How do I add an income in drop down menu?

Hi. How can I add an items in the drop down menu in invoice? It only has ‘interest received’ and ‘sales’.

Have you added any items to your inventory?

No, I don’t have inventory as I am a service provider. I have expenses but I haven’t got to that part yet!

By adding Income accounts under Settings - Chart of Accounts

Thank you, Brucanna. I will do that now.
