Custom web development
When a template isn't enough, we build exactly the website your business needs – around your processes, your integrations and the way you work.
What custom web development is – and when you need it
Custom web development means designing and coding a website for one specific purpose, instead of bending your business to fit the limits of a template or a generic CMS. Every screen, form and process is shaped around what you and your users actually need.
It isn't always necessary: for many corporate websites, WordPress is more than enough. But when your site has to calculate quotes, manage bookings, give customers a private area or talk to your ERP, a bespoke build is more reliable, faster and, in the long run, cheaper than stacking up plugins.
OnClick has been building web projects from Vic for businesses in Barcelona and across Spain for 25 years. We listen, get to grips with your business and build a solution that's genuinely yours.
Custom web projects we develop

Private areas where your customers can check orders, invoices, documents or the status of their services.

Integrations
We connect your website to ERP and CRM systems, payment gateways, shipping services or third-party APIs to cut out manual work.
Configurators and calculators
Tools that let your customers customise a product or get a price instantly.
High-performance websites
Sites with heavy traffic or large amounts of content that need an optimised, scalable architecture.
Evolving existing sites
New features, refactoring or migrating legacy projects to modern technology.
The benefits of a bespoke website
A custom website does exactly what you need – nothing more, nothing less. That means a clearer experience for your users and fewer repetitive tasks for your team.
And because we also build custom software and our own ERP/CRM, Stratya®, we know how to make your website and your business systems share data seamlessly.
- Exactly the features you need, with no template limits
- Your own clean, documented code
- Better performance and fewer external dependencies
- Security by design, following ENS criteria
- Integration with your management systems
- Scalable: it grows at the pace of your business
