Why Firms Switch

Marble is built for how tax professionals actually work

  • AI that helps your clients, too

    Client intake slows down when clients don’t understand what their accountant is asking for, which document they need, or how to answer a tax-specific question. Marble brings AI directly into the client experience, helping clients understand requests and answer questions while they complete intake. Your team maintains visibility into the process, including where clients need help, so fewer questions have to turn into another email or phone call. Less confusion for clients. Less back-and-forth for your team.

  • Documents become structured data

    Collecting the document is only the beginning. Marble identifies incoming tax documents and extracts relevant information into structured, reviewable data. Your team can validate the information and create export-ready outputs for downstream tax work instead of manually transferring information from documents into the next system. Collect → Identify → Extract → Review → Export Intake becomes the beginning of tax preparation—not just document collection.

  • Collaboration where the work happens

    Tax work rarely happens alone. Marble includes internal messaging so preparers, reviewers, and other team members can collaborate directly around the engagement. Instead of moving conversations between intake software, email, chat, and separate workpaper tools, your team can keep discussions connected to the work itself. Documents, data, workpapers, review status, and conversations stay together.
