From the branding options to the menu bar, 17Hats was build to be an easy to navigate and clean system. Whether you've been using 17Hats for 1 day or 1 year, navigating the dashboard is incredibly simple. I also appreciate the ability to access projects, contacts and invoices from a variety of places, so you can get the information you need in the most convenient way possible.
I do want to mention that 17Hats is a fairly new company. They recently released an app and a couple other features. Their company and system is still growing and evolving, so if they don't have something you need, you can request that feature to be added by going here.
I can only speak from personal experience on this, but I have always loved the customer service I've received from 17Hats. They have a help & contact section on their website, community forums and a live chat app that pops up within your dashboard. All of these give you quick access to get your questions answered.
Pricing & Plans
17Hats has a free 15-day trial here (this is an affiliate link, which means I get a month of 17Hats free if you end up loving it, thanks). This way you can get to know the interface, set up your templates and test the waters before committing.
17Hats v. Ally
Ally is 17Hat's newest release. It's all all-in-one business team that handles your clients for you. You can sign up for $799 per month and get a team of 3 people: a client assistant, account manager and a bookkeeper. This is a great option if you are looking into hiring team members but you're not sure if you can afford a full team - this is a much more affordable option for small businesses.
