Account Codes provides accounting information to report expenditures according to established rules for ‘rolling them up’ in financial statements, and Accounting Services has jurisdiction/decisions on account codes applied to transactions. This field can sometimes appear to overlap with both commodity code and business purpose but is intended to drive financial reporting of expenditures and is not the same as either of these fields. UW System publishes an extensive list of Account Codes on their website. Here is a cheat sheet of commonly used Account Codes for purchases. Some Account Codes require a Class field to be populated; here is a list of Account Codes and Classes.
