Hi there, @mberry4719.
To post a rebate check to a vendor, you can create a bank deposit in QuickBooks Online. Then, you’ll want to assign it to an expense or cost of goods sold (COGS) account that you originally used to make purchases with this vendor.
It would be great to work with your accountant on this matter. To ensure everything is properly recorded in the system. Here are the steps:
- Select the +New button at the left top.
- Click the Bank deposit.
- Choose the bank account where you want to deposit the amount.
- Select the vendor name in the Received From column.
- In the Account column, choose the account where it should be posted.
- Enter the amount and hit Save and close.
You might want to check this article for more information about the process: Record and make Bank Deposits in QuickBooks Online.
In case you need some details with your deposits, you can always generate a Deposit Detail Report in QBO to view them.
Please let me know if you need further assistance. I'm just right around the corner if you need me. Have a good day!
