APM & 8.0 for invoices

[system]

We are considering purchasing APM. We would like to select a batch of
invoices from Vantage 8.00 and e-mail to our customers at the press of
a button.

Is there anyone doing this now—and how are you doing it? Does APM
really work well for this? Are there better solutions anyone is using
rather than APM?

Thanks a lot,

Dick
