What To Check First

Vetting a e-commerce mobile app developer in São Paulo

Here's how to tell a real e-commerce specialist apart from a generalist agency that only adds your sector to its homepage once you're signed.

Published live stores with page speed scores above 80 on GTmetrix-ask for the report before signing

Checkout A/B testing experience: agencies that have run live split tests understand what moves conversion rates beyond gut instinct

Local payment method integrations: Stripe, PayPal, and any market-specific gateways active in São Paulo

SEO-ready product architecture: canonical URLs, structured data for products (Schema.org/Product), faceted navigation without crawl debt

Post-launch support with defined SLA-e-commerce sites fail during peak traffic, usually when you least want to be calling a developer

Platform Choices

Which platform suits e-commerce apps in São Paulo?

Shopify / Shopify Plus

Best for speed to market. Custom theme development on Shopify 2.0 gives full design control without leaving the hosted platform. Shopify Plus is the correct choice above £500,000 annual GMV.

WooCommerce

Best when the client already runs WordPress or needs customisation beyond Shopify's API surface: subscription logic, complex tax rules, multi-currency with local rounding.

Headless (Next.js + Shopify Storefront API)

Recommended for stores exceeding 10,000 monthly transactions or brands that require sub-1-second product pages. Higher build cost; dramatically better Core Web Vitals scores.

Magento 2 / Adobe Commerce

Enterprise choice for multi-store, multi-language, multi-currency setups. Requires a dedicated Magento-certified developer-not all São Paulo agencies have this.

Common Questions

E-commerce mobile app questions from São Paulo businesses

What e-commerce companies in São Paulo tend to ask before greenlighting an app project.

Which e-commerce platform do web developers in São Paulo recommend?+

Shopify is the default recommendation for most São Paulo businesses launching a new store-faster to build, easier to operate, and lower ongoing maintenance. WooCommerce is the right choice when the client already runs WordPress or needs more complex customisation. Headless commerce (Next.js + Shopify API) suits stores exceeding £1M GMV where load speed and UX directly impact revenue.

How much does an e-commerce website cost in São Paulo?+

A Shopify store with brand-customised theme costs £1,500–£5,000 in São Paulo. A custom WooCommerce build with product filtering and payment gateway integration runs £5,000–£18,000. Enterprise headless commerce starts at £25,000. Ongoing costs include hosting (£20–£200/month), platform fees (Shopify £29–£299/month), and maintenance retainers.

How long does e-commerce development take?+

A Shopify store with a customised premium theme takes 1–3 weeks. A custom WooCommerce build is 4–8 weeks from brief to launch. A headless commerce platform with custom checkout flows and ERP integrations is 12–24 weeks. Timelines extend when product data, photography, or payment gateway approvals are delayed.

Do I need a specialist e-commerce agency in São Paulo or will any web developer do?+

E-commerce development requires specific expertise that general web developers often lack: checkout conversion optimisation, inventory management integration, tax and shipping logic, and PageSpeed compliance affecting Google Shopping rankings. Ask any candidate agency to show you 3 live stores and their current Core Web Vitals scores in Google Search Console.

What should a São Paulo business look for in a contract before hiring a web developer?+

A properly scoped web development contract for a São Paulo business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the São Paulo web development market.

How long does a São Paulo web project typically take from brief to launch?+

A standard business website for a São Paulo company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in São Paulo web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.

Should a São Paulo business hire a local web developer or work with a remote agency?+

For most São Paulo businesses, a remote web development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for web development quality since 2018. Tkist Digital serves clients across Brazil and 40+ countries entirely remotely.

How can a São Paulo business verify a web developer's experience before signing?+

The three most reliable verification methods for São Paulo businesses evaluating web developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist Digital provides live portfolio URLs, verified client references, and a free technical scoping call for every São Paulo project enquiry.
