I have spent literally years trying to find the right accounting app for me, as a freelancer. At this point, I've used about all of them. I tried QB Freelancer in it's first year and it had far too many bugs. I used Harvest but it didn't have all the features I needed. I tried Freshbooks but it just didn't work and it lacked features. These other platforms all want to just be an expensive cog with a million addons or are just too case-specific or just plain buggy. Frustrated to the point of just using good ol' excel sheets, I found FreeAgent. These guys do just about everything perfectly. It honestly is hard to express that. They had a slightly older UI when I started, but they're already working on a new one (I'm in the Beta, and it's awesome). I have my invoicing, time tracking, expense tracking, and all the important stuff right in front of me. I have the usual big-options for getting paid, paypal & stripe, plus banking details for check-payment on the invoice. It will automatically match bank transactions to payments where possible. You can link 1 huge payment to multiple separate invoices (and it keeps track to make sure you don't get underpaid). There is multi-user support, so I can have employees/contractors work within my business to track their working hours and manage invoicing smoothly and efficiently. I can rebill expenses, with markup to clients. There's reports, which I use all the time to get a quick glance at what the next round of invoices should look like. I can get account statuses/summaries for any delinquent clients, and it is just amazing. No other platform I've worked with had all of these features. None of them were this affordable. And none of them were working this hard on improving their product.
