Freeagent is really intuative, like it a lot.
Sage is better for bigger companies.
My heart sinks wheneverI see a client uses Xero, hate it, but their sales pitch is great so unfortunately getting more common.
If you are a one man band then freeagent is definitely the logical way to go.
I’d classify the Sage and Xero advice the other way around from these though – in my experience Sage is created for people who think like accountants, grew up with accountancy systems on black and green screens or want to resell packages to their clients and keep them locked in. I did look at Kashflow sometime ago – as the name suggests that will be more important if your Cashflow drives your business, and is made up of many suppliers and customers.
