## TL;DR

An agent with cross-entity access can post to the wrong books, so scope every action to an entity: intake tags the entity from the invoice, matching uses that entity's POs and vendors, and posting targets that entity's ledger. Cross-entity invoices get explicit allocation, never silent defaulting.

## Steps

1. Determine the entity from the invoice (bill-to, subsidiary).
   Expected: An explicit entity tag.
2. Scope all lookups (POs, vendors) to that entity.
   Expected: Correct master data.
3. Post to the entity's ledger.
   Expected: Correct books.
4. Handle cross-entity via explicit allocation.
   Expected: No silent defaulting.
5. Audit entity attribution regularly.
   Expected: Mis-scoping caught.

## When to use

- Multi-entity AP
- Shared service centers
- OneWorld/company-code environments

## When not to use

- Single-entity operations
- Intercompany billing design
- Consolidation

## Compatibility

NetSuite OneWorld, SAP company codes, multi-entity ERPs.

## Variant phrasings

### subsidiary scoping invoice agent

### multi-entity AP automation

### entity tagging invoices

## Root cause

Entity boundaries are legal and accounting boundaries. An agent that ignores them creates misstatements that are hard to unwind.

## Edge cases

- Bill-to addresses can be ambiguous; confirm with vendor master
- Intercompany invoices need both sides' entities
- New entities need scoping configuration before go-live
