Bank transfers are exactly what they sound like. It's where you record a transfer from one of your bank accounts to another. There’s nothing special or magical about this.
A example of where this is probably used most often is when you pay the outstanding balance of your credit card at the end of the month. You are simply sending money from your main account to your credit card.
You wouldn't record this as an Expense as you would have already recorded all the transactions on your credit card as individual expenses, each with payments made on your credit card.
