Why Brazil businesses are investing in custom e-commerce platforms

Brazil is a market of about 214 million people where custom e-commerce platforms are growing fast, with Brasília as its capital.

Brazil has more than 20 million active companies, including millions of MEI micro-entrepreneurs (Mapa de Empresas). Brazil is Latin America's largest e-commerce market, and Pix has become the most used online payment method in just a few years. Portuguese UX, instalments and NF-e integration are non-negotiable.

Shoppers and trade buyers in Brazil already compare options on their phones; a custom e-commerce platform that loads fast, shows accurate stock and accepts Pix turns that research into orders.

What makes a Brazil store feel local

Conversion in Brazil depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

Everything a Brazil shopper sees — price, tax, delivery fee, refund — is in BRL, written the local way.

Language and content

Storefront copy, product pages and emails can run in Portuguese, with local date and number formats.

Local trust signals

Badges for Pix and credit cards with parcelamento (instalments), Correios delivery and clear return terms reassure first-time buyers in Brazil.

Domain, phone and contact

Using .br where it suits you signals a local business to shoppers and search engines. Contact buttons are pre-set with +55, so a customer in Brazil taps once to call or message.

A custom e-commerce platform built around your Brazil business

We do not hand Brazil businesses a ready-made theme: we study how you sell, then build the online platform and Android/iOS app your customers and staff actually need.

Typical clients include multi-brand groups, businesses outgrowing SaaS platforms, companies migrating legacy stores and regulated sectors. Categories that sell especially well online in Brazil — electronics, fashion, beauty and home and furniture — get catalogue structures and filters designed for them.

Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.

Core modules we build for Brazil clients

These are the building blocks of a custom e-commerce platform. We scope them with you, so you pay for what your Brazil operation needs.

Custom workflows

Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Reports show which products, customers and areas of Brazil drive revenue.

Headless architecture

API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Pages, search filters and wording are tuned to how people in Brazil look for products, in Portuguese if your audience needs it.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Product data imports from your existing sheets or ERP, so Brazil teams do not re-type thousands of items.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Payment steps are built around Pix, credit cards with parcelamento (instalments) and boleto bancário, the options shoppers here already trust.

Migration

Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Shipping rules can use Correios, Jadlog and Total Express as well as your own delivery staff in Brazil.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Inventory can sit in Brazil, in a partner warehouse or across Brazil, with click-and-collect where customers want it.

Who we build for in Brazil

Popular online categories in Brazil include electronics, fashion, beauty, home and furniture, health and pharmacy and pet products. In Brazil, we most often build custom e-commerce platforms for:

Enterprises with complex catalogues

Catalogue, pricing and fulfilment rules designed for enterprises with complex catalogues in Brazil, connected to the systems you already use.

Multi-brand groups

Multi-brand groups get headless architecture plus deep integrations workflows tailored to their operations.

Businesses outgrowing SaaS platforms

We map how businesses outgrowing SaaS platforms sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Companies migrating legacy stores

For companies migrating legacy stores, we usually start with migration, then add POS and store systems once orders are flowing.

Regulated sectors

Catalogue, pricing and fulfilment rules designed for regulated sectors in Brazil, connected to the systems you already use.

High-traffic retailers

High-traffic retailers get performance and security plus headless architecture workflows tailored to their operations.

Getting paid online in Brazil

Checkout is where most online sales are won or lost. In Brazil, customers expect to pay with Pix, credit cards with parcelamento (instalments) and boleto bancário, and many also look for Mercado Pago, PicPay and Apple Pay.

Provider approval, settlement time and fees differ by business type, so we shortlist gateways with you, then wire up status updates, refunds and reconciliation in BRL — card details stay with the provider.

  • Apple Pay
  • PicPay
  • Mercado Pago
  • Credit cards with parcelamento (instalments)
  • Boleto bancário
  • Pix

Delivery and fulfilment across Brazil

Your custom e-commerce platform can book shipments and share tracking with Correios, Jadlog, Total Express, Loggi, Mercado Envios and Azul Cargo, or route orders to your own riders and stores.

