Start with the event that puts incoming invoices into the offshore bookkeeping queue. A useful definition names the source, covered period, entity, current state, and completion evidence. It should also distinguish receipt from completion. A document arriving in an inbox proves that the team received something; it does not prove that the record is complete, correctly identified, or ready for posting. Write the entry rule so a new preparer and an experienced reviewer would select the same population. Then define the exit rule around a reviewable result, not around moving a card to done.
Applied to incoming invoices, the team should record a stable identifier and preserve the source timestamp. The preparer should be able to explain what changed between intake and review without relying on personal memory. The client-side AP owner remains accountable for decisions outside documented processing authority. This keeps the handoff useful while avoiding a vague instruction to use judgment.
