Retail is busy onboarding new partners constantly. However, it takes so long they will never finish AND only the largest are allowed to participate.
Many demand Partners do EDI as they wish. Industries should collaborate within EDI standards to deploy following industry guidelines. Otherwise, custom onboarding will take too long.
Only the very large and courageous attempt EDI outside their industry.
Retail is currently devouring themselves with chargebacks. Huge mistake the market will correct viciously someday.
