You may need to configure your firewall or security software to ensure uninterrupted access when using QuickBooks Payments.

If certain ports, applications, or QuickBooks Payments web sites are not enabled for Payments services, you may experience the following problems or errors when you try to process a transaction:

	Reminders You may need to ask your system administrator for help in applying these changes to your computer's security system. When the Windows Firewall is disabled, it will automatically block all programs from any inbound connections.

If further configuration of your security settings is required, see Configure Firewall and Internet security settings for QuickBooks Desktop for details.
