Creating an online store happens in eight steps: project scoping, choice of e-commerce platform, catalog, payment, shipping, legal compliance, launch and then acquisition. Expect 8 to 14 weeks for a professional project run with an agency.
According to Fevad, French shoppers spent more than €175 billion online in 2024, and growth continues in 2026.
NEXUS SYNERGY, a WordPress and e-commerce agency with more than 150 sites delivered, breaks down each step with the budgets and timelines observed on our WooCommerce projects.
To create an online store that actually sells, you have to move in order: business scoping, platform choice, catalog building, payment setup, shipping logistics, legal compliance, launch, then traffic acquisition. A professional project takes 8 to 14 weeks and starts at around $8,000 with an agency.
This guide is built on field experience, not theory. At NEXUS SYNERGY, we support SMBs that want to build a profitable online store, with more than 150 sites delivered and an average Lighthouse score above 95. Each step below reflects the durations, budgets and mistakes we see on real e-commerce projects.
What should you scope before creating an online store?
Business scoping always comes before choosing the tool. An online store rarely fails because of its technology: it fails because the offer, the audience or the margins were never written down in black and white. In our view, this first step determines 80% of the final result.
The market itself remains strong. French shoppers spent more than €175 billion online in 2024, and more than 40 million of them buy online, as shown by the 2026 key figures published by Fevad. But a huge market also means huge competition. Hence the value of scoping seriously before investing.
- Offer and positioning: what are you selling, to whom, and why buy from you rather than elsewhere?
- Real margins: purchase price, shipping costs, payment fees, returns. A gross margin below 50% leaves little room for advertising
- Target average order value: it determines your free-shipping threshold and your acquisition budget
- Realistic conversion rate: between 1 and 3% for a young store, rarely more in the first year
- Target volume: how many orders per month to cover your fixed costs?
A simple exercise delivers the verdict: divide your monthly revenue goal by your average order value, then by a 1.5% conversion rate. You get the traffic you will need to generate. When that number looks out of reach, better to rework the offer now than six months after launch.
Which platform should you choose for your online store?
Three families of solutions let you create an online store: turnkey SaaS platforms (Shopify, Wix), open source CMSs (WooCommerce, PrestaShop) and custom development. The right choice depends on your budget, your need for scalability and your tolerance for vendor lock-in.
Our position is clear, because we verify it project after project: for an SMB that wants to keep control of its data, its SEO and its recurring costs, WooCommerce on WordPress remains the best freedom-to-price ratio. WordPress powers 43.5% of the world's websites (W3Techs, 2026), which guarantees an ecosystem of extensions, hosts and developers without equal. It is the technology we deploy in our WooCommerce store development service, with projects starting at $8,000.
- Turnkey SaaS: quick to launch, but a subscription for life, possible sales fees and capped customization
- WooCommerce: you own the site and the data, controlled costs, total freedom over SEO and design
- Custom build: reserved for very specific business models, from $30,000, rarely justified for a first store
Let's be honest about the limits: WooCommerce demands quality hosting and serious maintenance, otherwise performance degrades. That is the price of freedom. When the project is built properly from the start, this point is easy to manage.
How do you build a product catalog that converts?
Your catalog is your silent salesperson. A complete product page answers questions before the customer asks them: material, dimensions, delivery times, returns, reviews. Stores that copy their supplier's descriptions stack up two handicaps, duplicate content that Google ignores and copy that convinces nobody.
Every product page therefore deserves real editorial work. Write unique, benefit-driven descriptions, plan 3 to 5 photos per product on a consistent background, and structure the site tree so that every item stays reachable within 3 clicks from the homepage.
- Product title: name + differentiating attribute + use case, written with search in mind
- Description: 150 to 300 unique words, benefits first, specifications second
- Visuals: compressed WebP images, zoom, real-life context shots
- Social proof: verified customer reviews from the very first sales
- Structured data: price, stock and ratings visible directly in Google
Loading speed is part of the catalog, even if it is often forgotten. At NEXUS SYNERGY, we aim for an LCP under 1.5 seconds on every product page, a standard we detail in our web performance service. The NovaTech case shows what is at stake: by going from 6.2 seconds to 0.9 seconds of load time, its conversions grew by 127% in 3 months.
