It's generally not a wise to guess about what I'm thinking. Inasmuch as it's
against federal law to send invoices by Standard Mail (look at your
telephone bill's envelope), one would think a similar rationale would apply
to other financial instruments.

And presumably one would be wrong for assuming that, since its
being done. Of course, you could point this out to Parago and
see if they are willing to change their practice.

And invoices are much different than checks, in that invoices
need to be delivered promptly so the recipient has ample time to
pay it.