Delivery rules can price by distance, weight, postcode or zone, offer same-day slots in dense areas, and switch on pickup points or click-and-collect where customers prefer them.

Brazil sellers: marketplace plus your own store

Mercado Livre, Amazon.com.br and Magazine Luiza are where many shoppers in Brazil start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.

NNT Mart gives you a channel you own: your domain, your customer list, your pricing and your brand. Where it helps, we connect product feeds and orders from marketplaces so stock stays in sync and your team works from one dashboard.

Tax, invoicing and compliance in Brazil

For Brazil sellers, tax first: Brazil levies ICMS (state), IPI, PIS and COFINS on goods, with the 2023 tax reform phasing in the dual VAT (CBS and IBS) from 2026 to 2033; NF-e electronic invoices are mandatory.

Customer data is handled with the Lei Geral de Proteção de Dados (LGPD), enforced by the ANPD in mind, and the storefront follows the Código de Defesa do Consumidor (CDC) and the e-commerce decree 7.962/2013, including a 7-day right of withdrawal.

Controls we implement include compliant invoices, consent capture, policy pages, restricted staff access and audit trails. Please confirm the final legal and tax position with a local adviser.

Mobile commerce in Brazil

Because the platform is API-first, customer, staff and partner mobile apps can be added at any point without rebuilding the backend.

Apps are published under your own developer accounts and share the same backend as your custom e-commerce platform, so offers, stock and orders are always consistent between web and mobile.

Order alerts, offers and abandoned-cart reminders go out on Brazil time (UTC−3), in Portuguese if you want.

  • Cloud platforms (AWS, Azure, GCP)
  • SAP, Oracle, Microsoft Dynamics and Odoo ERPs
  • POS and store systems
  • WMS and 3PL systems
  • PIM and DAM
  • Identity and SSO
  • BI and data warehouses
  • Search engines (Elasticsearch, Algolia)

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

Launch roadmap and success metrics

We launch the journeys that create value first, then add depth. A typical roadmap for a custom e-commerce platform in Brazil:

PhaseWhat goes live
FoundationArchitecture, core commerce, priority integrations and migration. Configured for BRL, Pix and Correios from the start.
DifferentiateCustom workflows, configurators and automation.
OptimisePerformance, new channels, apps and continuous enhancement. Reviewed against how Brazil customers actually buy.

We track page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership on a live dashboard from day one, so Brazil results are visible, not promised.

Time zones, language and support

Brazil runs on UTC−3, which is 8h 30m behind India (IST). With three 8-hour shifts we are available 24×7, so meetings, demos and urgent fixes happen in your working hours.

We work in English and can deliver storefront content in Portuguese. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your custom e-commerce platform.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; clients in Brazil are served remotely with on-site workshops when the project needs them.

You approve the working result before you pay

Milestones are customised to your requirements — six or more is typical, and delivery time is agreed around your scope. Every payment after the advance is released only after you have seen the working result and given written sign-off. Here is an example plan for a custom e-commerce platform:

After go-live: warranty, support and a team that stays

Every project includes a free 90-day defect warranty. After that, the same team that built your custom e-commerce platform keeps it secure, updated and running on a fixed annual fee agreed up front — no open-ended hourly billing and no surprise invoices.

100% of the source code and IP is owned by you

For every custom e-commerce platform, upon full and final payment the complete source code and intellectual property are transferred to you — so you can host, maintain and enhance the system with any developer.

Is the platform compliant with local tax and privacy law in Brazil?

We build the technical controls — tax-inclusive pricing, compliant invoices and consent management — with the Lei Geral de Proteção de Dados (LGPD) in mind. Final legal and tax positions should be confirmed with your adviser.

Yes. After full and final payment, 100% of the source code, design files, database schemas, deployment scripts and documentation are transferred to you, with no lock-in or forced subscription.

Yes. Your own custom e-commerce platform can sit alongside Mercado Livre, Amazon.com.br and Magazine Luiza; where APIs allow, we sync products, stock and orders so your team manages everything from one admin.

How much does a custom e-commerce platform cost in Brazil?

There is no fixed package price: every NNT Mart custom e-commerce platform is quoted to your requirements and budget after a free requirements meeting and demo.
