Tailor-made software · Bangkok, Thailand
Tailor-made means software fitted to how your organisation actually works. Not too loose, not too tight. MERCIL measures your people, processes and constraints, then designs, builds and looks after web, mobile and cloud systems for Thai enterprises and government, long after launch.
What we build
Consultants, designers, engineers and support specialists work under one roof. You deal with one partner from the first workshop through launch and every update after, so nothing gets lost between handovers.
UX/UI design
We research with the people who will use the system, then test clickable prototypes until the interface needs little training. Decisions are tested while they are still cheap to change.
Web applications
From customer portals to internal dashboards, we build web apps that hold up in production, stay fast under real traffic and connect to the systems you already run.
Mobile apps
We build iOS and Android apps for staff and customers, from leave requests and room booking to loyalty and protected content. Every screen is designed for one thumb and connected to your back office.
Enterprise systems
We build workflow, approval and reporting systems that work with your ERP, CRM, legacy platforms and government systems. When an old system holds you back, we replace it step by step, with the data migrated and checked.
How we work
One path from the first conversation to long-term support. You see working software early, and you always know what happens next.
We learn how your business really works: the people, the process, the systems you run and the rules you follow. Then we agree what to build, and what not to.
What you get
UX, UI and architecture designed together and tested as clickable prototypes with the people who will use the system, before any code is written.
What you get
Short cycles with working software at every review. You see progress from the first weeks, and changes happen while they are still cheap.
What you get
Quality, security and performance testing, user acceptance with your team, then a go-live you can plan around.
What you get
A maintenance agreement with service levels we set together, monitoring and planned updates, so the system keeps fitting as your business changes.
What you get
Selected work
Government finance, banking, media and commerce: different problems, each one solved with software built around how that organisation works.

FAQ
Straight answers to what clients usually ask first. Something else on your mind?
Ask us directlyIt depends on scope, so we price after the Measure step rather than guessing. Quotes are in Thai baht and state clearly whether VAT 7% is included. For public-sector work, price and deliverables are aligned with the TOR so both sides can accept the work against it.
Yes. During consultation we can help an agency shape a TOR-ready scope, and we respond through the agency’s own procurement process, including e-Bidding where it applies.
Usually, yes. Most projects connect to existing systems, so we map them in the Measure step and plan integration, data migration and cut-over before anything is built.
We treat PDPA as a design requirement from the first consultation: collect only the data the system needs, restrict access by role, and make access to personal data traceable. Your organization remains the data controller, and we work with your DPO on the details.
We agree a release plan in the Measure step. Instead of one delivery at the end, you review working software at every short cycle, so progress is visible from the first weeks.
Aftercare: a maintenance agreement (MA) with monitoring, planned updates and response times agreed with you. The service levels are set together, not fixed by us.
