Please note employees of ASU (including RAs, TA, student works, etc.) are required to be paid through payroll.
Purchasing provides a summary of requirements to pay for Professional Services here and Tax Services has a FAQ section here.
Hiring individuals for services may require the Independent Contractor Checklist form. This must be completed and review by Tax Services before ASU can agree to pay for the service. Please see the first page of the form for a list of exceptions.
