Welcome and thanks for joining the Community, @billy4.
I'm here to share some insights about removing a client's company file from your Wholesale Billing subscription.
Technically, when removing a client's company from your Wholesale Billing, their QuickBooks Online (QBO) subscription will return to the standard rate. Since there isn't a direct way to remove them without transferring the billing, you can inform them to cancel their account after.
To remove them, here's how:
1. Go to the Gear icon, then pick Your Account under Your Company column.
2. Locate the company you wish to remove, then select Transfer billing to client on the Actions drop-down.
Once done, you can provide this article to your client for the detailed steps on how to cancel their subscription: Cancel your QuickBooks Online subscription or trial.
For future reference, you can also check out these articles for more information:
