Accounting software / record keeping

I'm sure there are a few people on here that earn enough from content creation that means you are effectively self employed and need to keep records of your cost v income.

Is there any way of recording this people reccomend/use on here? I've heard a lot of good things about freeagent (not free but is bundled with some business bank accounts). I've also heard of sage and QuickBooks.

At the moment I'm keeping track of my costs In a fancy Google sheet template in anticipation of adding income to it later in the year, but if I reach more than 1k income (which I'm very confident I will do) I will need something more formal.
