There's a promise that the subscription e-commerce (SaaS) industry repeats like a mantra: "Open your online store for just 28 euros a month". It's a powerful, democratic, irresistible message. And for a micro-business billing a thousand euros a month, it's even true.
But what happens when your e-commerce actually starts working? What happens when you go from 10 orders a month to 500, 1,000, or 5,000 orders? That's the moment when the "28 euros" promise reveals itself for what it is: a Trojan horse designed to take a fixed percentage of every single cent your company earns.
In 2026, the cost structure of rented platforms like Shopify has become increasingly complex and layered. Many Italian entrepreneurs only realize the real total cost of ownership (TCO) when they analyze the year-end balance sheet and discover that the "cheap" platform has become one of the most expensive suppliers in the entire company.
Anatomy of a Bloodletting: The Real Costs of Shopify in 2026
To understand the real impact of costs, we need to stop looking at the monthly subscription price and start analyzing the three expense items that silently erode net margins.
1. The Unavoidable Tax: Transaction Fees
If you use Shopify Payments (the built-in gateway), the Italian Basic plan charges a fee of 1.9% + €0.25 for every transaction with European cards (rising to 3.6% for non-European cards). It may seem like a negligible percentage, but let's calculate it on real revenue.
Imagine an e-commerce store that generates €50,000 a month with an average order value (AOV) of €100 (so 500 orders a month).
The cost of the Basic subscription is €28.
The fees withheld by Shopify Payments amount to €1,075 a month (€950 in percentage fees + €125 in fixed fees).
You're paying your platform almost 40 times more than its list price. And this happens in a sector, online retail, where the average net margin hovers dangerously between 5% and 15%. That 1.9% isn't deducted from your gross revenue, it's deducted directly from your net profit.
2. The Penalty for Freedom: Third-Party Gateways
You might think: "No problem, I'll use my own bank gateway or PayPal to get better rates". This is where what insiders call the "Shopify penalty" kicks in.
If you decide not to use Shopify Payments, the platform charges an additional fee (up to 2.0% on the Basic plan) on every sale processed through an external gateway. This means you'll pay your bank's fees plus Shopify's tax. It's a closed system designed to discourage any alternative, locking the entrepreneur into a financial ecosystem that's expensive to leave.
3. The "App Tax": The Illusion of a Complete Core
The third pillar of hidden costs is the App ecosystem. The base Shopify engine is excellent, but it's essential. To turn it into a competitive sales machine in 2026, you need plugins for:
-
Italian electronic invoicing (often a monthly paid service)
-
Advanced search filters (essential above 100 products)
-
Advanced multilingual management
-
Integrations with specific couriers (e.g. BRT, GLS, SDA)
-
Cross-selling and up-selling systems in the cart
A well-structured Italian e-commerce store uses on average between 5 and 10 paid apps, adding a fixed cost ranging from €150 to €500 a month. Beyond the financial cost, every app adds external JavaScript code that weighs down the site, worsening Core Web Vitals and, as a result, conversion rates.
The 3-Year Comparison: Renting vs Owning
Let's put the numbers into perspective over a 3-year time horizon for our e-commerce doing €50,000/month (500 orders):
| Cost Item (3 Years) | Shopify (Basic Plan) | Proprietary Solution (KeideaCMS) |
|---|---|---|
| Development / Initial Setup | € 5,000 (Average agency setup) | Custom quote (One-time) |
| Platform Subscription | € 1,008 (€28 x 36 months) | € 0 (No CMS subscription) |
| Platform Transaction Fees | € 38,700 (€1,075 x 36 months) | € 0 (No cut on sales) |
| Essential App / Plugin Costs | € 7,200 (~€200 x 36 months) | € 0 (Core features built in) |
| Estimated Total Cost (3 Years) | € 51,908 | Only initial development cost + Hosting |
The numbers speak for themselves: with a SaaS model, you're paying for the development of an enterprise e-commerce platform every single year, without ever owning it.

Discover e-commerce with no commissions →The Alternative: Proprietary Infrastructure and Financial Independence
The KeideaCMS approach overturns this extractive paradigm. We are not a rented platform, but enterprise software infrastructure that becomes an asset of your company.
With KeideaCMS, the business model is transparent and growth-oriented:
-
Zero Commissions on Sales: Your revenue is yours. KeideaCMS does not retain any percentage on your transactions. You are free to negotiate the best rates directly with your bank, with Stripe, Nexi or PayPal, without paying "penalties" to unrequested intermediaries.
-
Native Features, Not Rented: Forget the App Store. The critical features for a structured B2B or B2C e-commerce (custom price lists, agent management, advanced filters, WAF security) are written into the core of the system. You don't pay monthly subscriptions to keep your store running.
-
Full ERP Integration: While SaaS platforms offer generic connectors that often break with updates, KeideaCMS is designed to natively communicate with your company's management software (Zucchetti, TeamSystem, SAP), synchronizing inventory and orders in real time.
-
AI as a Sales Engine (Coming Soon): We are integrating our proprietary AI Sales Assistant directly into the CMS. Not just a simple chatbot, but an artificial intelligence system capable of analyzing user behavior and offering dynamic cross-selling, increasing the average order value with no cost per transaction.
Stop Funding the Platform, Start Funding Your Growth
If your e-commerce is growing, every percentage point given up in commissions is budget taken away from your marketing, customer acquisition or, simply, your net profit. It's time to move from a "rented" model to infrastructure you own, designed to scale without financially penalizing you.
