Electronic Billing System (EBS)

Telesto Technologies developed a modern Electronic Billing System (EBS) designed for businesses that require the creation, management, and reporting of electronic receipts (DTEs) in compliance with government regulations. The system enables users to create electronic invoices and submit them to the Government API, while supporting scalable architecture and enterprise-grade features such as inventory management, client handling, and contingency planning.

Problem Statement

Businesses need a reliable and compliant way to issue electronic tax documents (DTEs) to clients and report them in real-time to the relevant government API. Additionally, the system must support: modular design for easy scaling and maintainability, integration with Cloud Run microservices behind a single load-balanced endpoint, and secure, auditable, and user-friendly workflows for accounting and reporting.

Objectives

Allow users to submit all required data to create a DTE. Automatically send completed DTEs to the Government API. Use Google Cloud Platform (GCP) to ensure scalability, availability, and microservice orchestration.

User Workflow – Create and Submit DTE

Users log in and input the required data to create a DTE. The system validates input, links client and inventory data, and allows confirmation. On user approval, the DTE is sent to the Government API. The system tracks both government status and internal status for accountants and sales reps.
