Custom POS system development in Sri Lanka
Zeylix designs and builds custom point-of-sale (POS) systems for retailers, restaurants and service businesses in Sri Lanka. Off-the-shelf POS software often forces your business into someone else’s workflow; a custom system fits the way you actually sell, stock and report.
We build POS software that keeps billing even when the internet drops, syncs inventory across branches in real time, and gives owners the reports they need without exporting spreadsheets.
What we deliver
Retail and restaurant POS
Fast billing screens, barcode scanning, receipt printing, discounts, returns and table or order management tailored to how your staff work.
Real-time inventory management
Stock levels that update with every sale, low-stock alerts, purchase orders, supplier records and stock transfers between locations.
Multi-branch and cloud reporting
Sales, margins and staff performance across all your outlets in one dashboard, available from anywhere.
Offline-first billing
Tills that keep working through internet outages and sync automatically when the connection returns, so you never stop selling.
Integrations
Card terminals, accounting software, e-commerce stores, loyalty programmes and delivery platforms connected to a single source of truth.

How we work
- 01
Discovery
We start with a conversation, not a pitch. You walk us through what you're building and where it's stuck; we ask the hard questions and tell you honestly whether Zeylix is the right fit.
- 02
Scope & Feasibility
We pressure-test the idea against real constraints — architecture, timeline, budget — and come back with a practical plan instead of a vague estimate.
- 03
Trial Sprint
Before any long commitment, we run a paid trial sprint or POC. You see how we actually ship; we learn your product and your standards. Low risk, real output.
- 04
Long-Term Build
Once the trial proves the fit, we move into the full engagement — the same team you met on day one, weekly reporting, and a roadmap shaped by what we learned in the trial.
Frequently asked questions
- Why build a custom POS instead of buying one?
- A custom POS fits your exact workflow, integrates with the systems you already use, and has no per-terminal licence fees. It makes the most sense when off-the-shelf products force workarounds that cost your staff time every day.
- Does the POS work without internet?
- Yes. We build billing to work offline and sync sales and stock to the cloud automatically once the connection is back.
- Can it handle multiple branches?
- Yes. Inventory, pricing and reporting can be managed centrally across any number of outlets, with stock transfers between them.
- Can it connect to our existing hardware and accounting software?
- In most cases, yes. We review your current printers, scanners, card terminals and accounting tools during scoping and plan the integrations up front.
