Custom web application development

Custom web development: marketing sites, client portals, SaaS, and admin panels on a modern stack.

How project pricing works

Need a corporate website, client portal, or web application that will grow with you? We do custom web development on React and Next.js — with clear scope, SEO basics, and code you fully own.

Websites and web applications for business — from a landing page to a full online product.

Web development covers everything users open in a browser: marketing sites, SaaS products, admin panels, and personal accounts. We agree upfront what goes into the first version and what waits. The stack is modern and open — no lock-in to a closed platform.

Why businesses order custom web development

01

A site or app tailored to your process — not a template with limits.

02

You control the product. Source code and domain stay with you.

03

Easy to scale: add sections, roles, and integrations step by step.

04

Transparent delivery: weekly updates and milestone payments.

What a web application costs and how long it takes

We start from the product type, user roles, integrations and the first version. The estimate and the calendar follow that, not an average price per page.

What changes the price

A marketing site, a client portal and a SaaS product are different amounts of design and engineering. The estimate follows the scenarios you actually need.

  • Roles, sections and business scenarios
  • Backend, database and an admin area
  • CRM, payments, analytics and external APIs
  • Security, load and SEO requirements

How the plan is built

The timeline depends on how ready the requirements are and how many flows depend on each other. We ship a first working version in stages instead of hiding the launch at the end of a long project.

  • Pages, roles and the main user actions are agreed first
  • Work proceeds in short stages with regular demos
  • Data migration, integrations and launch are planned up front

Questions about web development

Scope, integrations and how the finished product is handed over.

How is a web application different from a website?

A website mainly presents information and collects enquiries. A web application lets someone do the work: use an account, place an order, manage data, pay, or work with other people in the system.

How much does a web application cost?

It depends on roles, backend logic, integrations, interface size and load. After a short brief we separate the first version and send a staged estimate, usually within two business days.

Do you build the backend and admin area?

Yes. Frontend, backend, database and admin can be one product, or we can connect to a server you already have.

Can you integrate a CRM, payments or an external API?

Yes. Before development we check the documentation and the limits, describe the data exchange and include the integration in the estimate and the test plan.

Can you continue an existing codebase?

Yes. We start with a technical review of the code, infrastructure and risks, then propose a plan. We do not promise a rewrite before we have seen the system.

How is the code handed over?

The repository, documentation and access are transferred to you. The product is not locked to a closed Inu-apps platform.
