Thanks for your prompt response, @ShulyM.

Since your vendor isn't showing from the list, the profile may have been deleted successfully. You can also verify by checking the Vendors Center. Here's how:

1. At the top menu bar, click Vendors, then select Vendors Center. 
2. On the Vendors tab, click the drop-down arrow.
3. Select All Vendors.
4. Look for the vendor's name.
5. If it's there, click the name and press Ctrl  D.

For Customer Center, you can follow these steps below:

1. At the top menu bar, click Customers, then select Customers Center. 
2. On the Customers tab, click the drop-down arrow.
3. Select All Customers.
4. Look for the customer's name that you want to delete.
5. Right-click to select Delete Customer:Job.

In addition, we're unable to pull up reports in the following centers to show a data where vendors, customers, and employees that has no transactions. I know this report can help track customers, vendors, and employees current status to decide if you can remove or keep them.

Furthermore, I'm adding these videos as your guides:
