Automatically forward files to a fixed email address

I want automate sending an email with an attachment / or as a minimum just the file (no email) to a fixed email address that does not use

Situation: Person A would fill in a form and submit a file (in this case an invoice), I would then get notified that a new item had been received (easy). I would then check the invoice and change the status, at which point I want to automatically send the file (invoice) to finance for payment. Our finance team are not using This is more about managing my workflow and budgets across multiple projects without having to download and save files is different locations and manually send emails etc…

Is this possible?
