Hello treasurer91!

Thanks for reaching out to us again. I understand that you need an option to add customers and vendors with the same name. Let me assist you with it.

QuickBooks Online won't allow us to add a customer, vendor, or employee using the same name. The reason behind this is to avoid confusion that may affect your entire accounting data. We always advise adding a special character or digit to fix this.

Also, I noticed that you mentioned Quicken in your post. I suggest you reach out to them to see if they have a resolution regarding the customers and vendors with the same name. Simply click this link: https://www.quicken.com/support.

Do you need help in running financial reports? Check this article: Run reports in QuickBooks Online. This includes links about customizing reports, memorizing, and other common reports.

Leave a comment below if you have other concerns. I'll be here!
