White-label web development for agencies.

Hand us one landing page for a real client: our Launch package at the published €1,490, live in 7–10 working days, built in your repo under your brand. It runs on our standard terms: Lighthouse mobile 95+ at handover or we fix it for free, and the launch date in the contract with a 5% credit per late week, capped at 20%. You see how we communicate, how clean the code is and whether we hit the date before you trust us with a bigger client.

White-label

You front everything. Your team talks to the client, collects feedback and forwards it to us. We never appear in email threads, calls or commit messages the client can see. This suits agencies that already run their own project management and want a build team behind it.

Co-delivery

We join your calls under your brand, as part of your team. You decide how we are introduced. This suits projects where the client wants to hear technical answers first-hand, like a migration or a multilingual rollout, and you would rather not relay every question.

Either way, one of the two founders, Jovan or Branko, is your contact from brief to handover. There is no account manager in between.

Shops: we build on Shopify or on Next.js with Medusa. Before you commit, we walk you through how we would build your client's store: theme or headless, apps, product migration and the launch plan. See what goes into a store build.

Our public work is three live sites we designed and built end to end, and every one is open for inspection. Moravamodern sells house plans in English to buyers abroad, projektikuce.rs is a Serbian catalog that grew on search alone, and DolceVita by Irma took a beauty studio from Instagram to a site of its own. Open any of them on your phone and run Lighthouse yourself.

Your projects get the same build and stay under your brand: NDA before the brief, your repositories, no contact with your client. Then test us the way you would test any partner: with one pilot project.

Every package above is a fixed price. Work outside the agreed scope is €55/h, approved in advance. For comparison, the median hourly rate for software and web development freelancers in Germany, Austria and Switzerland is €90 (freelancermap, 2 Jul 2026).

Payment follows the same schedule as for any other client:

• Under €2,000: 50% on signing, 50% before launch.
• €2,000–9,999: 40% on signing, 30% on design approval, 30% before launch.
• Shops, apps and anything €10,000+: 30 / 30 / 30 / 10. The final 10% is due 14 days after launch.
• Quotes are valid for 30 days.
• Invoices are issued in EUR.
• Out-of-scope work: €55/h.
• Rush delivery: +25%.

You set your resale price. We never talk to your client about money, and our invoice goes to you, not to them.

Partner terms. Your first project, often the pilot, runs at the published price. From your second signed project, every package is 10% off. With steady work, we add a framework agreement for volume, reserved capacity and response times, on terms we agree together.

Your contracting party is Jovan Milivojević PR Arhitektonski biro CadArt Paraćin, a registered Serbian business (registration number 64929097, tax ID 110627690). Kvant Studio is its trade name. It is run by Jovan Milivojević, an architect who has run his own business for 15 years.

• Invoices are issued in EUR and paid by bank transfer.
• Serbia is outside the EU, so EU and UK businesses usually account for VAT themselves under reverse charge. Your accountant confirms the details for your country.
• Intellectual property in the work transfers to your agency after the final payment.
• The NDA is yours: we sign it before the brief.
