Businesses that use EDI software and systems follow certain protocols for exchanging data electronically. Each transacting party is categorized as a trading partner and exchange mutual agreements that define a commercial transaction.

All subsequent transactions are then communicated in a standardized manner through an intermediate channel company called a Value Added Network (VAN) or via FTP with PGP encryption. The VAN is a third-party service provider that permits different trading partners to communicate through a central clearinghouse.

Please allow approximately 3-5 days for this process.

Step 1: Complete and return an EDI Billing Customer Agreement available through your account manager or the billing department. If you are a third party billing aggregator, complete and return a Third Party Agreement.

Step 2: Once the necessary agreement(s) are received, the EDI billing department will contact you to explain the electronic testing requirements and schedule a date for testing to begin.

Step 3: We will transmit a set of test invoices specifically used for EDI certification to ensure a successful download of invoices into your financial processing system.

Step 4: Once testing is complete, your account will be switched to EDI and you will no longer receive paper bills. The EDI billing department will notify you when the first EDI invoice is initiated.
