CUSTOM SOFTWARE DEVELOPMENT

Your Business Is Unique.
Your Software Should Be Too.

We build custom software, web applications, and business tools designed around how your company actually works — not generic off-the-shelf products that require you to change your processes to fit the software.

What We Build

Software that fits the way you work

We take the time to understand your operations before writing a single line of code. Every system we build is shaped by the real problems your business faces.

Custom Software Development

Software built from the ground up around your specific workflows, data, and operational requirements — not adapted from a generic template.

Web Application Development

Full-stack web applications: customer portals, internal tools, dashboards, booking systems, or any workflow that needs a reliable browser-based interface.

SaaS Platform Development

Multi-tenant platforms with subscription management, user access controls, billing, and the infrastructure needed to serve multiple clients from a single deployment.

Business Process Automation

Replace manual, repetitive tasks with automated workflows. From invoice generation and inventory updates to notifications and report scheduling.

API & System Integration

Connect your existing tools — accounting software, payment gateways, logistics platforms, ERP systems — so data flows without manual copying.

Software Modernization

Rebuild or extend legacy systems that have become difficult to maintain, integrate, or scale. We preserve what works while replacing what holds you back.

Our Products

Selected Work

We build and operate our own software products. These demonstrate the same engineering capabilities we bring to every client engagement.

Business Solutions

Software for how real businesses work

Every industry has its own operational patterns. Here are some of the problems we help solve with custom software.

Retail & Distribution

Inventory management, purchase orders, sales tracking, supplier accounts, and GST billing — connected in one system.

Restaurants & Food Businesses

Table management, kitchen operations, menu control, billing, and daily close-of-day reporting.

Professional Services

Client onboarding, project tracking, time logging, invoicing, and document management tailored to your service model.

Field Operations

Mobile-first tools for teams that work outside the office — attendance, task assignment, customer visits, and real-time updates.

Inventory & Supply Chain

Multi-location stock tracking, reorder alerts, vendor management, and movement history across your supply chain.

Internal Business Management

HR workflows, leave management, expense tracking, approval chains, and internal reporting that fits your company structure.

How a project comes together

From the first conversation to a working system in production.

Discover

We start by understanding your business operations in detail — your workflows, your data, your pain points, and what you actually need the software to do.

Plan

We define the scope, architecture, and feature set. You see a clear picture of what will be built, how it will work, and what it will cost before development begins.

Design

Interface design, data models, and system flows are created with your team. We resolve open questions early rather than discovering them during development.

Develop

Structured, documented development with regular updates. You stay informed throughout the build — no black-box development with a surprise reveal at the end.

Test

Thorough testing against real business scenarios, not just isolated unit tests. Edge cases and integration points are verified before anything reaches production.

Launch & Support

Deployment to production with monitoring in place. Ongoing maintenance and support are available depending on your project requirements and agreement.

Why Tervino

What makes us the right fit

We don't just write code. We understand how businesses operate and build software that reflects those realities.

We start with your business, not a template

Most software problems aren't technology problems — they're workflow problems. We map how your operations actually work before deciding what to build.

We build and operate real products ourselves

GST Billing Pro and Kotkart are running in production for real users. We carry the same engineering discipline and accountability into every client project.

Direct communication, no project managers in between

You deal directly with the engineers building your software. No account management layer creating noise between your requirements and the people implementing them.

Software you can maintain and extend

We write clean, documented code with clear architecture. After launch, your software shouldn't become a black box that only we can modify.
