We design, build, and maintain software systems that help public and private organisations work faster, smarter, and more confidently — from Turnkey Projects to flexible Outsource staffing.
Green Mount Co., Ltd. was founded on 4 July 2018 by Noppadon Petchkong, whose long career in IT gave him the vision to see what organisations truly need from their technology. We focus on computer system development for both the public and private sectors, delivering solutions that are reliable, scalable, and built to last.
“Every step of our growth must be driven by quality across all dimensions — that is the principle we never compromise on.”
We recognise that every organisation's needs are unique. Whether you want a complete solution built end-to-end, or expert hands to reinforce your existing team, we adapt to fit — not the other way round.
We study your business deeply, then design and build a complete application tailored to your exact goals. You own the result — and we stand behind it.
Already have a team but need specialist support? We provide Dedicated Resource staffing on a monthly or per-role basis, letting you scale precisely when you need it.
Our flagship focus: a fully integrated asset and inventory management platform with real-time dashboards, low-stock alerts, and API connections to ERP, HR, and accounting systems.
Not sure which technology path is right for you? Our team covers the full stack and will give you honest, practical advice — not a sales pitch.
Over 20 applications delivered across Thailand — for government agencies, listed companies, and fast-growing SMEs.
End-to-end web systems designed for performance, security, and ease of use across all devices.
Modern mobile apps that keep your team connected and productive — on iOS and Android.
Robust database design and optimisation so your data is always fast, consistent, and safe.
Holistic technology advisory covering architecture, stack selection, and digital transformation planning.
We hold every deliverable to the same high standard, whether it is a small module or a full enterprise system. Quality is our baseline, not a premium add-on.
Systems we build actively reduce overhead — less paper, fewer manual steps, faster approvals. The ROI is real and measurable, not theoretical.
We invest continuously in secure, maintainable technologies. We want the software we build today to still serve you well five years from now — not create technical debt.
We have delivered projects on time and to specification for government bodies, hospitals, logistics firms, and technology companies — and we are proud of every one of them.
Full lifecycle asset tracking with branch management, depreciation calculation, and maintenance scheduling.
A real-time online auction system handling catalogue management, bidding logic, and winner notification for multiple asset categories.
Mobile-first platform for leasing land and high-value assets, with digital contract signing and map-based location browsing.
