Most people preparing to launch a webshop sooner or later arrive at the same question: what should I actually sell to make the store take off? At first, the answer seems simple. Find a product with strong demand, source it at a good price, and start selling. Today's e-commerce, however, is a bit more complex than that – in fact, much more complex. Even a fast-selling product can turn into a bad business, while a niche that looks narrow at first glance can be the foundation of a surprisingly profitable webshop.
Hungarian online retail is still growing, so the market itself has not slipped into recession, nor is it stagnating. According to PwC data, Hungarian shoppers' online product turnover – including purchases from abroad – reached HUF 2,092 billion in 2025. In the first quarter of 2026, domestic online retail expanded by more than 14 percent. At first glance, this is a distinctly favorable environment for anyone thinking about launching a new webshop. Behind the numbers, though, it is worth looking at how the market itself has changed.
To the merchants' dismay, the Hungarian online shopper base is no longer growing at the pace it did a few years ago. According to PwC, roughly 4.4 million Hungarians buy products online, but only one in four of them can be considered a regular online shopper. This group generates nearly 80 percent of parcel volume. Growth in the coming years will therefore be determined less and less by how many new people try online ordering for the first time, and much more by how often and at what value existing customers order.
Why was it important to lay this out in an article like this? Because this shift is far from irrelevant to product selection – not in the least. In 2026, checking whether lots of people search for a given product is no longer enough. What matters more is whether it retains an adequate margin, how expensive it is to acquire the customer, what it costs to serve them, whether they come back for another order, and whether you have some advantage that makes people choose you rather than your cheapest competitor.
What sells a lot is not necessarily good business
Many people make the mistake of simplifying market research to the extreme; the entrepreneur checks which product categories are popular online, and considers the task done. If lots of people buy clothes, launch a clothing webshop. If everyone orders phone accessories, then selling cables and cases must be a good idea. It seems logical, but in practice it is precisely in the biggest markets that you can end up in the toughest position.
Eurostat data illustrates the phenomenon well; among those who had ordered online in the preceding three months, 70 percent bought clothing, shoes or accessories. 31 percent ordered cosmetics or beauty products. Demand undoubtedly exists – but it in no way follows that these are the easiest markets for a new merchant to win. Quite the contrary.
Fashion is a good example of why starting solely from demand is misleading. You have to keep countless sizes, colors and models in stock, the customer sees the offers of dozens of domestic and international retailers on the same screen, and the return rate can also represent a serious cost – something superficial “market researchers” also tend to forget. In DHL's research, 54 percent of shoppers who returned an online product cited incorrect sizing as a reason for at least one of their returns, which is why, in a clothing webshop, the same hundred million forints of revenue can produce a completely different profit than in a category with a low return rate.
The situation is similar with cheap electronics accessories and generic, easily sourced imported goods. When the same or nearly the same item is available in dozens of places, the customer can compare prices in a few clicks. In that situation it is very hard to turn anything other than a lower price into a competitive advantage – and price wars rarely favor the smaller players.
The problem has become even sharper in recent years. According to PwC, foreign retailers already accounted for nearly 18 percent of total Hungarian online product turnover and 24 percent of orders in 2025. Temu's turnover in Hungary alone was roughly HUF 195 billion, with more than 13 million orders. And in the first quarter of 2026, about 1.8 million Hungarian shoppers ordered from the platform. For a small Hungarian webshop, it is no walk in the park to compete with products for which the Chinese marketplaces serve the same customer need with a vastly larger selection and extremely aggressive pricing.
Look for a working business model, not a product
Good product selection should be treated not as trend-chasing but as a business modeling exercise. For a new product category, you need to understand at least how large the real demand is, what margin you can work with, how strong the competition is, how often the customer buys again, what the logistics cost, and how easy it is to find the same product elsewhere.
Margin analysis in particular tends to breed misunderstandings – sometimes descending into total chaos that calls the accuracy of the entire plan into question. If you source a product for a net HUF 5,000 and sell it for HUF 10,000, it does not follow that you earned HUF 5,000. You have to pay for packaging, the payment provider, logistics, possibly part of the shipping, discounts, returns and, of course, customer acquisition.
