What We Build: Custom Software for Every Layer of Your Business
Custom software development covers a wide range of deliverables. We do not specialise in one narrow niche. Instead, we match our capabilities to your specific requirements, whether that means a customer-facing web application, an internal automation tool, or a fully commercial SaaS product.
Web Applications
We build data-intensive web applications for internal teams and external users alike. Think operations dashboards, customer portals, booking platforms, and reporting tools built to handle real workloads rather than demo traffic.
Desktop Applications
Not every solution belongs in a browser. We develop Windows desktop applications using WPF and .NET MAUI, including cross-platform tools that run on Windows, macOS, and mobile from a single shared codebase.
SaaS Platforms
We have built commercial SaaS products from the ground up, including a fully featured antidetect browser platform with subscription management, user isolation, and multi-account browser profiles. If you have a SaaS idea, we can take it from architecture to launch.
API Integrations
Legacy systems, third-party services, payment gateways, ERP platforms: we connect them cleanly. Our integration work covers REST, GraphQL, SOAP, and event-driven messaging patterns using tools like RabbitMQ and Azure Service Bus.
Business Automation Tools
Repetitive manual processes cost money and introduce errors. We build automation tools that replace spreadsheets, manual data entry, and disconnected workflows with reliable, auditable software.
AI-Powered Applications
We integrate large language models, computer vision, and machine learning pipelines into production applications. This is not prototype work. We ship AI features that operate in real environments, as our ropeway safety dashboard project demonstrates (more on that below).
Our Technology Stack: 20+ Years of .NET at the Core
Technology choices matter. We have built on the Microsoft .NET platform for over two decades, which means we understand its performance characteristics, its edge cases, and its long-term support roadmap. That depth of experience shows in the quality and maintainability of the code we deliver.
Backend Technologies
Our primary backend stack is .NET and C# with ASP.NET Core. We build REST and GraphQL APIs, background job processors, real-time services using SignalR, and Blazor applications that run server-side or entirely in the browser via WebAssembly.
Frontend Frameworks
On the frontend we work with Angular, React, and Vue.js, choosing the right framework based on your project's complexity, your team's existing codebase, and long-term maintenance needs. We do not push a preferred framework onto clients for its own sake.
Databases
We work with SQL Server and PostgreSQL as primary relational databases, and use Redis, MongoDB, and Elasticsearch where the data model warrants it. We design schemas with query performance and future migration costs in mind.
Cloud and Infrastructure
We deploy to Azure and AWS, using managed services where they reduce operational overhead and custom configurations where control matters more. We write infrastructure as code using Terraform and Bicep, and build CI/CD pipelines from day one rather than as an afterthought.
How We Work: A Process Built Around Transparency
Good bespoke software development requires more than technical skill. It requires a working process that keeps clients informed, catches problems early, and produces shippable software at regular intervals. Here is how we run engagements.
Discovery and Architecture
Every project starts with a structured discovery phase. We map your requirements, identify risks, define the data model, and produce an architecture document that the whole team works from. This phase typically takes one to three weeks and produces a clear, costed plan before development begins.
Iterative Development
We work in two-week sprints. At the end of each sprint, you receive a working demo of what was built. You give feedback, we adjust the backlog, and the next sprint begins. There are no six-month gaps between updates.
Testing
Quality assurance runs in parallel with development, not after it. We write unit and integration tests as part of normal development work. Dedicated QA engineers handle functional, regression, and performance testing on a scheduled basis throughout the project.
Deployment and Ongoing Support
We handle production deployment and remain available for post-launch support. Many clients retain us on a maintenance and feature-development basis after the initial build, which works well because the team that built the system already understands it deeply.
Why Choose DevIT Group as Your Custom Software Development Company
There are hundreds of software development agencies. Here is what makes DevIT Group a different option in practical terms.
Senior Engineers, Not a Junior Rotation
Many outsourcing firms staff projects with junior developers overseen by a senior who is spread across multiple accounts. At DevIT Group, senior engineers do the hands-on work. The people writing your code have between 8 and 20 years of professional experience. You are not paying for training on your budget.
UK-Registered, Eastern European Team
We are registered in the United Kingdom, which means clear contracts, UK-standard business practices, and no ambiguity about legal jurisdiction. Our engineering team is based across Ukraine, Poland, Azerbaijan, and Bulgaria. This structure gives clients the protection of a UK company combined with the competitive rates that Eastern European talent markets make possible.
Rates That Make Projects Viable
Our rates run from $22 to $30 per hour for most roles. Compare that to $100 to $200 per hour for US-based agencies or £40 to £120 per hour for UK-based developers. For a 6-month, 1,000-hour project, the difference between our rate and a UK freelancer's mid-range rate can exceed £70,000. That difference often determines whether a project gets funded at all.
