QuickBooks Point of Sale Desktop v18 Firewall Settings

When security programs block QuickBooks Desktop Point of Sale ports, the following processes can be interrupted

  • Electronic Funds Transfer: Intuit Merchant Services credit card processing
  • Database Server Manager: (Server installation only) Ability to connect and record transactions/changes to the company file.
  • Intuit Entitlement Service: Product license and user validation

When firewall blocks connectivity between the server and client workstations, Point of Sale automatically configures the firewall for you, however, there are times that manual configuration is required.
