Custom software development company in London: what affects the price?

It depends on the scope of the project, the number of users and links to existing systems. After analysis you get a written estimate, with no templates and no monthly platform licences.

Custom software development company in London: what do I get?

An analysis of your situation, a written estimate and a build plan. The engineer who replies to you builds it, and the code and access stay yours.

Where are you based, and do you work with companies in London?

We are based in Split, Croatia (Peričićeva 14). We work with companies in London in writing, the same way for every city: you describe the project in the form, and the engineer who will build it replies.

Can you develop an intranet portal for our employees?

Yes. We build intranet portals for companies with 50–500 employees, including document management with version control, onboarding modules, HR self-service dashboards, task management, and internal communication channels. Portals are hosted on your servers or private cloud for full data sovereignty. Every portal includes full-text search, mobile-responsive design for field staff, and role-based access control ensuring each department sees only information relevant to their function.

Do you support Single Sign-On (SSO) integration?

Yes, we implement SSO with all major identity providers: Microsoft Azure AD (Entra ID), Google Workspace, Okta, Auth0, and custom SAML 2.0 or OAuth 2.0 solutions. SSO provides secure access across all business systems with a single set of credentials, eliminating password fatigue and reducing IT support tickets. For enterprises requiring advanced security, we implement multi-factor authentication (MFA) and conditional access policies based on device, location, and risk signals.

Do you work with public institutions and EU-funded projects?

Yes. We build software for EU-funded projects and can assist with technical documentation for EU tenders, including ESF+ (European Social Fund), ERDF (European Regional Development Fund), and Horizon Europe programmes. Our solutions satisfy EU eligibility requirements for digital transformation grants: GDPR compliance, accessibility standards (WCAG 2.2), and documentation in the format auditors expect. Our EU jurisdiction simplifies procurement compliance.

How secure is your software for business data?

We apply layered security: HTTPS/TLS 1.3 encryption in transit, AES-256 at rest, Role-Based Access Control (RBAC) with granular permissions, independent penetration testing on request, automated daily backups with point-in-time recovery, and real-time monitoring with anomaly alerting. For businesses handling sensitive data (financial records, HR data, trade secrets), on-premise deployment with no shared tenancy is available. All systems are GDPR-compliant from the ground up.

Enterprise Software & Systems Integration

We connect the systems you already run (ERP, CRM, internal tools) so nobody re-types the same data across five different screens.

Outcomes

Less administrative work, with one source of truth for every department: no more duplicate data entry. AI automation handles the repetitive cognitive work, not just the data entry.

Process

We start with a digital audit, which usually finds quick wins before any custom build. Ask for that first, before committing to a bigger project.

Businesses & Institutions in London: how we work

For companies in London we build to spec: no templates, no monthly licences, and the code, repository and access are yours from day one. In London, much of the demand comes from Fintech & Banking, so every project is built around high-compliance security.

London is one of Europe's largest fintech hubs, with a regulatory environment that shapes how high-compliance digital infrastructure is built. Businesses operating here expect technical partners who understand both the pace of product work and the weight of regulatory obligation, building for FCA standards, GDPR and multi-market scale from day one.

London concentrates a dense mix of regulated financial and professional-services firms. Here, custom software usually replaces a patchwork of spreadsheets and compliance trackers with a single system that gives leadership real-time visibility.
