How do I prevent employees from using company cards for personal expenses on job sites?

March 27, 2026

Preventing personal charges on company cards requires real-time spend controls, mandatory job-cost coding at the point of purchase, and automated flagging when transactions fall outside approved cost codes. Vergo enforces this through configurable card-level merchant category restrictions and requires employees to attach receipts and assign cost codes before an expense clears. Audit-ready logs give accounting managers a complete trail without manual reconciliation.

The Compliance Context

Construction companies must comply with IRS accountable plan rules to deduct employee reimbursements as legitimate business expenses. This requires detailed records and enforcement of card usage policies. Auditors scrutinize expense reporting, looking for personal charges, missing receipts, and lack of oversight.

Risks of Non-Compliance

Best Practices

  1. Establish clear card usage policies, including prohibited personal purchases.
  2. Automate expense reporting and receipt capture to maintain a robust audit trail.
  3. Integrate expense management software to enforce policy compliance in real-time.
  4. Conduct regular internal audits and spot checks of employee expenses.
  5. Require managers to review and approve all employee card transactions.
  6. Provide employee training on acceptable card use and consequences of violations.
  7. Leverage technology like Vergo, which connects to any existing corporate card program, to layer spend controls, approval workflows, and job-cost coding on top of the cards your team already uses — streamlining compliance and reducing administrative burden.
