Invoice vs bill, answered.
Why does this definition matter?
Without stable boundaries, teams compare incompatible periods, classify the same record differently, and automate decisions from misleading summaries.

Make the definition operational.
Connect it to authoritative records, ownership, evidence, limitations, and recovery.
