Custom Software Engineering, built around your business logic.
Stop compromising with rigid generic SaaS and legacy bottlenecks. We engineer robust, scalable, and business-critical software solutions with 100% code and data ownership.
When Generic Software Can No Longer Keep Up
As companies scale, the limitations of generic one-size-fits-all software become major bottlenecks. Workflows are bent to match rigid templates, integration gaps require manual spreadsheet glue, and per-seat license costs escalate uncontrollably.
Custom software engineering with Alegor delivers complete operational freedom. We engineer systems aligned precisely with your processes. Powered by our modular Alegor Engine foundation, you never pay to reinvent standard boilerplate—you receive hardened enterprise architecture from day one while focusing 100% on your competitive edge.
Generic Software vs Custom Engineering
You are forced to work around vendor constraints, penalized by escalating per-user fees, and blocked from quickly launching new strategic business capabilities.
Engineered entirely around your competitive advantages, leveraging pre-built architectural modules for auth, data, and integrations for maximum velocity and stability.

What Drives the Scope & Investment in Custom Software?
Software development investment depends on system breadth, third-party integrations, and migration complexity. We provide clear fixed-scope milestones.
Functional Scope & Complexity
The difference between a focused client portal and an enterprise operational platform featuring complex real-time business logic.
Integration Depth & APIs
The number and nature of external services connected (accounting systems, payment providers, BankID, CRMs, or IoT devices).
Legacy Data Migration
The volume and cleanliness of historical records requiring sanitization, transformation, and reconciliation into the new database.
Security & Compliance Needs
Requirements for electronic identification (BankID), granular RBAC permission layers, and strict audit logging under GDPR standards.
Frequently Asked Questions about Custom Development
How does custom software engineering differ from generic SaaS tools?
Off-the-shelf software forces you to alter internal processes to fit rigid software constraints, along with increasing per-seat monthly license fees. Custom software is 100% aligned with your business model, giving you maximum efficiency, competitive differentiation, and complete ownership of code and data.
Who owns the intellectual property and source code?
You retain 100% ownership of your customized source code, database architecture, and proprietary business data. There is zero vendor lock-in.
What is the Alegor Engine and how does it reduce cost and delivery time?
Alegor Engine is our battle-tested library of architectural foundation modules covering authentication, multi-tenancy, RBAC, background jobs, and integrations. Reusing these rock-solid components means you never pay to build standard boilerplate from scratch, accelerating time-to-market.
How do you handle enterprise security and GDPR compliance?
We engineer with Security and Data Protection by Design: end-to-end encryption in transit and at rest, fine-grained RBAC permissions, and immutable audit logs hosted on Swedish/EU cloud infrastructure.
How do ongoing support, SLAs, and maintenance work post-launch?
We offer proactive maintenance and SLA agreements covering 24/7 telemetry monitoring, dependency upgrades, bug fixes, and continuous feature development as your organization grows.
What is the typical timeframe for engineering a custom system?
An operational Minimum Viable Product (MVP) covering your core business logic is typically deployed within 6–10 weeks, followed by iterative additions in transparent agile sprints.
