Online Store
What is a modern online store and why can it benefit you?






















An online store isn't just a platform for sales - it's a strategic tool capable of significantly increasing your business revenue and brand visibility.
Depending on your company's needs, you can implement a simple form with a payment gateway for a single product/service, choose a dedicated solution using modern technologies or WooCommerce based on WordPress, or Shopify/PrestaShop - each of these approaches gives you the freedom to integrate with your ERP, CRM or other services.
Who is it ideal for? For businesses selling both physical and digital products (courses, e-books), as well as service providers wanting to automate the booking or online payment process.
Why distinguish between "custom" and "ready‑made" stores?
- CUSTOM(built from scratch, e.g., using Next.js (React) + Node.js) provide full control and flexibility. Ideal for complex integrations with ERP or unique modules, such as product configurators.
- READY-MADE(e.g., WooCommerce or PrestaShop / Shopify) allow faster market entry and lower initial costs, but require code editing/development or plugin selection and may be more difficult to expand if your business grows in an unexpected direction.


# Why choose it? / Business Benefits
-
Expanded Market Reach
With a combination of optimization for SEO and AI Overview (React, Next.js, Google Tag Manager, Google Analytics) and attractive design, as well as internalization and localization systems, the store is accessible to clients 24/7 from around the world, increasing reach and potential revenue. -
Better Customer Service
Integrations with CRM or shipping systems allow orders to be processed quickly, and an interactive customer panel allows you to view package status, purchase history and intuitively handle complaints or order modifications. -
Higher Conversion Rates
A simple shopping cart, clear layout and ergonomics of the interface (Usability) reduce shopping cart drop-off, which directly results in increased sales. -
Sales Process Automation
Automatic invoicing, discounting system and loyalty modules allow you to attract clients and build permanent relationships, saving you time - everything can be done automatically. -
Scalability and Customization
The customized variant allows the introduction of typical functions (e.g., customizable product, dynamic pricing), while WooCommerce or Shopify/PrestaShop offer thousands of plugins that can extend functionality even at a later stage of development, which, however, results in optimization, so often simple solutions are coded at the request of the orderer. -
Transaction Security
Responsiveness, Modern UI appearance, SSL encryption, and certified payment operators (Stripe, Przelewy24, PayU) ensure that your clients feel secure when making purchases in your e-store.

# Types and Development/Expansion Possibilities
# Custom Online Store with REST API / GraphQL
A "tailor-made" solution – ideal for companies that require non-standard functionalities (e.g., product configurator, advanced discount rules).

# Collaboration Process / Methodology
-
Contact & Needs Analysis A conversation or workshop helps determine if a simple form with payment or WooCommerce is enough, or if a “Custom” implementation (React + Node.js / PHP) is advisable. Together we define key features (e.g. B2B panel, product configurator, ERP integrations).

UI/UX Design For the dedicated option: I prepare mockups and prototypes in Figma, which are then tested for usability (UI/UX). We work with you to determine what the homepage, categories, product and other key elements should look like. Mobile-first design with responsiveness and accessibility in mind.
- Prototype - visualization of the user interface (UI) and user experience (UX).
- Design system - a set of principles and components for creating consistent interfaces.
- Interactive prototypes - enable testing of functionality before implementation.
- Utility tests - studies that help understand how users use the application and what can be improved.
- Feedback collection - analyze user feedback and make improvements.
For the finished option: I choose a suitable template from the repositories (e.g. Own repo, Envato, ThemeForest) and customize it according to your needs.
-
Architecture and Configuration I prepare the architecture of the system, databases and integration. For the dedicated option, I build the back-end (Node.js or PHP) and the front-end (React + Next.js). In the case of WooCommerce, I configure WordPress and WooCommerce, as well as the necessary plugins.
-
Implementation & Testing I implement the system on the production server, perform functionality, performance and security testing. I use CI/CD tools to automate the deployment process. For the dedicated option, I use Docker and containerization to ensure easy deployment and scaling.
-
Publication and post-launch support Once testing is complete, I publish the store online. I provide training on how to use the admin panel and provide technical support in the first months after launch. I provide warranty depending on the contract: minimum 6, 12, 24 months.
-
Maintenance and Development I provide system updates, transaction security, and support for advertising campaigns (Google Ads, Facebook Ads). Further integrations (e.g. marketing automation, loyalty program) are optional.
Timeline From several days (simple store with standard functionality) to several months (extensive, custom projects with advanced integrations). All based on a set schedule, taking into account your priorities. I recommend an agile approach, regular meetings and preliminary workshops.
