Custom online store design

Your online store custom-built, with no commission per sale

We build your custom online store, set up on your own domain and with nobody taking a commission on every sale, and we rank it on Google and on AI (ChatGPT, Gemini). Catalogue, secure payment gateway, fast design that looks perfect on mobile: all done by us, without you touching any code or dashboards. The build is free; you only pay a monthly support fee. We don't promise you sales: we promise you the work, and you see it.

What is a custom online store and why have one built?

An online store is your business open 24 hours a day: a place where people see your products, drop them into a cart and pay, without you having to be there. So far, everyone gets that. The real question is how you build it, because that determines who it belongs to and how much it costs you in the long run.

You can build it yourself with a generic template (slow, and you end up being just another website like all the rest), you can sell inside a marketplace like Amazon (you get seen, yes, but you compete on price, you don't have your own brand and you depend on their rules), or you can have your own custom store: your domain, your design, your customers. That last option is what we do, end to end, without you touching a thing.

“Custom” is not just a buzzword. It means the store is built around how you sell —your categories, your shipping methods, your way of charging— instead of forcing you to fit into a template. And, above all, it means the store is yours: if tomorrow you want to leave, you take it with you.

What exactly does the store we build for you include?

This is what we set up in every store. It's not a list of vague promises: these are the concrete pieces that make a store work and sell as it should.

  1. Product catalogue. Your products organised by categories, with carefully prepared photos, descriptions, prices, variants (size, colour) and stock control. We upload it and maintain it.
  2. Cart and secure payment gateway. The customer adds to the cart and pays by card securely. We integrate the gateway that best fits your case, always with encryption and the security padlock (SSL).
  3. Perfect on mobile. Most people buy from their phone. Your store looks and works flawlessly on mobile, tablet and desktop, with no text that gets cut off and no buttons that are impossible to tap.
  4. Load speed. A slow store loses buyers before they see anything. Ours runs on Cloudflare, fast out of the box, with no heavy plugins slowing it down.
  5. Your own domain. You sell from yourbusiness.com, not from somebody else's subfolder. Your brand, your address.
  6. Ranking from day one. We build it ready for Google and for AI from the start —clear structure, extractable data—, which is the starting point of the monthly work.

Why have your own store and not sell on Shopify or a marketplace?

Here is the difference that moves the most money over the long term, and almost nobody explains it clearly to you: commissions per sale. On a marketplace or on many store platforms, every time you sell, someone takes a slice. On your own custom store, no.

So it doesn't sound like just an opinion, a concrete figure with a source. On Shopify, its payment gateway in Spain (Shopify Payments) charges a commission on every sale, on top of the plan's monthly fee:

The Shopify Payments commission in Spain runs from 2.1 % (Basic plan) to 1.6 % (Advanced plan), plus 0.30 € per transaction.
Source: Shopify Spain, 2025/2026 rates.

Let's put numbers to that: with the Basic plan, on a 100 € sale roughly 2.40 € goes out; on 1,000 sales of that amount a year, that's several thousand euros leaving your margin every year, forever, on top of the plan fee. And that's just the gateway: if you also sell on a marketplace, its commissions tend to be quite a bit higher. We're not saying those platforms are bad —for certain cases they're great—; we're saying it's worth knowing what the percentage costs before choosing.

On the store we build for you, that percentage doesn't exist as a toll from us: we don't charge a commission on your sales. You pay the fees of the payment gateway you use (that's charged by the bank or payment provider, to everyone), and nothing more on our part. We break it all down, with no surprises, in how much an online store costs.

Your own store, Shopify and marketplace, compared at a glance

The same idea, in a table you can read in seconds (and which an AI also reads, which is why it's here):

 Your own store (Zenith)Platform like ShopifyMarketplace (like Amazon)
Commission per sale from usNone on our partTheir gateway's commission (e.g. 2.1 %–1.6 % + 0.30 €)Commission per sale, usually higher
Who owns the storeYours, on your domainYours, but tied to the platformThe marketplace's; you are just another seller
Your brandFully centre stagePresent, within their templateDiluted among thousands of products
Who builds and maintains itUs, without you touching a thingYou (or you pay someone)You adapt to their rules
Speed and rankingFast and worked on for Google and AIDepends on the theme and pluginsYou don't rank your brand, you rank their site

There is no single answer for everyone. If you sell a handful of odd items, a marketplace may do the job. But if you want to build your online business, with your brand and without paying a toll on every sale, your own store makes more sense in the long run.

