Selling online is appealing. But ecommerce is not a business website with a buy button: it is a different job, with different costs and demands that never stop. Here is how to work out which of the two earns you more.
What each one actually does
A business website turns a visitor into an enquiry. It reassures, provides evidence and encourages people to call. The sale happens afterwards, through a person, over the phone or in a meeting.
An ecommerce website turns a visitor into a customer without anyone intervening. That is more powerful and much more demanding: you need up-to-date stock, shipping, returns, customer service and payment processing that never fails. Isack Hadjar’s official shop offers an example of an online purchasing journey.
The calculation that decides
It comes down to three numbers: your average order value, your margin and how many orders you can expect each month.
An online shop costs between €3,000 and €60,000 to build, then between €100 and €500 per month to run properly, excluding management time. For it to be worthwhile, the margin from online sales must exceed that total.
Take an average order value of €60 with a 40 per cent margin, giving €24 margin per order. At €300 in monthly costs, you need thirteen orders per month to break even, without accounting for the initial build or your time. That is achievable. At an average order value of €15, you need fifty, and it becomes a different story.

When a business website wins clearly
- Services quoted individually: construction, consultancy and events. The price depends on the project, so there is nothing to put in a basket.
- High-value purchases that need reassurance: nobody buys a €12,000 conservatory in three clicks. The website needs to generate calls.
- Local services with appointments: hairdressing, restaurants and healthcare. Appointment booking is enough; a shop makes no sense.
- A very small catalogue: three products sell just as well over the phone or by message, without the infrastructure.
When ecommerce is the clear choice
- A standardised product that does not need explaining.
- Volume: many mid-value orders, where handling each one by phone would be impossible.
- Repeat purchases: the customer comes back, making a customer account particularly valuable.
- Sales outside your geographical area, where there is no alternative anyway.

The middle route is often the right one
A solid business website with one or two products available to buy online. You test real demand before investing in a complete shop and discover the actual demands at a volume you can handle manually.
This also avoids the most common mistake: paying for a shop with 200 products that makes no sales because nobody finds the website. A shop without traffic is a closed storefront on an empty street, only more expensive.
What nobody tells you about ecommerce
The website is the easy part. The hard work comes afterwards: photos for every product, descriptions to write, stock to keep current, parcels to prepare, returns to process, payment disputes and customer service that answers on Saturdays.
Allow one to three hours of management each day once orders start coming in. If those hours do not exist in your week, the shop will become a source of unhappy customers, costing more than not selling online.
Ask yourself these questions in this order: is someone searching for my product online, can my margin cover the costs, and do I have the time to run it? Three yeses make ecommerce the right choice. One no, and a business website will earn more.
Frequently asked questions
01At what revenue level does ecommerce become profitable?
There is no universal threshold, but there is a calculation: margin per order multiplied by a realistic number of monthly orders, compared with €300 to €500 in costs plus your management time. An average order of €60 with a 40 per cent margin reaches break-even at around thirteen orders per month.
02Can a business website become an online shop later?
Yes, and that is often the best sequence. On WordPress, WooCommerce can be added. On Wix or Squarespace, shop functionality is available on higher plans. Starting with a business website closes no doors.
03How much does an ecommerce website cost?
From €3,000 to €10,000 using a template with a simple catalogue, and €15,000 to €60,000 when there are complex variants, a connection to management software or several countries. Add €100 to €500 per month in operating costs.
04Should I sell on my own website or a marketplace?
A marketplace brings immediate traffic but takes 8 to 20 per cent and does not give you the customer relationship. Your website earns nothing until it has visitors, but the margin and customer database belong to you. Many businesses start on a marketplace to validate demand, then switch.
