Hi, How can I post a journal to supplier account for early payment discount received?

I'll walk you through creating a journal entry for a supplier, Accounts-corcora.

You can follow these steps:

1. Click the New or Plus sign (+) button.
2. Select Journal entry.
3. Fill in the necessary fields.
4. Click Save and close.

I'll also include this reference to guide you better: Create a journal entry in QuickBooks Online.

Or, you may also want to enter a supplier credit instead. You can apply it to an open bill. 

If you have other questions, don't hesitate to let us know. We're available 24/7 to assist you. Keep safe!
