I accidentally imported supplier list as the customer list. Is there an easy way to correct this

Hi there,

Since this is your first post in the Community, I'd like to give you a warm welcome! 

Don't worry, I'll help untangle this issue with you. Since you've imported the supplier list already, you'll have to manually delete those suppliers from your customer list and here's how: 

1.     From the left menu select Sales then Customers.
2.     Select the supplier or customer's name.
3.     Select Edit.
4.     On the Customer information box, select Make inactive.
5.     Once asked to confirm deactivation, select Yes.        

Based on your description, I assume you've got more than one supplier you'd like to delete, so deleting each supplier individually will be time-consuming on your end. QuickBooks allows to Batch delete suppliers and here's how: 

1.     From the left menu select Sales then Customers.
2.     Select all the suppliers in question.
3.     Select Batch actions and click on Make Inactive.
4.     Once asked to confirm deactivation, select Yes.

If you need to restore a deleted customer or supplier, here are the steps: 

1.     From the left menu, select Sales or Expenses.
2.     Under the Toolbar, select Customers or Suppliers.
3.     Above the Action column, select the small gear icon, then check Include inactive.
4.     Find the customer or supplier you need to restore.
5.     Select Make active.               

Let me knwo if you have other questions. I'm here to help. :)
