Start with the distinction.
Receiving instructions describe a proposed destination. They do not, by themselves, establish identity, representative authority, the amount to be paid, or permission for the office to release it.
Keep the basis close.
The current instruction, the supporting material, and the office’s open questions belong together. An attachment arriving is an event; its adequacy for a particular review is a separate judgment.
Make the participant’s act clear.
A seller supplies the requested contribution. Their submission should not be described as an office approval or confirmation that money moved.
Leave a usable handoff.
The result should identify what the office considered, the act it made, and what remains under its own procedure or with its bank. The receiving-review service ends at the agreed boundary.
A product and workflow explanation, not a substitute for the office’s procedure or professional advice. The examples on this site are fictional.
