How to categorize a credit card refund for a business item previously purchased on it?

Hi Victor

I would start by creating a credit memo under Suppliers for the returned product; then record a deposit against the credit memo to close it and mark it 'paid'.

Hi victorlinphoto,

I applaud your entrepreneurial spirit—the QuickBooks Self Employed program created for people on the go just like you. The program is a simplified version of the QuickBooks software geared towards invoicing, expensing, tracking mileage, and sales tax. I'll point you in the right direction for dealing with this transaction.

Transactions is a valuable tool with the versatility to connect bank and credit card accounts, record or attach expense receipts, and manually add transactions. To enter your supplier refund, you can manually add your transaction. Click the Add transaction in transactions. Enter the amount and choose the category. 

If you're unsure about the category you should use, I suggest reaching out to your accountant. They're familiar with your account setup and can advise you. In the case that you don't have an account, you can find one through this link: Find an Accountant.

You can always reach back out here in the QuickBooks Community if you require assistance. I'm here to help. Take care.
