Buyer’s Checklist

What to look for in a e-commerce mobile app developer in Katowice

These are the questions and checks that separate e-commerce specialists from general app agencies who will list your sector on their homepage after you sign.

Published live stores with page speed scores above 80 on GTmetrix: ask for the report before signing

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 Katowice

SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt

Post-launch support with a defined SLA. E-commerce sites fail during peak traffic, usually when you least want to be calling a developer

Platforms & Tech Stack

Which platform for e-commerce in Katowice?

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 becomes the correct choice at high annual GMV, from around £500,000 in the UK and the local equivalent elsewhere.

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 Katowice agencies have this.

Questions & Answers

E-commerce mobile app development in Katowice - common questions

Pre-brief questions that e-commerce businesses in Katowice ask before commissioning an app project.

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 Katowice or will any web developer do?+

E-commerce development requires specific expertise that general mobile app developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and App Store ratings 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 Katowice business look for in a contract before hiring a web developer?+

A properly scoped mobile app development contract for a Katowice 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 Katowice mobile app development market.

How long does a Katowice web project typically take from brief to launch?+

A standard business app for a Katowice 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 Katowice web projects is late content delivery from the client, agree a content deadline before the project starts and the timeline holds reliably.

Should a Katowice business hire a local web developer or work with a remote agency?+

For most Katowice businesses, a remote mobile app 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 mobile app development quality since 2018. Tecklogist serves clients across Poland and 40+ countries entirely remotely.

How can a Katowice business verify a web developer's experience before signing?+

The three most reliable verification methods for Katowice businesses evaluating mobile app 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. Tecklogist provides live portfolio URLs, verified client references, and a free technical scoping call for every Katowice project enquiry.