What budget and timeline for creating an online store?
Creating a professional online store costs from $8,000 with an agency and takes 8 to 14 weeks, from the scoping workshop to going live. About half of our projects are actually rebuilds of stores launched too fast, with a systematic 301 redirect plan to preserve the existing SEO.
The table below lays out the eight steps with their duration, their share of the budget and the mistake we fix most often. The ranges correspond to a WooCommerce project run with a professional partner, with a catalog of 50 to 500 products.
| Step | Typical duration | Share of budget | Common mistake |
|---|---|---|---|
| 1. Scoping and business plan | 1 to 2 weeks | 0 to 5% | Choosing the tool before the offer |
| 2. Platform choice | 1 week | 0% (free audit) | Deciding on price alone |
| 3. Design and development | 4 to 6 weeks | 40 to 50% | Piling on options in V1 |
| 4. Catalog and product pages | 2 to 3 weeks | 15 to 20% | Copying supplier copy |
| 5. Payment | 2 to 4 days | 5% | A single payment method |
| 6. Shipping and logistics | 1 week | 5 to 10% | Shipping costs discovered at checkout |
| 7. Legal compliance | 1 week | 5% | Terms of sale copied from a competitor |
| 8. Launch and acquisition | 1 to 2 weeks, then ongoing | 15 to 25% | Waiting for traffic with no SEO or ads |
Two lessons stand out from this table. First, development represents only half the budget: the catalog, the legal work and acquisition weigh as much as the code. Second, short timelines come from solid scoping, never from skipping steps. Our e-commerce portfolio shows what this method delivers on real projects, with a free initial audit and a firm quote within 24 hours.
How do you set up payment and shipping for your online store?
Payment and shipping form the duo that makes or breaks trust. Around 70% of carts are abandoned before checkout according to the Baymard Institute, and fees discovered at the last moment remain the most cited cause. In other words, transparency pays more than any marketing trick.
On the payment side, offer at minimum card payment via Stripe or PayPlug, plus PayPal for cautious buyers. 3-D Secure is mandatory in Europe, and installment payments noticeably increase the average order value above $100. Expect a fee of 1.5 to 2.9% per transaction depending on the provider.
- Card payment: essential, via Stripe, PayPlug or your bank's module
- PayPal: reassures new customers, despite higher fees
- Installment payments: worthwhile once the average order value exceeds $100
- Home delivery: Colissimo or a private carrier, with tracking on every order
- Pickup points: Mondial Relay or Chronopost Shop2Shop, often 30 to 40% cheaper
For shipping, display the costs from the product page onward and set a free-shipping threshold consistent with your average order value, generally 20 to 30% above it. When the average order value reaches $60, free shipping at $79 mechanically pushes the customer to add one more item.
What are the legal requirements for selling online in France?
Selling online in France requires a precise legal foundation: legal notices, terms of sale, a GDPR-compliant privacy policy, a cookie banner and respect for the 14-day withdrawal right. Ignoring this foundation exposes you to fines, but above all to an immediate loss of buyer trust.
These documents are not legal decoration. Your terms of sale govern your delivery times, your returns and your disputes; they must therefore match how you actually operate. Terms of sale copied from a competitor create commitments you cannot keep, and it is one of the points we systematically check during rebuilds.
- Legal notices: company identity, registration number, host, contact details
- Terms of sale: prices, delivery, withdrawal, legal warranties of conformity
- GDPR: explicit consent, processing register, retention periods (CNIL framework)
- Cookies: a banner where refusing is as simple as accepting
- Consumer mediation: naming a mediator is mandatory for every online merchant
Add to that an appropriate legal structure. Micro-entrepreneur status is enough to test an activity, while a SASU or SARL becomes preferable once volumes and inventory grow. When in doubt, an accountant settles the question in a one-hour meeting.
How do you launch your online store and attract your first customers?
A successful launch starts with complete technical acceptance testing: a test order on mobile and desktop, transactional emails verified, the payment funnel checked under real conditions, analytics tracking in place. Only then does acquisition start. A store with no traffic plan is a shop opened on a deserted street.
