Own Modern Online Store

Stop paying commissions - own online store without transaction costs

Allegro commissions range from 2.5% to 17% in 2025 (source: allegro.com). Shopify starts at 19€-27€ monthly + 1.95% per transaction (source: shopify.com). I create commission-free stores tailored to your business. Order a free 30-minute consultation.

I am a programmer and business owner - I've created many online stores, working directly with clients or as a contractor for several agencies. This allows me to specialize in e-commerce from both technical and business perspectives.

I offer three options:

OPTION 1: Custom Store - Pay once. Order includes designing and coding custom UI/UX (interface - template) and custom functionalities, such as configurators, calculators, or integrations with external systems or payment gateways. Example: aserto.pl.
OPTION 2: Ready-made Store - Pay once. Ready-made interface (UI/UX) adapted with your brand colors and identity. PayNow or Stripe payment gateway. Example: zsoli.pl.
OPTION 3: SaaS Model - Recurring payment. Competitive monthly fee tailored to your business, 0% sales commission*. Ready solution with full technical, administrative, and maintenance support.

Perfect solution for small and medium business owners already selling on Allegro, Sky-shop, Shoper, or Shopify who want to become independent from platforms and build their own store.

vs Sky-shop: approx. 773 € annually (77 × 12) - with higher packages the differences are larger
vs Shoper: approx. 682 € annually, promotional package for the first year

Why switch to your own store:

ZERO COMMISSIONS
- every euro of revenue goes to you (vs Allegro 2.5%-17% commission)
OWN CUSTOMER BASE
- don't lose contact after transaction like on marketplace
FULL BRAND CONTROL
- customer buys "from you", not "through platform"
PRICING FREEDOM
- no restrictions on promotions and pricing policy
TAILORED INTEGRATIONS
- connect with your own CRM, warehouse, invoicing
ONE-TIME PAYMENT OR SAAS MODEL
- no development limitations.

Why distinguish between "custom" and "ready‑made" stores?

CUSTOM
(built from scratch, e.g., using Next.js (React) + Node.js / PHP (Laravel, Symfony)) provide full control and flexibility. Ideal for complex integrations with ERP or unique modules, such as product configurators. They ensure full control and flexibility with non-standard functions.
READY-MADE
(e.g., WooCommerce or Shopify/PrestaShop) 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 switch to your own store? My practical experience

I've helped dozens of companies transition from external platforms to their own stores. Average savings are 5,682-11,364 euros annually. Here are the concrete benefits I observe with my clients:

End of growing commissions
Allegro charges commissions from 2.5% to 17% depending on category (source: allegro.com). Shopify is 27€/month + 1.95% per transaction (source: shopify.com). I create stores with 0% commission - all revenue goes to you.
Building a real customer base
On Allegro you lose contact with customers after transaction. In my stores you get full access to data, can build loyalty programs and direct marketing. This is a huge difference in ROI.
Full control over your brand
Customer buys "from you", not "through platform". You can shape the shopping experience, your own pricing policy and communication. This builds trust and recognition.
Better margins by eliminating commissions
Without commissions you can offer competitive prices to customers or increase margins. Plus cross-selling and up-selling opportunities without sharing revenue.
Scalability without cost limitations
The more you sell, the more you save on commissions. Sales growth = savings growth, not cost growth like on platforms.
Modern technology ready for the future
I build stores in Next.js that can be easily integrated with AI and extended with chatbots, personalization, ERP/CRM system integrations. It's an investment in the future.
Dedicated e-commerce specialist for store management
I offer the possibility of hiring a dedicated specialist who will manage your store, update products, handle orders and customers. This is an ideal solution for companies that don't have time or resources for daily store management.
