SHOP.COM
I spearheaded the critical upgrade of SHOP.COM's tax engine from August 2019 to November 2020, a strategic initiative necessitated by evolving tax laws and our growing transaction volume. This project was central to their mission to enhance operational efficiency and compliance across the United States, ensuring our tax team was equipped with state-of-the-art tools for sales tax remittance across thousands of jurisdictions.
My leadership in this complex endeavor began with a strategic vendor selection process, through which Thomson Reuters ONESOURCE was identified as the optimal solution to meet our multifaceted marketplace needs. Recognizing the importance of a unified approach, I led the orchestration and direction of diverse teams across various divisions, achieving a centralized sales tax calculation process that marked a significant leap in our operational restructuring.
The initiative required a comprehensive overhaul of all tax-related processes to integrate with the new central service. My focus on process optimization ensured a cohesive and streamlined operation, significantly enhancing our tax calculation efficiency. Anticipating potential challenges, I implemented a fail-over system to maintain continuity of operations, a decision that underscored our proactive approach to risk management.
The successful implementation of the project within a mere six months, without any system issues, stands as a testament to our meticulous planning and execution. Notably, the migration was accomplished within the budget constraints of our previous tax engine, exemplifying our commitment to fiscal responsibility. The transformation achieved through this project not only reduced the IT team's support hours by 100%, freeing up significant resources for further innovation, but also demonstrated my capability in steering SHOP.COM through a period of significant technological and operational change.
My role in this transformative project not only bolstered SHOP.COM's position in the marketplace but also reinforced my reputation as a technology executive capable of leading complex digital transformations. Through strategic foresight, innovative solutions, and effective leadership, I was able to navigate the project to success, underscoring my commitment to driving operational excellence and compliance in the rapidly evolving e-commerce landscape.