In practice, therefore, what matters far more is the margin remaining per order. From net revenue, deduct the purchase cost, packaging, logistics and payment costs, discounts and the expected cost of returns. Whatever remains after all that has to fund marketing, staff, the webshop's technology costs, warehousing and, finally, the owner's profit. If the math works out, great; if not, you'll need to rethink things.
It is not uncommon for the biggest difference between two webshops with similar revenue to show up exactly here. One is healthily profitable at HUF 100 million in annual turnover, the other struggles with constant financing problems at the same revenue. Hungarian e-commerce is a textbook case: the player that led the market for many years managed to book losses of HUF 10 billion a year.
Repeat purchases can be worth more than a single big order
In the modern e-commerce environment, products that the same customer reorders regularly have become especially valuable. The reason is simple: acquiring a new customer costs money, while the next purchase from an existing customer can typically be achieved with a far smaller marketing spend. Most people buy a mattress or a dining table for many years. By contrast, pet food, cosmetics, cleaning products or the consumables a business needs to operate run out within weeks or months. If the first order delivered a good experience, the customer has no particular reason to look for a new merchant.
All this matters even more because the ordering frequency of existing customers is playing an ever greater role in the further growth of the Hungarian market. Merchants should therefore think not only in terms of conversion but also in terms of customer lifetime value. To put it differently: what counts is not just how much someone spends today, but how much they will spend with you over the next two or three years.
And this is the angle from which it is worth attacking the “what should I sell” question...
The pet market still holds serious opportunity
Pet-related products are interesting because several favorable e-commerce characteristics come together in them. Pet food, treats, litter and many grooming products are consumed regularly, and a portion of pet owners are distinctly loyal to products that have proven themselves. This creates a good foundation for repeat purchases.
The size of the Hungarian market is signaled by the fact that Petissimo and Fressnapf both appeared in PwC's online FMCG ranking. But this is not solely a Hungarian trend. According to NIQ's 2026 retail analysis, the e-commerce value of the pet care category in Germany grew by 65 percent in two years. This does not mean that every pet food webshop automatically has a great opportunity ahead of it – but it does mean that significant online demand remains in the category.
As a new entrant, however, the best strategy is probably not to try to offer the same thousands of products as the biggest players. It can be far more interesting to focus on a well-defined territory. That might be a particular animal species, a specific dietary need, dog sports, training, premium grooming, or another sub-market where expertise carries value alongside the products.
Beauty: a strong market that is hard to enter with a generic webshop
The beauty market remains one of the categories where serious online growth can be expected over the longer term. McKinsey projects roughly 5 percent annual growth for the global skincare, makeup, haircare and fragrance market through 2030. According to their analysis, by then e-commerce's share of global beauty sales could exceed 30 percent.
Some subcategories are developing even faster. Based on Circana data, the combined market for sun care products in France, Germany, Italy, the Netherlands, Spain and the United Kingdom reached around EUR 1.6 billion, growing 11.6 percent in the 52 weeks ending March 2026. Some product categories once considered strictly seasonal are thus slowly becoming year-round consumption areas.
For a smaller merchant, however, a generic cosmetics webshop is not necessarily the way to think here either. A range built around sensitive skin, professional haircare, men's cosmetics, sun protection or a specific beauty concern is far easier to position. In such a situation, the customer is not simply searching for product names but expecting help in making the right choice. This is also interesting because, according to McKinsey research, consumers are increasingly sensitive to whether they actually get the value a product promises. Quality and demonstrable benefit are in many cases becoming more important than pure marketing. A merchant that builds on professional content, detailed product information and good advice can find room to maneuver here, even in a market where many large players already operate.
Wellness: a strong trend where product selection matters even more
Wellness today means far more than gym accessories or sports equipment. The category now encompasses functional nutrition, healthy aging, recovery, sleep, beauty care and numerous consumer areas that used to be treated separately.
McKinsey's 2025 survey estimated the global wellness economy at approximately USD 2,000 billion. The research, involving more than nine thousand consumers, identified functional nutrition, healthy aging, beauty care and weight management, among others, as areas where further significant consumer demand can be expected.
