I did a job for $100 and the service I use charges a 10% "finders fee" of sorts. I was wondering how do I account for that fee?

Thank you for reaching out with your question about accounting for the finder's fee on the job you completed, @PJBluenose. I'd be happy to guide you through the process.

Your suggestion is a valid approach. The steps you've described for accounting for the finder's fee will indeed work well. 

In addition to this method, you may also consider creating a project as an alternative approach, especially if you're working on multiple jobs for the same customer. 

Let's start by creating a project for the specific job. Let me show you how: 

1. Sign in to QuickBooks Online.
2. Go to Business Overview, then choose Projects (Take me there).
3. Click New Project.
4. In the Project name field, enter the project name.
5. Select a customer from the Customer ▼ dropdown.
6. Enter a start and end date for the project.
7. Choose a project status from the Project Status ▼ dropdown.
8. Note: You can also add more project info in the Notes field.
9. Click Save.

Then, create a billable expense for the finder's fee, which is $10. Assign this expense to the same project you created earlier. For detailed steps, you can check out this article: Enter billable expenses in QuickBooks Online.

Lastly, when you generate the invoice for the project, add the billable expense you created. 

1. Click + New and choose Invoice.
2. In the Customer ▼ dropdown menu, select the customer you created a billable expense for. This opens the Add to invoice window.
3. Click Add on the billable expense you want to charge to your customer.
4. Select Save and close.

This way, you'll have a clear and organized record of both the job and the associated expenses.
