Secure Self-Service for Your Clients

We design and build bespoke customer portals for businesses across the UK and Isle of Man. A well-built customer portal gives your clients secure, self-service access to their accounts, documents, orders, bookings, or support - reducing inbound contact, improving client satisfaction, and freeing your team from manual update requests.

Off-the-shelf portal solutions are built for generic client relationships. If your clients have specific data they need to access, specific actions they need to perform, or specific workflows that need to be reflected in the portal experience, a bespoke build gives you full control over what they see and how they interact with your business.

Every portal we build is designed and delivered personally by Owen Jones, OLXR's founder and lead engineer. We connect your portal directly to your existing back-office systems, databases, and tools - so your clients always see accurate, live information, and your team is not manually keeping two systems in sync.

Our Approach

Map Both Sides of the Relationship

Customer portals sit at the intersection of your internal systems and your client relationships, so we start by understanding both sides. What do your clients actually need from a portal - and what does your team need to manage it effectively? Those two sets of requirements do not always align with what a product owner initially assumes, and the gap between them is where most portal projects go wrong. We map both before proposing anything.

Connect to Your Existing Data

A portal that sits in isolation from your back-office systems creates more work, not less. Your team ends up manually keeping two systems in sync, and your clients see stale or inaccurate data. We build portals that connect directly to your existing data sources - whether that is a CRM, an ERP, a bespoke internal system, or a database - so the information your clients see is always live and accurate without any manual intervention.

Build for the Client Experience

The success of a customer portal is measured by whether your clients actually use it. We design portal interfaces around real client workflows - not internal system logic - so the experience feels intuitive rather than like a window into your back-office. Adoption comes from usefulness, and usefulness comes from understanding how your clients actually want to interact with your business.

Why Choose OLXR

Most portal projects fail not because of technical complexity but because the requirements were gathered from the wrong people. We talk to both your internal team and, where possible, your clients before designing anything - because the portal that your operations manager imagines is rarely the same as the portal your clients would actually use.

Frequently Asked Questions

Yes - integration with existing systems is almost always a core requirement for customer portals, and it is something we specialise in. We connect portals to CRMs, ERPs, finance tools, HR platforms, and bespoke internal databases. Even older legacy systems without modern APIs can typically be connected through database-level integrations, file-based workflows, or custom adapter layers.

Security is built into the architecture from day one, not added afterwards. We implement role-based access control, encrypted data transmission, secure authentication using modern standards, session management, and full audit logging as standard. For regulated industries we can also support specific compliance requirements around data retention, access trails, and data residency.

Yes - secure file upload, storage, versioning, and access control is a common portal feature that we handle as standard. We implement secure file storage on AWS S3 or Azure Blob Storage, with access controls that ensure clients can only access their own files. We can also add virus scanning, file type validation, and size limits as required.

Yes - role-based and account-based access control is fundamental to how we build portals. Different clients can have different data views, different available actions, and different permission levels. We design the access control model with you during the planning phase and implement it at both the application and database layer.

It depends on the complexity of the portal and the number of integrations required. A focused portal with a clear feature set and one or two integrations can typically be delivered in 8-12 weeks. More complex portals with multiple system integrations, custom workflows, and advanced access control typically take 3-5 months. We will give you a realistic timeline after understanding your specific requirements.
