Modern Solutions Tailored to Your Workflows
For digital & creative agencies operating in Cardiff, standard off-the-shelf dashboards often restrict growth and create administrative bottlenecking. By investing in a custom custom client portal built to integrate with your existing website, you eliminate licensing bloat and deliver a frictionless digital experience to your UK clients.
Scaling a digital agency in Cardiff requires software that matches your custom processes. At Els Labs, we build custom client portals that fit your day-to-day requirements, eliminating the need to copy-paste data between separate systems. Whether you need to automate client onboarding or secure document transfers, our engineering team constructs an administrative portal that directly resolves handling client onboarding, asset gathering, and secure project tracking without massive email chains and spreadsheets.
Whether you want to connect a custom custom client portal securely to your existing CMS database via REST APIs, or launch a fully custom Next.js frontend on a dedicated subdomain, we have the technical experience to execute it. Based in the UK, Els Labs engineers every product for sub-second speeds, web accessibility (WCAG compliance), and search engine optimization. For digital & creative agencies in Cardiff, this means your clients enjoy a seamless user experience across mobile, tablet, and desktop, while your brand ranks organically at the top of Google search results.
Our modern development stack centers around React, Next.js, and TypeScript, with secure PostgreSQL data storage. This keeps the application load lightweight and resilient against common web vulnerabilities. Crucially, because you own the source code, you pay no ongoing user licensing fees. This bespoke agency portal scales dynamically as your transactions grow, securing your customer data and presenting a premium workspace tailored to Cardiff's commercial landscape.

Need a customer panel for your existing website, or a brand-new one?
We deliver flexible, API-driven architectures that fit your current digital infrastructure.
Option A: Add Panel to Your Existing Site
If you already have a functional marketing website (built on WordPress, Webflow, custom HTML, etc.) and want to add client areas, billing dashboards, or custom databases without rebuilding the front end, we construct a secure portal on a subdomain (e.g. portal.yourcompany.co.uk) and synchronize data securely via REST/GraphQL APIs.
- Preserves current SEO and design investment
- Connects securely via custom API microservices
- Role-based customer login gates

Option B: Build New Unified Website & Portal
For organizations ready to modernize their entire digital footprint. We build a unified Next.js application combining a beautiful, lightning-fast marketing website with a built-in user dashboard. This gives you a cohesive brand experience, incredible speed (100% Core Web Vitals score), and unmatched search engine ranking potential.
- Sub-second loading times via Next.js App Router
- Built-in, matching design language throughout
- Unified codebase for easy maintenance