Part of the category's appeal from an e-commerce standpoint comes from the fact that many products are repurchased regularly. At the same time, not every sub-market is suitable for a beginner merchant to enter easily. With dietary supplements, certain health products and health-related marketing claims, you also have to reckon with legal, compliance and communication issues.
Excellent businesses can hide among the less glamorous categories too
On social media, attention usually goes to products that are new, visually striking or easy to demonstrate in a short video. This can easily create the impression that only such products are worth building a webshop on. In reality, many well-functioning webshops sell far more mundane products.
The household consumables market is a good example. According to NIQ's 2026 European data, online sales of the home care category in Germany grew by 15 percent in two years. At first, it does not look like a particularly exciting market – but many products are consumed regularly and the consumption cycle is predictable, because limescale never rests and dishes need washing whether we like it or not.
A generic cleaning-products webshop is hard to differentiate from the competition. It is quite another thing to offer a range assembled for professional cleaning, special surfaces, sensitive households or a specific use case. Then the merchant is not merely selling boxes but helping decide which product a specific task requires – and there is your market advantage, one that even the big players cannot always deliver.
Parts and accessories: where good information is a competitive advantage in itself
Spare parts, filters, adapters, accessories and other compatibility-driven products represent a genuinely interesting territory. They rarely appear on lists of “best webshop ideas”, yet for a smaller merchant they often offer a more favorable market than eye-catching consumer goods. The customer does not arrive here looking for inspiration. They have a vacuum cleaner, coffee machine, appliance, tool or other device that needs a specific part, because they want to use their machine – so purchase intent is often extremely strong. Once they find the right product, they are unlikely to want it weeks later; they want it as soon as possible – preferably delivered yesterday.
What's more, the competitive advantage does not have to be price alone. An accurate compatibility database, a genuinely usable search, sensible filtering, detailed descriptions and clearly showing which models a part fits are worth a great deal. Many webshops offer a distinctly poor user experience at exactly this point. And it is an interesting territory from an SEO perspective too. Search volume for any single main product name may be modest, but the sum of searches tied to hundreds or thousands of model names, type numbers and specific problems can add up to significant organic traffic. In this business model, a good product database and professional information are not simply content marketing but a direct commercial tool.
B2B webshops: often overlooked, yet a serious opportunity
When people hear the word webshop, almost everyone thinks of consumer shoppers, yet a well-chosen B2B niche can in many cases be even more attractive; workshops, beauty salons, offices, restaurants, small manufacturers, contractors and service companies continuously order the products their daily operations require. A retail customer might buy once a year, while a business orders the same product every single month.
For a smaller company, a good strategy may therefore be not to serve an entire industry, but to build on a single trade's specific procurement problem. Often you do not need a huge market; a few hundred regularly ordering businesses are enough to create a stable, highly predictable operation.
Some categories deserve particular caution in 2026
Since Temu's explosive arrival, it has been difficult to enter the market for generic, cheap Chinese mass-market products without a private label or some other serious differentiation. A smaller webshop typically works with worse purchase prices, a smaller selection and a much lower marketing budget. If the customer discovers the same product on the Chinese platforms, the comparison almost automatically narrows down to price.
Mass-market fashion can be similarly risky. Demand is undoubtedly high, but the inventory requirements, sizing, seasonal risk and returns call for serious capital and operational experience. With a private label or a clearly defined target audience, the situation can of course be different.
General electronics retail is likewise a hard market to attack. Products are easy to compare, price competition is fierce, warranty administration can be costly, and – not incidentally – many large retailers operate on very thin margins. Here, specialized accessories, a specific application area or a B2B focus often offer a more interesting entry point.
With large, heavy or fragile products, it is above all the logistics that must be modeled very rigorously. A higher cart value can of course offset more expensive delivery, but the cost of one damaged or returned product can easily wipe out the profit of several successful orders.
How to conduct market research before launching a webshop
Market assessment is best begun with a multi-year examination of demand. A social media trend that spikes within a few months represents an entirely different risk than a product category that has been growing slowly but steadily for five years. Google Trends can be a simple yet useful first filter in this respect.
