Book a CallCustom Portal Development
Custom client, customer, and partner portal development from BlockLabs — secure authentication, dashboards, and integrations built to your exact spec.
A portal is where your customers, partners or staff interact with your business day to day — so it needs to be fast, secure and built around real workflows. We develop custom client portals, customer self-service portals and internal platforms with the parts that matter done properly: authentication and access control, role-based permissions, dashboards, document handling, notifications and clean API integrations with your back-end systems. We build portals that hold up under real usage and are straightforward to extend later.

Frequently asked questions
How much does a custom portal cost?
Portal builds vary with the number of roles, integrations, and dashboards involved, so we scope and price each one individually — but like all our engagements, it's a fixed price agreed after a discovery call, starting from €25,000 for a focused build.
How long does a portal build take?
A focused portal — one user type, core dashboards, a handful of integrations — typically takes 2–4 weeks. A multi-role platform with deeper integrations and permissioning runs 8–16 weeks, delivered in weekly working releases.
What's the engagement model?
Fixed scope and fixed price, locked before development starts. Senior engineers only, with a weekly demo so you're reviewing working software throughout, not waiting for a single big reveal at the end.
Who owns the portal and its code once it's built?
You do. Full ownership of the codebase and intellectual property transfers to you on final payment, along with documentation and a structured handover.
Do you build in compliance and access controls, or is that extra?
It's standard. Role-based permissions, an audit trail of who accessed or changed what, and GDPR-compliant data handling are built into every portal from the start, since portals routinely handle personal and commercially sensitive data.
