Ecommerce website design in Madrid for shops that sell

Custom or Shopify online shops that are fast and easy to buy from, linked to your orders, your stock and your messages so you sell more with less work.

Aventib's ecommerce website design in Madrid means building custom or Shopify online shops around your catalogue and your customers, and connecting them to the rest of your business: order alerts, automated emails, abandoned baskets, WhatsApp and stock. You sell around the clock and spend less time on repetitive tasks. We work with shops all over Spain.

Why is selling through an online shop so hard?

  • Buying is harder than it looks

    Confusing filters, product pages without information and a checkout with too many steps. Every small obstacle makes customers abandon their basket and never come back.

  • You sell by hand on Instagram or WhatsApp

    You answer price questions one by one, write orders in a notebook and confirm bank transfer payments. It works while orders are few, but becomes impossible as the business grows.

  • Orders, stock and shipping kept separate

    Your shop, your stockroom and your courier don't talk to each other. You end up copying data from one place to another and mistakes creep in: out-of-stock products still being sold or late deliveries.

  • Customers who buy once and disappear

    Without automated emails or follow-up, people who bought from you once forget about you. Winning a new customer costs more than getting a happy one to come back.

Ecommerce website design connected to the way you sell

Tell us what you need
  • A catalogue built for finding things fast

    We organise categories, filters and search around how your customers look for products, not how your stockroom is laid out. Visitors find what they want within seconds and reach the product page sooner.

  • Product pages that answer questions

    Photos, price, variants, reviews, delivery times and returns explained clearly. A good product page answers the questions people used to send you on WhatsApp and makes adding to the basket the natural next step.

  • Easy payment with familiar methods

    We set up card, PayPal, Apple Pay, Google Pay or Bizum (Spain's popular mobile payment system), depending on the platform and payment gateway you choose. A short, clear checkout reduces baskets abandoned at the last step.

  • Orders and stock that manage themselves

    Every order reaches you with an instant alert and is ready to prepare. We connect the shop to your stock, invoicing or suppliers, including dropshipping shops, so you don't have to copy data by hand.

  • Sales that repeat

    Automated welcome emails, abandoned basket recovery, back-in-stock alerts and post-purchase messages. Your customers come back without you having to remember to write to each one.

  • WhatsApp customer service with AI

    If you need it, an AI assistant answers questions about sizes, delivery or order status at any hour. Anything sensitive, such as an unusual return, comes to you to decide.

How your shop works while you sleep

An example of how it works. Every business is set up to fit.

  1. A customer isn't sure about her size

    She messages on WhatsApp from the product page. The assistant explains the size guide and reminds her that exchanges are easy.

  2. She buys in three steps

    She adds to basket, pays with Bizum and instantly receives a confirmation email with all the order details.

  3. The order is ready

    Stock is deducted automatically, the order appears in your dashboard and the shipping label is ready to print in the morning.

  4. You just check and ship

    You open the dashboard, see the night's orders neatly listed and start packing parcels, without answering messages one by one.

What you gain from Aventib's ecommerce website design in Madrid

You sell around the clock

The shop serves customers, takes payment and confirms orders even when you're not there. You stop losing sales because a message arrived late or at night.

Less manual work

Orders, stock, emails and alerts move automatically between your tools. Your time goes on preparing shipments and improving the catalogue, not on copying data.

Customers who come back

Automated emails and post-purchase follow-up encourage people who already know you to buy again. And you can measure how many sales come from each channel.

How we set up ecommerce website design for you

    We get it going

    We build the shop, upload products, set up payments and shipping and place real test orders before going live. Then we show you how to run it.

    We look at sales, abandoned baskets and the most viewed products. With that data we adjust product pages, shipping costs or the checkout wherever sales are being lost.

Frequently asked questions about ecommerce website design

How much does ecommerce website design in Madrid cost?

It depends on the project: number of products, features, integrations and whether it's built on Shopify or custom-made. We don't give fixed prices without getting to know you. First we understand your business, then we send you a clear proposal detailing what's included. Bear in mind that platforms like Shopify also charge their own monthly fee.

Which platform is best for building an online shop?

We mainly work with Shopify because it's stable, secure and easy for a small business to manage. If your project needs it, we use other solutions, such as WooCommerce within WordPress. We recommend whichever fits your catalogue, budget and way of working best, and explain why.

Will I be able to manage products and orders myself?

Yes. From a simple dashboard you can add products, change prices, view orders and keep track of stock. When we finish, we show you how to use it step by step so you feel comfortable and don't depend on anyone day to day.

Do you build dropshipping shops?

Yes. We build dropshipping shops connected to your suppliers so orders and stock are managed automatically. First we go through how each supplier works with you, because the delivery times your customers see depend on them.

I sell on Instagram and WhatsApp. Do I need an online shop?

If you answer lots of price questions by hand and lose sales by not replying in time, probably yes. With an online shop your customers buy on their own and you receive the order ready to go. You can also connect WhatsApp to the shop to keep answering questions without losing control.

Do you work with shops outside Madrid?

Yes. We're in Boadilla del Monte, Madrid, and we design online shops for businesses all over Spain. The whole project can be run by video call, WhatsApp and email, with a single point of contact who coordinates design, platform and connections.
