How create orders from the back office with products or concepts that do not exist on the web?

[hombredeincognito]

We are looking for a plugin for our prestashop 1.7.

We need a plugin that allows us to create orders from the back office with products or concepts that do not exist on the web.

Could you tell us if there is a plugin that can do it?

Thanks a lot!
