Developing Internal Controls to Prevent Embezzlement
For a not-for-profit organization, trust is a major part of your work. Donors give because they believe in your mission. Board members and staff give their time because they care. The communities you serve rely on you to be responsible with every dollar.
That is exactly why internal controls matter.
Even well-run organizations can be vulnerable to fraud when processes are informal, oversight is limited, or one person is handling too much. Putting the right controls in place is not about suspicion. It is about protecting the organization, the mission, and the people who depend on it.
Understanding the Risk
Embezzlement happens when someone misuses funds or assets they have access to. In many cases, it does not start with one large transaction. It starts small and grows over time, especially when no one is reviewing the details.
Not-for-profits can be at higher risk because:
- Staffing is often lean
- Leadership may rely heavily on trust and long-standing relationships
- Administrative duties are sometimes spread thin
- Financial tasks may fall to one person out of necessity
The goal is not to assume the worst. The goal is to avoid a situation where one mistake or one bad decision goes unnoticed for too long.
Common Red Flags to Watch For
Fraud rarely announces itself clearly, but there are warning signs worth paying attention to, such as:
- Unexplained fluctuations in account balances
- Missing receipts or incomplete documentation
- Reconciliations that are delayed or not completed
- Unusual vendor payments or reimbursements
- A staff member who resists oversight or refuses to take time off
Red flags do not always mean fraud, but they should always lead to follow-up.
Why Internal Controls Matter
Internal controls are the basic safeguards that keep financial operations accurate, consistent, and reviewable. When they are working well, they help an organization stay organized and reduce preventable risk.
Strong internal controls can help you:
- Reduce opportunities for misuse of funds
- Catch errors early, before they snowball
- Improve financial reporting and board oversight
- Strengthen confidence with donors and grantors
Controls do not have to be complicated to be effective. They simply need to be consistent.
Practical Internal Controls to Strengthen
Below are a few internal control strategies we often recommend for not-for-profit organizations. Some can be implemented quickly, while others may require a policy update or a shift in workflow. The right mix depends on your team size, responsibilities, and day-to-day operations.
- Separate Financial Responsibilities
One person should not be responsible for authorizing payments, entering transactions, and reconciling accounts.
Even in a small organization, there are ways to introduce separation. For example, a board member can review bank statements, or a second person can approve payments over a certain dollar amount.
- Create Clear Approval Rules
Written approval policies reduce confusion and prevent uncomfortable “gray areas.”
A strong policy should define:
- Who can approve expenses
- Spending limits by role
- When dual approval is required
- Whether checks, electronic payments, and reimbursements follow the same rules
Clear, written rules protect everyone involved by reducing uncertainty, keeping approvals consistent, and making financial decisions easier to support later.
- Complete Bank Reconciliations Every Month
Monthly bank reconciliations are one of the simplest and most effective controls available.
Best practice is to have someone independent review them, even if they are not the person completing them. The goal is to confirm accuracy and make sure unusual activity is identified quickly.
- Review Financial Reports Consistently
Financial statements should be reviewed throughout the year, not filed away and revisited months later. Regular review is one of the most effective ways to strengthen oversight, catch errors early, and reduce the risk of inappropriate activity going unnoticed.
At a minimum, leadership and the board should review:
- Monthly financial statements
- Budget-to-actual comparisons
- Unusual variances or unexpected trends
- Major vendor payments and reimbursements
Consistent review creates accountability and helps confirm that financial activity matches what the organization expects. It also makes it much easier to spot concerns early, while they are still manageable.
- Tighten Reimbursement and Expense Documentation
Expense reimbursement policies should require:
- Receipts
- Clear descriptions of the expense
- Approval before reimbursement
If possible, reduce cash activity and move transactions to traceable payment methods. Electronic payments create a clearer paper trail, improve documentation, and make it easier to review activity later.
- Use Software Access Controls
Your accounting system should have individual user logins with appropriate permissions. Not everyone needs access to everything.
A few practical safeguards include:
- Limiting access to bank and payment functions
- Enabling audit trails
- Removing access immediately when staff transitions occur
- Reviewing user permissions at least annually
These settings matter more than most organizations realize.
- Schedule Periodic Reviews or Outside Support
Independent review strengthens accountability. Depending on your size and reporting requirements, that may include:
- Internal review by a finance committee
- An external bookkeeping review
- Audit preparation support
- An annual financial statement audit
This is not only about meeting requirements. It is about catching problems early and putting better systems in place so that they do not repeat.
- Build a Culture of Accountability
The strongest internal controls are supported by a healthy workplace culture.
That includes:
- Encouraging questions
- Making it safe to raise concerns
- Setting clear expectations for documentation
- Reinforcing that oversight is normal and responsible
Good controls work best when everyone understands their purpose.
