I've been a tax preparer for 20 years, and payment instructions and state/IRS portals to make electronic payments are a nightmare. And while some tax software can facilitate payments, some of them are hard to edit or undo once set up. I was really excited about Remitian because we finally have a unified payment experience, where I as the professional am setting up the correct payment amounts, timing, and agencies, and my client has the final approval control. And we actually get confirmation from the agencies that the payment was received! Review collected by and hosted on G2.com.
