E-Commerce Development

What our e-commerce development services include

Slovak e-commerce grew 6% to €1.84 billion in 2024, the second-highest year in its history, according to Heureka Group (2025). The number of active e-shops fell to roughly 13,900 in the same year (Heureka data via Ecommerce Bridge, 2025). More revenue, fewer stores. Buyers are consolidating around shops that work, and build quality decides which side of that line you land on.

• Platform selection and store architecture: Shopify, WooCommerce, headless, or fully custom, chosen against your catalog, margins, and markets rather than our preferences.
• Conversion-first store design: category logic, product pages, and checkout flows shaped with our UI/UX design practice, because most revenue leaks out between product page and payment.
• Storefront development: fast, accessible, mobile-first code your team can maintain after we leave.
• Payments, shipping, and back-office integrations: gateways, carriers, invoicing, ERP and CRM connections, and product feeds, wired so orders flow without manual work.
• Migrations and replatforming: moving an existing store to a new platform with its search rankings intact.
• Multi-language, multi-currency setup: cross-border EU selling prepared from day one, not retrofitted later.

One honest boundary first: a DIY builder can put a small store online in a weekend, and for testing demand that is a fair choice. You hire an e-commerce development agency when the store carries real revenue: when half a percent of conversion, a failed carrier integration, or a botched migration costs actual money.

What does our e-commerce development process look like?

1. Scope and platform decision. We map catalog size, integrations, markets, and margins, then fix deliverables and price in writing before work starts. If a cheaper platform serves you better, that is the recommendation you will get.
2. Store design. Category structure, product page templates, and checkout are designed around buying behavior and agreed as clickable screens before development begins.
3. Build and integrate. Storefront, payment gateway, carriers, invoicing, and product feeds come together on a staging store you can click through weeks before launch.
4. Test real flows. We run orders end to end on desktop and on mobile: payment, shipping rules, tax, confirmation emails, returns.
5. Launch with redirects and measurement. DNS, 301 maps for migrations, analytics, and consent are handled from a checklist, so launch day is boring by design.
6. Improve after launch. Conversion data starts arriving on day one; a first optimization pass is part of the engagement, and our digital marketing team can take over traffic from there.

Shopify, WooCommerce, or custom: what should your store run on?

Platform religion is expensive. Each option wins a specific situation, and the choice belongs at the start of the project, in writing, with reasoning. Replatforming later costs a multiple of choosing well now.

• Shopify: fastest to launch and lightest to operate, with a strong native checkout. Our Shopify development services cover theme development, app integration, and checkout customization. Trade-off: monthly fees and platform limits.
• WooCommerce: full ownership on WordPress and lower running costs, strong when content drives your selling. Trade-off: you carry more maintenance responsibility.
• Custom and headless storefronts: for stores the platforms constrain: marketplace mechanics, product configurators, unusual checkout logic, or deep ERP integration. We build these with our web app development team.

E-commerce website design that converts on mobile

The audience exists: 73% of Europeans aged 16–74 bought online in 2024, according to the European E-commerce Report 2025 from Ecommerce Europe and EuroCommerce. Conversion is the constraint. The average online store converted about 2.5% of visits in Q3 2025, with desktop at roughly 3.9% and mobile at 1.8%, according to Contentsquare data reported by Smart Insights (2025). That two-times gap is where stores quietly lose money, usually because their design decisions were made on a desktop monitor.

So we design and build mobile-first as a default, not an option: thumb-reachable navigation, product pages that stay fast on weak connections, forms cut to the minimum, wallet payments so checkout takes seconds. Every removed step is measurable money.

Store migrations and redesigns that keep your rankings

The usual reason merchants postpone a needed replatforming is fear of losing Google positions. The fear is rational: careless migrations do exactly that. Ours start with a full crawl of the existing store: every URL inventoried and mapped to a 301 redirect, product content and metadata carried over, structured data rebuilt on the new platform, and search performance monitored daily after launch. Expect a few weeks of small fluctuation, not a collapse. If you are moving from a rented builder platform to a store you own, this is the part of any quote to read most carefully.

How much does ecommerce website development cost?

Anyone quoting a price before scoping your store is guessing. Five inputs set the real number: platform, catalog complexity (ten products behave differently from ten thousand), the integration count across payments, carriers, invoicing, and ERP, design depth, and how many languages and markets the store serves. A template-based Shopify or WooCommerce build sits at the low end of the range; custom e-commerce development for multiple markets sits at the top.

Two things stay fixed either way: scope and price. Every engagement is quoted as defined deliverables at a fixed price before work begins, so the number cannot drift mid-project. The right way to start depends on where you stand: for an existing shop, a store audit that shows whether you need a rebuild or two weeks of targeted fixes; for a new one, a template-based build designed to be extended rather than replaced. The runway rewards building properly: Slovakia’s e-commerce market alone is forecast to grow from US$2.84 billion in 2026 to US$4.74 billion by 2031, according to Mordor Intelligence (2026).