Direct Communication and IP Ownership
You communicate directly with the engineers building your product. There is no account manager layer obscuring what is actually happening. All intellectual property transfers to you on final payment. The code, the architecture, the documentation: it all becomes yours.
Industries We Serve
We have delivered custom software development projects across a range of sectors. Each industry has distinct compliance requirements, data sensitivity considerations, and user expectations. Our team has built for:
-
Fintech: payment platforms, transaction monitoring tools, regulatory reporting systems
-
Logistics: route optimisation, fleet tracking, warehouse management integrations
-
Industrial and Engineering: operator control systems, equipment monitoring, safety-critical dashboards
-
Healthcare: patient data portals, clinical workflow tools, HL7/FHIR integrations
-
EdTech: learning management systems, assessment platforms, content delivery tools
-
Business Automation: document processing, ERP connectors, workflow orchestration
Case Study: AI Operator Dashboard for Swiss Ropeway Safety
One of our most technically demanding projects was an AI-powered monitoring dashboard for ropeway operations in Switzerland. The system uses computer vision and sensor data to monitor cabin loads, rope tension, and environmental conditions in real time. The result was a measurable operational improvement: the site reduced its required operator headcount from two to one without compromising safety margins. The dashboard processes live video feeds, flags anomalies, and presents a single operator with everything needed to manage the system safely and confidently.
Case Study: Antidetect Browser SaaS Product
We designed and built a commercial antidetect browser platform from scratch. The product allows users to manage multiple browser profiles with isolated fingerprints, cookies, and proxies. It includes a subscription management system, a team collaboration layer, and a web-based management console. The project required deep knowledge of browser internals, Chromium customisation, and multi-tenant SaaS architecture. We delivered it on schedule and it has been in active commercial use since launch.
Pricing for Custom Software Development Projects
We scope projects individually because fixed-price guesses made before discovery are rarely accurate for either side. That said, here are realistic budget ranges based on our completed projects.
MVP Build: $15,000 to $40,000
A focused MVP with core functionality, basic user authentication, and a production deployment. Suitable for validating a new product idea or replacing a specific internal process. Typically 8 to 14 weeks.
Mid-Complexity Project: $40,000 to $150,000
A full-featured product with multiple user roles, third-party integrations, background processing, and a polished UI. This range covers most commercial web applications and internal business systems. Typically 4 to 9 months.
Enterprise and Complex Platforms: $150,000 and above
Large-scale SaaS platforms, multi-tenant systems, AI-integrated products, or projects with significant compliance and security requirements. Timelines and team sizes vary based on scope.
Hourly Rate Engagements
For ongoing development, maintenance, or team augmentation, our standard rate runs from $22 to $30 per hour depending on role seniority and engagement structure. We can discuss retainer arrangements for clients with continuous development needs.
Frequently Asked Questions
How do we start a project with DevIT Group?
Book a 30-minute call via our Calendly link. We will ask you to describe the problem you are solving, any existing systems involved, and your timeline. After the call, we prepare a brief proposal and, if the fit looks right, we move into a paid discovery phase to produce a full architecture plan and cost breakdown.
Do you work with clients who already have an internal development team?
Yes. We regularly work alongside internal teams, either filling specific skill gaps (.NET, frontend, DevOps) or taking on self-contained modules while the client team handles other parts of the product. We adapt to your working environment, including your version control, ticketing, and communication tools.
Who owns the code and intellectual property once the project is complete?
You do. Full IP ownership transfers to the client on final payment. This is written into every contract. We retain no rights to the code, the architecture, or the product built on it.
How do you handle project communication across time zones?
Our Eastern European team operates on CET/EET time zones, which overlaps with UK business hours by 2 to 3 hours. We schedule daily standups or twice-weekly check-ins during that overlap window. All written communication happens in Slack or Teams, and we keep detailed sprint notes so nothing depends on memory from a single call.
Can you work with a fixed budget rather than time and materials?
Fixed-price contracts work well for clearly scoped projects where the requirements are stable and fully defined before development begins. After the discovery phase, we can offer a fixed price for the agreed scope. For projects where scope may evolve, time-and-materials with a capped monthly budget often produces better outcomes for both sides.
What makes DevIT Group different from other bespoke software development companies?
Three things stand out consistently in client feedback. First, the seniority of the engineers doing the actual work. Second, the rate structure, which makes projects viable that UK-only teams would price out of reach. Third, the directness of communication: clients talk to the people writing the code, not to an intermediary who translates requirements and relays feedback. Those three factors together produce faster, better outcomes on realistic budgets.
