Been using for 1 year, at it's core it works and provides a nice alternative to keeping your data in a spreadsheet and the online integration with self assessment is nice; but there are 3 huge flaws I am struggling to get over and looking to alternatives. 1) No ability to download or export your invoices OR expenses. This is criminal, it's sensible to have an offline copy of these vital documents (even FreeAgent agrees) but there is no way to do this. All the invoicing & cloud accounting packages I have tested have this basic ability but FreeAgent is the only one who can't (and won't) add this feature despite it being requested on the support forums since 2012 *see note 3. 2) Design. The branding and the invoicing are not very nice. Send a client an invoice with online payment and you get a massive "JOIN FREEAGENT" logo plastered all over it, which is a bit unprofessional and I have had raised eyebrows. Worse still, many things have their mascot - a cartoon cat in a suit and tie - everywhere. 3) Feels like development stopped 5 years ago. If you read the support forums there are many basic features people have asked for and it's apparent that people have been asking for the same things since 2012 and nothing ever seem to get done. On the positive side: 1) Easy to use, the app works well for creating expenses on the fly 2) Integrates with Stripe / Paypal / Bank's well 3) Provides a few more tools than invoicing services like FreshBooks 4) Very good customer support. 5) UK based, so better geared for UK tax system.
