An unsettled transaction can happen for a variety of reasons. Some of the most common include:
- Insufficient Funds: The cardholder’s account may not have enough funds to cover the charge.
- Authorization Declined: The processor may decline the transaction due to an expired card, incorrect details, or possible fraud concerns.
- Technical Issues: Temporary outages or disruptions between the PMS and the processor can prevent settlement.
- Communication Errors: Failed or incomplete data exchanges between the PMS and the processor may cause unsettled records.
- Cardholder Dispute: If the cardholder disputes a charge, the processor may return it as unsettled until resolved.
- Expired Authorization: An authorization obtained at check-in may expire before the settlement occurs, leaving the transaction unsettled.
Other situations — such as processor-specific rules, property network issues, or unusual transaction activity — may also cause unsettled transactions.