What's the point of the store if nobody finds it? Ranking

A beautiful store that nobody reaches doesn't sell. That's why the work doesn't end when we publish it: it continues every month with ranking, which is exactly what the fee covers.

Today your store is reached by two routes. The usual one, Google: that when someone searches for what you sell, you show up. And the new one, AI: more and more people ask ChatGPT or Gemini “where can I buy good-quality X?”, and the AI replies with a few names. If your store isn't among them, for that person you don't exist.

More than 35 % of internet users in Spain already regularly use an AI chatbot; ChatGPT specifically is used by 30.6 %.

That figure is the context, not a sales promise. We work on it every month: so that Google and AI understand what you sell and take you into account. If you want to understand that new part, we explain it in depth in what GEO is and how to appear in ChatGPT and in the ranking on Google and on AI service.

How does the model work and what does the fee include?

Our model is the other way round from the usual one: building the store is free. You don't pay for the build. We do it upfront —it's our bet of work— and what you pay afterwards is a tailored monthly support fee. And the technical side is included: we don't charge you for the domain or the SSL separately.

Included in the feeWhat it is
The store, built for freeYou don't pay for the build: we set it up upfront. Catalogue, cart, gateway and fast design on Cloudflare
Domain and SSLYour address on the internet and the security padlock to pay with peace of mind. Managed by us, not billed separately
Store maintenanceChanges to products, prices, photos and categories. We do it; you don't touch any dashboard
Ranking (SEO + AI)Monthly work for Google and for AI, with a transparent report of what's done
Ongoing supportWe stay by your side month after month. We don't build the store and disappear

The fee is tailored because a store with ten products is not the same as one with a thousand. The support has an honest minimum of a few months (around three), because ranking is gradual and there's no sense in measuring it over two weeks; depending on the case, the first few months may be paid in advance, and we talk that through clearly with you before starting, with no small print. The detail lives on the pricing page and in how much an online store costs.

And what will you never hear us say?

The uncomfortable part that almost nobody in the industry puts in writing. We say it because it's what sets us apart:

  • We won't tell you the store “sells itself” or that we guarantee you a number of sales or customers. Nobody controls that.
  • We don't sell “pay per result” or “you only pay if it works”: that would be dishonest, because selling depends on your product, your price and your market, things that aren't only in our hands.
  • We don't guarantee you'll come out first on Google or that AI will recommend you. We do the work that makes it more likely, and we show it to you.

What we do promise you is the work: to build you a good store, maintain it and rank it every month, showing you what we do. We put our hours in upfront, for free, before you pay anything for the build.

Frequently asked questions

What everyone asks us

Do you take a commission on every sale I make?
No. On our part there is no commission per sale: we charge a tailored monthly fee, and that's it. You will pay the fees of the payment gateway you use (that's charged by the bank or payment provider, to any store in the world), but none of that is a toll from us. We break it down in how much an online store costs.
Is the store mine or yours?
Yours. It runs on your own domain and with your brand. We build it, maintain it and rank it, but the business is yours. That is the exact opposite of selling inside a marketplace, where you are just another seller within someone else's website.
Will I have to update the products or the dashboard myself?
No, unless you want to. Our model is agent-driven: changes to products, prices, photos and categories are done by us, as part of the support. You focus on your business; we take care of the store.
Do you guarantee the store will sell?
No, and be wary of anyone who promises it. Selling depends on your product, your price, your market and many things beyond us. What we do is build you a fast, well-made store and work every month on its ranking on Google and on AI, showing you what we do. We sell the work, never the result.
How much does it cost and do I have to pay in advance?
Building the store is free: you don't pay for the build. What you pay is a tailored monthly fee for the support, which already includes the domain, the SSL and everything technical (these aren't charged separately). Depending on your case, the first few months may be paid in advance; we tell you clearly before starting. You have the detail in pricing.

