Delivered as a file, or over EDI or the API
A finished order can reach you by email as a PDF, a spreadsheet or a document, or travel by EDI, through the API or into QuickBooks. An emailed order needs nothing set up in X3; which other format suits your setup is a question for the demo.
Sent to a rep, a shared inbox or the order desk
Over EDI or the API, when your setup takes it, nobody retypes it
Credit checks, allocation and shipping still run in X3
Your phone line keeps working for accounts that prefer it
