What is online store design?

Definition and scope of e-commerce services

Online store design is the process of building online sales platforms. It covers analysing business needs, designing the purchase path, preparing the UX/UI, implementing the e-commerce engine, integrating payments and logistics, and optimising for SEO and CRO.

Why are online stores crucial in 2026?

According to Statista 2024, the global e-commerce market will exceed USD 7.4 trillion in 2025. In Poland over 80% of internet users already shop online regularly, and the fastest-growing sectors are fashion, electronics, cosmetics and FMCG. As a result a professionally designed online store is becoming a basic tool for sales and building competitive advantage.

How much does online store design cost in 2026?

Factors affecting the price (CMS, UX/UI, integrations, SEO)

The cost of an online store depends on:

• the platform (CMS) chosen – WooCommerce, PrestaShop, Shopify, Shoper, custom solutions,
• the UX/UI design – a bespoke design optimised for conversion vs off-the-shelf templates,
• the number of products and categories – from a few dozen to tens of thousands,
• integrations – online payments, ERP systems, Baselinker, CRM, couriers, marketplaces (Allegro, Amazon),
• SEO and technical optimisation – category structure, page speed, Core Web Vitals,
• security and GDPR – SSL certificates, privacy policy, customer data protection.

Price ranges – small stores, mid-sized platforms, custom solutions

• Maintenance and updates: PLN 500–2,000 a month depending on scale.

The stages of designing an online store

Business analysis and e-commerce workshops

The first step is analysing business goals and running workshops that define the target group, the product range, the sales channels and the required integrations.

UX/UI design and the purchase path

At this stage the store's wireframes and graphic design are created. Particular emphasis is placed on user experience – a simple purchase path from the product page to payment.

CMS implementation and integrations (ERP, payments, Baselinker)

The agency implements the chosen CMS and integrates the store with payment systems (PayU, Przelewy24), ERP, CRM, Baselinker and courier services.

Testing, optimisation and launch

Before publication the store goes through testing: cart, payments, load speed, security. Analytics are added too (GA4, Tag Manager, heatmaps).

Online store design and the choice of platform

WooCommerce – for smaller stores

Ideal for small and medium companies. Advantages: low implementation costs, flexibility, ease of use.

PrestaShop – for mid-sized and growing businesses

A more extensive platform, better for stores with a larger number of products. Popular in Poland thanks to its openness and scalability.

Shopify and Shoper – fast SaaS deployment

A good choice for companies that want to launch quickly. Limitations: less flexibility, subscription costs.

Custom solutions – for large e-commerce and marketplaces

For brands with large budgets requiring custom features (e.g. a marketplace, warehouse integrations, personalised offers).

What to look out for when choosing an e-commerce agency?

Experience and an e-commerce portfolio

The agency should have experience with similar projects – e.g. stores of a comparable scale or industry.

Transparent pricing and project stages

A reliable agency provides a detailed cost estimate and schedule, with no hidden costs.

Technologies, integrations and post-launch support

The agency should advise on the CMS choice and provide support after launch: updates, backups, further development of the store.

How does online store design connect with digital marketing?

SEO and content marketing for e-commerce

A store has to be optimised for search engines – unique product descriptions, category structure, an industry blog.

Performance marketing and remarketing

Google Ads, Meta Ads and remarketing are key tools for increasing sales.

Marketing automation and abandoned carts

Automated email campaigns, push notifications and abandoned cart recovery increase conversion by as much as 20–30%.

Omnichannel – integrating offline and online

Connecting in-store and online sales (e.g. click and collect, ERP integration) is becoming a standard in 2026.
