By: Wolters Kluwer Tax and Accounting

As accounting firms embrace digital transformation, the ability to connect systems and automate workflows is a necessity. The CCH Axcess Open Integration Platform makes this possible by offering a robust suite of APIs that allow firms to integrate their core systems and data sources into a unified, intelligent ecosystem.

But what exactly can you integrate with CCH Axcess APIs?

Here’s a breakdown of the most common, and most impactful, systems that firms are connecting to CCH Axcess to streamline operations, reduce manual effort, and unlock new insights.