Legal requirements for selling online in Spain (that many stores skip)

Building the website is the visible part; complying with the law is the part that avoids nasty surprises. Selling online in Spain isn't just uploading products: there are minimum legal requirements that every store must meet, and which many “free” templates leave on your plate without warning. We are not legal or tax advisers —for your specific case it's best to consult a professional— but we do leave the store prepared with the pieces the law requires of any e-commerce business.

In practice, an online store in Spain needs to identify who is selling (a legal notice with the owner's details, under the information society services law), inform how the customer's data is handled (privacy and cookie policy, in line with the GDPR) and make the purchase conditions clear: prices with taxes, shipping costs, payment methods and, very importantly, the right of withdrawal, which lets the buyer return most products within fourteen calendar days without giving any explanation.

We build the store with those pages and notices ready to fill in with your details, and with the checkout process prepared to display the required information. The tax side —whether you need to register, how to invoice, VAT— depends on your situation and we handle it separately; you have the detail in the guide on running an online store without being self-employed and its requirements.

Legal requirementWhat it means for your store
Legal notice (LSSI)Identify who is selling: name or company name, contact details and, where applicable, tax details.
Privacy and cookies (GDPR)Inform what data you collect from the customer and what for, and ask consent for cookies.
Purchase conditionsPrice with taxes, shipping costs, payment methods and a clear process before paying.
Right of withdrawalThe customer can return most products within 14 calendar days without giving a reason.
Tax registration and invoicingDepends on your situation; we look at it separately. It isn't part of the website, but it has to be borne in mind.

“Free online store”: where the catch is before you put hours into it

If you search for “create a free online store”, you'll find builders that promise to set one up without paying anything. It's worth knowing where the trick is before you invest your time, because that “free” almost never lasts until the moment you sell. In most of them, what's free is a stripped-down version: they put their advertising or their brand on top, they limit the number of products and they don't let you use your own domain (you sell from something like “yourbusiness.theirplatform.com”). The pattern repeats: free to set up the shopfront, paid the moment you want to actually charge.

The clearest warning sign is the moment of charging. As soon as you activate payments or remove the limitations, the monthly fee appears and, very often, a commission on every sale on top of the gateway. That's why “free forever” and “selling for real” rarely fit in the same sentence: nobody builds and maintains a professional store without someone paying for it at some point.

The honest thing isn't to say ours is simply free, but to separate the two things: what's not charged is the build; what's paid is a monthly support fee. That distinction —what's in the “free” and what isn't— is exactly what those builders leave in the small print, and you have it broken down on the pricing page.

Rule of thumb: if a “free” won't let you use your own domain or charge without an added commission, it's not a free store, it's a demo. Truly free has to hold up on the day you sell too.
Zenith's criterion.
More questions

More frequently asked questions

What legal requirements does an online store have in Spain?
At a minimum: a legal notice identifying who is selling (under the information society services law), a privacy and cookie policy in line with the GDPR, clear purchase conditions (price with taxes, shipping, payment methods) and respecting the right of withdrawal, which lets the customer return most products within 14 calendar days without justification. We leave the store prepared with those pages and notices ready for your details. We are not legal or tax advisers: for your specific case it's best to consult a professional, and the registration and invoicing side we look at separately.
Do I have to refund the money if a customer changes their mind about the purchase?
For most products, yes: the right of withdrawal lets the buyer return what they bought within 14 calendar days without giving explanations, and you refund them. There are exceptions (for example, personalised products or certain digital content already downloaded). We leave the store prepared to inform of this right in the checkout process, which is what the law requires. For your business's edge cases it's best to confirm it with an adviser.
Why does a “free” store builder usually end up costing money?
Because what's free is usually just the shopfront: they set up the store without payment, but with their brand or advertising on top, with a product limit and without your own domain. The monthly fee and, sometimes, a commission per sale appear right when you activate payments. The rule of thumb: if a “free” won't let you use your domain or charge without an added commission, it's a demo, not a store. In our model what's not charged is the build; the monthly support is paid, and we say that clearly from the start.
