Stop merchant fee leakage with a practical operating sprint: statement decomposition → anomaly triage → vendor actions → savings proof.

Primary outcomes:

  • Cost reduction: reduce avoidable fees and pricing drift
  • Risk mitigation: improve chargeback/refund discipline and compliance
  • Carbon impact: not applicable

The most common leakage patterns

  1. pricing drift after contract changes
  2. unnecessary gateway/tool duplication fees
  3. PCI/compliance penalties that are avoidable with basic hygiene
  4. chargeback losses and avoidable disputes
  5. “misc fees” that appear without explanation
  6. weak refund controls creating net fee drag
