Fastenal EDI Requirements
Fastenal requires every supplier to be EDI-compliant before going live. This page summarizes the documents typically exchanged, the chargeback profile, and how APIWORX automates compliance end-to-end.
Yes. APIWORX connects Fastenal EDI to your ERP.
But exchanging the documents is only the beginning. Chargebacks come from the process around them — the ASN that goes out after the truck left, the invoice that does not match the PO, the acknowledgment nobody watched.
APIWORX automates the whole supplier process for Fastenal: purchase orders landing as orders in your ERP, inventory and acknowledgments going back, ASNs and labels produced from the actual shipment, invoices matched to the PO before they transmit, and exceptions surfaced to a person while there is still time to fix them.

Chargeback Risk: High
Fastenal actively enforces compliance with automated chargebacks. Common triggers include late or missing ASN (856), ASN/shipment mismatches, missing GS1-128 labels, invoices that don't match the PO, late acknowledgments, and routing non-compliance. Penalties typically range from $50–$500 per violation or 2–3% of invoice value.
