Preventing and managing chargebacks

Reduce disputes with clear labels, fast refunds, and telemetry.

Updated Feb 9, 2026

Overview

Post clear contact information and a short refund policy on every machine. Most chargebacks happen when customers cannot find a fast way to resolve a $2–$5 issue.

Use telemetry to verify vend success and track repeat failures by column. Resolve failed vends quickly and document the refund in a simple log with transaction ID and resolution time.

If a chargeback occurs, respond within the processor window with telemetry evidence, refund receipt, and a photo of your contact label.

Transaction verification

  • Validate each disputed charge against the vend log.
  • Confirm the reader transaction ID and timestamp.
  • Save portal screenshots for each response.

Network and power checks

  • Check for intermittent offline periods that cause duplicate taps.
  • Confirm firmware is current to prevent reader glitches.
  • Replace worn MDB cables that cause random disconnects.

Dispute prevention

  • Keep contact labels large and easy to read.
  • Respond within 24 hours to preserve processing ratios.
  • Provide proactive refunds for verified failed vends.

Expanded guidance

  • Confirm all steps are documented so the next technician can reproduce the results.
  • Capture before/after metrics (errors cleared, sales restored, or uptime improved).
  • Review machine, reader, or route settings to ensure they match location standards.

Common pitfalls

  • Skipping a controlled test leads to false positives.
  • Updating hardware without documenting configuration changes.
  • Forgetting to verify payout, refund, or reconciliation data after changes.

Next-step checklist

  • Run a final test with known-good inputs.
  • Log the outcome with date, time, and device identifiers.
  • Schedule a follow-up check if the location has high traffic or seasonal demand.
