PowerOn® is a programming language that enables functionality on the Episys core, used by credit unions, from an end user. PowerOn files (PowerOns) are installed on the core and can be called via our SymXchange integration. Most PowerOns are a combination of business logic and front-end HTML, CSS, and Javascript.

Online banking providers, such as NetTeller, developed standard ways of handling PowerOns to perform certain actions, like the handful in this list:

  • Request to skip a loan payment on eligible loans.
  • Request a check be mailed to you.
  • Change e-statement preferences, like the email for notifications.
  • Calculate a loan payoff for a date in the future.
Our development of PowerOns is unique, because we utilize a LinkType to open the PowerOn and then present a non-native online web view to display the PowerOn itself.

Credit union configuration in Episys

This feature uses Episys PowerOn with a Banno UI. In Episys, an authorized credit union employee is responsible for installing the PowerOn and Letter Files.


An authorized credit union employee needs to install the PowerOn on their Episys Host as well. This process requires notable technical aptitude, as the installer will need to follow the instructions in this Public PowerOn Framework readme on Github for proper PowerOn installation.

Banno configuration

Once things are properly configured in Episys, a credit union employee can also perform the configuration steps that must be completed in Banno.


PowerOns are configured within Banno People:

  • Settings
  • External applications

To configure a new PowerOn:

  • After opening the External applications screen, click Create.
  • Under the PowerOn category, select the relevant link type for the PowerOn you want to configure:
    • CD Renew linktype: cd-renew
    • Change of Address linktype: change-address-usps
    • Loan Payment Skip linktype: skip-a-pay
    • Loan Payoff linktype: loan-payoff
    • Member to Member Transfers linktype: m2m-transfers
    • Open Sub Account linktype: open-subshare
    • Overdraft Tolerance linktype: odt-opt-in
