Film

Posts get attention. A website leads to contact.

The film in a few sentences
  • Posts get attention; a website shows your offer, your work and the way to reach you in one place.
  • Kvant Studio writes, designs and builds websites for companies and service businesses.
  • Before work starts, you get a proposal with the scope, price and timeline.
  • To request a quote, tell us what you do and what you want the site to achieve.

Example scope

What a website for a service business looks like.

For a business that lives on its services, such as a repair service, a salon or a contractor, the site usually has these pages:

  • Home: what you do, where you work and the fastest way for a customer to reach you.
  • Services: each main service clearly described, on its own page where needed, like the six service pages on the DolceVita by Irma site.
  • Work or gallery: finished jobs, for example before-and-after photos.
  • About: who is behind the business and why customers can trust you.
  • Contact: a call button, WhatsApp, Viber and a short form.

From you: service details, prices and answers to a few questions. We can use photos and video from your Instagram: the galleries for DolceVita by Irma and GroomerAna were built from photos on the salons' own profiles. We write or edit the copy; you approve it.

Read more

We design and build the site, and set up technical SEO, Search Console and analytics. For a local business, we also recommend a Google Business Profile linked to the site.

Agreed separately: extra languages, online booking or sales, editing the content yourself (CMS), maintenance and an SEO plan after launch. The exact pages and features, with the price and timeline, are in your proposal.

Your proposal

The price follows the scope of your site.

After a short exchange you get a proposal with the exact scope, price and timeline, before we start.

What shapes the scope and price

  • Which pages the site needs and the job of each
  • Who prepares the texts and photos: you, us or both
  • How many languages
  • Features and integrations, from booking to CRM
  • Whether you edit content yourself in a CMS
  • When the site has to be ready

How quotes work

  1. 1You send a few sentences about your business and what you need.
  2. 2We clarify the details, in writing or on a short call.
  3. 3You get a proposal with the exact scope, price and timeline.

What we guarantee in the contract

  • Lighthouse mobile Performance 95+ at handover for everything we code in Next.js, or we fix it for free.
  • The launch date is in the contract, and so is how much less you pay if the delay is on us.
  • For 30 days after launch we fix bugs for free.
  • You approve the design. Your proposal sets the number of revision rounds; extra changes and their price are agreed in writing first.
  • The total in your proposal covers the whole agreed scope.
  • The domain is registered in your name from day one. After the final payment, the code, design files and content belong to you. You choose who you work with next.

Outcomes

Clear offer. Simple contact.

A clear offer, measured speed and a short path to an inquiry.

Speed

Speed we measure

At handover, we test the site's mobile performance with Lighthouse and show you the score.

Leads

A simple way to inquire

Every page has one job and one next step: an offer people understand, prices where you want them, and a short form that lands in your inbox.

Ownership

Your domain, code and content

At handover, you receive the code, content and all login details. Host with us or anywhere else.

Custom vs template

Custom website vs template: what custom means.

“Custom” doesn't mean the same thing everywhere, so ask whether a design starts from your content or from a purchased theme. We mean a design made for your content and your customers, then coded by hand in Next.js. No theme, no page builder, and no plugin stack to keep updated.

Read more

The difference shows up in three places: how fast the site loads on a mid-range phone, how easily Google understands it, and what it costs to change two years from now.

Templates have their place. If you need a page up this week on a shoestring budget, a theme is the honest answer, and we'll tell you so. Our work starts where a template stops fitting: when speed, search visibility and a precise first impression pay for themselves.

What's included

Everything a business site needs.

Pages, languages and features, and a CMS for editing yourself, are set in your proposal. These come with every build.
  • Custom design in Figma, made for your content
  • Hand-coded Next.js, with no theme or plugins to patch
  • Layouts that hold from 320px phones to wide desktops
  • Usable by people with low vision or without a mouse (WCAG 2.2 AA)
  • Technical SEO: metadata, schema, XML sitemap, clean URLs
  • Each language has its own pages, with hreflang tags that help Google show the right language version.
  • A contact form that delivers straight to your inbox
  • Search Console and analytics setup
  • Your domain, registered in your name
  • A plan of the structure and page content before design
  • Training and handover at launch

Multilingual websites

Multilingual, without shortcuts.

