Modern Solutions Tailored to Your Workflows
In Wales' leading commercial and public sector hub, staying competitive requires efficient workflows and a polished customer experience. For a local retail brand, off-the-shelf systems can feel rigid, offering a subpar experience and expensive licensing. A bespoke custom client portal built specifically around your operations offers the security, flexibility, and performance required to grow.
At Els Labs, we specialize in helping retail & e-commerce brands in Cardiff bridge the gap between their customer-facing brand and internal databases. One of the most common dilemmas business owners face is whether they need a custom-built custom client portal integrated with their existing website, or a brand-new, independent platform. Off-the-shelf software solutions often force your team to adjust to their pre-set workflows. With a bespoke solution, the software adapts completely to you — automating coordinating bulk commercial wholesale buyers, setting trade discounts, and integrating stock tracking with ERP systems.
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 retail & e-commerce brands 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.
We build using React, Next.js, and TypeScript, backed by secure, relational databases like PostgreSQL. Because we do not rely on bulky, outdated web platforms, our code is lightweight, extremely secure against hacking, and does not require monthly per-user licensing fees. You own the code and the customer data. By choosing a custom build, you ensure that your wholesale portal scales alongside your business without unexpected costs, while providing your Cardiff clientele with a world-class customer area they will love to use.
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
- Supports existing user databases
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
- Statically generated pages for peak search engines performance
