Scaling for Growth: ATG’s Finance Evolution with OneStream

About Auction Technology Group

Auction Technology Group (ATG) is a global technology company that powers online auction marketplaces across the arts and antiques, as well as the industrial and commercial sectors. Listed on the London Stock Exchange, ATG connects bidders from 170 countries to trusted auctioneers, facilitating the sale of millions of curated used items worth over $13 billion.

Challenge

As ATG expanded, their financial consolidation process relied heavily on Sage X3 and Excel, which became increasingly inefficient—especially after transitioning their group reporting currency from GBP to USD. The company required a scalable, automated solution to streamline consolidations, improve reporting accuracy, and integrate key financial functions into a unified platform.

What You’ll Learn

  • How reliance on Excel and Sage X3 created inefficiencies and delays in ATG’s financial consolidation process.
  • Why OneStream was the right choice to unify financial consolidation, reporting, and reconciliations in a single platform
  • How ATG leveraged OneStream’s Account Reconciliations and Task Manager to replace their old legacy system and automate key processes.
  • What made AMCO the right implementation partner—and how their expertise ensured a smooth transition in just three months.
  • The tangible benefits ATG gained from OneStream, including auditor satisfaction, efficient reporting, and scalable financial management.
