Online store cost: the real budget

How much does an online store really cost? The cost of creating an online store varies enormously depending on the platform you choose — and above all on what you forget to count at the start: payment fees, domain name, tools added over the months, visibility budget. This guide is for you if you're preparing your launch and want a realistic budget, line by line, with no nasty surprise in month three. We'll go through the expenses that are truly mandatory and those that can wait, the most frequent hidden fees, and the safest way to start light: paying at the pace of your sales rather than before you've sold anything.

What makes up the real cost of your store

A platform's advertised price only tells part of the story. The real cost of an online store spreads across several lines, which don't all arrive at the same time:

• The platform: what you pay for your store to exist — subscription, commission, or both.
• The payment: the fees the provider takes on each transaction.
• The identity: domain name, design, photos of your products.
• The visibility: possible advertising and marketing tools — the most underestimated line.

The platform, the cost that shapes everything else

It's the choice that determines your level of financial risk.

The subscription model

You pay a fixed amount every month, whether you sell or not. As long as sales follow, all is well; in the first months, however, the subscription keeps running while you build — a silent countdown. On top of that often come a paid theme and separately billed apps, which inflate the real amount well beyond the entry price.

The commission model

Here, opening the store costs nothing: the platform takes a small percentage on each sale. Your cost is aligned with your activity — zero sales, zero platform fees. It's the safest model for starting out, that of a free e-commerce platform in the honest sense of the term. The full calculation between the two models is detailed in our commission vs subscription comparison.

At Naaora, this is the model: you start at €0, the commission runs from 0.4% to 1% depending on the plan, and your first 10 sales are free.

Online payment fees

Whatever the platform, taking card payments goes through a payment provider, which takes fees on each transaction. This line is unavoidable — it pays for the security and processing of the payment — but it deserves your attention:

• Check who bills what: some models stack platform fees and payment fees, others don't.
• Build them into your margin: calculate the net you keep per sale, not the displayed price.
• Beware of additions: platform + provider + possible currency conversion fees internationally.

Domain name, design and branding

• The domain name: a small annual expense, useful for your credibility — but nothing forces you to buy it on day one. The address provided by your platform is enough to validate your idea.
• The design: the templates included in good platforms are largely enough at launch. A premium theme or a designer is an investment for later, once sales justify it.
• The photos: the line where elbow grease replaces budget. Natural light, a neutral background, a recent phone: enough to make clean product pages without a studio.

The visibility budget, the great forgotten expense

The most underestimated expense at launch isn't the store: it's bringing in visitors.

• Free channels first: social media, communities, word of mouth, organic search. They cost time, not money — perfect at the start.
• Advertising later, if needed: it accelerates what already works, but it also amplifies what doesn't. Running ads on an untested store is paying to discover its flaws.
• Your time, finally: it's the real starting capital. Every hour spent on your product pages and your visibility replaces ad spend.

Hidden fees to watch out for

Budgets rarely explode all at once — they swell in small touches:

• Apps added one by one: each one seems essential and modest; their sum becomes a second subscription.
• Free trials that convert: the tool tried in January and never canceled is still being paid for in June.
• The theme and premium options: bought to "look professional" before validating that the store sells.
• International fees: currency conversion, shipping abroad — to anticipate if you're targeting several countries.

The right reflex: a monthly review of everything being charged. What isn't used gets canceled.

Starting light and paying as you sell

The least risky strategy fits in three principles:

• Pay for nothing irreversible before your first sale: no massive stock, no stacked subscriptions, no costly services.
• Invest your time where it replaces money: photos, product pages, content, communities.
• Choose a model aligned with your sales: a commission-based platform turns your fixed cost into a variable cost — your store only costs you when it earns you something.

That's exactly the step-by-step logic of our guide to creating an online store without coding: launch cleanly, validate, then reinvest.

Conclusion

The cost of creating an online store depends less on the platform than on the model: paying a flat fee before selling, or a commission while selling. Add the payment fees, keep the domain and the design for later, watch the small expenses that pile up, and save your budget for the line that matters: bringing in buyers. Next step: put your total monthly cost down on paper, and choose the model your sales can cover.

FAQ

How much does it cost to create an online store?

From €0 to much more, depending on the model you choose. On a commission-based platform, opening costs nothing: you pay a percentage when you sell. On a subscription platform, you pay every month, sales or not — plus the theme, the apps and the payment fees.

Can you really create an online store for free?

Yes, if "for free" means with no upfront expense: some platforms only charge a commission per sale. The payment provider's fees, however, exist everywhere. What counts: no fixed cost until you've sold, and a known net per sale in advance.

What are the hidden fees of an online store?

The most frequent: apps added one by one, the premium theme, free trials never canceled, and transaction fees you forget to count in your margin. A monthly review of your charges and a total cost calculation are enough to keep them under control.

Subscription or commission: which model is cheaper?

It depends on your sales volume. At launch and at low volume, commission wins almost always: zero sales, zero fees. At high volume, a fixed subscription can become competitive. Do the math with your real numbers — our dedicated comparison helps you step by step.

What advertising budget should you plan at launch?

None is mandatory. Start with free channels — social media, communities, organic search — to test your store and your product pages. Advertising comes later, to amplify what has already proven it works: paying to send traffic to an unvalidated store amounts to funding its own flaws.
