Issue with Mews Reservation with wrong VAT

Incident Report for Mews

Postmortem

Problem

During the time of the incident some bookings were created with incorrect tax data due to a new front end component sending incorrect configuration. This resulted in a small percentage of invoiced being generated with invalid tax information.

Action

Once identified, the feature was immediately disabled, the code reverted, and remediation scripts were developed to correct the data. Affected properties were contacted directly with guidance on how to handle impacted invoices.

Causes

The issue occurred because a recent frontend update sent an empty array when the dropdown was disabled, which led to storing invalid tax codes in the database.

Solutions

Fixed the frontend behavior to send the correct value.

Corrected all impacted bookings and availability records.

Identified

We identified an issue with a recently introduced feature in Rate Management that impacted override pricing. This caused incorrect VAT/Tax rates to be applied to items with overrides.

The feature has now been disabled, and we are deploying a fix to prevent any new reservations from being created with incorrect VAT/Tax rates.

We are also identifying existing reservations that were affected.
Further updates will be shared here as we progress.
