Why many online stores aren't profitable (even with traffic)

One of the most common mistakes in e-commerce is thinking that more traffic automatically means more profit. In reality, many Swiss SMEs run online shops with thousands of monthly visits, active campaigns and regular orders… but with very low margins or even losses.
The customers are often there: what weighs the business down is underestimated margins, hidden costs and poorly optimised payment systems. The reasons are almost always the same.
Margins: the first big misunderstanding
Many business owners calculate the selling price using a simple formula:
product cost + mark-up = final price.
Unfortunately, in e-commerce this logic isn't enough.
Besides the product cost, several other factors come into play:
- payment fees
- shipping and returns costs
- platform and plugin costs
- marketing and advertising
- order management and customer support
If the gross margin isn't sufficient, every order creates work but little value.
A healthy e-commerce business should know precisely:
- margin per product
- margin per sales channel
- net margin per order
Without this data, you're selling "in the dark".
Hidden costs: the ones that turn up at the end of the month
Many online stores aren't profitable because costs arrive in small pieces, month after month, and aren't visible at first.
Technical costs
- hosting
- updates
- maintenance
- paid plugins
- integrations
Individually they seem minimal, but added together they weigh heavily.
Operating costs
- time spent managing orders
- customer support
- handling returns
- manual errors
The time spent has a real cost, even if it isn't always accounted for.
Marketing costs
- ongoing advertising
- underperforming campaigns
- unqualified traffic
Payments: the most underestimated point
One of the most critical (and least analysed) aspects is the payment system. Many online stores use convenient but expensive solutions.
Typical costs include:
- transaction percentages
- fixed fees per order
- monthly subscriptions
- acquiring costs
In Switzerland, depending on the provider, a transaction can cost much more than you'd think, especially on low-value orders.
A practical example:
- order of CHF 30
- fee of 2.9% + CHF 0.30
- real cost close to or above 4%
Multiplied across hundreds of orders, the margin shrinks dramatically.
Choosing the right payment systems and optimising them according to volume and customer type is essential for profitability.
Traffic, yes, but the right traffic
Many shops invest in traffic without asking:
- who is arriving?
- what are they looking for?
- are they ready to buy?
Unqualified traffic increases:
- advertising costs
- abandoned carts
- unnecessary support requests
It's better to have less traffic, but more targeted, with:
- clear funnels
- consistent offers
- simple messages
When e-commerce becomes an "extra job"
A clear sign of poor profitability is when the online shop:
- takes up too much time
- generates stress
- doesn't scale
- depends on a single person
In these cases, e-commerce becomes an operational burden. The business model often holds up, and what isn't working is the organisation.
The importance of an integrated approach
A profitable e-commerce business is a system that holds together:
- prices and margins
- optimised payments
- efficient logistics
- measurable marketing
- automated processes
Without this overall view, you risk working hard to earn little.
