Can a customer be a supplier as well

Absolutely, you certainly can, @accounts565.

Let's make sure that every name entry remains distinct in QBO. We can achieve this by slightly modifying their name when registering the customer as a supplier. This approach will help us easily identify whether the name is associated with a customer or a supplier.

To add a supplier in QBO, you can follow the steps below: 

1. Navigate to Get Paid & Pay and select Suppliers (Take me there).
2. Select the New Supplier option.
3. Complete the fields in the Supplier Information window. Example: Customer's name is Jha, you can enter Jha S for the supplier's name (S stands for supplier).
4. Lastly, click Save.

If you find yourself needing to document a trade of goods with a customer who is also a supplier, you can check out this article for guidance: How to Record a Barter Transaction.
