We build software

A short path from idea to production.

Web apps, integrations, online stores and websites. We work with companies for which software is a real tool — not just an online presence.

Services

Web applications, websites and online stores.

From a single page, through a shop, to a full web platform. Scale picked to fit the need — not the other way around.

  • Web applications

    Custom platforms, dashboards, integrations with systems and APIs. Stack picked per project — from MVP to a production system handling real traffic.

  • Websites & e-commerce

    Landing pages, storefronts and small business sites. Fast, accessible, easy to maintain — without the WordPress overhead.

    More about websites
  • Care & visibility

    Maintenance for websites and stores — including ones we didn't build. Updates, content changes, Google Business Profile and analytics, from €35 per month.

Process

Four steps. No corporate theatre.

  1. 01

    Conversation

    30–60 minutes to understand goal, constraints and context. We say so plainly if it's not a fit.

  2. 02

    Proposal

    A concrete proposal: scope, timeline, cost. No hidden line items, no 'starting from'.

  3. 03

    Build

    Short iterations, regular previews, one point of contact on our side. No three-week disappearances.

  4. 04

    Launch & support

    Go-live, team handover and post-launch support. We stick around — the product keeps going.

About

Two friends. One studio.

We're Marcin and Tymek — we've known each other for more than 20 years and have been working together for several. Both of us have spent years in commercial international IT projects. MZSoft is how we do this on our own terms: no agency layer, no middlemen, clear ownership.

FAQ

Frequently asked questions.

Short answers to what we get asked most.

Ask us a question
How much does a website or web application cost?

It depends on scope, but we like specifics. A simple brochure site is a fixed-price Starter Pack at €350, a company website usually runs €1,000–2,000, a small store from roughly €700, and a web app prototype from around €1,200. Every website includes the first year of domain, hosting and technical care. After the first call you get a quote with a concrete figure — no vague 'from…' and no hidden line items.

Can I pay monthly instead of up front?

Yes. You can have a simple site (Starter Pack scope) on a subscription: no setup fee and €45 net per month for 12 months — design, hosting, domain, updates and small content changes included. After 12 paid months the site becomes your property. A bigger site means a higher monthly rate, quoted concretely. We can also take care of an existing site from €35 per month.

Do you also build simple sites, e.g. on WordPress?

Yes. We work on large platforms, but we're just as happy to build a simple, low-maintenance company website — including on WordPress or a ready-made template, if that's the best fit for your budget. We pick the tool to fit the need, not the other way around, and we won't push a pricier option when there's no reason to.

How long does a project take?

We usually deliver a company website in 2–4 weeks, a shop or larger site in 4–8 weeks, and we build web apps in short iterations with regular previews — a working prototype typically lands in 2–4 weeks, a full MVP in 4–8.

How is a software house different from an agency or a freelancer?

You work directly with the people who write the code and design the product — no middle layers, no handing the project between people. Unlike a single freelancer, we cover the full set of skills (engineering + product) and we don't disappear as the project grows.

Do you handle maintenance after launch?

Yes. After launch we stay in touch — we maintain, develop and support products long-term. Care plans start at €35 net per month and cover sites we didn't build, too. We also help with Google Business Profile and analytics.

What technologies do you use?

We pick the stack to fit the project, not the other way around. For larger applications that's usually modern web technologies (Angular, TypeScript, Node and friends). For simpler sites we reach for lighter solutions or WordPress — so they stay fast and cheap to maintain. If an approach doesn't make sense in your case, we'll say so up front.

Do you work remotely and with clients across Poland?

Yes. We work fully remotely and partner with companies across Poland. The whole process — from the first call through previews to launch — runs online.
