Creating an online store in 2026 is more accessible than ever, but also more competitive: it’s no longer enough to upload products and wait for sales to arrive on their own. You need a clear business model, the right platform and a purchase process that turns visits into customers. This guide walks through the six steps, designed for the Argentine market.
Step 1: Define the business model before choosing a platform
Before thinking about design or technology, you need to be clear about what you’ll sell, to whom and how you’ll generate revenue. Selling your own products isn’t the same as working with third-party stock or doing dropshipping — the clearer the model, the more coherent the decisions you make afterward will be.
Before moving on, answer these questions:
- What problem does your product solve?
- Who is your ideal customer?
- What’s your profit margin per sale?
- Will you sell only in Argentina or also abroad?
Step 2: Choose the platform according to your volume and budget
The platform defines how much you’ll pay each month, how much control you’ll have and how fast you can scale. These are the most common options in 2026:
| Platform | Ideal for | Monthly cost | Commission per sale |
|---|---|---|---|
| Tiendanube | SMEs selling in Latam, first steps | From $0 (with commission) | 0.5% – 2% |
| Shopify | Brands with global ambition, multi-country | USD 39 – 399 | 0.5% – 2% |
| WooCommerce | Total control, technical teams, SEO | Hosting + plugins | 0% |
If you’re just starting out, a SaaS platform like Tiendanube takes the technical side off your plate. If you already have a development team and want total control over the code, WooCommerce gives more flexibility in exchange for more work of your own.

Step 3: Build the page structure every store needs
An online store isn’t just a product page. These are the sections that shouldn’t be missing:
- Home: communicates who you are, what you sell and guides the visitor toward your star products.
- Product pages: each with title, description, price, images, variants (size, color) and reviews if possible.
- Contact: form, email, phone and opening hours — a live chat speeds up inquiries.
- About us: builds trust by telling the story of the business and the team.
- Frequently asked questions: resolves doubts about payments, shipping and returns before they arrive as messages.
- Policies: returns, privacy, terms and conditions, and shipping policy — they don’t just build trust, they’re also legal backing.
Step 4: Design a frictionless shopping experience
Design in ecommerce isn’t just aesthetics: it’s what decides whether a visit turns into a sale. The fewer obstacles the user finds, the easier it is for them to complete the purchase — usability, loading speed and mobile adaptation are critical, not optional.
Some practical tips to get started:
- Choose a template that fits your industry and your product volume.
- Don’t obsess over colors and typefaces at first; they can be adjusted later.
- Prioritize features that reduce friction: search with autocomplete, a reviews section, product filters.
Step 5: Set up payments and shipping for the Argentine market
An ecommerce store doesn’t work if you can’t collect payment or deliver what you sell. For the Argentine market, Mercado Pago is the dominant gateway: its Checkout API lets you offer credit and debit cards, transfers and cash payments from a single screen, without redirecting the buyer away from your site. That integration — getting credentials, configuring payment methods and rendering the form in your checkout — is worth doing well, because every extra step in checkout is an opportunity for abandonment (in Checkout that converts: 7 mistakes that are costing you sales we review the most common ones).
For logistics, Mercado Envíos lets you integrate shipping with Correo Argentino directly from your Mercado Pago account: when a sale is completed, a label is generated that you print and stick on the package. Defining costs, delivery times and return policy in advance avoids friction once you start selling.
Step 6: Launch and optimize with real data
Once everything is ready, the work doesn’t end at publishing. Install Google Analytics and Search Console, set up conversion tracking and check how often carts are abandoned. An ecommerce store isn’t a static project but a system that adjusts with every batch of data — pages with a lot of traffic and little conversion are the first candidates to review.
Choosing the platform is the decision you notice on day one. The one you notice six months later is whether you built the store to sell, with a simple checkout, complete product pages and logistics that don’t leave the buyer in doubt.
With the business model defined, the platform chosen and payments and shipping sorted out, the rest is iteration: every sale (and every abandoned cart) will tell you what to adjust first.
