Technologies

A modern, proven technology stack

  • .NET

    ASP.NET Core is our default framework for secure web applications and REST APIs: fast, cross-platform and well suited to complex business logic and integrations.

  • React

    We build responsive, accessible React front ends for dashboards, portals and SaaS products, backed by clean APIs and a component library you can maintain.

  • SQL Server

    SQL Server and Azure SQL power many of our ERP, POS and reporting systems, offering strong transactional integrity, rich tooling and tight integration with .NET.

  • Microsoft Azure

    We design, build and run applications on Microsoft Azure: App Service, containers, Azure SQL, Functions and Azure OpenAI, with security and cost control built in.

  • Flutter

    Flutter lets us ship polished iOS and Android apps from one codebase, with smooth custom UI and near-native performance, often at lower cost than two native apps.

    We integrate OpenAI models into business software for assistants, document processing, search and content workflows, with grounding, evaluation and cost controls.

    Angular development for large, form-heavy enterprise applications where consistent structure, strong typing and long-term maintainability across teams matter most.

  • Amazon Web Services

    We build and operate applications on Amazon Web Services, using managed containers, databases, serverless functions and storage with sound security and cost practices.

  • Android

    Native Android development with Kotlin and Android tooling for apps that need deep device integration, rugged handhelds or the latest platform features.

What our clients say

  • We used to lose half a day's takings every time a store's broadband went down. Since the new tills went in, outages barely register, and head office can change a price at lunchtime and see it on every shelf-edge promotion by the afternoon.

  • Parents now have one app instead of four, and our office teams have stopped spending Monday mornings chasing absence calls. The migration was the part we worried about most, and the trial runs meant there were no surprises on go-live day.

  • The assistant resolves the repetitive how-do-I questions and hands everything else to us with a proper summary. Our agents spend their time on the tricky tickets now, and customers get answers at 2am without us adding a night shift.

  • The ERP went live in three phases, and every phase had a proper parallel run. For the first time we can see what a job actually cost against what we quoted, which has changed how we price repeat work.

FAQ

Frequently asked questions

  • What kind of software does Syntrix Software build?

    We build custom web applications, mobile apps for iOS and Android, AI-powered features and business systems such as ERP, POS, CRM and school management platforms. We also integrate and modernise existing systems.

  • How much does custom software development cost?

    It depends on scope, integrations, platforms and the level of polish required. Small focused tools can start in the low tens of thousands, while larger platforms cost more and are delivered in phases. Our software cost guide explains the main cost drivers, and we provide a written estimate after a short discovery call.

  • How long does a typical project take?

    A focused minimum viable product usually takes 8–14 weeks. Larger business systems typically take 4–9 months and are released in stages, so you start getting value early rather than waiting for one big launch.

  • Do you work with businesses outside your home country?

    Yes. We are remote-first and work with clients internationally, with overlapping working hours agreed at the start of each project and regular video check-ins.

  • Can you add AI to our existing software?

    Often, yes. We add features such as AI assistants, document extraction and smart search to existing applications through APIs, grounded in your own data. See our AI application development service for examples.

  • What happens after the software goes live?

    We offer ongoing support and maintenance, including monitoring, security updates, bug fixes and planned improvements. You own the code and documentation, so you are never locked in.
