External IDs help staff match a Plato order with a third-party order.

Use them for aggregator workflows where the customer or partner already has an order number.

## When Staff See The Prompt

If `Request External ID` is enabled, POS asks for the external ID when staff create an aggregator order.

Staff can enter the ID or skip it when the external reference is not available yet.

## Good Practice

Enter the external ID exactly as it appears on the source platform.

This helps the team answer customer questions and compare orders later.
