The transformation

What changed in four weeks.

Before Commerce OS
  • SPS Commerce for Walmart EDI ($400+/month)
  • 820 remittance reconciliation in Excel (2–3 hrs/document)
  • FedEx labels from FedEx Ship Manager (manual)
  • QBO entries posted manually
  • Inventory desync between Walmart and Shopify
  • Customer service email backlog (no triage)
  • Retail deductions disputed manually or written off
After Commerce OS
  • Direct Walmart EDI via AS2 (no SPS Commerce fees)
  • 820 remittance auto-reconciled to QBO (exception queue only)
  • FedEx labels auto-generated on order receipt (Zebra printer, zero clicks)
  • QBO entries posted automatically at ≥ 95% confidence (Bookly)
  • Inventory synced across Walmart and Shopify on every order
  • Shopify chat agent live on americanwhistle.com (24/7)
  • ROS agent auto-files retail deductions

"We were spending two to three hours on every Walmart remittance document. Now it's done before I finish my coffee."
