions and would like the invoices to be created automatically. Help. ## Deliverables I have heard others talk about XML or something like that for the integration to take place. You guys probably know more than me.
