Transitioning to the AAHA Chart of Accounts (COA) is one of the best steps your hospital can take to improve financial clarity, enhance decision-making, and ensure accurate benchmarking. At Inventory Ally, we align with trusted resources like the KMS report and AAHA COA to guide practices toward smarter financial management.

This guide will walk you through the essential categories to include in your COA, helping you align with industry standards and get the most from your Inventory Ally reporting.
