Welcome aboard to the Community, userstacey-pearson71.
In QBO, you can easily merge customers, accounts, and vendors. For two QuickBooks accounts, you can consider using a third-party application to consolidate them.
We have an authorized app that can help sync the data files. Check out this guide to access the link for the third-party application: Can I merge multiple companies into one?
For future reference, I invite you to visit the QuickBooks Resource Center. It contains articles and tools to help efficiently manage your cash flow, taxes, payroll, etc.
Reach out to me if you have questions about the product. The Community has your back and I’m here to answer them for you. Have a great rest of the day.
