Why It Matters

Fast Websites Win. Slow Ones Lose Revenue Every Day.

A 1-second delay in page load costs an average e-commerce site 7% of conversions. We build with performance budgets, CDN delivery, and lazy-loading as defaults โ€” not afterthoughts.

Every site we launch comes with source code ownership, a staging environment, full documentation, and a post-launch support window โ€” so you're never left with a black box.

Why Advento

The Web Dev Partner Built for Indian Businesses

๐Ÿ‡ฎ๐Ÿ‡ณ

Optimised for India's Web Reality

We build for low-bandwidth users, regional language audiences, UPI-first payment flows, and GST-compliant invoicing โ€” considerations that generic overseas agencies routinely miss.

๐Ÿ”

SEO Built In From Day One

Technical SEO isn't added after launch โ€” it's baked into our architecture. Clean URLs, structured data, Core Web Vitals, canonical tags, and XML sitemaps are standard on every project.

๐Ÿ”‘

100% IP & Code Ownership

Every line of code, every design file, and every database schema belongs to you. We hand over complete repositories, Figma files, and documentation โ€” no lock-in, no ongoing licensing fees.

๐Ÿ“

Design + Dev Under One Roof

Our designers and engineers work together from brief to launch โ€” no handoff delays, no "the dev changed my design" frustrations, and no hidden revision charges. One team, one accountability.

FAQ

Common Web Development Questions

A professional marketing website typically costs โ‚น80Kโ€“3L depending on number of pages, design complexity, CMS requirements, and integrations. A custom web app or SaaS platform ranges from โ‚น3L to โ‚น25L+. We provide a detailed, line-item quote after a free discovery call โ€” no surprises.
It depends on your goals. WordPress or Webflow suits content-heavy sites where non-technical editors need control. Shopify is ideal for straightforward e-commerce. Custom Next.js or React builds are right when you need unique functionality, high performance, or a web app with complex business logic. We help you choose the right approach โ€” not the most expensive one.
A marketing website takes 3โ€“6 weeks from kickoff to launch. A full e-commerce store takes 6โ€“10 weeks. A custom web app or SaaS platform takes 10โ€“20 weeks. We provide milestone-based timelines in our project blueprint so you always know what's being delivered each week.
We build every website with technical SEO as a foundation โ€” clean URL structures, schema markup, sitemap generation, Core Web Vitals optimisation, and canonical tags are all standard. We also provide keyword-focused content architecture and Search Console setup. Organic ranking growth takes time, but our sites are built to be found from day one.
Yes โ€” every project includes 3 months of post-launch support covering bug fixes, browser compatibility updates, and minor content changes. After that, we offer monthly retainer plans for ongoing development, SEO improvements, and performance monitoring. You'll never be left with a site and no one to call.
