I'm Trying to figure out how to include a tip when receiving a payment. Example, Invoice was for 450.00 but the customer paid 540.00. how do i acct for the 90

I'll help with your question about adding tips in QBO, steinke-nick-gma.

You can create a service item to track the tip. Then, edit the invoice after receiving the payment and add the tip in the second line item. Here's how:

1. Go to the Gear icon and select Products and Services.
2. Click the New button and choose either Service or Non-inventory.
3. Enter the tip details and go to the Sales information section.
4. Select the tip account in the Income account field. You can also create a new account that will be specifically used for tip income. Just click the Add new option and enter the required details.
5. Click Save and close.

Once done, open or edit the invoice. Then, go to the second line item and add the tip that you just created.
