About
A focused company.
A tangible product.
Hieu Trung Company Limited was established on 13 July 2025. Led by Ta Trung Hieu, our current software initiative focuses on building and refining tPOS.
We start with the practical work of running a shop: taking orders, recording payments, printing receipts, and understanding sales. Our direction is to make these daily tasks simpler through reliable software and carefully scoped AI features.
tPOS
From the counter
to the daily report.
tPOS is an Android application built around the café and milk tea workflow. Core ordering, payment recording, printing and reporting features are implemented; development and refinement continue.
Make each order clear
Manage products, sizes and toppings; record cash or QR transfer payments; print ESC/POS receipts and track order handoff.
Understand daily sales
Review sales by period and product, manage refunds and discounts, and export revenue records from the application.
Technology & development
Local-first foundations.
Connected when needed.
The Android application uses Kotlin, Jetpack Compose and Room/SQLite. Background synchronization supports a separate server while day-to-day selling stays on the device.
Our development approach prioritizes transaction integrity, clear staff permissions and hardware integration. Claude is part of our development workflow for coding assistance, code review, test design and documentation.

PLANNED · ANTHROPIC APIA useful assistant,
01 02 03
A useful assistant,
at the right moment.
We plan to integrate the Anthropic API into tPOS. These customer-facing and reporting features are on our roadmap, and are not currently available.
Conversational ordering
Help customers explore the configured menu, choose sizes and toppings, and prepare an order draft for customer or staff confirmation.
Customer support
Answer questions about a shop’s menu, opening hours and configured policies, with a handoff to staff when needed.
Sales report assistant
Let owners ask questions about authorized sales data and receive plain-language explanations of calculated reports.
Planned architecture: server-side API credentials, shop-scoped access, menu and price validation, and human confirmation before an order is finalized. AI features will require connectivity; core POS operations will remain independent.
