Transactions
What is the difference between the transaction types Refund and Income?
Transactions of type "Refund" subtract from your total expenses, while transactions of type "Income" are added to your total income.
For example:
If you have an expense of $50, and an income of $25 => Your total expense is $50
If you have an expense of $50, and a refund of $25 => Your total expense is $25
