I’ll share the fact that Mac, iPhone, iPad, etc. purchased from Apple Business Store are not linked to ‘Apple Customer Number’ and cannot be managed in Apple Business Manager (ABM).

Background: Want to Purchase Refurbished Mac and Manage with ABM

I contacted the Apple business team to confirm whether I could purchase a refurbished Mac for testing and manage it with Apple Business Manager (ABM).

Conclusion: Even Purchasing from Business Store Doesn't Link 'Apple Customer Number'

Products purchased from Business Store - Business - Apple (Japan) (ビジネス向けストア - ビジネス - Apple (日本)) are not linked to ‘Apple Customer Number’ and therefore cannot be managed in ABM.

Solution: Purchase Through Apple Business Team with Corporate Contract

‘Apple Customer Number’ is only linked when purchasing through the Apple business team with a corporate contract, so this is the only solution.

• Order from and purchase through your Apple business team corporate representative
• Purchase through your company's custom online store

That’s all from the Gemba on learning that Mac, iPhone, and iPad purchased from the business store are not linked to ‘Apple Customer Number’.
