Best workflow management tool on the market

The best decision you need to make if you own a bookkeeping practice is the choice of your practice management software. I believe this is where you should economize on this decision. Karbon is definitely the best option out there. We have been using Karbon since 2017, and we continue to improve our processes and take advantage of their continuous improvements. 5-stars all over!

Keeping the dispersed team connected

Syncing with my Outlook email and calendar helps me prioritize my day. The project management side gives me visibility into my team's work. Karbon's functionality allows our bookkeeping and accounting teams to keep projects on track and ensure future projects don't get missed. I appreciate the insights into what is being worked on, the due dates and the workflow.

Finally in control of my practice

There are many features I love, but overall, I love being able to see at a glance exactly where we are with client deadlines and what we need to prioritize. Before this, the practice management system I was using required me to download data into Excel, mess about for hours and the next day, it had all changed. I love being able to allocate work directly from my inbox, moving things to My Week to do later — it's great!

Aero is a simple accounting workflow tool that helps sole accountants or bookkeepers manage their jobs and tasks online.

It’s not a true practice management software because it lacks key features of a practice management system like client communication, team collaboration, and email integration. As a result, firms of three or more team members might struggle with the limited functionality offered by Aero.

But if you’re a sole practitioner looking to upgrade your project management and workflow tools from manual spreadsheets and to-do lists to a digital solution, Aero is an option.

Karbon is a practice management platform built for teams to work and collaborate more effectively with each other and their clients.

If your accounting, tax, or bookkeeping firm has five or more employees, or your small CPA firm has plans to grow and scale in the near future, you’ll find your team saving hours on manual tasks like providing status updates or chasing clients for information with Karbon.

Plus, Karbon gives you 360-degree visibility across every aspect of your practice—from your work-in-progress, to what’s being said to clients, to how many client engagements are over/under budget.

Karbon integrates with Gmail, Microsoft Outlook 365, Microsoft Exchange, DropBox, OneDrive, and an ever-growing suite of popular accounting apps including QuickBooks Online, Ignition, GoProposal, and more. You can also connect Karbon to over 5,000 apps through Zapier. To learn more about Karbon’s integration capabilities, visit the integrations library here.
