Custom Software Development

Custom software development makes sense when off-the-shelf products do not solve the task. Usually it is one of three situations.

• The company’s processes are unique. A standard CRM or accounting system forces people to adapt to it, and half of the work ends up in spreadsheets and messengers.
• Data lives in different systems. Requests are in one program, accounting in another, and reports are assembled by hand. You need a system that ties everything into one process.
• You need a new digital product. A service for customers or partners that does not exist on the market yet, and the idea has to be tested fast.

We build custom software for these tasks: corporate systems and portals, CRM for a specific sales process, tracking and accounting systems, personal accounts for customers and partners, internal automation services and MVPs of new products.

TrackIT is an IT equipment tracking system: an equipment register, movement tracking, request automation, inventory support, document flow and reports.

ModulePlatform is a web platform for architectural design: building parameters, flat types, calculation of areas and costs, layout generation and source data for engineering.

IntraLink is a corporate portal with personal accounts, IT support, an office map, the org chart and HR features in its mobile version.

You can find more about each of them in the projects block below and in the Portfolio section.

We run the project from analysis to launch and support. The cards above show the main stages; here is what is behind them.

Requirements analysis

We study the process the system has to support: who takes part in it, what data is created and where it goes, where time is lost today. The result is the business requirements and a technical specification describing features, roles, integrations and non-functional requirements: security, load and availability.

Architecture

We design the system so that it is easy to develop further: we separate modules, think through the data model and API, choose where data is stored and how the system will scale. Good architecture is cheaper in the long run than any optimisation later.

Development and testing

We write the back end in Python and FastAPI, interfaces with modern web technologies, and a Flutter mobile app when needed. We work in two-week iterations and demo the finished part at the end of each. Features, integrations and load are tested before launch.

Integration with your systems

We connect the new system to what already works in the company: the website, accounting systems, CRM, telephony, email, messengers and payment services. We use REST API and GraphQL, and when an external system has no convenient API, we find a reliable way to exchange data.

Deployment and launch

We prepare servers or the cloud, package the system in Docker and use Kubernetes when the load grows. We set up automatic builds and releases, so updates ship without downtime.

Support and growth

After launch we look after the system: monitor stability, fix bugs under the 6-month warranty and develop features according to plan.

1. Consultation (1–3 days): we discuss goals, processes and constraints.
2. Business requirements and design mockups (3–5 days).
3. Technical specification (3–5 days): features, architecture, integrations.
4. Three development iterations (10–14 days each) with a demo after each.
5. Testing and refinement (7–10 days): functional, unit and load testing.
6. Launch and handover (3–5 days).

A report and a demo every two weeks make it easy to change priorities in time: if it turns out during the project that another feature matters more, the plan is adjusted right away.

We do not push you to build everything from scratch. If a ready product solves the task, it is usually faster and cheaper, and we will say so. Custom software is justified when:

• the process gives the company a competitive edge and should not adapt to someone else’s logic;
• customising and integrating a boxed solution costs about as much as your own system;
• licences for every employee cost more than owning your own solution;
• data and logic must stay inside the company, on its servers.

A mixed approach often makes sense: ready services for standard tasks and your own system that ties them into one process.

If you are launching a new product, start with an MVP, the minimal version that solves the user’s main problem. We release an MVP in 2–3 months: enough to get the first users, data and feedback. We design the MVP architecture for growth, so the next versions add features instead of rewriting the product. For example, the first version of a tracking system may include an asset register, an asset card with change history and a simple report, while approvals, accounting integrations and analytics come in the next iterations, when employees already work in the system and it is clear what they really need.

• The number of processes and roles: each role means its own screens, access rights and scenarios.
• Integrations: data exchange with accounting systems, CRM, the website and other services.
• Security requirements: access control, audit logs, storage of personal data.
• Load and availability: the number of users and records, fault tolerance requirements.
• The scope of the first version: an MVP or the full system at once.

The table above gives typical ranges. We use AI tools for routine code and tests, so timelines and costs are lower than with fully manual work, while quality is checked by the same testing stages.

A corporate system runs for years, so some things are cheaper to plan from the start than to add later.

• Access control. Roles and permissions are set up so that each employee sees and changes only their own data, and actions on important records are logged.
• Personal data protection. If the system stores customer or employee data, we design storage and access to meet personal data law and the rules of your security team.
• Backups and recovery. We set up regular database backups and check that a backup can actually be restored.
• Observability. Logs and metrics show what is happening in the system, so bugs are found from data rather than from user complaints.
• Documentation. We describe the architecture, API and deployment procedure, so the system can be developed by your team or any other contractor.
• Automated tests. Key scenarios are covered by tests, so new features do not break old ones.

All of this is part of the project estimate, not an extra: without these properties a system quickly becomes expensive to maintain.

• Back end: Python, FastAPI, PostgreSQL, MongoDB, SQLite, REST API and GraphQL.
• Interfaces: web applications and, when needed, Flutter mobile apps.
• Infrastructure: Docker, Kubernetes, deployment on your servers or in the cloud.

• One team for the whole system: analysis, design, back end, interfaces, integrations and launch.
• Transparency: a report and a demo every two weeks.
• 6-month warranty on our work.
• Free start: we study the task and propose a solution with an estimate before the contract is signed.

Describe your task in the form below, and we will suggest an approach, the scope of the first version and an estimate of time and cost.
