Frequently Asked Questions

Websirus is a premium web development agency based in the UK. We build custom web applications, e-commerce platforms, SaaS products, and UI/UX designs for ambitious businesses that want to stand out online.

We are based in the United Kingdom and work with clients across the UK and internationally. We serve businesses in London, Manchester, Birmingham, Edinburgh, Leeds, Bristol, Glasgow, and beyond.

We work with both. Whether you are a startup launching your first MVP or an established business looking to rebuild your digital presence, we tailor our approach to your stage and budget.

Start by filling out our Project Architect form on the Contact page. It takes about 2 minutes and helps us understand your requirements. We typically respond within 24 hours with a tailored proposal.

Yes. We offer post-launch support packages that include bug fixes, performance monitoring, security updates, and feature additions. We want your project to succeed long after launch day.

Absolutely. Visit our Work page to see detailed case studies including Showleys (private chef booking), Arte Lusso (luxury marketplace), VineSage (wine investment platform), and more.

Our core stack includes Next.js, React, TypeScript, and Node.js. For e-commerce we use Shopify (headless) and for databases we work with PostgreSQL, Supabase, and MongoDB. We choose the best tools for each specific project.

We specialise in web applications, but our sites are fully responsive and work beautifully on all devices. For native mobile apps, we can recommend trusted partners or build progressive web apps (PWAs) that feel native.

Yes. We frequently take existing websites and rebuild them with modern technology, better performance, and improved user experience. We will audit your current site and propose a migration strategy.

We deploy projects to modern platforms like Vercel, AWS, or Cloudflare depending on your requirements. We handle the deployment and can manage hosting on your behalf as part of a support package.

Headless e-commerce separates the storefront (what customers see) from the backend (inventory, orders, payments). This gives you complete design freedom and significantly better performance compared to traditional Shopify themes.

Every site we build is SEO-optimised by default: proper meta tags, structured data, fast load times, mobile responsiveness, and semantic HTML. We also offer technical SEO audits and ongoing optimisation.

Our process has four stages: Discovery (understanding your goals and requirements), Design (wireframes, UI design, prototyping), Development (building with modern tech, iterative reviews), and Launch (testing, deployment, handover). Each stage includes client checkpoints.

Simple marketing sites take 2-4 weeks. Custom web applications and e-commerce builds typically take 6-12 weeks. Complex SaaS products can take 3-6 months. We provide a detailed timeline in our proposal.

We use a combination of email, video calls, and project management tools. You will receive regular updates and have direct access to your developer. We believe in transparent, responsive communication.

Yes, 100%. Once the project is complete and paid for, you own all the code, designs, and assets. We provide full source code access and documentation for handover.

Yes. Our design phase includes revision rounds to ensure the final product matches your vision. During development, we do iterative reviews so changes are caught early rather than at the end.

Projects start from around £2,500 for marketing sites and go up to £25,000+ for complex SaaS applications. We provide detailed, transparent quotes based on your specific requirements. No hidden fees.

Yes, we typically require a 30% deposit to begin work, with the remainder split across milestones. This protects both parties and ensures steady progress throughout the project.

Yes. For larger projects, we can structure payments across 2-4 milestones aligned with project deliverables. We are flexible and happy to discuss payment arrangements that work for you.

Our quotes include design, development, testing, deployment, and a handover session. They also include responsive design, basic SEO setup, and a bug-fix warranty period after launch.

The development itself is a one-time cost. Recurring costs are hosting (typically £5-50/month depending on platform) and any optional ongoing support packages. We are transparent about all costs upfront.

Next.js provides server-side rendering for better SEO, static generation for blazing-fast load times, and a great developer experience. It powers some of the biggest sites on the web and is backed by Vercel.

Performance is a core priority. We target 90+ Lighthouse scores across all metrics. Our sites use modern techniques like code splitting, image optimisation, edge caching, and minimal JavaScript to ensure fast load times.

Yes. We follow OWASP security best practices, use HTTPS everywhere, implement proper input validation, and keep dependencies updated. For authentication, we use battle-tested solutions like Supabase Auth or NextAuth.

Every site we build is fully responsive and tested across desktop, tablet, and mobile devices. We also test in multiple browsers (Chrome, Firefox, Safari, Edge) to ensure consistent experience.

Yes. We regularly integrate with payment processors (Stripe, PayPal), CRMs (HubSpot, Salesforce), email services (Resend, SendGrid), analytics (GA4, Plausible), and many other APIs.

Where it adds genuine value, yes. We integrate AI capabilities using the Anthropic Claude API for features like intelligent chatbots, content analysis, and smart form processing. We never add AI for the sake of it.
