Winning e-commerce traffic in Kaunas is only half the battle — converting it is where most online stores fail. The average e-commerce site in Kaunas converts 1.5–2.5% of visitors into buyers. The top performers convert at 4–6%. The difference is rarely the product or the price: it is page speed, checkout friction, trust signals, and mobile experience. The web developers on this list have built e-commerce websites in Kaunas that sit in the top tier of conversion performance — because they have studied what the highest-converting stores in the Lithuania market do differently and built those patterns into every site they deliver.

E-commerce sites handling card payments must be PCI DSS compliant-Shopify Payments and Stripe handle this by default; self-hosted payment processing requires a formal PCI Level 1 or Level 4 audit.
Signs of a genuine e-commerce web developer in Kaunas
These are the markers that separate real e-commerce specialists from generalist agencies that just bolt your sector onto their pitch after you sign.

Checkout A/B testing experience: agencies that have run live split tests understand what moves conversion rates beyond gut instinct
Local payment method integrations: Stripe, PayPal, and any market-specific gateways active in Kaunas
SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt
Post-launch support with defined SLA-e-commerce sites fail during peak traffic, usually when you least want to be calling a developer
Platform Choices
Picking the right platform for e-commerce sites in Kaunas
Shopify / Shopify Plus
Best for speed to market. Custom theme development on Shopify 2.0 gives full design control without leaving the hosted platform. Shopify Plus is the correct choice above £500,000 annual GMV.
WooCommerce
Best when the client already runs WordPress or needs customisation beyond Shopify's API surface: subscription logic, complex tax rules, multi-currency with local rounding.
Headless (Next.js + Shopify Storefront API)
Recommended for stores exceeding 10,000 monthly transactions or brands that require sub-1-second product pages. Higher build cost; dramatically better Core Web Vitals scores.
Magento 2 / Adobe Commerce
Enterprise choice for multi-store, multi-language, multi-currency setups. Requires a dedicated Magento-certified developer-not all Kaunas agencies have this.

Common Questions
E-commerce website questions from Kaunas businesses
What e-commerce companies in Kaunas most often ask before kicking off a new website project.
Which e-commerce platform do web developers in Kaunas recommend?+
Shopify is the default recommendation for most Kaunas businesses launching a new store-faster to build, easier to operate, and lower ongoing maintenance. WooCommerce is the right choice when the client already runs WordPress or needs more complex customisation. Headless commerce (Next.js + Shopify API) suits stores exceeding £1M GMV where load speed and UX directly impact revenue.
How much does an e-commerce website cost in Kaunas?+
A Shopify store with brand-customised theme costs £1,500–£5,000 in Kaunas. A custom WooCommerce build with product filtering and payment gateway integration runs £5,000–£18,000. Enterprise headless commerce starts at £25,000. Ongoing costs include hosting (£20–£200/month), platform fees (Shopify £29–£299/month), and maintenance retainers.
How long does e-commerce development take?+
A Shopify store with a customised premium theme takes 1–3 weeks. A custom WooCommerce build is 4–8 weeks from brief to launch. A headless commerce platform with custom checkout flows and ERP integrations is 12–24 weeks. Timelines extend when product data, photography, or payment gateway approvals are delayed.
Do I need a specialist e-commerce agency in Kaunas or will any web developer do?+
E-commerce development requires specific expertise that general web developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and PageSpeed compliance affecting Google Shopping rankings. Ask any candidate agency to show you 3 live stores and their current Core Web Vitals scores in Google Search Console.
What should a Kaunas business look for in a contract before hiring a web developer?+
A properly scoped web development contract for a Kaunas business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the Kaunas web development market.
How long does a Kaunas web project typically take from brief to launch?+
A standard business website for a Kaunas company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Kaunas web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.
Should a Kaunas business hire a local web developer or work with a remote agency?+
For most Kaunas businesses, a remote web development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for web development quality since 2018. Tkist Digital serves clients across Lithuania and 40+ countries entirely remotely.
How can a Kaunas business verify a web developer's experience before signing?+
The three most reliable verification methods for Kaunas businesses evaluating web developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist Digital provides live portfolio URLs, verified client references, and a free technical scoping call for every Kaunas project enquiry.
