Framemaker subscription invoices

I am the IT responsible at our company and we have 2 Framemaker subscriptions that 2 of our users have and use. I have asked the support a couple of times if we can either pay per year or even better have the invoices emailed directly to our erp system.

The support could not help me with this and i cant describe the irritation of the users who have to be alert and forward the email every month so it gets paid and now during vacation time.........

How hard can it be to send an invoice for a year or change the invoice email address?

Very frustrated admin.
