This page explains how to build a fully functional online store for small business in Valencia and across Spain. We cover how e-commerce works, where to start, which stack to choose (Shopify, WooCommerce, Next.js or headless), how to integrate payments and shipping, what it costs and what results it delivers. By a shop we mean not just a simple shopfront, but a real sales machine: fast product search, secure payments, order tracking, mobile functionality, warehouse and CRM integration. That store sells 24/7, runs on autopilot and scales easily. Below is a step-by-step plan, cost and timeline reference, platform and stack recommendations, and answers to common questions. At the end, our "Websites & stores" packages with real prices and related services. ## 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. 1. Review your entire product catalog and categories. 2. Define your target market: age, gender, location, income level. 3. Write 5-10 questions about what your customer is looking for. 4. Look at competitor stores: what you like, what you don't. 5. Choose a platform: Shopify, WooCommerce, Next.js, Medusa or another. 6. List the required integrations: payments, shipping, CRM. 7. Discuss the MVP: the minimum set of features to launch. 8. Get a quote and timeline: usually 21-30 days for a basic shop. ## How much does an online store cost? ### 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. **Levels of online store development** | Level | What is included | Timeline | Who it fits | | --- | --- | --- | --- | | Landing store | 20-50 products, Shopify or WooCommerce, basic design | 21-30 days | Startup, small catalog | | Basic store | 100-500 products, design, payment and shipping integrations | 21-30 days | Small business with growing catalog | | Professional store | 500+ products, headless e-commerce, custom design, full integrations | custom quote | Growing business, many products, complex logistics | ## 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. > > Baymard Institute, Cart abandonment research.

A website is a business card, a shop is a sales machine. A store has catalog, cart, payments, shipping and CRM. A website informs, a store sells. If you have few products so far, the store can start with a small catalogue and grow over time. Every product page is built to be found in search, not just listed. ### Which platform to choose: Shopify, WooCommerce or Next.js? Shopify is fast and simple, everything out of the box, but has limits and extra costs to scale. WooCommerce is more flexible, cheaper, but you need your own infrastructure. Next.js (headless) is maximum flexibility and speed, but needs developers. We recommend the platform based on your needs and budget. ### How many products can a store have? Theoretically, millions. Practically, depends on platform and infrastructure. Shopify works well up to 10,000 products, WooCommerce up to 50,000, headless unlimited. Key is keeping search and filters fast. Before choosing a platform we estimate how many products there will be in a year, not just today. ### How do you integrate payments into a store? We integrate payment gateways: Stripe, Adyen, PayPal, Mercado Pago and others. For Spanish stores Stripe and Adyen are popular. We can integrate multiple payment methods at once: cards, wallets, bank transfers. The money lands in your account directly; the service fee is paid to the provider, not to us. ### What is the timeline for developing an online store? Basic store 50-100 products: 2-3 weeks. Store 100-500 products with integrations: 4-5 weeks. Large store 500+ products with custom design: 6-8 weeks. Timeline depends on data availability and approval speed. Preparing the product pages takes the most time, so it pays to gather photos and descriptions in advance. ### How is the store price calculated? Price comprises development (platform, frontend, backend), design (layout, prototype, markup), integrations (payments, shipping, CRM) and content (product upload, photos, descriptions). Exact quote after a brief session. The quote is broken down by block, so you can see what can be postponed without hurting the launch. Payment and shipping integrations are quoted separately. ### Are hosting and domain included in the store price? No, hosting and domain are paid separately. We help you choose and configure infrastructure and buy the domain, but payments go directly to the provider. Approximate hosting budget: 50-500 EUR/month depending on traffic. Hosting and domain are registered in your name, so the store belongs to you. ### Do you maintain the store after launch? Yes, we offer support packages: technical maintenance, product updates, review moderation, speed and security monitoring. You can manage the store yourself, we help if you have issues. You choose the support format: monthly maintenance or one-off tasks on request. The scope of support is fixed in the contract. ### Do you train the team to manage the store? Yes, after launch we provide training: how to add products, change prices, track orders, answer customer questions. We deliver detailed manuals and video tutorials. Training takes place in your own store, not a demo, so the team works with real products from the start. ### What results will I get from an online store? Results depend on product, target audience, marketing and team work. Average e-commerce conversion usually sits between 1.5% and 3% of traffic into orders; a technically polished store with fast loading and a simple checkout works steadily at the upper end. The store sells 24/7 and expands geography, which helps many clients grow turnover in the first months after launch.
