Web development: websites, stores, integrations, upgrades, web apps

People come to us for website development with one of three requests: they need a first website, they need to replace the one they have, or they need someone else's work finished. The sections below are split along exactly these lines, because the answer shapes everything else: the scope, the timeline and whether starting from scratch makes sense at all. The most expensive mistake here isn't technical. It's ordering something big where a simpler build would do, or rewriting a site that only needed improvements. So each page below describes what is included and also where the limits are: when an option fits and when another one is the better choice. We calculate the cost after a free review, because before that any figure would be made up.

How it works

What web development consists of, and how we get to launch step by step

  1. First we define the task and structure

    We define what the site must do, which pages and data it needs, and what it has to connect with.

  2. We build the base and integrations

    Catalog, cart, payment, delivery and your accounting service are put together into one working system.

  3. We test and hand it over

    Before launch we test buyer scenarios; after the act, the domain, hosting and code belong to you.

Scope and timing depend on the task and the number of integrations. We give an estimate by stages after a brief or an audit, not upfront.

Situations where this service delivers results

Scenario 1 of 4

You don't have a website yet

The main decision here is the type of site, not the design: a business card site, a landing page, a catalog or a store. They differ less in budget than in where people come from and what they need to do. The Websites section is organized around exactly that; stores have a section of their own, because there the question starts with the catalog.

What's included

Complete list of work and what you get as a result

  • A free review of the task before any commitments, with an answer about what you actually need, even if it costs less than what you came for
  • An estimate broken down by stages with a timeline in working days instead of a turnkey site in a week: the clock starts once access and materials are in place
  • A written contract for every project: scope, timeline, price and acceptance procedure are fixed before work begins
  • Interim reviews on a live environment rather than in descriptions, so the direction can change while that is still cheap
  • Domain, hosting, repository and analytics registered to you from day one
  • A client portal for the duration of the work, with your contracts, invoices, acceptance acts and project status
  • Handover under an acceptance act and a 30-calendar-day warranty on the completed work
Process steps

Transparent stages with approval at every step

  1. Free review

    1–3 days

    We clarify the task and tell you what it needs: a new site, improvements to the existing one or a different solution altogether. This is also where it becomes clear which of the four sections to start with.

  2. Estimate and contract

    1–3 days

    We state the scope, the timeline in working days and the price broken down by stages, then put it in writing. The acceptance procedure and warranty go into the contract too, instead of living in chat messages.

  3. Work with interim reviews

    depends on scope

    We build the project in parts and show the result on a live environment. You see how it really looks and can still change direction while a correction costs only a conversation.

  4. Launch, handover, warranty

    2–5 days

    We move the site to your hosting, hand over access and documentation, and sign the acceptance act. From that day, the 30-calendar-day warranty on the completed work applies.

When this service isn't right

What's not included — so there are no surprises at delivery

  • Timelines quoted before the scope is reviewed: tasks with the same name can differ several times over, and an honest figure only appears after a proper look
  • Promises about sales or search rankings: a website affects whether a visitor takes action, not demand or competition
  • Mobile apps for the App Store and Google Play, which have a separate release cycle we don't work with
  • Work without a responsible person on your side: the client decides on structure and copy, and without that the project stalls
  • Projects where expectations clearly don't match the budget from the start: in such cases we decline in our first email

FAQ

Questions asked before starting

Where do I start if I don't know exactly what I need yet?

With a review of the task: it's free and takes one to three working days. You describe what needs to happen in your business, and we tell you which solution covers it. Quite often the answer is cheaper than expected: improving the current site instead of building a new one, a catalog without a cart instead of a store.

Why are there no prices on the website?

Because the scope of work with the same name differs several times over between two clients, and a "starting from" figure would be misleading. The process goes like this: first a free review, then an estimate broken down by stages, then a contract with a fixed price. That way you know the final figure before work starts, not after.

Do you work under a contract?

Yes, for every project. The contractor is a registered Ukrainian sole proprietor (FOP), and payment goes to a bank account with full closing documents. The contract fixes the scope, timeline, price and acceptance procedure; the result is handed over under an acceptance act, and a 30-calendar-day warranty applies from the day it is signed.

Who will own the website?

You will. Property rights to the code, design and materials pass to the client after full payment. We register the domain, hosting, repository, analytics and ad accounts to you right away, not at the end, so that changing contractors never means losing the project.

What does the timeline depend on, and why isn't it given right away?

The timeline is driven by scope more than by complexity: the number of pages, the number of integrations and whether the content is ready. So we give a figure after the review and count it from the moment access and materials are available, not from the contract date. This matters in practice: the most common reason for delays is waiting for copy and photos from the client rather than development itself, and no number of people on the project changes that.

Do you take over projects started by other developers?

Yes, taking over a project is a separate type of work in the improvements section. It starts with an inventory instead of code: what access exists, what state the code is in and which of the promised features were actually built. After that we tell you directly whether to improve or rebuild, even when staying quiet would pay us better.

Who exactly will work on my project?

Your task goes straight into work, with no account managers and nothing relayed through third parties, and the project isn't handed to someone else midway. Response time is two hours during business hours. That's what you will see in practice; other details of how the work is organized make no difference to the result.

What should I prepare to order website development?

A few sentences are enough: what you sell, who your buyer is and what a visitor should do on the site, whether that's calling, leaving a request or buying. If you have examples of sites you like or find annoying, include them: that saves a day of clarifications. You don't need to write a technical specification. During the free review we ask the questions ourselves and come back with a structure and a list of pages. Copy, photos and company details will be needed later, and how ready they are most often determines the timeline.

Are you a web studio or a web development agency?

LIONEX AI First Agency is an agency by name and, legally, a registered sole proprietor (FOP): a contract for every project, payment to a bank account, closing documents. What matters more to you is how this looks in practice. Your task goes straight into work, with no account managers and nothing relayed through third parties, and the project isn't handed to someone else midway. We respond within two hours during business hours. Commercial development since 2015, 53 projects in the portfolio, 33 of them online stores.
