Standard platforms work until you need complex business rules. My work begins where Shopify falls short: integrating your ERP bidirectionally and ensuring your multichannel inventory balances perfectly, even during Black Friday.

Ecommerce design and development

Connect sales with business operations

When the catalog, prices or order management have their own rules, it is necessary to assess how to resolve them without complicating day-to-day operations. Let's compare the possibilities of a standard platform with custom development.

We develop custom ecommerce, both B2B and online stores with the functionalities and integrations that each company needs. We design the purchase journey and define how it connects with stock, payments and management.

From the operation to the store

We define e-commerce based on purchasing processes and needs.

  • Understanding the sale

    We review the catalog, customers, commercial conditions and channels, and analyze the particularities of your sector, to define what the store needs.

  • Design the purchase

    Ecommerce design focused on the shopping experience: search, navigation, listings and payment. We check usability on mobile and desktop and define what to measure to improve conversion (CRO).

  • Define integrations

    We define the integration with the ERP you already use and with the CRM, the multichannel stock and the data that is synchronized. We agree on the update frequency and how to detect and resolve errors.

  • Load the catalog

    We prepare the bulk ingestion of the product catalog, so loading and updating thousands of products doesn't depend on manual work.

  • Build in phases

    We share functional progress to check journeys and adjust decisions within the agreed scope.

  • Connecting payments and logistics

    We choose payment gateways and logistics connections based on the business and available suppliers. We test flows before launch.

  • Prepare for launch

    We test the expected load and critical paths. We agree on monitoring and support after launch.

  • Monitor the store

    After launch, application security and monitoring are paramount: we protect your customers' data and their payments, and alerts flag an incident before anyone notices it.

Experience beyond the storefront

From the catalog to the order

We have been building e-commerce since 2012, experience that goes back to the early days of Anxaneta. We know the usual pitfalls: customer-specific pricing and terms, real-time stock and recurring orders.

That's why we know how to model the data and which infrastructure to run it on: thousands of SKUs, customer prices and stock are queried in milliseconds, even as the catalog grows. It's a foundation built to grow with your company.

After launch, we measure where the purchase is abandoned to decide which improvements to prioritize.

Frequently Asked Questions

Answers to the most common questions about custom e-commerce design and development.

Everything You Need to Know Before You Start

When commercial rules, the catalogue or integrations do not fit a standard platform well. Before building a custom solution, we compare what configuration can resolve and what needs dedicated development. Expected volume is assessed through tests, not just the technology chosen.

No. We have Carticious, our own e-commerce foundation already built, and platforms in production such as Nou Grup's, where 14 companies each sell through their own store on the same base. We start from what already works and adapt it to your catalog, your commercial conditions and your integrations.

Custom ecommerce development starts at €25,000 for projects with basic functionalities and a personalized ecommerce design. Stores with ERP/CRM integration, advanced conversion rate optimization (CRO) features, and multichannel inventory management typically range from €40,000 to €100,000. We'll give you a fixed price for the scope we agree on after analyzing your needs.

We choose options based on buyers, markets and suppliers. We assess costs, conditions and integration before confirming which ones are incorporated.

We review where inventory is maintained and which connections each channel offers. We define the data, update frequency and error handling before confirming scope. Immediate synchronisation depends on the capabilities of the systems involved.

We agree expected load and test critical journeys before a campaign. Based on the results, we plan the capacity and monitoring needed. Performance depends on the application, integrations and infrastructure working together.

Yes. We design and test the shopping experience on mobile and desktop. We review navigation, product pages, forms and checkout before launch.

Yes. Custom e-commerce requires continuous improvement: conversion rate optimization (CRO) through A/B testing, security updates, new features, metrics analysis, and adjustments based on user behavior. We offer maintenance contracts with different levels of support.

Before confirming a migration, we review which data can be exported, its quality and the existing URLs. We define what to transfer, test the import and plan redirects and incident recovery. Search positions cannot be guaranteed to remain unchanged.
