For businesses that want to sell products or services over the internet, preparing a website is not enough. An e-commerce website is a complete sales system: it presents products, takes orders and payments, manages stock and shipping, and has to be found, trusted and measured. This guide takes you through setting one up step by step. It is written with Türkiye in mind, so the legal notes refer to Turkish practice; check current rules with your accountant.
What Is an E-Commerce Website?
A digital sales platform where products or services are displayed, ordered and paid for online. For the wider picture of starting a business, read how to start e-commerce.
How Does an E-Commerce Site Work?
A visitor browses categories, opens a product page, adds items to the cart, enters delivery details and pays. The system confirms the order, informs the warehouse or supplier, updates stock and sends shipping information to the customer. Behind this, the store manager uses an admin panel to manage products, orders and reports.
What Should Be Decided Before You Build?
Decide What to Sell
Choose a product or service with real demand, a healthy margin and a supply you can rely on.
Define Your Target Audience
Know who you are selling to and what they expect. See our guide on the target audience.
Choose a B2C or B2B Model
B2C sells to individual consumers; B2B sells to businesses, often with special prices and payment terms. Read what is B2C and the B2B business model.
Decide Between a Stocked and Stockless Model
- Stocked e-commerce: you buy and hold products; more control and margin, more capital and risk.
- Stockless e-commerce: a supplier ships; lower investment but less control. See dropshipping.
Calculate the Starting Budget
Include the platform, domain and hosting, design, product photography, stock, payment fees, packaging, marketing and a reserve. For help, read the capital needed for e-commerce, and see our guide for Black Friday and New Year campaigns. A percentage calculator helps with margin and discount calculations.
Do You Need a Company to Set Up an E-Commerce Site?
For regular commercial sales, tax and invoicing obligations arise, and the right business structure should be evaluated with an accountant. See how to set up a company.
Legal Points to Watch
The Electronic Commerce Law sets rules on information, orders and commercial messages. Alongside it come consumer law, distance contracts and the KVKK (data protection). Show your business details, publish the required legal texts and handle consent properly.
Is ETBİS Registration Needed?
ETBİS is the government’s e-commerce information system; whether you must register depends on your activity and the current exceptions. See what is ETBİS.
How to Plan the e-Invoice and e-Archive Process
Depending on your status you may need to issue e-invoices or e-archive invoices; read what is an e-invoice. Integrating invoicing with your store saves time.
How to Choose E-Commerce Software
Software is the engine of the store; read what is e-commerce software for a detailed comparison.
| Option | Strength | Trade-off |
|---|---|---|
| Ready-made packages | Fast, low technical burden | Less flexibility |
| Open-source platforms | Flexible, no license fee | You manage hosting, security, updates |
| Custom software | Fits specific processes and scale | Highest cost and time |
Choosing a Domain, Hosting and SSL
- Domain: short, memorable, matches the brand and is easy to spell; see how to choose an SEO-friendly domain name.
- Hosting: needed if you run your own software; ready platforms often include it. See what is hosting.
- SSL certificate: required (HTTPS) for secure data transfer and trust at checkout.
What Should the Page Structure Look Like?
Core pages: home, category pages, product pages, cart, checkout, account, order tracking, about, contact, shipping and returns, FAQ and the legal pages.
How to Build the Category Structure
Keep it logical and shallow: main categories, subcategories and, where useful, filters. Think the way your customers think, and use their words.
How Should the Design Be?
Clean, fast and trustworthy, with clear navigation, a visible search box and obvious calls to action. For design principles, read how to design an e-commerce website.
Why Is Mobile Compatibility Important?
Most shoppers browse on phones, so every step from product page to payment must work well on small screens. See responsive web design.
Preparing Product Pages
- What a product page should contain: title, price, images, description, variants, stock and delivery information, reviews and a clear add-to-cart button.
- Product photos: sharp, consistent and from several angles.
- Product descriptions: unique, benefit-led and scannable.
- Product URLs: short and readable; see what is an SEF link. The SEO URL generator can help.
- Stock and variants: manage sizes, colors and stock levels accurately.
- Barcodes and GTIN: product identifiers matter for marketplaces and Google Shopping; read what is a GTIN.
- XML product integration: supplier catalogs can be imported automatically; see XML dealership.
Setting Up Payment Infrastructure
How Do You Get a Virtual POS?
Apply to a bank or payment institution with your company and website details. Payment institutions can be a faster alternative for smaller businesses.
What Should the Payment Page Look Like?
Short, secure and clear, with the total cost, accepted methods and security badges visible, and a guest-checkout option.
Setting Up Shipping
- Shipping integration: connect your carriers to automate labels, tracking numbers and status updates as order volume grows.
- Shipping fees: decide whether to charge, include or offer free shipping above a threshold.
- Returns and exchanges: define a clear, simple process and publish it.
How Is E-Commerce Site SEO Done?
Make your pages findable: optimize category pages, write unique product content and avoid technical issues. For the full approach, read e-commerce SEO. Set up Google Search Console and Google Merchant Center early.
Analytics and Conversion Measurement
Install Google Analytics and Google Tag Manager before launch and track the key events: product views, add to cart, checkout start and purchase.
How to Improve Site Speed
Compress images, limit heavy scripts and check regularly with Google PageSpeed Insights.
Increasing the Conversion Rate
- Show trust elements: reviews, secure payment badges, returns policy and contact details.
- Use strong calls to action; see Call to Action.
- Apply cross-selling; see cross-selling.
- Use on-site marketing; see onsite marketing.
- Prepare landing pages for campaigns; see what is a landing page.

- Remarketing: see what is remarketing.
- Selling through social media: see selling on Instagram.
- Marketplaces alongside your site: many businesses sell on both; see online sales sites.
- Selling abroad: possible with extra planning; read what is e-export.
How to Secure an E-Commerce Site
Use HTTPS, strong passwords and limited admin permissions, keep software and plugins updated, run regular backups, rely on certified payment providers and never store card data yourself.
How to Test an E-Commerce Site
Before launch, test: product pages (images, variants, prices), the cart (adding, removing, coupons), payments (success, failure, 3D Secure), orders (confirmation emails, invoices, stock updates) and mobile (all steps on real devices).
E-Commerce Site Setup Cost
The cost depends on the approach: platform or license, domain and hosting, design, integrations, photography, payment fees, marketing and ongoing maintenance. Ready packages cost less up front; custom projects cost more but can fit special needs.
How Long Does It Take?
Ready packages: days to a few weeks. Customized projects or custom software: a few months, depending on scope.
