The goal
Give every ATG client a single, secure hub for tax work, and give the ATG team the controls to manage clients, content and access from the other side.
02
The challenge
- 01Clients have a lot to hand over: documents, organizers, engagement letters and answers.
- 02Different clients need different tools — individuals, rental property owners, flippers and business owners.
- 03The firm's team needs to see activity, assign services and control who can access what.

Two sides, one system
A client portal and an admin console designed together, so every client action has a matching team view.
- 2
Organizers that fit the client
Personal, rental property and flip organizers plus an income & expense tracker — each built around the questions that matter.

Secure by design
A document center and uploads built for sensitive financial files, with permission controls on the admin side.
