Can I generate a real PDF invoice?

Yes — add a PDF-generation node before the email step for a formal attached document instead of a plain-text summary.

Does this connect to accounting software?

Not by default — wire in your accounting tool's API (QuickBooks, Xero, etc.) if you want the invoice created there too.
