Hi there, Nerri.
I'm happy to point you in the right direction to have this commission accounted for in QuickBooks Desktop.
In this instance I recommend consulting with your accountant about the best action moving forward. Your accountant will be able to advise you of the best way to get this entered based on your unique business setup and workflows.
If you don't currently have an accountant you can find one in your area specifically trained in QuickBooks by searching here: Find a ProAdvisor
Please feel free to reach back out in the comments below if you need a hand with the entry. I'll be here to help in any way that I can.
