Case Study: Alterra Mountain Company reduces month-end and quarter-end close time by 30-40% with OneStream Software

Alterra Mountain Company - Customer Case Study

Alterra Mountain Company is a family of 15 year‑round ski and resort destinations formed through a series of mergers and headquartered in Denver. Their legacy Oracle HFM consolidation instance had run for more than a decade, with the original administrators gone and roughly 1,000 top‑side journal entries and misaligned fiscal years from acquired businesses — creating maintenance, reporting and upgrade challenges as the company standardized on Dynamics 365 and prepared for further acquisitions.

Working with The Hackett Group, Alterra implemented OneStream’s cloud Intelligent Finance Platform for roughly 100 users, cleaned up historical entries, and consolidated reporting, account reconciliations and close processes on a single system. The move replaced Excel and Trintech, supports multi‑currency reporting across 145+ entities, enabled faster onboarding of acquisitions, smoothed upgrades, and cut the fiscal quarter close from five weeks to 3.5 weeks — saving about 30–40% of month‑end and quarter‑end close time.
