Is there a way to log a cash expense?
Yes, in Emma Pro you can create a manual account and then add transactions. 
I am not talking about adding a new bank account manually for the institutions that are not supported in emma app. I am talking about cash expense, that related to no bank account.
Hi @sbma1234.
You can create a manual account for any purpose. Cash account, work expense account, anything.
What exactly do you need to record the transactions for?
I purchased electric appliance in cash from kijjji. How do I record that?
As noted above, you can only do this with a Pro account.
Create a manual account. Create a manual transaction. If you also want to track how much cash you have, you need to update the balance manually.

You might like to call your manual account ‘Cash’ and you use this to record all your cash transactions
