Do you have a Shopify Lite store?

Manual orders allow you to send us an order that wasn't placed by the customer directly, such as orders from 3rd party marketplaces (e.g. Ebay). It's also useful if you have a Shopify store but need to place an order without the customer checking out.

You'll need a Shopify store with at least the Lite plan to place a manual order for a customer.
