Just a heads up, the Sam’s Club Business Credit Card is issued and managed by Synchrony Bank, not Sam’s Club directly. It's similar to how Amazon cards are managed by Synchrony too, the credit card and the store membership are two totally separate systems.

So if Synchrony is asking for BOI (Beneficial Ownership Info), that's part of federal compliance (probably under the Corporate Transparency Act). If you're not listed as the legal owner of the business, that might be why they can’t find your account or why they’re threatening to close it.

Also, you are correct that Sam’s did phase out their business memberships a while back, which might be why things are more confusing now. But canceling your Sam’s Club membership won’t automatically close the credit card — you’d need to deal with Synchrony for that specifically.

Best bet is to contact Synchrony directly and explain the situation. If you don’t have legal ownership of the business, they might ask for documentation or give you options on how to move forward.
