BOM Approved Vendor List (AVL) Checker
Audit a contract manufacturer’s quote against your approved parts and sourcing rules. Find unapproved substitutions, missing placements and supplier channel conflicts.
Audit an AVL BOM before releasing a purchase order
Compare the CM’s actual manufacturer, full orderable MPN and source channel with the engineering approval for that line. The checker also identifies missing reference designators, scope changes and DNP placements. When both sources include quantity, it checks board demand across split quote rows.
Send the CM a hold sheet with the source rows
Review up to five risk examples for free. The complete Excel audit shows the source rows behind each decision and includes a hold sheet where procurement can assign owners and request evidence before approving a change. Uploads are processed in memory.
Approved vendor list FAQ
How does an AVL fit into a BOM?
The bill of materials lists what goes into an assembly. An approved manufacturer list (AML) identifies qualified manufacturers and part numbers. The approved vendor list (AVL) also governs where the CM can buy those parts.
Can I use a company-wide approved parts list without quantities?
Yes. Select your IPN, reference designator or requested MPN and map the manufacturer and MPN fields. Quantity comparison runs when both sources have a Qty mapping.
How do I fill in the approved vendor list template?
Keep the headers on Master AVL and CM Quote. Replace the examples starting at row 2, using the How_To_Use sheet to select approval statuses, scope and sourcing policy. Upload the completed workbook here.
