I am new to Quickbooks. I mistakingly set up a employee as a vendor. How can I switch an Vendor to Employee without losing cheque information entered. What about wsitching Vendors to Customers or vice a versa entered by mistake when setting up accounts.

Paul, you have more than a small problem on your hands. If you have been paying the employee as a vendor, then obviously you haven't been using the payroll feature. I suspect that you were figuring out the deductions manually then issuing the check for the net amount.

If you really want to do this the RIGHT way, you have to turn on the payroll feature. Then you have to delete the old checks and reissue them using payroll. If you reconcile your bank statement every month, when you will receive a message asking if you really want to delete a cleared transaction. Answer yes. Then when you reissue the check through the payroll feature, check carefully to make sure it comes out for the same amount. If not, you will have to adjust federal and/or state withholding, because you can't adjust FICA. Then you have to click to make a "reconciled" check mark appear in the register.

When you use the payroll feature, payroll liabilities are automatically calculated. To pay them, you must do so through the "Pay Payroll Liabilities" window.

You probably could use someone who knows how to do all these things to work with you at your office to get it all set up.
