How do you start building an online store?.

Start with an audit: products, target market and platform choice

Before writing code, you need to understand what you sell, who your customer is, which countries you ship to. Based on that, we choose the platform. For startups with non-standard needs, headless e-commerce on Next.js. For small business with typical needs, Shopify or WooCommerce. Then we create a technical brief: product catalog, pages (home, product, cart), integrations (payments, shipping, CRM). Next comes design, frontend and launch.

How much does an online store cost?.

Checkout step in online store: cart, shipping, payment
Simple and fast checkout reduces cart abandons and increases conversion.

Price depends on platform, product count, integrations and design

The cost of an online store comprises platform development, design, integrations (payments, shipping, CRM) and content (products, descriptions, photos). On ready-made platforms (Shopify, WooCommerce) it is cheaper and faster. On headless e-commerce (Next.js, Medusa) it is more expensive, but more flexible and faster. Prices below are in the "Websites & stores" section; volume and timeline reference in the table.

How do you increase conversion and sales in an online store?.

Speed, mobile, simple checkout and reviews: that works

Store conversion depends on five factors: load speed (under 3 seconds), mobile interface (a significant share of traffic comes from phones), simple checkout (up to 3 steps), price and shipping visibility with no hidden fees, reviews and ratings (social proof). According to the Baymard Institute, the average cart abandonment rate is 70.19%, and its main causes tie directly to these factors: high final cost and a long checkout. Stores that address these five points convert noticeably better. We build all this into the development process.

Expert opinion

«The average documented online shopping cart abandonment rate is 70.19%. The main reasons are extra costs being too high (shipping, tax, fees), being forced to create an account and a checkout process that is too long or complicated.»
