Accordion is a private-equity-focused business advisory and management consulting firm headquartered in New York and founded in 2009 by former Bear Stearns investment banker Nick Leopard. The firm specializes in corporate and strategic finance, M&A execution, public company readiness, turnaround and restructuring and CFO technology, working primarily with private-equity sponsors and their portfolio companies. Accordion's NetSuite capability was added in August 2022 via the acquisition of London-based ABACI, an Oracle NetSuite Silver Partner specializing in NetSuite and Workday Adaptive Planning. After the deal, Accordion integrated ABACI into its CFO Technology practice, bringing NetSuite ERP and Adaptive Planning implementation, optimization and managed-services capabilities to its private-equity client base. The combined offering enables Accordion to deliver finance-transformation programs that pair Office-of-the-CFO advisory with NetSuite as the system of record and Adaptive Planning for budgeting, forecasting and reporting. NetSuite engagements are most commonly positioned for newly acquired or carve-out portfolio companies that need a modern cloud ERP quickly. While Accordion is registered in NetSuite directories as an Authorized Partner, its identity is primarily that of a PE-focused consulting firm whose ERP services are an integrated part of broader value-creation programs.
