Section 3: Supporting Documentation
Under the TxDOT research program, there is a strong focus on adequate supporting documentation during the invoicing process. RTI maintains supporting documentation requirements as mentioned in the University Handbook, Chapter 7, Section 3 and ensures documentation requirements are met during invoice review. Invoices that are missing adequate supporting documentation are not processed until supporting documentation is provided or the expenses are removed pursuant to CRIA Article 13 “Billing and Payment”.
