Software built to fit your business — not the other way around.
ZenTech designs and builds custom web apps, mobile apps, and business systems for companies across Sri Lanka. We also run our own product — a tuition management system used by institutes every day.
Custom systems for real operations.
Off-the-shelf tools bend your process to fit the software. We build the reverse: systems shaped around how your team already works, with room to grow.
Business web applications
Internal tools, customer portals, booking systems and dashboards — built for the workflows your team actually runs, not a generic template.
Mobile apps
Android and iOS apps for staff, delivery teams, or customers — connected to the same backend as your web systems.
Point of sale & inventory
Billing, stock tracking, and multi-branch inventory for retail, pharmacy, and F&B businesses, built to work even on a slow connection.
Integrations & automation
Connect payment gateways, SMS providers, accounting software, and government e-services so your systems talk to each other automatically.
Cloud hosting & DevOps
Reliable hosting, backups, and monitoring so your software stays up — with a team that answers when something needs attention.
Ongoing support & maintenance
Software outlives its launch date. We offer maintenance plans so bugs get fixed and features keep getting added long after go-live.
ZenTech Tuition Master
A ready-to-use management system for tuition classes and institutes — the same kind of system we build custom, offered as a service so you don't have to wait months to get started.
Run your tuition classes without the notebooks and WhatsApp chaos.
Tuition Master handles the daily admin for institutes and individual tutors: who's enrolled, who paid, who showed up, and how they're doing — all in one place.
- Student & class management
- Attendance tracking
- Fee & payment records
- SMS/email alerts to parents
- Exam marks & report cards
- Multi-branch & multi-tutor support

From first call to launch day.
Custom software fails when scope drifts. We keep it to three stages so you always know what's next.
We map the process
We sit with the people who'll use the system daily, sketch the actual workflow, and scope a plan with fixed milestones before writing code.
You see it every week
Working software, shown on a regular schedule — not a single reveal at the end. Feedback gets folded in as we go.
We stay after launch
Training for your team, a warranty period for fixes, and an optional maintenance plan for the life of the system.
A local team that answers the phone.
Based in Sri Lanka
No time-zone gap, no overseas agency markup — a team you can meet in person in Padukka, Sri Lanka.
We run our own product
Tuition Master isn't a demo — it's software we operate ourselves and stand behind daily.
Fixed-price options
Clear scope and quotes upfront for well-defined projects, so costs don't creep mid-build.
Built to scale
Systems designed for one branch today can support ten branches tomorrow, without a rebuild.
