How Sidhyati built a multi-country e-Tax and invoicing platform for organizations across Southeast Asia, cloud-native on AWS and delivered through an AI-driven software development lifecycle.
Invoicing is core to every business, and automating it has become essential to eliminate manual effort. Invoice types vary by organization, and regional tax laws apply VAT, GST, or other local taxes, all of which had to work across multiple Southeast Asian countries. Sidhyati delivered ETax, a quick, error-free invoicing platform, running cloud-native on AWS and built through an AI-driven engineering process.
Handwritten records were slow and error-prone, and changing tax rates meant costly effort to update invoice formats and calculations.
With many billers each having custom needs, creating one standard e-Tax and invoicing system was difficult. Key factors were performance and scalability, customization, and compliance with government tax laws and data integrity.
We built ETax on AWS, using managed cloud services for elastic scale, high availability, and secure handling of financial data across regions.
Delivery ran on an AI-augmented SDLC: AI-assisted analysis structured multi-region tax rules, AI pair-programming and automated tests sped the build, and AI code review kept quality high across every sprint.
