PRODUCTS

These are HARO’s in-house products, actually used in real business operations.

EST is an HR and labor management system for Japanese companies operating in Vietnam.
With automatic integration of attendance and payroll, and automatic compliance with local labor laws, it significantly reduces on-site confusion and human errors.
You can centrally manage information in Japanese and Vietnamese.

E-Document is an enterprise system designed for long-term operation, driven and managed in-house, integrating document management and approval workflows.
It consolidates essential features for document operations—such as multi-step approvals, history tracking, and deadline management—so you can run it flexibly in line with your business rules.

A next-generation production scheduler that automatically builds production plans.
It simultaneously considers multiple conditions such as equipment, processes, capacity, and delivery dates, and quickly creates executable plans that can be used as-is on the shop floor.
No complex operations or specialized knowledge are required. Nova transforms production planning from a “person-dependent task” into a “reproducible system anyone can use.”
