SOFTWARE SYSTEMS

SOFTWAREWeb applications and SaaS.
Built as scalable systems.

We design and engineer multi-user web applications and subscription platforms — with defined system architecture, data models and long-term operational stability.

Software as structured infrastructure.

A SaaS product is not just functionality. It is a system of roles, data layers, permissions and operational logic.

System capabilities.

Multi-user web applications

Role-aware applications with explicit access boundaries, stable data structures and maintainable domain logic.

Subscription SaaS platforms

Subscription systems with account lifecycle, billing architecture and infrastructure prepared for operational growth.

Admin & operational dashboards

Control interfaces for internal teams with policy-aware actions, audit visibility and reporting consistency.

Internal workflow systems

Automation-focused systems replacing fragmented manual processes with structured process orchestration.

Client portals

Secure client-facing layers connecting account data, requests and operational interactions without exposing internal tools.

Data & reporting platforms

Governed reporting systems that connect pipelines, business metrics and decision-critical operational data.

Defined before development.

Role & access control

Authorization is defined at domain level, not as a UI patch during late development.

Tenant isolation (multi-tenancy)

Tenant boundaries are designed for security, compliance and clear operational separation.

Modular system design

Feature domains are separated to support maintainability, iterative releases and long-term scalability.

API-first contracts

Interfaces are defined before implementation, enabling predictable integration and system evolution.

Background processing & queues

Asynchronous operations are isolated from user interaction paths for stability and performance.

Monitoring & logging

Operational observability is embedded from day one to support reliability at scale.

Revenue logic built into architecture.

Subscription tiers

Plan boundaries and entitlement logic are implemented as core architectural rules.

Usage-based billing

Metering and billing thresholds are integrated into domain logic and reporting.

Freemium models

Access segmentation and upgrade pathways are designed directly into product behaviour.

Enterprise contracts

Contract-specific requirements are reflected in provisioning, permissions and support structures.

White-label structures

Multi-brand deployment capabilities are implemented through tenant-level configuration layers.

From idea to scalable product.

01

Product & system strategy

Scope, system boundaries and decision criteria are defined before implementation.

02

Architecture & UX definition

System contracts and interface logic are structured together as one product layer.

03

MVP engineering

Core workflows are delivered on production-ready foundations with measurable technical quality.

04

Scaling & optimisation

Performance, reliability and operational efficiency are improved through structured iteration.

Investment aligned with system complexity.

Web application

From €12,000

Structured product build with core workflows, role logic and integrated data model.

SaaS platform

From €18,000

Subscription-ready platform architecture with operational tooling and billing integration.

Complex multi-tenant system

From €30,000

High-complexity architecture with tenant isolation, policy layers and scaling infrastructure.

Common questions.

What is the difference between a website and a web application?

A website primarily presents information. A web application executes business logic through user roles, permissions and stateful data.

Do you build multi-tenant SaaS systems?

Yes. Tenant separation, policy design and operational control are part of our core SaaS architecture work.

Can you integrate payments and subscriptions?

Yes. Subscription lifecycle, billing logic and payment integrations are implemented at system level.

How long does development take?

Typical delivery ranges from 10 to 20 weeks depending on scope, integrations and product complexity.

Can you migrate an existing product?

Yes. We manage migration strategy, data mapping and phased transition plans with continuity in mind.

Do you offer long-term technical support?

Yes. We provide structured post-launch support for maintenance, optimisation and controlled product evolution.
