Client-centred design
We design portals from the user's perspective: intuitive, accessible and recognisable as your brand. Including for non-technical end users.
Secure on Google Cloud
Each client sees only their own data. Login via Google or Microsoft accounts is supported out of the box. Hosted in Europe, fully GDPR-compliant.
Web and mobile
Angular for complex web portals, Flutter for mobile client apps, NestJS backend for both.
What is a customer portal?
A customer portal is a secure online environment where your customers, members or partners have access to information, services or functionality designed specifically for them. They log in with their own account and only see what is relevant to them.
Examples of customer portals we build:

Security and access
We host customer portals by default on Google Cloud Run: GDPR-compliant in Europe, automatically scalable and nothing for you to manage. Customers log in via their own account system or via Single Sign-On (SSO) using existing credentials such as Google or Microsoft. Access is role-based: every user sees only what is intended for them.
Web or mobile?
The right technology choice depends on how your clients use the portal.
Need a purely internal portal for employees? See our web application development page.

Veelgestelde vragen
A regular website is public and shows the same content to everyone. A customer portal is secured: visitors log in with their own account and only see the content and functionality intended for them. Think personal invoices, their own reservations or member-exclusive content.
A portal also has interactive capabilities that a static website does not: booking, ordering, filling in forms, uploading documents or making payments.
Yes. We have extensive experience integrating portals with existing business software via APIs. Customer data, invoices or contracts already in your CRM or ERP can be visible in real time in the portal. Integrations with payment providers, email platforms or accounting packages are also possible.
We build customer portals with role-based access control: every user only sees what is intended for them. Login can be via a dedicated account system or via SSO using Google, Microsoft or other identity providers.
Hosting is on Google Cloud Run in European data centres (Frankfurt). Data is encrypted in transit and at rest, and the environment meets GDPR requirements. For portals handling particularly sensitive personal data, we add additional security layers.
It depends on how your clients use the portal. Primarily on a desktop or laptop: we build a web portal in Angular. Primarily on phone or tablet: a Flutter app is the better choice. Need both? We build a shared NestJS backend with both a web and mobile frontend, so clients can choose.
A simple portal with login functionality and a limited number of screens starts from €15,000. A fully-featured portal with multiple user roles, system integrations and a mobile app typically costs €30,000 to €60,000. See all pricing factors on our pricing page.
A simple portal can go live in 2 to 3 months. A fully-featured portal with multiple roles, integrations and a mobile app takes 4 to 6 months. The preparation phase — from first conversation to approved quote — typically takes 2 to 4 weeks.
We work in two-week rounds. After each round you receive a working version you can test immediately. That allows you to course-correct throughout the process.
After launch we handle maintenance: OS updates for the Flutter app, dependency upgrades for Angular and NestJS, security patches and further development. Each quarter we issue an advisory report. You decide what work to commission — no fixed contract, no obligation.
Let's grab a coffee. Tell us about your idea and we'll give you our honest take on what's possible.
