Best Practices and Recommendations

  1. Please break out labor and reimbursable expenses separately.

  2. Provide complete billing backup such as a system generated labor detail report or timesheets for labor and copies of all reimbursable expenses.

  3. Date and number your monthly invoice.

  4. Please invoice the entire calendar month on the same monthly invoice.

  5. Use specific dates for reimbursables.

  6. Sign up to be paid via ACH to take advantage of the most convenient and expedited method of payment.


Invoice Submittal

  1. Please submit your monthly invoice by the 7th working day of the following month; this allows Studio ORD enough time to review and compile invoices that will be submitted to the City of Chicago according to their guidelines.

  2. Invoices submitted after the deadline will be routed to the Project Manager to see if they can be billed the following month.

  3. Invoices that deviate from the template or have rates or hours exceeding what is allowed by the contract with CDA will be rejected and the consultant will need to revise the invoice accordingly.

  4. Invoices submitted without backup will be returned so that appropriate documentation can be added by the consultant.
