Business document and invoicing comparisons
Factual comparisons of commonly confused documents and invoicing workflows—what each does, where it fits and when it cannot replace the other.
These are not product rankings or reviews. Each comparison uses practical criteria: purpose, timing, calculation, record keeping and the action expected from the other party.

The short version
Before the work: estimate (a prediction), quote (a commitment), purchase order (the buyer ordering). During or after: invoice (asking for payment), receipt (confirming payment arrived), credit note (cancelling part or all of an invoice).
