Microsoft vs. Automatic Data Processing: Scale vs. Seasonality in Revenue

The article compares Microsoft and Automatic Data Processing through revenue scale and growth trajectory, arguing that Microsoft is the stronger long-term growth story despite ADP’s scale in payroll and HR services. Microsoft’s quarterly revenue has risen steadily at a mid-teens pace over the last eight quarters, reaching $90.0 billion in Q2 2026, while ADP’s revenue has grown more slowly at a mid-single-digit rate and shown seasonal volatility. Microsoft’s annual revenue reached $388 billion, up 18% year over year, helped by 43% Azure growth and growing Copilot adoption with more than 30 million paid seats. ADP’s AI and cloud tools, including The Zone and Canada Pay Insights, have not meaningfully accelerated revenue growth. The market takeaway is that Microsoft’s AI and cloud leadership may continue widening its revenue gap versus ADP, reinforcing Microsoft’s premium growth profile.
