HUIT delivers IT services to the Harvard community, supported primarily through cost-recovery financial models across multiple service areas. Departments are charged through Harvard's general ledger system, and affiliated institutions are sent invoices for payment through Harvard's accounts receivable system. Monthly statements itemizing service quantities, rates, and GL coding are electronically sent to the designated financial contacts for each HUIT account.

A HUIT customer account is assigned as part of the initial subscription process for HUIT services. Each HUIT customer is assigned a unique customer code of the format of "B" and 5 digits. This customer code is referenced on all statements and GL transactions. A single department/school may have one or more HUIT customer accounts depending on budget complexity.
