Is there another way to submit my invoices electronically?

EDI invoicing is always an option. This website's online invoicing tool will be restored the moment the site is returned to service.

I submitted an invoice/change right before the website went down. Do I need to do it again?

No. All previously submitted items were received and will be processed.
