how to record a deposit paid to vendor/supplier by Visa on QBO?

You can record the deposit by heading to the + New button on your Dashboard and selecting the Expense tab, goingforward. Let's go through the process together.

1. Click + New and select Expense.
   
   
    
2. Fill in the necessary information, such as the Payee, Payment date, Payment account, and Payment method (select the Visa account you used for the transaction).
3. In the Category section, choose or add an appropriate account to track the deposit.
4. Enter the deposit amount in the Amount field.
5. Click Save or Save and close.
   
   

However, if this payment is made in advance for goods or services that will be delivered in the future, we can appropriately classify it under the Other Current Asset category.

It's important to handle such transactions correctly to ensure accurate financial reporting. If you're unsure about how to categorize specific payments, I recommend reaching out to a professional accountant. They can provide tailored advice to ensure everything is documented correctly in your accounting records.
 

Additionally, it's important to reconcile your account to help keep financial records accurate. It allows you to spot errors and ensure your financial information is correct and up-to-date.
