Building an online store is one of the biggest business decisions an entrepreneur can make – and one of the most expensive ones if you start it the wrong way. In this guide, we walk through all the key decisions you need to make when creating an online store: platform, budget, development time, and the most common mistakes.
Before development: business questions you need to answer
Many entrepreneurs start by choosing a platform right away – but the right order is the reverse. Before making a technical decision, you need to answer the business questions:
- Product catalog: How many products? Are there variants (size, color)? Do the products change frequently?
- Sales geography: Only in Estonia or abroad as well? Do you need multiple currencies and languages?
- Inventory management: Does it need to integrate with a warehouse system (Erply, Merit, RMS)?
- Payment solution: Bank links (Estonian direct bank payments), card payments, installment payments (Indivy, Testlio)?
- Delivery: Omniva, DPD, Itella SmartPost – do parcel lockers need to work automatically?
The answers to these questions determine which platform is the right fit – not the other way around.
Platform comparison in 2026
WordPress + WooCommerce – the best choice for most Estonian companies
WooCommerce is the world’s most widely used e-commerce platform (~40% of the global market). In Estonia, it is also the most popular choice for both small and mid-sized online stores.
Best for: 10–5,000 products, local market, standard payment solutions, Estonian-language admin
Budget: A minimal professional solution from €3,500–5,000
Pros: Flexible, many Estonian developers, good plugins (Omniva, DPD, Maksekeskus integrations)
Downside: Larger catalogs (10,000+ products) slow down if not configured properly
Shopify – a fast start, but limitations as you grow
Shopify is a SaaS platform (you pay a monthly fee) that is a great starting point for startups with a small budget. It requires no technical expertise; you can set up a store in a day.
Best for: Small product range, international sales, dropshipping
Budget: From €29–79/month + a percentage per transaction
Pros: Quick launch, built-in hosting and security, good mobile apps
Downside: Limited customization options, Estonian bank links require a separate solution, high long-term cost
Adobe Commerce (formerly Magento) – for large enterprises only
Magento has become Adobe Commerce and is aimed at large enterprises with 50,000+ products and international operations. Development is complex and expensive – a minimal project starts at €30,000+ and requires a specialized team.
For most Estonian companies, this is not a realistic option.
Budget and development time – realistic numbers for 2026
Estonia has plenty of developers, with hourly rates ranging from €20–120/h. The cheapest is not necessarily the best – look at the portfolio and ask for references.
- Simple online store (up to 100 products, standard features): €3,500–7,000 | 4–8 weeks
- Medium-complexity online store (inventory management, integrations): €7,000–15,000 | 8–16 weeks
- Complex online store (multilingual, B2B features, ERP integration): €15,000–40,000 | 4–8 months
Important: The budget must also include SEO setup, Google Analytics 4 + Google Ads conversion tracking, and content creation. An online store without marketing doesn’t sell.
The 5 most common mistakes when building an online store
- Choosing a platform by price rather than by need – the cheapest solution often ends up costing more when everything has to be rebuilt a few years later
- Forgetting SEO during development – URL structure, titles, and loading speed must be planned from the start, not added later
- Not testing the mobile version enough – more than 60% of online store visitors use a mobile device
- Not optimizing images – large image files slow down the store and reduce the conversion rate
- Product descriptions copy-pasted from the supplier – duplicate content seriously harms SEO
When is an online store finished?
An online store is never completely “finished” – it is a living environment that needs continuous development, marketing, and optimization. A successful online store requires investment in both development and ongoing monthly marketing (SEO, Google Ads, email marketing).
