By replacing legacy friction with a validated, mobile-first ecosystem, Tonic3 engineered a better experience for the users of the Intuit ProConnect product line. By weaving large-scale user testing with custom engineering, a blended team ensured a high-performance launch that drives long-term customer loyalty. 

 

### **The Challenge: Overcoming the Adoption Gap in Legacy Ecosystems**

Intuit’s ProConnect Division faced a critical bottleneck: more than 150 pages of content lived on a legacy system that lacked mobile responsiveness and a cohesive user journey. To maintain market leadership, they required more than just a "facelift"; they needed a complete migration to a new Content Management System (Adobe Experience Manager) and a navigation system that could support high-volume, professional users without delivery drama.

### **The Approach: Tonic3's Blended Differentiator**

Intuit’s product team partnered with Tonic3 to modernize a legacy, non-responsive ecosystem into a research-driven, mobile-first AEM platform that improves conversions today and sets a scalable, AI-ready foundation for future growth.

- #### **Replacing Guesswork with Validation**
  
   Our process began by auditing the Marketing Department’s proposed information architecture. **To eliminate the guesswork** that often plagues large migrations, we de-risked the project through rapid UX prototyping. We conducted large-scale remote user testing of critical content organization within the first two weeks, ensuring the navigation system was engineered for "stickiness" before a single line of production code was written.
- #### **Engineering Velocity and Rigor**
  
   To meet the aggressive 8-month launch window, our technical team worked in lockstep with designers to build a library of reusable components. This focused execution allowed for the rapid creation of tablet and mobile views as desktop designs were finalized, ensuring enterprise-grade standards and high-volume output during the AEM migration.
- #### **Architecting for Intelligent Future-Proofing**
  
   The new digital ecosystem was built on a data-first, modular structure. By organizing the 150+ page migration with clean, categorized data paths, the ProConnect site is now architected to be AI-ready, allowing for future integration of automated customer support agents or personalized intelligence experiences.

### **The Impact: Strategic Performance & Sustained Conversion Growth**

Intuit ProConnect went live on time and within budget. Intuit has since experienced significantly improved conversion rates for both free trials and product sign-ups.