Selling in more than one country means more than one language, and a translation widget doesn't count. Every language we build gets its own pages that Google can index and show to the right people.

Read more
  • One URL per language, such as /en/work-with-us and /sr/ponude, with no cookies or browser guessing.
  • hreflang tags that link each page to its translations, with x-default for everyone else.
  • Translated titles, meta descriptions and structured data, not only the visible text.
  • A language switch that lands on the same page in the other language, not on the home page.
  • A sitemap that lists every language version.

The number of languages is set in your proposal. You can see the setup on this site: kvant.studio runs in English, Serbian and Croatian, with localized URLs and reciprocal hreflang on every page it translates.

Process

From brief to launch in four steps.

You always know what happens next, who is doing it, and when it ships.
  1. 01

    Brief

    Tell us about your business, customers and deadline in a short form or email. We clarify the details in writing or on a short video call, then send a proposal.

    Proposal

  2. 02

    Design

    We plan the sitemap and page content first, then design the key pages in Figma. The number of revision rounds is in the proposal, and you approve the design when it is right for your business.

    Structure first, then design

  3. 03

    Build

    We code the site in Next.js on a private preview link. You click through real pages, not screenshots, while we connect forms, CMS and analytics.

    Private preview link

  4. 04

    Launch & care

    We launch, redirect any old URLs, submit the sitemap and train your team. Maintenance and further development are then agreed to fit the site and your needs.

Project

Proof you can open.

Morava Modern is the house-plan catalog of CAD ART, our family's architecture practice, and the kind of site this page is about: custom-designed, hand-coded and built around a short path from browsing to an inquiry. We measure its scores on the live site.
  • Next.js 16
  • Static
  • Vercel
  • Product schema
Problem
Buyers compare floor plans, sizes and styles across many pages before they write to anyone. Slow pages lose them.
Build
A static catalog with filters, collections, plan galleries, 3D interior tours and a short path to an order request.

We built for ourselves first

We needed a site that brings in clients.

For CAD ART, our family's architecture practice, we designed, built and ranked projektikuce.rs ourselves.

From a client

“They already run one business as a family, and now they’ve started a second one and made a gorgeous website for my beauty salon. […] everything in one place, clearly laid out, concise, and showing everything you need when choosing a salon.”

The Kvant Partner approach

Your website, connected to your business.

A business site pays off when the tools around it work too. We set them up with you and tell you which ones are worth it for your business. We set up Search Console and analytics on every site. Everything else is listed in your proposal, with its price, before you sign.

How the Kvant Partner approach works

What we connect for a business website

  • Google Business Profile

    Your listing on Google Maps and in local results, linked to the right page, with hours and services that match your site.

  • Search Console and analytics

    Set up on every site we build, so you can see which searches find you and which pages people visit. Real inquiries are counted separately from contact clicks.

  • WhatsApp and Viber

    One tap from any page to a conversation. Many customers would rather send a message than fill in a form.

  • Inquiries in one place

    Form messages go straight to your inbox, and into a CRM or newsletter list once there are too many to track by hand.

  • Link previews

    The right title and image when someone shares your page on LinkedIn, Facebook or in a chat.

  • Articles people search for

    On an SEO plan we write them too, built around the questions your customers ask before they buy.

Where we work

Based in Serbia, working everywhere.

Kvant Studio is a family studio in Serbia, on Central European Time. The work happens online: a video call to start, a shared Figma file, and a preview link you open on your own phone. It runs the same way whether your business is in Kragujevac, Osijek, Berlin or Chicago.

CET overlaps with the UK and the rest of Europe for the whole working day, and with the US East Coast through your morning. We answer your questions personally, and you talk to the people who design and build your site, not to an account manager.

We invoice in EUR. For longer engagements, see nearshore web development.

FAQ

Web design questions.

Do I need a website if I already have Instagram?

