Course Overview

Get Certified in Guidewire BillingCenter – Master Billing Workflows, Rating Rules & Complete Insurance Operations with Hands-On Practice.

The Iteanz Guidewire BillingCenter Developer Training is a technical, hands-on course designed for software developers who need to configure, customize, and integrate Guidewire BillingCenter. Unlike the Business Analyst track, this course focuses on the code, data structures, and architecture that power the application.

Participants will master Guidewire Studio, the proprietary Integrated Development Environment (IDE), and the Gosu programming language. The course covers the full spectrum of development tasks: extending the data model, modifying User Interface (PCF) files, implementing business rules, and creating integration points with external systems.

Prerequisites

To succeed in this technical course, attendees must have:

  • Strong Object-Oriented Programming (OOP) skills: Experience with Java or C# is mandatory.
  • XML & Web Services: Basic understanding of XML, JSON, SOAP, and REST.
  • Database Knowledge: Familiarity with SQL and relational database concepts.

Note: Prior knowledge of Guidewire is not required, but completion of the Functional/BA course is helpful for context.
