An e-commerce isn’t just a shop window
Opening an e-commerce often gets reduced to “making a site with some products”. That’s where the projects that don’t sell come from. An online store is logistics, payments, stock and speed put together. The nice graphics are the last thing: if checkout is slow or stock is wrong, you lose the order anyway, however polished the window.
The right way to look at it is as a piece of how you sell, not as a digital flyer. It has to talk to the stock you already have, to invoicing, to couriers. When one of these pieces limps, the cost doesn’t show in the quote: you see it in abandoned carts and orders handled by hand.
The pieces you need to sell
An e-commerce that sells has a few non-negotiable pieces. A catalogue with variants, prices and availability manageable without losing your mind. A fast, secure checkout with the payment methods your customers actually use. Shipping and stock synced with your software, so you don’t sell what you don’t have. And product pages tuned for Google and for AI search, because a product that can’t be found is a product that doesn’t sell.
Each of these pieces, done poorly, costs you sales quietly. A checkout with one step too many loses customers right at the end. A wrong stock level generates an order you then have to cancel, with the bad look that comes with it. That’s why the question isn’t “how much does the site cost”, but “which of these pieces do I need and how well must they work”.
How much opening an e-commerce costs
The cost of an e-commerce depends on three factors: how many products and variants you have to manage, how many integrations you need (software, couriers, invoicing, payments) and how much care over time. A store with few products and a standard checkout sits in the lower range. One connected to stock, with syncing and shipping rules, takes more work, and the price follows.
As with managed websites, there are two lines: the initial build and the fee that keeps the store fast, secure and updated. A store connected to stock costs more than an isolated showcase, but saves you double entry and errors, meaning time and lost orders. Our e-commerce solutions always start from here: what it has to sell, what it has to talk to, how much load it has to take.
Why speed and stock sync matter
In online commerce, speed is direct money. Every extra second of wait on checkout is a slice of customers who give up. Slow product pages drop on Google and get seen by fewer people. A fast e-commerce isn’t a technical vanity: it’s the condition for everything else to make sense.
Stock sync matters as much as speed. If the site’s stock and the shop’s don’t match, you sell what you don’t have or block what you could sell. Connecting the store to your software with a well-built integration ends double entry and keeps the numbers aligned both ways, in real time.
Ready-made platforms and their limits
To start, ready-made e-commerce platforms are often a good choice: they cost little at launch, come with themes and features ready, and get you online fast. If your catalogue is simple and your flows are standard, there’s no point building from scratch.
The limits come as you grow: fees that rise with revenue, per-transaction commissions, features locked behind higher plans, and integrations with your software that don’t exist or cost dearly. At that point it makes sense to weigh custom, or a mix: the platform where it’s enough, the built piece where the limits are costing you sales.
The most common mistake: opening it and abandoning it
The costliest mistake isn’t in choosing the platform: it’s opening the e-commerce and forgetting about it. An online store needs to be kept fast, updated and secure, with the catalogue cared for and the pages tuned. That’s the “managed” part, the one that turns a frozen site into a channel that actually sells.
An abandoned e-commerce ages faster than a showcase site, because payments and customer data run through it. We build it and then we look after it: updates, security, performance and the catalogue changes, with one clear fee. So you can think about selling, not about keeping the machine standing.
Product pages and SEO: getting found
An e-commerce lives on search. Most orders don’t come from the home page, but from people searching for a specific product on Google and landing straight on the product page. If those pages are empty, slow or all the same, the store stays invisible however good-looking it is. Clear titles, useful descriptions, clean photos and structured data are what make you appear, and appearing is the condition for selling.
It holds for searches made through AI assistants too, which are becoming a second channel of discovery. A well-described product, with precise information, is more likely to be cited or suggested. Caring for the pages isn’t cosmetic work: it’s how your catalogue gets found by people already looking for what you sell.
The recurring costs, beyond the build
People opening an e-commerce often look only at the starting cost and forget what runs every month. Payment fees take a slice of every order. Shipping has a cost and a logistics to manage. Hosting and maintenance keep the store fast and secure. And if you use a subscription platform, the fee often rises with revenue.
None of these lines is hidden if someone puts them in front of you first. The problem starts when a quote shows only the build and stays silent on the rest, and you find the numbers different from how you’d imagined them. That’s why, when we talk about how much an e-commerce costs, we put the recurring costs on the table too: they’re part of the price of selling online, not a detail to discover later.
Phone first: where customers buy
Today most online purchases start on the phone. If your e-commerce is designed for desktop and then adapted to mobile, you can tell straight away: small buttons, an awkward checkout, images that load slowly. And the customer on the phone has even less patience: if a step is a struggle, they close it and go elsewhere.
A well-made store starts from mobile and grows toward desktop, not the other way round. The checkout has to be comfortable with a thumb, the pages light, the load times short. It isn’t a cosmetic detail: it’s where the purchases happen, so it’s where the sale is lost or won.
How we give the price
You won’t find a fake price list. We start from what you sell, how many products you have, which systems the store has to talk to and how much traffic you expect. From there we give you a clear quote before we begin, with the build and the fee separate, so you know what you pay and why.
If you’re just starting, the advice is not to load the project with everything at once. You open with the pieces that make you sell, go live, and add the rest on the real numbers. An e-commerce grows better that way, on use, than with a hundred features switched on the first day and never used.
Questions
- Can I connect it to the software I already have?
- Often yes, via integrations: products, prices and stock synced both ways, with nothing re-entered by hand. See our e-commerce solution.
- Ready-made platform or custom e-commerce?
- To start, a ready-made platform is often enough. Custom is worth it as you grow and the limits (fees, commissions, missing integrations) cost you sales. Often the answer is a mix, and we tell you on your case.
