Why a custom e-commerce platform makes sense for Madrid
Madrid is a capital and largest city of spain, home to about 3.5 million people, and one of the markets in Spain where we build custom e-commerce platforms.
Key sectors include banking, corporate HQs, telecom and startups, with business districts such as Paseo de la Castellana, AZCA and Las Tablas.
Logistics are supported by Adolfo Suárez Madrid-Barajas Airport, which matters when you promise customers fast delivery.
Spain has about 3 million companies, over 99% of them SMEs (Ministry of Industry). Spain's online shoppers are highly mobile and increasingly pay with Bizum. Regional language options and reliable delivery to the islands help brands stand out.
That is why more companies in Madrid are moving from phone, WhatsApp and spreadsheet orders to a proper custom e-commerce platform — one place where products, prices, payments, orders and customers are managed together.
Local details we build into every Madrid project
A store that works in Madrid respects local habits as well as local law. These are the details we configure first.
Currency and pricing
Prices, taxes, shipping and refunds are shown in euro (EUR), formatted the way Madrid customers read them.
Language and content
Content can be produced in Spanish, Catalan and Basque, so a Madrid customer reads the store in the language they use at home.
Local trust signals
Badges for Visa and Mastercard and Bizum, Correos delivery and clear return terms reassure first-time buyers in Madrid.
Domain, phone and contact
Using .es where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +34 calling code so customers reach you without dialling errors.
Talent and partners nearby
Madrid draws on Complutense, Polytechnic University of Madrid and IE University, which means plenty of local staff, interns and technology partners to run the store after launch.
Designed to your requirements, not a template
Your custom e-commerce platform is planned, designed and coded for your business model — not adapted from someone else's — and it can ship with a customer or staff mobile app on day one.
In Madrid we typically work with enterprises with complex catalogues, multi-brand groups, businesses outgrowing SaaS platforms and companies migrating legacy stores, and with sellers in categories such as fashion, electronics, travel and leisure and beauty that have strong online demand in Spain.
We start with a requirements meeting, show you a working demo within 24 hours, and only then propose scope, milestones and budget.
Core modules we build for Madrid clients
These are the building blocks of a custom e-commerce platform. We scope them with you, so you pay for what your Madrid operation needs.
Custom workflows
Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Reports show which products, customers and areas of Madrid drive revenue.
Headless architecture
API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Storefront language, imagery and navigation are set up for Madrid shoppers and available in Spanish and Catalan.
Multi-entity operations
Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Catalogues come in from spreadsheets, ERP exports or supplier feeds, so your Madrid team keeps its current way of working.
Deep integrations
ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Checkout is configured for Visa and Mastercard, Bizum and PayPal.
Migration
Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Couriers such as Correos, SEUR and MRW plug in alongside your own fleet for Madrid orders.
Performance and security
Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Multiple stock points in Spain are supported, so a Madrid order ships from the nearest one.
Businesses that use NNT Mart in Madrid
Popular online categories in Spain include fashion, electronics, travel and leisure, beauty, home and food and gourmet. Local demand in Madrid is shaped by banking, corporate HQs, telecom and startups, so we often design catalogues and B2B ordering around those sectors. In Madrid, we most often build custom e-commerce platforms for:
Enterprises with complex catalogues
Enterprises with complex catalogues get custom workflows plus multi-entity operations workflows tailored to their operations.
Multi-brand groups
We map how multi-brand groups sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Businesses outgrowing SaaS platforms
For businesses outgrowing SaaS platforms, we usually start with deep integrations, then add WMS and 3PL systems once orders are flowing.
Companies migrating legacy stores
Catalogue, pricing and fulfilment rules designed for companies migrating legacy stores in Madrid, connected to the systems you already use.
Regulated sectors
Regulated sectors get migration plus custom workflows workflows tailored to their operations.
High-traffic retailers
We map how high-traffic retailers sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Checkout and payment methods for Madrid
A store that serves Madrid should let customers pay the way they do offline: Visa and Mastercard, Bizum, PayPal and Apple Pay.
Gateway selection depends on your category and merchant approval; we connect the provider, reconcile payments, automate retries and refunds, and never store raw card data. Prices, taxes and refunds appear in euro (EUR).
Zone-based payment rules let you offer different options for Paseo de la Castellana than for outer parts of Madrid.
- Apple Pay
- Bizum
- Klarna and Aplazame instalments
- Visa and Mastercard
- Cash on delivery (contra reembolso)
- PayPal
Fulfilment options for Madrid orders
Your custom e-commerce platform can book shipments and share tracking with Correos, SEUR, MRW, GLS Spain, Nacex and CTT Express, or route orders to your own riders and stores across Madrid.
We set up shipping zones, cut-off times, free-shipping thresholds, cash-collection rules and returns so the promise on the product page matches what your team can deliver.
Connectivity in the area — Adolfo Suárez Madrid-Barajas Airport — makes regional and national dispatch from Madrid practical.
Your own store alongside Amazon.es and El Corte Inglés
Many Madrid sellers already list on Amazon.es, El Corte Inglés, AliExpress, PcComponentes, Wallapop and Carrefour. Those channels bring traffic, but they also take commission, control the customer relationship and change rules without notice.
With your own custom e-commerce platform you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.
Compliance built into your custom e-commerce platform
For Madrid sellers, tax first: Spanish IVA is 21% standard with 10% and 4% reduced rates; the Canary Islands use IGIC instead of IVA.
Two frameworks shape the build: the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent, plus the LOPDGDD and LSSI-CE, enforced by the AEPD, and the EU Consumer Rights Directive (14-day withdrawal right), the Digital Services Act and, from June 2025, the European Accessibility Act for online shops and the General Law for the Defence of Consumers and Users.
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 in Madrid.
Mobile commerce in Madrid
In Madrid, shoppers browse on phones first. 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.
Push notifications can be timed to UTC+2 so offers reach Madrid customers when they are awake, and the interface can run in Spanish and Catalan.
- Search engines (Elasticsearch, Algolia)
- PIM and DAM
- WMS and 3PL systems
- Cloud platforms (AWS, Azure, GCP)
- BI and data warehouses
- SAP, Oracle, Microsoft Dynamics and Odoo ERPs
- POS and store systems
- Identity and SSO
Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.
From first demo to growth in Madrid
Value first, depth later. For a custom e-commerce platform serving Madrid, the usual sequence looks like this:
| Phase | What goes live |
|---|---|
| Foundation | Architecture, core commerce, priority integrations and migration. Configured for EUR, Visa and Mastercard and Correos from the start. |
| Differentiate | Custom workflows, configurators and automation. |
| Optimise | Performance, new channels, apps and continuous enhancement. Reviewed against how Madrid customers actually buy. |
Success is measured on page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership — tracked on a dashboard you can see from launch day.
Working with our team from Madrid
Our team covers UTC+2 — 3h 30m behind India (IST) — through three 8-hour shifts, so a Madrid client always reaches someone during the local working day.
Project communication is in English; storefront content can be produced in Spanish. You get a named lead, direct engineer access and an NDA if you ask.
Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; Madrid clients are served remotely with on-site workshops when the project needs them.
