E-commerce (electronic commerce) is a sales format in which all stages of interaction with the customer take place online: browsing products, making a choice, payment, order confirmation, and delivery. Successful e-commerce brings together marketing, technology, logistics, and customer service — and all of that converges in one central hub: the website.
A product-based business is a business model built around selling physical goods. These can include anything with shape, weight, and packaging — clothing, cosmetics, electronics, handmade items, food, children’s goods, kitchenware, accessories, and more. Many entrepreneurs start with a product-based business when looking for a simple way to enter the online market. Launching a product-based business from scratch is especially popular: small product batches, testing the niche, investing in advertising — and getting the first sales through social media or marketplaces.
However, once it comes to scaling, stability, or brand recognition, the business needs its own sales tool — a functional website. A site becomes the foundation for advertising, analytics, search engine optimization, and trust-building. It enables you to build a logical site architecture, set up product cards, connect payment systems, inventory tools, analytics, SEO, and CRM — everything that creates a strong, controllable online business.
For many entrepreneurs, a product-based business starts with an Instagram page or a marketplace profile. It’s a fast launch — but not a stable strategy. Social media platforms change their algorithms, block accounts, and restrict organic reach. Marketplaces control your communication with clients, charge commissions, and manage access to your audience. A website, on the other hand, is your own space — you set the rules.
a showcase for all your products;
an analytics hub for tracking conversions and user behavior;
a foundation for promoting your site through SEO, contextual ads, and retargeting;
a CRM and lead collection point — with forms, customer accounts, and confirmation emails.
manage traffic — launch ads for specific product or category pages;
automate the ordering process — from cart to payment;
create a clear site architecture that guides users logically from browsing to buying;
gather and analyze data: traffic sources, bounce rate, average check, repeat purchase frequency.
The key advantage is limitless scalability. You’re not tied to platform restrictions or a fixed number of product listings, as is often the case with marketplaces or website builders. You control everything — from structure and design to speed and promotion. Which means — you control your profit.
An online store isn’t just a site with products — it’s a complete system where every element impacts sales. If even one component is underdeveloped, conversions drop, bounce rates rise, and customer trust fades. That’s why the technical specification for website development must include a full set of functional and UX solutions that make up a high-performing e-commerce platform.
Well-defined categories and subcategories, filters, and sorting by price, new arrivals, or rating. Users must easily find what they’re looking for — especially when the product range is wide.
Photos, descriptions, specifications, price, availability, variations (color, size), reviews. Everything needs to be clearly presented — especially on mobile devices.
Minimal steps: add to cart → enter contact info → select delivery and payment. No required registration, complicated forms, or reloads.
Connection with Wayforpay, LiqPay, Fondy, Nova Poshta, Justin, etc. The customer should instantly see delivery options and complete payment online without redirects.
The site must perform flawlessly across all devices — smartphones, tablets, laptops. In e-commerce, 70–80% of traffic comes from mobile.
Automated meta tags, sitemap generation, clean URLs, caching, and image optimization. This forms the technical base for search engine optimization and fast load times.
Integration with Google Analytics, Facebook Pixel, Hotjar, Calltouch, email/SMS platforms. All customer data is at your fingertips: what they buy, how often, and when they return.
Each of these components isn’t just a feature — it’s a building block in your sales system. At COI.UA, we treat every project not as a page layout, but as the construction of a tool that actually sells — efficiently, reliably, and at scale.
The Ukrainian market has its own specific features — and that must be taken into account when launching a website. Platforms that perform well in the US or EU may not support local delivery services, payment systems, or currencies. That’s why when launching a product-based business from scratch in Ukraine, it’s crucial to build on tools that actually work in our environment.
Payment services: Wayforpay, LiqPay, Fondy. Delivery: Nova Poshta, Meest, Justin. The site should support them both technically and with a proper UX (API, tracking, address forms).
Support for UAH, USD, and EUR. The ability to switch interface languages. This is especially important for brands planning to sell abroad or operate in multiple regions.
Your e-commerce platform must be technically prepared for running ads in Google Shopping, Meta Ads, and TikTok Ads. This includes a proper site structure, search engine optimization, UTM tagging, and landing pages adapted to campaigns.
Ukrainian customers are used to browsing by category and sorting by price. The structure must be logical, concise, and intuitive — otherwise, you risk losing conversions.
Most purchases happen on smartphones. If your site doesn’t work on mobile — it doesn’t work at all. Mobile adaptation must be uncompromising: fast loading, large buttons, clear text, and thoughtful UX.
The technical foundation, UX solutions, analytics, and site promotion strategy should all be embedded during the planning stage. At COI.UA, we take into account the specific needs of Ukrainian product-based businesses: we adapt platforms, connect local services, and build architectures that are both clear and effective for your audience.
Even with a quality product, you can lose the majority of potential customers — if your website is built without meeting key e-commerce requirements. This is especially relevant for small businesses or those launching a product-based business from scratch. At COI.UA, we often start collaborations by fixing these issues — and each one costs the business traffic, sales, and reputation.
Beautiful visuals are great — but if the site is slow, unfit for advertising, or poorly optimized for search engines, it won’t sell. It’s not just about aesthetics — it’s about functional site architecture.
Up to 80% of e-commerce traffic comes from mobile. If your site isn’t mobile-friendly, users will simply leave. Responsive web design isn’t a bonus — it’s a baseline requirement.
Users won’t wait: if your site loads slowly, buttons don’t work, or the interface lags — sales won’t happen. This is a matter of code quality, server architecture, and caching.
If users are forced to register, fill in too many fields, or struggle to finalize a purchase — they’ll leave. E-commerce should drive conversion in 2–3 clicks.
Without properly structured URLs, meta tags, a sitemap, and page hierarchy, search engine optimization simply won’t work. And SEO is a long-term source of free traffic.
If the website is built “by eye” — with no clear function map or goals — it will start falling apart after the first wave of advertising. That’s why we begin every project with a detailed technical specification, tailored to your product, audience, and promotion plans.
Avoiding these mistakes already brings you 50% closer to success. And proper implementation ensures confident scaling — whether you’re just entering the online space or expanding an established brand.
One of the first decisions you’ll need to make is where exactly to launch your site. The choice of platform directly affects the potential of your e-commerce business — from launch speed to scalability, analytics, and SEO.
