Originally introduced in 2001, Corona has been upgraded regularly to become a full general ledger accounting tool, yet still retains its "simple check register" appeal and price. Corona features "drag and drop" accounting, on-the-fly account creation, and one-click reconcilement. Corona is feature-laden with drag 'n drop transaction entry, autocompletion, price list, import and export, access with the OS address book, and more. Note: payroll is written primarily for use in USA.
