Transmitting the Invoices to create a Vendor Bill in your Customers' account is done with a Map Reduce Script.
This is provided with the bundle, the name / ID is as follows:
eXtendNS2NS Send Invoice M/R / {customscript_extend_ns2ns_send_invoice_m}
You can schedule this for your requirements, and during testing you can trigger the "Execute Now" to validate transmission success.
