how i can see a credit in qb destop?

I'll help you see the credit, @contadora23.

Usually, you can see the customer credit when you receive payments if you retain it as an available credit.

Here's how:

1. Select Customers and then Receive Payments.
2. Under the Received from drop-down, select your customer.
3. Then, select the Discounts and Credits icon.
4. On the Credits tab, you can see and check the credit you want to apply and then Done.
   
5. You may see a prompt to Confirm transfer. If you do, select Yes. The amount will be applied automatically to the invoice.
6. Select Save & Close.

Also, you can see it in the same spot (Discounts and Credits) when you created a refund for a customer's overpayment. You can reference this article for more insights: Give your customer a credit or refund in QuickBooks Desktop.

However, if you're referring to vendor credit, you can go to the Vendors menu and then select Enter Bills. When you tick on the Credit radio button this will show you the credit. You can also scan previous bills and credits created for a specific vendor by clicking the Forward and Backward arrows.

I've added screenshots for visual references.


 

For reference on how to see the available credits and apply them to a bill: Record a vendor refund in Quickbooks Desktop.

Additionally, you can also run reports for Transaction List by Vendor or Transaction List by Customer to see the bill/invoice and the credits applied.
