We are writing to inform you of a funding discrepancy that recently came to our attention. Due to an external issue on the funding side, certain Merchant IDs experienced a shortage in deposits on June 26th, 2026.
We are working directly with our back-end funding team to ensure the affected transactions are settled and deposited as quickly as possible. We apologize for the inconvenience this has caused and are reviewing our processes to help prevent similar issues going forward. If you have any questions or believe your account may be affected, please contact our support team. Thank you for your patience and continued partnership.

Update - We are continuing to monitor for any further issues.
Aug 01, 2025 - 12:09 PDT
Monitoring - Support for PAR POS on Legacy Windows Versions has ended. For questions or assistance, please contact your PAR representative directly.
Original notification: Effective July 31, 2025, we will no longer support PAR POS on terminals and KDS hardware running:
- Windows 10 2015 LTSB - Windows 7 - Windows 8
These versions do not support Microsoft .NET Core, which is essential for future features and integrations. Upgrading to a supported Windows version ensures uninterrupted service and access to the latest functionality, including the Brink in-store API, which provides real-time data access in-store, regardless of internet connectivity. Please review the updated POS System Requirements here: https://cdn.parpos.com/docs/POSSystemRequirements.pdf

PAR has scheduled maintenance on the server hosting the PAR POS instance on 7/6 at 10:30 pm Pacific.
During the maintenance window, customers may experience brief periods of increased latency when accessing the Admin Portal or API endpoints. No prolonged service interruption is expected. We will provide an update once maintenance is complete.
Important Notice for Integrators and Partners: As part of this maintenance, PAR is implementing updates to our SSL certificate configuration. These updates introduce additional trusted Certificate Authorities (CAs) and result in a change to the certificate chain and trust path used across PAR POS platforms. While existing documentation focuses primarily on in‑store POS environments, these SSL certificate changes also apply to API integrations. Integrations that currently function may encounter connectivity issues if the appropriate root and intermediate certificates are not trusted within partner applications or infrastructure.
PAR platforms utilize a combination of Certificate Authorities, including: - AWS Certificate Authority - ssl.com - Cloudflare Certificate Authorities (including ssl.com–issued certs via Cloudflare)
Required Integrator Action (Strongly Recommended): All integrators are strongly recommended to validate SSL/TLS connectivity prior to the maintenance window by testing against PAR’s APIINT (integration test) endpoints. These endpoints represent PAR’s two primary certificate authority paths and will help confirm compatibility with the updated trust chain. Successful testing indicates that your integration should continue to function as expected following maintenance. - https://api-apiint.parpos.com/Sales.svc - https://api-apiint.brinkpos.net/Sales.svc
Support: If you encounter issues during testing or require additional technical details, please contact your PAR representative or email support.PARPOSsoftware@partech.com.

Dear PAR Payment Services Customer,
Please be advised that an issue occurred while processing the monthly PAR Payment Services billing for February 2026 which resulted in the billing file being submitted twice. The issue has been identified and solved.
To correct the issue, a credit for the additional billing amount will be issued and funded to your account on Friday, 3/13/2026. It is important not to reject the duplicate billing with your bank, as doing so will require and additional debit to be processed to offset the credit we are applying.
We sincerely apologize for any inconveniences this may have caused. If you have any questions or require assistance, please contact our support team.
Thank you,
PAR Payment Services Support Team

PAR POS 5.16 requires Microsoft .NET Framework 4.7.2 or higher. To help avoid upgrade delays or failures, please verify that .NET Framework 4.7.2 is installed on all terminals before upgrade night.
Please note: Microsoft does not support .NET Framework 4.7.2 on: • Windows 10 version 1507 (build 10240) • Windows 10 version 1511 (build 10586)
These operating systems are therefore not supported for PAR POS 5.16 and may fail during or after upgrade.
