Have you ever noticed employees submitting the same receipt for recurring charges? Or managers approving out-of-policy travel just because it's "urgent"? Have you caught reimbursements for mileage, even though the employee already receives a commute stipend via payroll? Or faced the classic excuse: "I lost the receipt"?
These patterns are all too familiar — and they point to a deeper issue: weak policy enforcement, not just bad habits. Finance teams shouldn't have to play expense police. The solution isn't more manual review — it's smarter integration and stronger ownership.
This article outlines best practices for embedding compliance into travel and expense processes through robust policy design, strategic system integration and a finance-led approach to corporate card controls. Drawing from real-world implementation experience, it provides a roadmap for companies looking to close compliance gaps without slowing down business operations.
Why T&E policies deserve strategic attention
T&E expenses are often decentralized, high-frequency, and subject to scrutiny from both internal and external stakeholders. Left unchecked, they can expose companies to material weaknesses in internal controls, particularly under SOX, and trigger IRS compliance risks.
A poorly written or inconsistently enforced policy can result in:
- Fraud and duplicate submissions;
- Unallowable or non-compliant reimbursements;
- Tax reporting inaccuracies; and,
- Budget overruns and misclassified expenses
Because T&E touches nearly every employee, it's also one of the few areas where finance must carefully balance user experience with policy enforcement.
A T&E policy is only effective if it's visible and enforceable. Embedding rules directly into expense tools like Nexonia, Concur or SAP promotes real-time compliance and removes subjective decision-making from the process.
Key integration points include:
- Expense categories and thresholds mapped to GL accounts;
- Tax configurations for meals, mileage and per diems;
- Automated alerts for duplicates, out-of-policy items and missing receipts; and,
- Booking restrictions and pre-approval workflows in platforms like AmTrav or Egencia.
Too often, companies configure their systems after writing a policy, creating loopholes, workarounds and inconsistent enforcement.

Corporate credit card controls
When it comes to corporate cards, clarity and control are essential. A strong T&E policy should define:
- Eligibility criteria (e.g., client-facing roles or frequent travelers);
- Spending limits based on role or historical data;
- Merchant Category Code restrictions (e.g., blocking luxury goods or alcohol); and,
- Real-time enforcement rules to auto-decline out-of-policy charges.
Controls must govern the full lifecycle — from issuance and training to monthly review and revocation for misuse. Importantly, system-enforced controls are more reliable than relying solely on manual review or manager oversight.
Finance as system owner (not just approver)
While IT and procurement often implement systems, the finance department must lead T&E policy and configuration. Why? Because finance is accountable for:
- IRS accountable plan compliance (substantiation and timely reimbursement);
- SOX internal control effectiveness; and,
- Accurate forecasting, audit trails and budget alignment.
When finance owns the system rules, card programs and policy enforcement strategy, companies ensure T&E supports both governance and strategic goals, not just operational convenience.
Best practices for enforcement without micromanagement
Being proactive doesn't mean being punitive. The goal is to create automated accountability, not a culture of surveillance.
Best-in-class enforcement practices include:
- Writing and finalizing the policy before implementing the tools;
- Requiring mobile receipt uploads and automated audits;
- Monthly reconciliation with exception reporting;
- Configured approval workflows by expense type and threshold;
- Regular training sessions for employees and approvers; and,
- Clear disciplinary pathways for repeated violations.
A well-trained workforce and system-driven workflows reduce the need for manual policing, making compliance scalable and sustainable.
Every expense report should be reviewed and approved by the employee's direct manager before reaching finance. Managerial approval should not be treated as a formality — it's a critical control point in the compliance process.
Managers are responsible for:
- Ensuring expenses are reasonable, necessary and compliant with policy;
- Verifying business purpose and context; and,
- Rejecting incomplete or questionable submissions before a Finance review.
When managers actively participate in the approval process, it reduces the burden on the accounting team, improves compliance at the source, and reinforces policy literacy across departments.
Risk reduction and strategic value
When T&E policy is embedded into systems and managed by finance, the results are tangible:
- Fewer compliance violations and audit exceptions;
- Reduced fraud and manual error risk;
- Cleaner data for reporting, forecasting and closing cycles; and,
- Greater visibility into department-level and company-wide spending.
This shifts T&E from a tedious back-office process to a strategic function that enhances financial integrity and supports organizational accountability.
In today's hybrid, fast-moving business environment, relying on manual review or goodwill for expense compliance is no longer viable. A well-crafted, fully integrated T&E policy acts as both a financial safeguard and a strategic compliance tool.
Whether you're evaluating expense tools, launching a card program or preparing for an audit, treat your T&E policy as a core pillar of financial governance, not just a reimbursement checklist.
