CPA Firms & Practices

CPA firms have faced growing pressure—from rising IRS audit volumes and staffing shortages to the demand for faster, more accurate client resolutions.

Enrolled Agents (EAs)

As the tax landscape grows more complex, Enrolled Agents are redefining client advocacy—and need a reliable back-office partner to handle audit documentation at scale.

Tax Resolution Specialists

As the IRS intensifies enforcement, tax resolution specialists are redefining compliance strategy—with expert workpaper preparation and notice response at the core.
