Ask "what's the best e-commerce platform?" in any group of store owners and you'll get ten different answers — each one defending the platform that person happens to use. The truth is that there is no absolute best platform; there's the best one for your stage, your volume, and your strategy.
In this guide, we compare the four most relevant paths for anyone selling online in Brazil in 2026 — Nuvemshop, Shopify, WooCommerce, and a custom-built store — using the criteria that actually matter in the long run: total cost, customization, SEO, and the most overlooked of all, lock-in.
The four criteria that decide the choice
Before the platforms, the criteria:
- Total cost: it's not just the monthly fee. Add up per-sale fees, paid apps, theme, checkout, and payment gateway. A "cheap" platform that takes a cut of every order gets expensive precisely when you grow.
- Customization: how far can you adapt layout, checkout, and business rules? Every rented platform has a ceiling — the question is whether your business will hit it.
- SEO: loading speed, URL control, structured data, integrated blog. This determines whether your store will depend on ads forever or build its own traffic.
- Lock-in: if you wanted to leave tomorrow, what would you take with you? On rented platforms, the theme, the apps, and part of your data stay behind. The bigger the store, the more expensive the move.
Nuvemshop: the Brazilian entry point
Nuvemshop dominates the entry-level segment in Brazil, and deservedly so: a simple interface, native integration with Brazilian payment and shipping providers, and affordable plans — in the Brazilian market, plans typically range from token amounts to a few hundred reais per month, in some cases with a per-sale fee depending on the plan.
Strengths: fast time to first sale, Brazilian ecosystem (Correios, Pix, marketplaces), support in Portuguese, low upfront cost.
Limitations: customization limited to what the theme and apps allow; advanced features depend on paid apps that keep adding to the monthly bill; decent SEO, but little fine-grained control over performance and structure.
Who it makes sense for: anyone validating a business, with a simple catalog and revenue up to the low tens of thousands of reais per month. As a first step, it's hard to go wrong.
Shopify: the global standard
Shopify is the most mature rented platform in the world: excellent infrastructure, a store that stays stable even under traffic spikes, and a huge ecosystem of apps and themes.
Strengths: reliability, optimized checkout, scaling without technical headaches, advanced automation and internationalization features.
Limitations: costs in US dollars — the subscription, the theme, and most apps are billed in foreign currency, which hurts a Brazilian SMB's cash flow. Depending on your payment setup, there are additional transaction fees. Deep customizations require a developer who specializes in the platform. And the lock-in is real: the theme and apps don't leave with you.
Who it makes sense for: operations with significant volume, international ambitions, or a need for specific apps in the ecosystem. For small stores selling only in Brazil, the dollar-denominated cost rarely beats the domestic options.
WooCommerce: freedom with responsibility
WooCommerce turns a WordPress site into an online store. It's open source and free — you pay for hosting, theme, plugins, and above all, the labor of whoever builds and maintains it.
Strengths: total control over code and data, no platform subscription or per-sale fees, excellent SEO (WordPress is the benchmark here), and virtually unlimited customization through plugins and custom development. And zero lock-in: the store is yours, hosted wherever you want.
Limitations: that freedom charges its price in maintenance. Updates, security, backups, and performance are your responsibility (or your contractor's). A poorly built WooCommerce store gets slow and vulnerable — and a slow store kills conversion. The "free" license hides the real cost: competent professionals to build and sustain it.
Who it makes sense for: anyone who already has a WordPress site, wants to combine content and store (a strong SEO strategy), needs specific business rules, and accepts investing in ongoing professional maintenance.
Custom-built store: the ultimate asset
The fourth path is developing the store as your own project, with modern technologies, designed exactly for your operation — from catalog to checkout.
Strengths: superior performance (pages that load in a fraction of a second, which directly impacts conversion and SEO), zero per-sale fees, zero customization ceiling, tailor-made integrations with ERP, logistics, and CRM, and full ownership: code, data, and customers are yours. It's the end of lock-in.
Limitations: higher upfront investment and development time — this isn't the path for validating an idea by next week. In the Brazilian market, custom store projects typically range from a few thousand to a few tens of thousands of reais, depending on complexity. It requires a serious technical partner, because the quality of the result depends entirely on who builds it.
Who it makes sense for: established operations that have already proven their model, are hitting the limits of a rented platform, or are paying so much in fees and apps that a custom project pays for itself within a few years — sometimes within months.

Which profile fits each option
A quick summary:
- Validating the idea, tight budget: Nuvemshop. Start simple, fail cheap, learn fast.
- Medium volume, Brazil-focused, want predictability without a technical team: Nuvemshop on a higher plan or Shopify, coldly evaluating the total cost with apps and fees.
- Strong content and SEO strategy, need for flexibility: WooCommerce with professional maintenance.
- Mature operation, fees hurting your cash flow, platform limiting growth: a custom-built store.
Notice the pattern: the natural path is to start on a rented platform and evolve into owning one. The mistake isn't starting on Nuvemshop — it's continuing to pay rent and fees when the operation already justifies owning an asset.
When to migrate from a rented platform to your own store
The signs it's time:
- The fee bill is scary. Add up subscription, apps, theme, and per-sale fees for the last 12 months. If the total approaches the cost of a custom project, you're funding the platform instead of building equity.
- You're hitting the customization ceiling. Every improvement turns into "the platform doesn't allow it" or depends on yet another paid app that breaks with the next update.
- Performance is limiting conversion. A slow store on mobile, a checkout with too many steps, and no control to fix any of it.
- SEO has stalled. You want to compete organically, but you don't control the store's structure, speed, or technical data.
- Strategic dependency. Platform price increases, policy changes, and discontinued features affect your business — and you get no vote.
A well-planned migration preserves URLs (with proper redirects so you don't lose SEO), customer and order history, and happens without taking the store offline. It's a serious technical project — and it's exactly the kind of work our e-commerce service covers, from architecture selection to complete migration.
Frequently asked questions
What's the cheapest e-commerce platform?
Depends on the time horizon. In the short term, Nuvemshop and similar platforms have the lowest entry cost. In the long run, the math changes: per-sale fees and apps grow along with revenue, while a custom store has stable costs. The right question isn't "which is cheapest today?" but "which costs less over 3 years at my sales volume?".
Is it worth starting directly with a custom store?
In most cases, no — if you're still validating product and audience, the agility of a rented platform is worth more than technical perfection. The exceptions: businesses with very specific operational rules, mandatory integrations from day one, or brands launching with proven demand and premium positioning.
Does migrating platforms make the store lose its Google rankings?
If the migration is amateurish, yes — and the loss can be significant. Done correctly, with URL mapping, 301 redirects, content preservation, and post-migration monitoring, rankings hold and usually improve, because the new store tends to be faster and technically superior.
Shopify or Nuvemshop for selling in Brazil?
For an operation focused on the domestic market, Nuvemshop usually wins on the math: costs in reais and native integrations with the Brazilian ecosystem. Shopify justifies itself when there are international sales plans, a need for specific apps, or volume that demands the robustness of its global infrastructure — as long as the dollar-denominated cost fits your margin.
