The EDI ROI Formula
Net annual saving = (cost today - cost left after automation) - yearly EDI fees. First-year ROI = (net saving - setup) / (yearly fees + setup). Cost today is labour to key orders, the errors that slip through, and retailer chargebacks.
Worked example: 50 retailer orders a day
Orders a year = 50 x 260 = 13,000Labour = 13,000 x 8 min / 60 x $25 = $43,333Errors = 13,000 x 3% x $150 = $58,500; chargebacks = $400 x 12 = $4,800Cost today = 43,333 + 58,500 + 4,800 = $106,633Left after automation = 43,333 x 10% + (58,500 + 4,800) x 5% = $7,498Net saving = 106,633 - 7,498 - ($600 x 12) = $91,935Payback = $2,000 / (91,935 / 12) = 0.3 months
With these placeholder costs, EDI pays back its setup in under a month. Put in your own quotes to check.
What to Include on Each Side
| Side | Include |
|---|---|
| Cost today | Keying time, order errors, compliance chargebacks, late-ASN fines |
| Cost after | Exception review time, errors that remain |
| EDI fees | Software or VAN subscription, per-document charges |
| Setup | Partner mapping, testing, onboarding |
Retailers set the rules, so chargebacks often move the numbers more than labour does. See which documents your retailers require in the retailer EDI compliance guides, check whether you are ready with the EDI readiness assessment, and validate a document in the EDI inspector. For orders that arrive by email and PDF as well, the order processing cost calculator adds multi-channel overhead.
