Ecommerce website development is the most profitable move for a commercial business looking to increase its revenue. A modern online store operates 24/7, attracts customers from all over Greece, and automates your sales. Discover the costs, technical requirements, and implementation steps to succeed in the digital market.

Key takeaways

• Your online store has no geographical limits, instantly expanding your customer base.

• Loading speed (Core Web Vitals) at checkout is crucial for completing a purchase.

• Integration with an ERP, banks, and courier companies drastically reduces management time.

• Proper SEO structure from day one ensures free organic traffic from Google.

What is ecommerce website development?

Ecommerce website development is the technical process of building an online platform where users can browse products, add them to a cart, and pay securely over the internet.

For a digital store to succeed today, a simple design is not enough. A robust infrastructure is required. At Wechevo, we develop online stores that load instantly and offer a flawless shopping experience on mobile devices. Using top-tier design tools like Elementor, we create custom, attractive environments that keep the user engaged, while simultaneously maintaining clean code for search engines.

What is the ecommerce website cost 2026?

The ecommerce website cost 2026 for a small to medium-sized business in the Greek market averages between €1,500 and €3,500 (plus VAT), depending heavily on the product volume and the required technical automations.

The requirements of every business are unique, which is why the cost is adjusted accordingly. For instance, a boutique with 50 handmade items has entirely different operational needs than a clothing warehouse with 5,000 SKUs and multiple size variations.

Beyond the initial build cost, you must factor in website hosting on powerful servers (ranging from €200 to €500/year) to withstand high traffic during promotional periods like Black Friday. If the upfront cost seems high, you can always explore the solution of a subscription-based store.

What integrations are necessary for an online store?

Essential integrations include electronic payment gateways (Banks, Viva Wallet, Everypay), courier company bridges for automated voucher issuance (ACS, Geniki Taxydromiki), and modern invoicing systems.

An online store should run on autopilot as much as possible.

• Payments: The customer must be able to pay securely via credit card, IRIS, or Apple/Google Pay.

• Shipping: Integration with courier companies and solutions like BoxNow allows for automatic calculation of shipping costs based on postal code and weight.

• Accounting: Direct integration with the AADE myDATA system via an ERP ensures the legal and rapid issuance of retail receipts and invoices.

• Marketplaces: Creating an XML feed is mandatory for displaying your products on platforms like Skroutz, BestPrice, or Google Shopping.

Step-by-step: How to create ecommerce website correctly?

Ecommerce website development follows a strict methodology to ensure that there will be no technical glitches when customers actually start ordering.

1. Requirements Analysis: We examine your products, competition, and categories. We define the keyword strategy and the navigation structure (mega menu).

2. Design (UX/UI): We create visual drafts focusing on a seamless checkout process. The goal is for the user to complete their purchase in fewer than 3 steps.

3. Technical Implementation: We build the platform, import the products (in bulk or manually), and configure search filters (price, size, color).

4. Integrations and Payments: We install and test the payment terminals (e-POS) and the shipping company plugins.

5. AEO & SEO: We apply strict SEO optimization. We write unique product descriptions, properly configure Meta Tags using top tools (like Rank Math), and optimize all images.

6. Testing: We execute virtual orders, test mobile loading speeds, and verify the confirmation emails received by the customer.

7. Training & Go Live: We deliver the store, train you on order management, and launch Google Ads campaigns to bring in the first sales.

How does ecommerce website development affect your sales?

Professional ecommerce website development turns simple visitors into buyers (increasing the conversion rate) by offering speed, security, and trust, thereby drastically reducing abandoned carts.

According to the official Core Web Vitals specifications by Google, if a store takes more than 3 seconds to load, over half of the visitors will abandon it. The architecture of the e-shop, clear "Add to Cart" buttons, and proper descriptions (with sizing guides, clear photos, and FAQs) "persuade" both the algorithm and the user.

Additionally, it is important to know that you can leverage funding. The Greek government frequently announces an ESPA subsidy for the digital transformation of businesses, which can cover a significant portion (often over 50%) of the development expenses.

From our experience: Common mistakes that cost sales

From our experience in developing e-commerce applications, the most common mistake is creating an e-shop with "heavy" images and a complicated checkout that frustrates and discourages the user.

Other critical mistakes we frequently see in the Greek market include:

• Absence of an SSL certificate (security protocol), resulting in the browser displaying a "Not Secure" warning at the checkout.

• Hidden fees (like unexpected shipping costs) that suddenly appear at the final step, driving the customer away.

• Using generic, cheap product descriptions (copy-pasted from the supplier), which is strictly penalized by Google (Duplicate Content) based on the official ecommerce SEO guide.

• Unoptimized on-site search, where the user cannot find the product they are looking for if they make even a single spelling mistake.

What to do now?

If you want to dynamically launch your online sales, or if your current online store is slow and failing to bring in orders, proper technical intervention is the only way forward.

FAQ

Can I sell wholesale (B2B) and retail (B2C) simultaneously?

Yes, proper ecommerce website development allows for the creation of different user roles. Regular visitors will see retail prices including VAT, while approved merchant-partners, upon logging in, will automatically see wholesale prices and the corresponding discounts you have assigned to them.

Do I need a shipping company to launch my store?

To ship products, you need a contract with at least one courier company. During the development of the e-shop, we install the specific software (plugins) of your chosen company so that printing shipping vouchers can be done automatically from your site's backend with a single click.

What do I need to accept credit card payments?

To accept payments, an active professional bank account is required. Subsequently, we apply to the bank (or payment institutions like Viva Wallet) for the issuance of a digital terminal (e-POS). We handle the complete technical integration and the necessary test transactions to ensure proper functionality.

Is ERP integration mandatory?

No, for small e-shops with a low volume of orders, inventory management can be easily handled within the platform (e.g., WooCommerce). However, if you have a physical store, thousands of SKUs, or a high daily volume of orders, integration with an ERP (Enterprise Resource Planning) system is essential to prevent inventory syncing issues and automate invoicing.
