How can i block orders from invoicing?

Summary:

We've imported Purchase Orders from last ERP of the client when we go-live.

Those Purchase Orders have already been Invoiced and Paid, But haven't received yet.

So we needed to import them as "Closed for Invoicing" Status. But appearnetly it wasn't enough and the POs were invoiced again by mistake.

We need to be able to prevent Invoice for Orders without close them. They still need to be Open for Receiving, as the goods haven't received yet.

Does anyone have a solution?
