Retail, ecommerce and professional services. Catalogues machines can read and people can buy from.

Polargate rebuilds online shops and catalogues as static HTML that search engines and AI assistants can read, with your products and prices in your own database.

The problem

What we hear on the first call.

If any of these sounds familiar, that is where we start.

  1. 01

    We redesigned the shop last year and sales did not move. Nobody can tell me why.

  2. 02

    Customers ask ChatGPT what to buy and it names three competitors, never us.

  3. 03

    The catalogue lives in three places: the shop, the feed, and a spreadsheet the warehouse keeps.

  4. 04

    Some orders cost us more in shipping than we charged, and we only find out at the end of the month.

  5. 05

    Every price or stock change goes through the agency and takes two weeks.

  6. 06

    Merchant Center keeps rejecting items and nobody here can read the errors.

  7. 07

    The photos look right in the studio and take forever to load on a phone.

For example: 105,212 characters of body text readable by AI crawlers across 65 URLs, up from zero. Malacca Tables

Projects · Retail, ecommerce and professional services

What we build.

Each piece connects to the systems you already use, and everything stays in accounts your company owns.

A phone in the stockroom of a home décor shop: today's orders to prepare, one armchair ready for collection and a button to let the customer know, while a parcel goes out the door.
  • 01

    A storefront on infrastructure you own: catalogue, series, variants, cart, checkout, customer accounts and orders, with your repository and your own Supabase and Vercel projects.

  • 02

    Category, series and product pages pregenerated as real HTML, each with its own metadata and JSON-LD, protected by build guards so a page can never quietly go empty.

  • 03

    Product feeds regenerated on every build for Google Merchant Center, Meta and Pinterest, plus sitemap, robots policy for search and answer crawlers, and Search Console setup.

  • 04

    Shipping and pricing rules in the database, so the estimate a customer sees and the amount charged on the order come from the same calculation.

  • 05

    Card payments through your own bank virtual terminal or gateway, with the amount re-read server-side, the signature verified and repeat notifications made idempotent.

  • 06

    An admin panel for your team: orders, products, prices, stock, series, shipping and role-based invitations, instead of a plugin ecosystem you then maintain.

  • 07

    Migration off WooCommerce, Shopify or a legacy CMS, verified item by item, followed by a CARE retainer with ServiceDesk and a written monthly report.

What changes in this sector

Two things changed at the same time. People now ask an assistant before they open a shop, and most shops are invisible to it. GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot fetch raw HTML and do not run JavaScript. When we rebuilt the store of a premium tableware and home linen brand in Madrid in 2026, we put the full catalogue in the HTML of all 65 URLs, so an assistant can read every product.

The second change is less visible. In retail the margin lives in the plumbing: carrier tariffs by weight and zone, VAT on every fee, honest reference prices, stock that matches the warehouse. None of that is a design problem. It is margin won one order at a time, by reading the rules line by line.

In B2B and professional services the same problem takes a different shape. There the catalogue is the work itself: references, articles, specifications. KD.tech, a Spanish semiconductor company, has 327 bilingual pages worth reading, and its site now scores 100 for SEO on mobile. Same approach, different content.

How it is priced

A shop with catalogue, checkout, payments and an admin panel has a fixed price that depends on catalogue size and integrations, payable in monthly instalments. A catalogue or reference site without checkout is a smaller build. Both begin with a Discovery Sprint that closes scope and price. After launch, a CARE retainer covers maintenance, evolution and the ServiceDesk, and search and AI visibility work runs inside the same contract. Tell us about your catalogue and you get a private quote.

How we work

From brief to production.

Every project starts with a paid Discovery Sprint that closes scope and price, and every change goes through the same loop of building, auditing and fixing until two passes come back clean.

01The four phases

  1. 01

    Discover

    Two paid weeks that end in a closed scope, an architecture and a fixed price.

  2. 02

    Build

    Senior engineers with AI, a review on every change and a production release in weeks.

  3. 03

    Grow

    Search, AI assistants and paid media, measured from the first week.

  4. 04

    Care

    Monthly maintenance with a first answer within 48 business hours.

For example: 4 days from diagnosis to the new backend running. Concert Music Festival

FAQ

What people ask us.

How much does a custom online shop cost?
A shop with catalogue, checkout, payments and an admin panel has a fixed price that depends on how many products, variants and integrations are in scope. It can be paid in monthly instalments. Before that, a Discovery Sprint closes scope and price. Tell us about your catalogue and you get a private quote.
Can you connect the shop to our ERP, our warehouse and our payment provider?
Yes, and we start from what you already pay for. We have integrated a Spanish bank virtual terminal over the CECA protocol, carrier tariffs by weight and zone, warehouse stock lists and product feeds for Google Merchant Center, Meta and Pinterest. Where a system has no usable API we work with what it does expose: one catalogue was migrated entirely through a public Store API, without admin access to the old shop.
Why do ChatGPT and Perplexity never mention our products?
Usually because they cannot read your catalogue. Those crawlers fetch raw HTML and do not run JavaScript, so a shop that paints its products in the browser looks empty to them. It takes one command to check. On one rebuild, all 65 URLs returned zero characters of text before the work and 105,212 characters after it, refreshed daily so the pages follow stock and prices.
Do we have to leave Shopify or WooCommerce?
Not always. If the platform is doing its job, Polargate fixes what is broken inside it: rendering for crawlers, feeds, structured data, page speed, shipping rules and checkout. We rebuild when the platform is the problem, for example when nobody can get into the admin any more, or when plugin fees and workarounds cost more than owning the code. Migration is verified item by item, not trusted to an importer.
Who looks after the shop after launch?
Polargate does, on a monthly CARE retainer. That covers senior maintenance, releases, dependency and security updates, incident handling through a multi-tenant ServiceDesk and a monthly written report. The person who answers your ticket is the person who wrote the code. We do not promise round the clock cover, and we say so before you sign rather than after.
