Manage Customers and income

You'll have to add a character or symbol to one of the company names so you can record them both as your supplier and customer in QuickBooks Online (QBO), @Victor Chor. I'm here to guide you how.

When you record the same company name into your supplier and customer lists, QuickBooks will display an error that the info you entered already exists. To possibly record the same name on both lists, you can alter either your customer or supplier info by adding a character or symbol. 

You can first add a customer to the list. After that, go to the Expenses menu's Suppliers page to add a new supplier that includes a symbol. You can refer to the screenshots below for your reference.

Also, you're able to keep your accounts, customers, and suppliers organised in QBO. To do this, you can merge any duplicate data on your list. For the complete details and step-by-step guide, you can refer to this article: Merge duplicate accounts, customers, and suppliers in QuickBooks Online.

I'm also including this article to further guide you in managing your business's growth using QBO: QuickBooks Help Articles. It includes topics about customers and income, taxes, and banking, to name a few.
