Documents
The EDI documents Fastenal trades with suppliers
Fastenal sends purchase orders; you send back an acknowledgment, a ship notice and an invoice, plus inventory advice and routing requests where Fastenal asks for them. Each outbound document is built from your ERP’s own records.
| Document | Direction | What it carries |
|---|---|---|
| 850 Purchase order | From Fastenal | Stocking and drop-ship orders, entered as sales orders in your ERP |
| 855 PO acknowledgment | To Fastenal | A status for every line: accepted, backordered, quantity or price changed, or rejected |
| 856 Advance ship notice | To Fastenal | GS1 SSCC carton IDs, carrier package numbers, the bill of lading and the quantity shipped on each line |
| 810 Invoice | To Fastenal | Built from your invoice, with payment terms and the remit-to party |
| 846 Inventory advice | To Fastenal | Stock levels for your items, read from your ERP |
| 753 Routing request | To Fastenal | Asks for routing on shipments where Fastenal chooses the carrier |
Our Fastenal maps send the order documents in X12 version 4010. Inbound X12 documents are acknowledged with a 997 as your partners require.
Fastenal specifics
What our Fastenal maps take care of
Carton-level ship notices
The 856 carries each carton’s GS1 SSCC ID and the carrier’s package number, with the quantity shipped on each line, read from your shipment.
Inventory advice
The 846 sends stock levels for your items from your ERP, so Fastenal sees what you can ship.
Routing requests
Where Fastenal arranges the freight, the 753 asks for routing before the shipment leaves.
Drop-ship orders
Orders that ship straight to Fastenal’s customer are covered. On Prophet 21, packing slips in Fastenal’s layout are generated from each pick ticket.
Onboarding
Getting live with Fastenal
A new Fastenal connection typically goes live in 4–8 weeks, paced by Fastenal’s testing.
Check your partner list
Run your partner list through the trading partner lookup, or send it to us. Fastenal is already in our map library, so setup starts from a proven map.
Exchange IDs and connect
You and Fastenal exchange EDI IDs and connection details. We set up the connection, whether AS2, SFTP or a VAN, including certificates.
Connect the map to your ERP
We tie the map to your ERP: items and the partner’s part numbers, ship-from locations, ship-tos and terms. You confirm the business rules.
Test with Fastenal
Test documents go to Fastenal until its testing signs off. This step sets the pace of the project.
Go live
Production orders start flowing, and our monitoring watches every document from the first day.
Managed EDI
How Comparatio runs Fastenal EDI for you
Our engineers build and change the maps, run the partner testing, maintain the connection and act on monitoring alerts. Your team keeps the ERP records current and makes the business calls.
Monitored by engineers
Daily checks, set up per partner, flag a document Fastenal never acknowledged or an invoice with no matching ship notice, and our team opens the ticket. In the 90 days to 28 Oct 2026, 61% of our tickets were opened by our own monitoring.
Same-day map changes
When Fastenal changes a requirement, we change the map the same day, with no project queue: map changes took a median of 103 minutes in the 90 days to 28 October 2026.
Checked before it goes
Every outbound X12 document is checked against Fastenal’s rules and reported, and can be held per partner.
Acknowledged as required
Inbound X12 documents are acknowledged with a 997 as your partners require. The 997s Fastenal sends back are matched to the documents they answer.
Connections and certificates
We set up and maintain the AS2, SFTP or VAN connection to Fastenal, including certificates and renewals.
Named engineers on every ticket
Questions go to engineers who know your setup, with a median first response of 79 minutes (Oct 2025–Oct 2026).
