Steps

In PartsTech, open suppliers and Choose location for each warehouse you buy from (Worldpac, AutoZone, O’Reilly Auto Parts, NAPA Auto Parts, and the rest).
New Supplier rows that only show one store can be added with Add for that address.
In Tire Base, open Settings → Organization Settings → Integrations → PartsTech, pick the location, and click Sync Vendors.
Map each PartsTech supplier to a Books vendor (or Create vendor) so Order on the work order can post a purchase order.

Conclusion & best practices

Your list will not match another shop’s list exactly — PartsTech only shows warehouses that service that account. After mapping, shop from the POS PartsTech card so parts and cost come back on the ticket.
