I use it, but to be fair, more for bookkeeping than for accounting. It also gives me a “rough” idea of how much tax I owe which I then compare to a spreadsheet of CIS payments made on my behalf. I give my accountant a log-in and password and he submits the accounts and gives me a discount of around 80% of what the subscription to FreeAgent costs. I realise it’s old-fashioned but I still prefer to have a CA submit my accounts. Yes, I realise that whether you’re self-submitting or getting a CA to do it, HMRC says you’re just as (un)likely to be inspected but anecdotal evidence suggests otherwise.
As a user, it’s relatively neat to use, but I’m not impressed with their mobile app. I’m also shite at inputting receipts/bills/expenses as-I-go so I only have myself to blame for it being a pain in the arse once a year. 😀
