I invested some money to my Inc. how can I show that as expense or conventional note?
Thanks for your time reaching us out here in the Community, shahrouzalimo.
You can consult your accountant on which two options best apply to your business. If you'll want to record it as an expense, just manually add the transaction and choose Other business expenses category on the list.
Go to the Transaction menu.
Choose Add Transaction.
Enter the amount and a brief description.
Browse the Select a category menu and select Other business expenses.
Tap Save to record the transaction.
I have here some articles about the categories in QuickBooks Self-Employed for your future use:
