How can I change a customer to a vendor?

Hi, @connie20. Thank you for joining the Community.

At this time, you won't be able to make a Customer a Vendor.

You can edit the customer by changing it to a different name and make it inactive {delete it}. For step by step instruction, customers have found it helpful to go to Make Customer Inactive {Delete}.

I can leave feedback to our Product Development Team, and you can as well. I am going to provide the link where you be shown how to Submit Feedback in QBO.

You can always visit our QuickBooks Blog to know when updates or new features come available or just news about QBO.

If you have any more questions or concerns, please don't hesitate to reach back out to me. Happy Friday!
