How A Nonprofit reduced Expense Management Errors by 75% Using Lean Six Sigma
In this case study, you’ll learn how a nonprofit reduced expense errors by 73% using Lean Six Sigma principles to improve expense reporting, strengthen financial oversight, and increase compliance with purchasing policies. The project reduced reporting defects, improved accountability, and made expense management more efficient.
By introducing standardized approval procedures, centralized expense tracking, mobile receipt capture, and improved processes, it significantly improved both process performance and compliance.
The Challenge
For credit card expense reporting, the non-profit used Emburse and handled Amazon Business purchases through separate procedures. Although employees had the possibility of submitting their expenses electronically, several ongoing problems hurt financial oversight:
- Many purchases exceeding the approved thresholds were made without documented pre-authorization.
- Receipts were not collected or retained regularly.
- Expense justifications were incomplete.
- At the time of spending, managers could not see what their employees were spending.
- Finance staff spent too much time hunting down documentation and correcting reports.
- Inconsistent compliance undermined audit readiness.
Without improvement, these issues created both direct and indirect costs, including:
- Uncontrolled spending
- Increased audit risk
- Delayed month-end close activities
- Reduced productivity
- Poor budget management visibility
Define Phase
The project objective was straightforward:
Ensure all purchases that exceed pre-authorization limits are approved, recorded, and monitored in accordance with company policy.
Success would be measured by:
- Timely expense report submission
- Complete receipt and justification documentation
- 100% compliance with pre-authorization requirements
- Improved financial visibility
A high-level SIPOC analysis identified key stakeholders, including employees, department managers, finance personnel, executives, and auditors.
Measure Phase
Current Process
A process review revealed the expense management workflow consisted of six major steps:
- Expense occurs
- Expense report created
- Receipts and justification collected
- Report submitted
- Report reviewed
- Report processed
Although the design was simple, employees varied widely in how they recorded and submitted expenses.
Potential Causes Identified
Three major potential drivers of defects were identified:
- Lack of required pre-approval before spending
- Missing receipts at the point of purchase
- Insufficient expense justification
Analyze Phase
To identify which factors most affected expense management defects, the team conducted graphical analysis and hypothesis testing.
Key Findings
The analysis revealed:
Finding #1: Defect Rates Varied by Month
Some months saw sharply higher defect rates due to changes in operating demands and purchasing activity.
Finding #2: Individual Cardholders Influenced Performance
Some cardholders caused more documentation and compliance problems than others.
Finding #3: Receipt Retention Was a Major Root Cause
Receipts were often lost or left uncollected at the time of purchase, delaying reporting and raising audit concerns.
Critical Root Causes
The team prioritized three root causes:
- Defect spikes during certain operating periods
- Higher defect rates among specific cardholders
- Failure to store receipts consistently
Improve Phase
The team evaluated several solutions based on the benefit they offered and the effort required to implement them.
Selected Improvements
- Mobile Receipt Capture
Employees could capture receipts immediately using a mobile app, reducing lost documentation.
- Centralized Expense Tracking
The team set up a central dashboard to monitor purchase requests and approvals.
- Formal Pre-Approval Workflow
The team introduced approval requirements and spending limits.
- Role-Based Approval Structure
Managers reviewed and approved spending in their departments.
- Bulk Approval Process
By combining low-dollar purchases, TLC reduced administrative work.
- Common Error Checklist
TLC provided cardholders with a checklist focused on the most common reported mistakes.
Control Phase
To maintain its gains, TLC set up an extensive control plan.
Ongoing Monitoring
The organization now tracks:
- Pre-authorization compliance
- Documentation completeness
- On-time report submission
- Budget adherence
Monthly audits and regular dashboard reviews help ensure compliance is maintained.
New Controls
- Automated reminders before reporting deadlines
- Escalation procedures for policy violations
- Budget monitoring by department
- Standardized finance review checklists
Results
Performance increased significantly as a result of the improvements implemented. Defects were reduced by 73%!
Business Impact
The project delivered:
- Improved spending control
- Stronger audit readiness
- Better policy compliance
- Greater financial transparency
- Reduced administrative effort
- Improved month-end reporting efficiency
Key Takeaways
The project shows that expense management difficulties mostly stem from process issues, not employee performance. When non-profits set clear expectations, simplify documentation, and introduce proactive controls, they can greatly improve compliance while reducing administrative workload.
The sustainable system for managing organizational spending that the Controller developed as part of his Lean Six Sigma Black Belt project improved both accountability and financial visibility at the non-profit.
