What the 812 is
The EDI 812 — the X12 Credit / Debit Adjustment — is formal adjustments — chargebacks, returns, allowances. It travels in both directions for most trading programs.
When it's sent
The 812 ends the cycle: settlement and adjustments that follow the 810 invoice.
Key segments
The 812 follows the standard X12 segment layout for its functional group. Partner companion guides add the specifics — EDISQ's certified maps carry those rules per partner, so you never read the implementation guide yourself.
