To add a transaction, tap one of the large coloured buttons on the main panorama. A refund is income that is treated as “negative spending” in the budgets and reports.
For income, spending and refunds, you can set the account and payee/payer details, and for transfers you can select the from and to accounts.
For all transactions set the category, date, amount and any notes you want to attach. For spending and transfers, you can also set a cheque number (for transfers this applies to the from account only).
For recurring transactions, set the repeat interval.
Finally turn on the reminder switch to be reminded about a transaction.
If you tap and hold the add transaction buttons, you can pin these to your start screen for quick entry of new transactions.
