10 steps to build an ecommerce website
- Product and target customer: define what you will sell, to whom and at what price
- Company and tax: sole proprietorship or limited company, tax registration; talk to your accountant about e-fatura/e-arşiv (Turkish e-invoice and e-archive invoice)
- Domain and hosting: a domain that fits your brand, an SSL certificate and a fast server
- Platform choice: off-the-shelf package or custom software (compared below)
- Product structure: categories, variants (size, color, dimensions), stock and pricing rules
- Payments: PayTR, iyzico or a bank virtual POS; 3D Secure and installments
- Shipping: carrier agreement and integration, labels and tracking
- Legal pages: distance sales agreement, pre-contract information, return policy, KVKK (Turkish data protection law) and cookie notices
- SEO and speed: SEO-friendly product pages, structured data, fast loading
- Launch and marketing: Google Merchant Center, social media, marketplaces
Off-the-shelf package or custom ecommerce software?
- Off-the-shelf package (SaaS): quick start; monthly fees, sales commission or module fees; design and features limited to the package; data and code stay on the platform
- Custom ecommerce software: product structure, pricing rules and integrations built for your business; unlike off-the-shelf ecommerce packages, custom software has no sales commission or per-user monthly license; the source code and customer data belong to you.
- When to choose custom software? when you have pricing by size/variant, B2B dealer pricing, ERP/accounting connections, custom campaign rules or high order volume
