TJX uses specialized computer systems to make pricing, markdown, and inventory decisions centrally for all of its stores. These systems automatically track and route roughly 11,000 items per week to each T.J. Maxx and Marshalls store, and they adjust what each store carries based on local shopping preferences.

TJX's fiscal year 2025 annual report describes "specialized computer systems designed to move inventory through our stores in a timely and disciplined manner." These systems handle allocation across more than 5,200 stores and tailor merchandise to local demographics. TJX actively recruits data professionals skilled in machine learning, predictive modeling, and advanced segmentation for its Database Marketing and Analytics teams, suggesting these foundational systems are being actively modernized. The company does not publicly label these systems as AI, but the scale and sophistication of centralized, demographically tailored allocation across thousands of stores implies advanced data-driven decision-making at minimum.
