Nonprofit internal controls were the missing piece that led to a significant loss of funds for a beloved community organization we recently reviewed. Sadly, the cause wasn’t a sophisticated cyber-attack but a simple lack of oversight in their accounts payable process. Consequently, this vulnerability allowed a trusted volunteer to divert small amounts of cash over three years, accumulating into a massive deficit. In fact, establishing robust nonprofit internal controls is the single most effective strategy for securing assets, preventing errors, and ensuring your mission scales successfully without fear of scandal.
Effectively, donors trust nonprofits to steward their funds responsibly, and that trust is your most valuable currency. However, many organizations operate with lean teams where one person manages the money, the books, and the vendors, creating a “single point of failure.” Therefore, implementing strong nonprofit internal controls—specifically segregation of duties, approval limits, and vendor verification—is not just about compliance; it is about protecting your reputation and your future.
Nonprofit Internal Controls: The Essential Guide to Fraud Prevention
Protect your mission with protocols, not just trust.
The Reality Check: Fundamentally, most fraud is not committed by “bad people,” but by desperate people facing a financial pressure who see an opportunity. Unfortunately, when one person holds the keys to the checkbook, the accounting software, and the bank statements, that opportunity is wide open. Therefore, effective nonprofit internal controls remove the temptation by ensuring no single individual can initiate, approve, and record a transaction without oversight.

Why Nonprofit Internal Controls Matter Now More Than Ever
Critically, neglecting robust nonprofit internal controls dramatically increases the risk of fraud, accidental misstatements, and serious grant compliance issues. Specifically, auditors and major donors now expect even small organizations to demonstrate financial maturity. Therefore, implementing a small set of repeatable protocols allows you to detect anomalies early and maintain the donor trust required for fundraising.
Real-World Case Study
A community arts nonprofit recently discovered a long-running pattern of diverted vendor payments. An anonymous tip triggered the discovery.
The root cause? One staff member handled vendor setup, invoice approval, and payments. Consequently, no checks and balances existed to stop them from creating a fake vendor and paying themselves.
The Solution: By implementing stronger nonprofit internal controls—specifically segregation of duties, third-party vendor validation, and monthly random spot checks—the organization identified the discrepant payments. Ultimately, they recovered funds and restored donor confidence.
10 Core Nonprofit Internal Controls to Implement
Fortunately, you do not need a massive accounting department to operate safely. Start by integrating these practical nonprofit internal controls into your workflow immediately:
- Segregation of Duties: Separate purchasing, vendor setup, invoice approval, and payment execution among at least two people. For very small teams, add compensating controls like dual approvals and periodic external reviews.
- Vendor Verification: Require a W-9, verify vendor contact info online, and ensure a second person reviews data before adding new vendors. Additionally, maintain a master vendor list with an authorized approver.
- Payment Dual-Approval: Set thresholds (e.g., any payment over $1,000) that require two distinct approvers. Use online banking logs to track these approvals digitally.
- Bank Reconciliations: Assign monthly reconciliations to someone who does not approve payments or sign checks. Afterward, a supervisor or Treasurer must review and sign off.
- Limited Check Stock: Restrict who can order, hold, or sign physical checks. Instead, use electronic payments with role-based access wherever possible to create a digital trail.
- Credit Card Policies: Issue cards only when necessary and strictly for business use. Furthermore, set limits, require monthly receipt submission, and reconcile card statements independently.
- Expense Reimbursements: Use an “accountable plan” to satisfy IRS rules. Require original receipts, coded expense reports, and manager approval before sending any reimbursement check.
- Random Spot Checks: Perform unannounced reviews of transactions and vendor files quarterly to detect anomalies. Knowing checks happen acts as a powerful deterrent.
- Payroll Segregation: Separate payroll data entry (hours/rates) from final approval and bank payment release. Also, reconcile payroll liabilities monthly to ensure taxes are paid.
- Documented Policies: Maintain a simple manual for procurement, travel, and expenses. Finally, train staff annually on these updates so everyone knows the rules.

Red Flags & Warning Signs to Watch For
Therefore, you must remain vigilant and proactively look for anomalies. Specifically, if you notice any of the following indicators, it may suggest your nonprofit internal controls are failing or being bypassed:
- A single person handling vendor setup, invoice approval, AND payment execution.
- Unusual vendor names, or vendors with PO Boxes but no verifiable physical address or website.
- Missing receipts or vague descriptions (e.g., “Consulting fees”) on expense reimbursements.
- Frequent write-offs of receivables or unexplained adjustments to vendor balances.
- Employees with unusually high reimbursements or frequent out-of-pocket claims compared to peers.
Tools and Policies That Fortify Controls
Leverage Technology: Use modern accounting software (like QBO or Xero) with role-based permissions to enforce segregation. Simultaneously, implement expense apps (like Dext or Expensify) that require receipt capture before submission, and utilize bank feed matching to reduce manual entry errors.
Sample Policy Language:
“Vendor Onboarding: The AP Specialist must collect a W-9 and verify all new vendors. Consequently, no vendor will enter the system without secondary approval from the Finance Manager. Furthermore, all vendor bank changes require notarized documentation and a callback to the vendor’s known contact number.”
Common Questions About Nonprofit Internal Controls
Q: We are a small team. How can we segregate duties?
A: Ideally, involve a board member or Treasurer. For example, the Executive Director approves bills, the Bookkeeper prepares checks, and the Treasurer signs them. This creates a three-person chain of custody.
Q: How often should we audit our controls?
A: Generally, conduct an internal review annually. However, if you receive federal funding, you may be required to have an external “Single Audit” if you spend over $750,000.
Q: What is the most common type of nonprofit fraud?
A: Statistically, billing schemes and expense reimbursement fraud are most common. Strengthening vendor verification and receipt policies is your best defense.
Q: Does software replace the need for controls?
A: No, software is a tool. If one person has “Super Admin” access, they can bypass software rules. Human oversight is still required.
Q: Can volunteers handle money?
A: Yes, but with strict supervision. Always have two unrelated people present when counting cash from events, and ensure they sign a count sheet immediately.
Key Takeaways for Your Mission
- Segregate Duties: Ensure no single person controls a financial transaction from start to finish.
- Verify Vendors: Always validate new payees to prevent fake vendor fraud.
- Review Monthly: Reconciling bank accounts is your primary detective control.
- Train Staff: Build a culture of integrity where everyone understands the value of nonprofit internal controls.
In Summary: Secure Your Mission for the Future
Ultimately, fraud thrives in the cracks of weak processes. Donors reward strong systems with continued funding, while auditors and regulators penalize weak ones. By taking the time to implement these protocols today, you are securing your mission for tomorrow.
