E-commerce is the most important sales channel for many businesses. A well-executed store grows sales, strengthens the brand and expands the customer base.

This guide covers the most important steps when planning to set up an e-commerce store.

We have built e-commerce stores across many platforms since 2006. You'll benefit from extensive experience with e-commerce, usability research and design.

Broad experience across systems

We have worked with the e-commerce systems listed below. We know their features, strengths and weaknesses.

1. Planning and strategy

A successful e-commerce store starts with good planning. Before technical decisions, it's important to clarify:

Business idea

What are you selling and to whom?

Target audience

What needs do your customers have?

Competitive edge

How do you stand out - price, quality, delivery speed or specialty products?

Budget and goals

Allocate enough resources for setup, marketing and maintenance.

2. Choosing an e-commerce platform

The platform largely determines how the store works, scales and evolves in the future. Four recommended platforms are:

Magento 2

A powerful and scalable platform for large and complex e-commerce stores and B2B. A good choice for an extensive, customized solution.

WooCommerce

A WordPress plugin that turns a site into an e-commerce store. Flexible, extensible with thousands of plugins and cost-effective especially for SMBs.

Shopify

A popular SaaS service that gets a store up and running fast without major technical investment. User-friendly and modern, but more limited in certain customization areas.

MyCashflow

A Finnish option designed specifically for Finnish merchants. Easy to integrate with local payment and logistics providers.

No worries - we can recommend the right platform once we know your business and customers' needs and requirements clearly enough.

3. Usability and design

The customer's purchase experience determines whether they come back and recommend your store. Pay attention to:

  • Clear structure and navigation
  • Responsive on every device
  • Visually appealing and on-brand
  • Conversion-optimized, simplest possible purchase path

4. Payments and logistics

Working payment methods and smooth deliveries are the backbone of e-commerce. In Finland, the most common solutions are:

Payment methods

Paytrail, Klarna, Stripe and PayPal

Delivery

Posti, Matkahuolto, DB Schenker and pickup points

Integration with logistics and payment providers should be considered from day one.

5. Marketing and SEO

Without marketing an e-commerce store does not reach customers. The most effective methods are:

  • Search engine optimization: make sure your store shows up on Google for the right terms
  • Content marketing: blogs, guides and customer stories drive traffic
  • Social media: Facebook, Instagram and TikTok support sales
  • Email marketing: newsletters and automations keep customers engaged

6. Maintenance and development

An e-commerce store is never completely finished. A successful merchant invests in continuous development:

  • Update the platform and plugins regularly
  • Take care of security
  • Monitor analytics and run A/B tests
  • Continuously optimize usability and conversion

Summary

Setting up an e-commerce store requires planning, the right platform and continuous development.

  • Magento suits businesses that need flexibility and features.
  • WooCommerce and Shopify suit SMBs.
  • MyCashflow is a great and easy-to-use basic package for an e-commerce store.

When you combine quality content, good usability and active marketing, your e-commerce store becomes a profitable sales channel for the long term.

We're happy to help with anything related to setting up an e-commerce store.

Shopify

Shopify is an internationally popular SaaS e-commerce platform that gets you up and running fast without your own server or version upgrades. It's especially suitable for SMB merchants who want a modern, easy-to-maintain store without a large technical investment.

Shopify's strengths include fast launch, an extensive app ecosystem and strong marketing tools. Shopify Markets enables multilingual sales in multiple currencies under one admin. Limitations - monthly fees, transaction fees with external payment services and certain B2B features only on Plus - should be assessed before choosing.

B2B e-commerce

We also build Business-to-Business e-commerce stores. For example, Magento is well suited as a B2B platform due to its extensibility.