Instagram is useful for sharing updates, showing your work and talking with customers. In BrightLocal's 2026 survey of 1,002 US adults, 54% said they check a business's website after reading positive reviews and 24% said they check its social media. A website can put everything customers need in one place: your services, what each one includes, answers to common questions and how to reach you. If customers already find everything they need on your profile, first check what a website would make easier for them.

For the beauty studio DolceVita by Irma we created service pages and a price list, with contact options for booking by phone, Viber, WhatsApp or Instagram. A single offer may need only one page; several different services may need pages of their own. Tell us about your business and what customers ask most, and we'll suggest the right scope.

How much does a custom website cost?

The price follows the scope: which pages you need, who prepares the texts and photos, how many languages, which features and integrations, and when the site has to be ready. After a short exchange, before we start, you get a proposal with a fixed price for the agreed scope, and anything added to the work is agreed before we do it. We charge no VAT on our invoices. Businesses in the EU account for it under the reverse charge. See what shapes the scope and price of your website.

How does payment work?

The proposal states the scope, price and timeline. Payment then follows this order:

  • A first payment starts the work.
  • The rest is due when you approve the site, before launch.
  • You pay by bank transfer against a pro-forma invoice. We invoice in EUR.
  • We charge no VAT on our invoices. Businesses in the EU account for it under the reverse charge.
  • Maintenance is a separate monthly service. It is optional, and you can cancel it.

How long does it take to build a website?

It depends on the scope. A simple site can be ready in two weeks, and a business site with several pages usually takes 3 to 7 weeks. Content is the biggest variable: when texts and photos are ready at the start, we finish sooner. The proposal lists the phases and the timeline, and the launch date goes into the contract.

Do you use WordPress or a website builder?

No. We write the site in Next.js, so there is no plugin stack to update and patch. You can still edit content yourself: when the site needs it, we build in Sanity, a visual CMS. We compare both approaches in Next.js vs WordPress.

Is a custom website better than a template?

Not always. A template can be the quicker start, and if one fits your business we will tell you. A custom site is designed around your content and customers and coded by hand in Next.js, with no theme or plugin stack to patch, which is why we can put speed in the contract.

Do I need to provide the texts and photos?

You provide the facts and raw material, because nobody knows your business better. We polish the copy and structure it for search, and when a page needs writing from scratch, we write it. The proposal says who prepares the texts and photos. If you don't have photos, we can create AI visuals to set the tone of the site. We don't present them as examples of your work or results.

Can the site be in more than one language?

Yes. Every language gets its own URLs, metadata and schema, not a translation widget: see how multilingual sites work. The number of languages, and who prepares each version, is set in your proposal.

What happens after launch?

For 30 days after launch we fix bugs for free. You can host the site on your own account or with us. Maintenance and development are agreed separately: technical care, content changes and new features, scoped to the site. SEO and content work is a separate plan.

Anatomy

What goes into every page.

Alongside the design, we build the structure and technical details that help customers use your site and search engines understand it.
  1. 1

    Title & meta

    Written per page, within the length Google displays, with the keyword up front.

  2. 2

    One H1

    One clear headline that says what you do and for whom, with the main keyword in it.

  3. 3

    Hero image

    AVIF or WebP, preloaded, with fixed dimensions, so nothing jumps while the page loads.

  4. 4

    Structured data

    Schema.org for your organization, services, FAQs and breadcrumbs.

  5. 5

    Languages

    Localized URLs and reciprocal hreflang, so each market gets its own page.

  6. 6

    Next step

    One primary call to action and a short form. Spam is filtered quietly, with no CAPTCHA puzzles.

  7. 7

    Accessibility

    Visible focus, enough contrast and full keyboard use, to WCAG 2.2 AA.

Services

One studio for the whole site.

Web design is where most projects start. When you need more, it comes from the same people, and every job gets a proposal.
  1. Ecommerce development

    Stores with Stripe checkout, product schema and multi-currency, from the catalog to the order.

    Shopify or Next.js

  2. SEO & AI search

    A plan for your searches

  3. Website redesign

    A clearer site, with a planned content move and 301 redirects for every URL that brings visits.

    Free audit
