KR vs PAYX Comparison

Founded in 1883, Kroger is the largest pure-play supermarket operator in the United States, operating roughly 2,700 stores across more than 30 banners. Kroger's business is primarily grocery-led (roughly 79% of sales), spanning fresh food and private-label offerings, complemented by fuel centers (9%) and pharmacies (12%). The firm also generates income from advertising, data analytics, and manufacturing.

Paychex is a cloud-based human capital management provider offering payroll, compliance, talent management, benefits administration, and retirement services. The firm also provides HR outsourcing services, including professional employer organization, or PEO, offerings, enabling clients to reduce HR overhead. Paychex primarily targets small and midsize businesses, although its acquisition of Paycor in 2025 signals the firm's aspirations to expand into the midmarket segment, serving firms with more than 100 employees. As of fiscal 2026, Paychex has approximately 840,000 clients and manages payroll for one in 11 workers in the United States.
