If this is your last bill or notice as stated. Just throw it in the waste basket. Thinking that at least this is the last time I will hear from those suckers. .

Back on subject I consider an invoice as generally a more detailed accounting of the transaction described than a general bill. Although they can be almost identical as well.

A statement perhaps more of a general overall computation of dealng with the enterprise.

I also have no issues with the prior descriptions. We kind of consider them all as somewhat interchangeable. At the same time many corrected invoices leave no money owing. Again though you could say the same thing in general about the other two.
