Overview 
The Multi-Site Accounts feature utilizes the Sierra Shared Payments application to allow 
accounts stored on a site controller to be used at other locations. While accounts can only be 
set for multi-site sharing when they’re stored on a controller, accounts can be used at any site 
with a Portal, C-Start, Sentinel, WashPay device or Wash Select II (when its connected to a site 
controller). Account types supported are Prepaid, Fleet, Subscription (unlimited wash) and 
loyalty. Account sharing is a software option that requires the purchase of an activation code. 
This document refers to sites as either Publishing or Remote. A publishing site is one where the 
site controller is configured to share its accounts so they can be used at other sites. All 
deployments must have at least one publishing site. A Remote site is one where multi-site 
accounts can be used but no multi-site accounts are stored. 
System Requirements 
  Requires sierra version 1.63 or higher at all sites. 
  Requires the Sierra Enhanced Marketing Option at all sites. 
  Requires the Shared Accounts option to be enabled on site controllers at all publishing 
sites 
  Requires a static IP Address at all sites with port 9820 open for external access 
Setup 
To configure a site controller for sharing its accounts, the following information is needed for 
each site where the accounts can be used: 
  Site IP address 
  Zip Code and Time Zone 
  Database ID for the Sierra server application 
Once this information is available, and all system requirements (as described earlier in this 
document) are met, follow the steps below to configure the site controller at each Publishing 
site. No programming is required at remote sites. 
1.  Login to the Sierra management system on the server. 
2.  Go to the Setup tab, then go to Activation Codes. 
3.  Verify that you have a Shared Payment Service and House Account and Gift Card 
Support codes. If you do not have them, please call 1-800-4-Unitec and have one setup. 
You will need to restart the server after the new activation code has been added, by 
going to the Utilities tab, then clicking Restart Server.
