Thanks for laying out the details of your concern, Angela. I can help you handle these expense transactions you want to enter in QuickBooks Online (QBO).

You'll want to create a vendor and a bill to record the expense. You can follow the steps below.

Here's how to enter a vendor credit:

1. Click + New and select Vendor credit.
2. In the Vendor dropdown, choose your vendor.
3. Enter the Category details or Item details depending on how you record purchases with this vendor. Usually, this is the category, product, or service you’re getting credit for.
4. Click Save and close.

Once done, you can now enter the bill. I'd be glad to guide you on how:

1. Click +New and select Bills.
2. Choose the vendor.
3. Enter the details needed, then hit Save and Close.

Then, use the vendor credit to pay the open bill. You can follow the steps below:

1. Open the bill you want to pay and click the Make Payment button.
2. In the Bill Payment, the bill is marked as an Outstanding Transaction.
3. Go to Credits and choose the exact amount.
4. Select Add, then Save and close to confirm.

Moreover, you can record the rental income by creating a sales receipt or an invoice and receiving payment.
