I like that it's easy to use, has great features, is very user friendly with many different options which makes it super flexible, you can also sync your bookings to Xero if needed as well so there are quite a few integrations available. You cannot add custom fields in some areas of the software (eg invoices) although this could be an option rather than having to go into another program such as Quickbooks or XERO etc. If you're looking for simple but powerful cloud based accounting then flare will suit you just fine. It allows me to keep track of my business expenses, customer payments and other general information about my clients all from one place.