SEO remains the most profitable lever over time, because every product page and every blog post then works without media spend. Our clients see an average of +320% organic traffic after putting a real SEO strategy in place. SEO simply needs 3 to 6 months before producing its effects, and you should know that from day one.
- SEO: optimized product pages, categories treated as landing pages, a buying-guide blog
- Google Ads and Shopping: traffic from day one, ideal for validating the offer
- Social media: Instagram and TikTok for visual products, LinkedIn for B2B
- Email marketing: abandoned cart recovery, the most profitable sequence in e-commerce
- AI visibility: 48% of Google queries trigger an AI Overview in 2026, being cited by generative engines is becoming a channel in its own right
Our advice: put 80% of the effort into two well-managed channels rather than spreading thin everywhere. A well-executed SEO + email recovery combo almost always beats five channels run halfway.
Frequently asked questions about creating an online store
How much does it cost to create an online store?
A professional online store costs from $8,000 with an agency, for a custom WooCommerce site including design, development, payment and baseline SEO. Below that, you find SaaS platforms between $30 and $400 per month, which work for testing an offer but quickly hit a ceiling in customization and SEO. On top of the initial budget come the recurring costs: hosting, maintenance from $150 per month, payment fees around 2% and an acquisition budget. The real decision criterion is not the starting price, but the total cost over 24 months measured against the revenue generated.
How long does it take to create an online store?
Expect 8 to 14 weeks to create a professional online store with an agency, from scoping to going live. Development and design take 4 to 6 weeks, the rest is split between the catalog, payment, logistics and the legal work. A store built solo on a SaaS platform can open in a few days, but that timeline hides the genuinely long work: writing unique product descriptions, preparing photos and building acquisition. At NEXUS SYNERGY, the projects that stay on schedule are the ones whose catalog is ready before development starts.
Can you create an online store for free?
Yes, technically, but not sustainably. Some platforms offer free or trial plans that are enough to validate an idea over a few weeks. A real business, however, requires a domain name, reliable hosting, a credible design and professional payment methods, which implies a budget. Free gets paid for elsewhere: forced ads, fees on sales, an off-putting subdomain and limited SEO. For a low-cost test, an entry-level SaaS plan is more honest than a free tool. To sell seriously, investing in a site you own pays for itself within the first months.
What legal structure should you choose to sell online?
In France, micro-entrepreneur status is the simplest way to start an online store: fast setup, lightweight accounting, contributions calculated on collected revenue. It reaches its limits, though, with a revenue cap of €188,700 for selling goods and no way to deduct inventory purchases. Once volumes grow, a SASU or SARL company becomes more advantageous, because it lets you deduct real expenses and protect your personal assets. The right reflex is to validate this choice with an accountant before opening, because changing structure mid-activity remains possible but tedious.
Is WooCommerce a good choice for building your online store?
Yes, WooCommerce is an excellent choice for the majority of SMBs. The e-commerce extension for WordPress makes you the owner of your site and your data, with no forced subscription and no fees on sales. Its ecosystem covers all the common needs: payment, shipping, invoicing, multilingual setups, ERP connections. The trade-off is real: you need fast hosting and regular maintenance to keep the site quick and secure. That is precisely what we have industrialized at NEXUS SYNERGY, with WooCommerce stores delivered in 8 to 14 weeks and an average Lighthouse score above 95.
How do you attract the first customers to an online store?
The first customers almost always come from two sources: paid advertising for an immediate result, and SEO for a durable flow. Launch a Google Shopping campaign at opening to validate that the offer converts, then invest the confirmed budget into SEO for categories and product pages. In parallel, activate abandoned cart recovery by email, the lever with the best return on investment in e-commerce. Your existing network counts too: customers of a physical store, social followers, partners. A welcome offer shared with this warm audience often generates the first 50 orders.
You now know the order to follow to build a solid online store: scope, choose, build, secure, then sell. If you would like an expert look at your project, our first audit is free and we reply within 24 business hours: contact the NEXUS SYNERGY team to talk it through concretely.
