For 30 years, Cornerstone Information Systems has helped procurement and travel teams make better decisions with data they can actually trust. Travel and spend data sits scattered across booking tools, TMCs, card feeds, expense platforms, and ERPs, leaving travel and procurement teams to stitch the story together every time leadership asks. Cornerstone's travel operations technology has processed, automated, and reconciled over 10 billion transactions for the world's largest travel programs. Upstream, our data platform, connects 63+ systems to deliver total trip cost across the enterprise: what was booked, what was charged, and what was expensed on every trip. One platform, one view. That means QBRs you can walk into prepared, hotel RFPs backed by clean data, leakage you can finally find, and savings you can actually prove. 500+ enterprise programs run on Cornerstone.
