The True Cost of Per-Document EDI Fees (And What to Do About It)

Legacy EDI providers charge by the document — or in some cases, by the kilocharacter (per 1,000 characters of data transmitted). This sounds negligible until you do the math. A typical Walmart order cycle generates: 1 PO received (850), 1 PO Acknowledgment sent (855), 1 ASN sent (856), 1 Invoice sent (810), plus 4 functional acknowledgments (997). That's 8 documents per order. At $0.25 per document, 100 orders per month = $200 in EDI fees on top of your base subscription. During Q4 when orders triple, you're paying $600+ extra — precisely when margins matter most. EDIPlug's flat monthly fee doesn't change based on order volume. Ship 1,000 orders or 10,000 — your EDI bill stays the same.
