Documentation goes beyond basic receipts and invoices, requiring a comprehensive narrative that explains each transaction's purpose, approval, and alignment with federal requirements. Organizations must ensure every financial record clearly shows who authorized the expense, why it was necessary, and how it was allocated, especially when federal funds are involved.
Key Insights
- Provide thorough written justifications for expenses to demonstrate allowability and allocability, including clear documentation of approvals by authorized personnel.
- Maintain accurate time and effort certifications to support salaries charged to federal awards, ensuring alignment with actual work performed and payroll records.
- Document consistent cost allocation methodologies and apply uniform financial policies across all funding sources to withstand audit scrutiny.

When we talk about documentation, it's important to recognize that auditors aren't just looking for invoices and receipts. They're looking for a full narrative of the transaction, the who, what, when, where, why, and how. And each of these elements must be supported by written evidence.
Let's walk through the key categories of documentation that every organization must maintain. First, we need clear descriptions of the nature and costs. This is often where organizations fall short.
An invoice might show what was purchased, but it rarely explains why the cost is necessary for the federal award. A simple written justification, a few sentences, can make all the difference in demonstrating allowability and allocability. Next, we need approvals from authorized personnel.
This can be signatures on requisitions, documented approvals in a financial system, or email confirmations. What matters most is that it shows oversight and that the individual approving the expense has the authority to do so. From an audit perspective, unauthorized approvals are treated the same as no approval at all.
A critical piece of documentation involves time and effort certifications for salaries and wages charged to federal awards. This requirement is rooted in 2 CFR 200 subsection 430. If staff are billing time to a grant, the organization must be able to demonstrate that that time was actually worked, not assumed, not estimated, not retroactively created.
Certifications, timesheets, or system-generated reports must match the payroll charges precisely. We must also maintain invoices, receipts, contracts, and purchasing orders, especially for procurement costs. These documents tell the story of the transaction, the vendor selected, the reasonableness of the price, and whether procurement rules were followed.
Another essential component is allocation methodologies, particularly when costs are shared across multiple programs or cost objectives. Auditors will ask, how did you decide this cost belonged 40% to Program A and 60% to Program B? If the methodology is not documented and consistently applied, the cost is vulnerable to disallowance. Finally, the uniform guidance requires consistent application of policies across all awards, including non-federal activities.
If a cost is treated one way on one federal award, indifferently, and in an unrestricted account, auditors may question whether the organization is shifting costs or selectively applying the rules. The overarching theme here is consistency, clarity, and traceability. Documentation should answer questions before an auditor even asks them.
When the story is clear, the cost is defensible.
