Selling Online — How to Start Earning Money on the Internet in Poland (2026)

Selling Online in Poland — Why Now Is the Best Time

The Polish e-commerce market exceeded 120 billion PLN in 2025 and continues growing at 10–15% annually. This means more Poles are buying online, and the entry barrier for sellers has never been lower. You do not need a warehouse, a physical store, or large capital — a laptop, smartphone, and a good idea are enough.

This guide walks you through the entire process: from choosing a business model to sales platforms to legal and tax considerations.

Online Selling Models — Which One to Choose?

1. Selling Your Own Things (Reselling)

The simplest start. Begin by selling items you no longer need from home — clothing, electronics, books, furniture. This lets you understand platform mechanics without financial risk.

Pros: Zero startup capital, immediate start, no risk. Cons: Limited scale, one-time revenue. Platforms: OLX, Vinted, Allegro Lokalnie.

2. Product Trading (Retail Arbitrage)

You buy products cheaper (wholesalers, clearance sales, imports) and sell them at a higher price on marketplaces. Requires finding good supply sources and niches with margin.

Pros: Proven model, control over the product. Cons: Requires capital for inventory, risk of unsold stock. Potential margin: 20–50% per product.

3. Dropshipping

You sell products without holding inventory. When a customer places an order, your supplier ships the product directly to the buyer.

Pros: Minimal startup capital (1,000–3,000 PLN), no warehouse issues. Cons: Lower margins (10–30%), no control over shipping and quality, competition. Suppliers in Poland: Baselinker, Hurtownie.pl, Apilo.

4. Print-on-Demand

You design graphics for t-shirts, mugs, posters — production and shipping happen automatically after each order.

Pros: Zero financial risk, creative work, passive nature. Cons: Low per-unit margin, requires brand building. Platforms: Printful, Merch by Amazon, RedBubble.

5. Digital Products

Selling e-books, online courses, templates, presets — products with zero reproduction costs.

Pros: Highest margins (80–95%), scalability, passive income. Cons: Requires expertise and time to create the product. Platforms: Gumroad, Udemy, your own website.

6. Your Own Online Store

Full control over brand, pricing, and customer experience. Requires more work but offers the greatest potential.

Pros: No platform commissions, brand building, full control. Cons: Requires traffic (marketing), more technical work. Tools: Shopify, WooCommerce, Shoper (Polish platform).

From Zero to First Sale — A Step-by-Step Plan

Week 1: Niche Selection and Research

How to find a niche:

• Check the most popular categories on Allegro (Trends, Bestsellers)
• Use Google Trends for interest analysis
• Look for products with low competition and stable demand
• Avoid seasonal products when starting out

Criteria for a good niche:

• Minimum 30% margin after all costs
• Lightweight and small product (low shipping costs)
• Repeatable demand (not a one-time trend)
• Ability to differentiate (unique features, better description, better service)

Week 2: Sourcing

Product sources in Poland:

• Online wholesalers: Hurtownia.pl, Hur.pl, BigBuy
• Polish manufacturers — direct contact
• Trade fairs (e.g., Targi Kielce, Targi Poznańskie)
• Store liquidations and wholesale clearances

Importing from abroad:

• AliExpress / 1688.com — products from China (watch out for customs and VAT)
• Sample before placing a larger order
• Minimum order: usually 50–200 units

Week 3: Creating Listings

Elements of an effective listing:

Photos (most important!):

• White background for the main photo
• Minimum 5 photos from different angles
• Lifestyle photos (product in use)
• Infographics with dimensions and features

Title:

• Contains the main keyword
• Clear and specific
• Example: "Bamboo desk organizer | 5 compartments | natural | 25x15 cm"

Description:

• Benefits before features
• Bullet points for key information
• FAQ in the description (sizes, material, how to use)
• Call to action at the end

Week 4: First Orders and Optimization

Order fulfillment:

• Ship within 24 hours of the order
• Include a business card or thank-you note
• Use quality packaging
• Offer InPost Paczkomaty (85% of Poles prefer this option)

Collecting reviews:

• Request a review 3-5 days after delivery
• Respond quickly to negative reviews
• Reviews build trust and platform ranking

Costs of Running an Online Sales Business

One-time (startup):

• First products for sale: 500–5,000 PLN
• Product photos: 0 PLN (DIY) – 500 PLN (professional)
• Logo and branding: 0 PLN (DIY) – 1,000 PLN

• Accounting: 200–500 PLN/month with a registered business

Legal and Tax Aspects

When do you need to register a business (działalność gospodarcza)? Occasional sales of your own belongings do not require a DG. However, regular sales with intent to profit — even on a small scale — require registration.

Tax forms for a registered business (DG):

• Ryczałt 3% — on goods sales (most favorable for trading!)
• Ryczałt 8.5% — on services
• Progressive tax scale 12%/32% — on income
• Flat tax 19% — on income

VAT:

• Subjective exemption up to 200,000 PLN annual turnover
• After exceeding — mandatory VAT registration
• 23% VAT on most products

Fiscal cash register (kasa fiskalna):

• Exemption up to 20,000 PLN in sales to individuals annually
• After exceeding — mandatory cash register

Invoicing:

• Mandatory for B2B sales
• Platforms like iFirma and Fakturownia automate the process

Scaling — From Side Hustle to Business

When your online sales consistently generate 3,000–5,000 PLN/month, you can think about scaling:

Automation:

• Baselinker for managing orders from multiple platforms
• Automatic invoice generation
• Inventory management system

Delegation:

• Packing and shipping: hire a student or use fulfillment services
• Customer service: virtual assistant (30–50 PLN/hour)
• Product photography: external photographer

Marketing:

• Allegro Ads and Google Ads
• Social media (Instagram, TikTok for visual products)
• Newsletter for returning customers

Tracking Online Sales Finances

As sales grow, tracking profitability for each product and channel becomes critical. Freenance helps categorize sales revenue, platform fees, and inventory costs, giving you a clear picture of which products and platforms generate the most profit.

Common Beginner Mistakes

1. Too many products at the start — begin with 3-5 products, master them, then expand.

2. Ignoring shipping costs — include them in the price or offer free delivery above a certain amount.

3. Poor photos — this is the absolute number one factor in online sales. Invest time in good photography.

4. No competitor analysis — check what the best sellers in your category are doing.

5. Neglecting customer service — fast responses and problem-solving build reputation.

6. No margin calculation — before introducing a product, calculate ALL costs: purchase, commission, shipping, packaging, returns.

Summary

Selling online is one of the most accessible additional income sources in Poland. You can start literally for 0 PLN (by selling your own things) and gradually build a profitable business. The key is consistency, good customer service, and continuous listing optimization.

Regardless of the model you choose — reselling, dropshipping, or your own store — the most important thing is to start. The first step is always the hardest, but each subsequent sale builds your experience and confidence in the world of e-commerce.
