Retailer EDI requirements
Walgreens EDI requirements
ANSI X12 4010 · AS2/VAN/FTP · Portal: SupplierNet · Typical onboarding: 2–6 weeks
Walgreens-specific compliance context
- SupplierNet is the vendor portal for certification and day-to-day compliance visibility.
- Typical onboarding window: 2–6 weeks before production cutover (partner-controlled).
- High chargeback exposure when ASN, invoice, or label rules drift.
Core EDI documents
| Code | Document | Direction | Notes |
|---|---|---|---|
| 850 | Purchase Order | Inbound | Foundation of all Walgreens transactions |
| 856 | Advance Ship Notice | Outbound | Must arrive 4 hrs before DC delivery, 1 hr before store delivery |
| 810 | Invoice | Outbound | One PO per invoice; separate invoices for charges/credits; >90 days = $200 fee |
| 820 | Remittance Advice | Inbound | Received from Walgreens for payment |
| 997 | Functional Acknowledgment | Both | Notify Walgreens if 997 not received within 3 business days |
Compliance requirements

- Separate invoices for charges and credits — no combined documents
- One PO per invoice rule strictly enforced
- Testing required: 20+ invoices and credits before go-live
- Invoices older than 90 days incur $200 fee; >48 hrs risk rejection
Supplier programs & chargeback risk
Programs: Direct Store Suppliers, DC Suppliers, DSD
Chargeback exposure: High — late/missing ASN, late invoices ($200 fee), missing 997, invoice/PO mismatch
Penalty amounts, fees, endpoints, and onboarding windows reflect each retailer's published routing guides and public sources and change frequently. Confirm current figures in the retailer's own vendor portal before relying on them.
