OTM calculates the shipment cost and creates an original invoice. The carrier logs into the SERVPROV domain to approve the original invoice. Multiple validations occur in the background and if the original cost hasn't been modified, OTM approves the invoice for us, otherwise people are alerted and statuses flip.

The original invoice must be approved by the carrier before he gets access to add subsequent charges on a shipment. The carrier will add costs to a shipment and create a subsequent invoice. All subsequent invoices must be manually approved by us. In order to get a separate invoice for subsequent charges, you need to set the planning parameter CREATE NEW INVOICE FOR STANDARD APPROVED ADJUST to TRUE. Otherwise, you'll see the subsequent charges as additional line items on the original invoice.

So we have a two-step approval for every invoice, one by the carrier and one by us. Depending on various validations, we may automatically approve the invoice for either the carrier or for ourselves.
