Inventh web development services build corporate websites, web applications, ecommerce stores and customer portals that load fast, meet WCAG 2.2 accessibility and pass Google’s Core Web Vitals. Every site includes technical SEO and structured data, so it is ready to rank and to be cited in AI answers.
Our approach
Your website is your hardest working salesperson. We build it that way.
Buyers judge a business by its website in seconds, and search engines and AI assistants judge it by its speed, structure and content. We engineer for the visitor, the search engine and the team who has to keep it current.
Fast everywhere
Performance budgets set at the start and tested on real mobile devices, so pages load quickly on any connection.
Easy to manage
Content management that lets your team publish and update pages without waiting for a developer.
Built on standards
Accessible, secure and search friendly by default, following WCAG, OWASP and search engine guidelines.

Performance
Core Web Vitals
Google's Core Web Vitals measure loading (LCP within 2.5 seconds), responsiveness (INP of 200 milliseconds or less) and visual stability (CLS of 0.1 or less). INP replaced FID in 2024.
Since June 28, 2025
European Accessibility Act
Many ecommerce and digital services sold to consumers in the EU must now be accessible. We build to WCAG 2.2 level AA, the current W3C accessibility standard.
Since March 31, 2025
PCI DSS 4.0.1 payment page rules
Online stores must inventory and authorize scripts on payment pages and detect unauthorized changes. We design checkout pages with these requirements in mind.
AI search
Indexable and snippet eligible
Google states that pages appear in AI Overviews and AI Mode when they are indexed and eligible for snippets, with no special files required. Clean technical SEO is the entry ticket.
Chrome origin trial
WebMCP for AI agents
WebMCP is a proposed web standard, in origin trial from Chrome 149, that lets websites expose structured tools such as search, booking and checkout to AI agents.
Mobile first
Google indexes the mobile version
Google crawls and ranks sites based on their mobile version, so every site we build is designed and tested mobile first.
When it makes sense
Signs your website needs attention
It is slow on mobile
Pages take seconds to load on a phone, fail Core Web Vitals and lose visitors before they see your offer.
Updates need a developer
Simple content changes wait in a queue because the site is hard to edit or built on an outdated theme.
You have outgrown the platform
Plugins, workarounds and manual processes hold the business back, and every new feature is a struggle.
It fails accessibility or security checks
Audits, customers or payment providers are raising accessibility, security or compliance concerns.

FAQ
Frequently asked questions
How much does a website or web application cost?
Cost depends on the number of pages, features, integrations and the platform. A corporate website costs far less than a custom web application or portal. After discovery you receive a written, itemized estimate.
How long does it take to build a website?
A corporate website typically takes several weeks, while ecommerce stores and web applications take a few months. You review progress on a staging site throughout.
Should we use WordPress or a custom build?
WordPress suits most corporate and marketing websites. A headless CMS suits content published across many channels, and a custom web application suits portals and business workflows. We recommend a platform after discovery.
Will our new website be fast and SEO friendly?
Yes. We build to Google's Core Web Vitals thresholds and include technical SEO, structured data and sitemaps from the start, so the site is ready to rank and to be cited in AI answers.
Can you redesign our website without losing search rankings?
Yes. We map every existing URL, set up permanent redirects, preserve content that ranks and monitor Search Console after launch.
Do you build accessible websites?
Yes. We build and test to WCAG 2.2 level AA, which supports compliance with laws such as the European Accessibility Act.
Which ecommerce platforms do you work with?
We build on Shopify, BigCommerce and WooCommerce, and build headless or custom commerce when a business needs more flexibility.
