Hi, @melissas-marines.

I can see the challenges of deleting and recreating invoices and payments to transfer your sub-customers to another parent customer. Let me share some insights on this.

To transfer a sub-customer to another parent account, all of its transactions must be under its own name. If any transactions, like payments, are associated with the parent account instead, the transfer cannot be completed because it would break the link between invoices and payments.

To answer your question, the only solution is to delete and recreate the payment transactions, assigning them to the sub-customer rather than the parent customer. This adjustment will allow you to successfully transfer the sub-customer to a different parent customer.

Once you have transferred the sub-customers, you'll want to keep track of their transactions by checking their balances. I recommend reading the article titled Print a customer or vendor register in QuickBooks Online. This will guide you through running balance reports to help you monitor the transactions effectively.

If you have any further questions about QuickBooks or anything else, please don't hesitate to ask. I'm here to assist you.
