When my data was converted to QBO, two of my employees were classified as vendors and one as customer. Should treat them as vendors or transfer them to employees?

Let me handle your data appropriately after the conversion, treasurer.

Before anything else, did you convert your data from outside QuickBooks? If so, it could be that the system misinterpreted the roles of the individuals. Or, it could be due to mapping or other reasons, depending on how the conversion was carried out.

Moving forward, you can label them as employees, as they function as your employees in real-life situations. Please note that QuickBooks doesn't have a direct option to change the vendor's profile to an employee. You can create a new profile for them as an employee.

Here are the steps that'll help you accomplish this process:

Step 1: Review and take note of all employee's information by going to the Suppliers page:

1. Go to the Expense menu and select Suppliers. For customer, go to the Sales menu and select Customers.
2. Find the vendor/customer name.
3. Click the Edit drop-down arrow.
4. Select Make inactive.
   

Step 2: Track them as employee:

1. Go to Payroll and select Employees.
2. Click the Add employee button and enter the information. 

Once you've paid your employee, you create a journal entry to track the payments manually in your books. For more complicated payroll transactions, I strongly advise consulting with your accountant and using this article for further guidance: Recording payroll in QuickBooks Online.