Next, examine search data. Not only the search volume of the main category name matters, but all the smaller, more specific searches as well. Many good niches look at first as if there were barely any demand, when in reality a substantial market is composed of hundreds of smaller keywords.
In competitor analysis, counting how many webshops exist is not enough. You need to see how good these merchants actually are. What is their product selection like? How fast do they ship? What prices do they work with? How detailed are their product descriptions? Is their webshop easy to use on a mobile phone? Do they have professional content? What customer problems appear in the reviews?
Marketplaces and customer reviews also provide a wealth of useful information. If the same complaint appears in thirty out of a hundred reviews, that is no longer an isolated grievance but a potential gap in the market.
Examining the supplier side is at least as important. Beyond the purchase price, what matters is the minimum order quantity, delivery time, stock reliability, payment terms, complaint handling – and how many other Hungarian merchants receive the same goods from the same source. A promising-looking market gap can vanish quickly if ten competitors show up with the same product within a few months.
Logistics must be factored in at the moment of product selection
Shipping is not a technical detail to be sorted out later – with certain products it can decide the profitability of the entire business model.
DHL's 2026 international study examined responses from 29,000 online shoppers and 5,800 e-merchants. 67 percent of consumers said they had already abandoned a purchase because the available shipping option did not suit them. 58 percent had also walked away from an order because of the return conditions.
In Hungary, the rapid spread of parcel lockers adds to this. According to PwC data, by 2026 nearly half of Hungarian shoppers prefer this pickup method, and the number of lockers has already exceeded ten thousand. A small, light, non-fragile product is significantly more advantageous in this respect than goods that always require home delivery or oversized parcel handling. When selecting products, therefore, think through very concretely the package size, weight, fragility, storability and the cost of return shipping. Of two products with identical margins, the one that fits into a parcel locker and the one that can only be moved on a pallet are, in business terms, far from certain to be equally valuable.
Market research must be closed with real purchases
However detailed your market research, there is a point beyond which no amount of further analysis can determine whether the business idea works. Google search data, competitors' traffic estimates, marketplace reviews and supplier quotes are all useful, but none of them replaces a real customer. It is therefore usually more sensible to enter the market with a smaller product range and controlled inventory. In the first months, you can already measure which categories attract visitors, which products get added to carts, which turn into actual orders, what increases cart value, and which products end up in the same cart – in other words, what is bought together.
This is where the role of the webshop platform becomes especially important. If trying out a new idea requires months of system development, the technology itself slows down your market learning. On a rented platform, by contrast, you can get much sooner to the point where you are talking about real order data rather than assumptions.
Sellvio, for example, offers reports showing turnover, cart value, product top lists, inventory value and sales trends, and product data can be imported and edited in bulk. This makes it possible for the merchant to treat the initial product range not as a final decision, but as a commercial tool that can be continuously adjusted and improved. What works, source a wider selection of; what doesn't, manage with optimal effort.
Dream bigger than the Hungarian market from the moment you pick your products
Hungary is a sufficient market for many product categories, but in certain narrower niches you can hit the natural growth ceiling quickly. In such cases, it is worth examining right at launch whether the same range could later be sold in other Central European countries as well.
A specialist market that is relatively small in Hungary can become a substantially more interesting size when combined with Slovakia, Romania, Croatia or even additional EU countries. This works especially well for products that are easy to ship, require no on-site service, and address a customer problem that is not uniquely Hungarian. International expansion, however, involves far more than translating product descriptions. You need the local language, the right currency, the payment options people are used to, competitive shipping and a merchant presence that is credible to shoppers in that country.
Sellvio provides multilingual operation, per-language URL structures, country and currency settings, and an API connection usable with external systems. When evaluating a new product category, therefore, calculate not only how big a business can be built on it in Hungary, but also whether it holds potential for later regional growth.
So what should you actually sell in 2026?
There is no single product about which one could responsibly declare that it will definitely be good business in 2026. If there were, so many merchants would start selling it within a short time that this very fact would strip it of being a special opportunity.
Choosing the category alone, however, is still not enough. A pet webshop can be an excellent business or a complete failure. The same goes for cosmetics, spare parts or B2B products. The difference is most often decided not by whether the given market is growing in general, but by which target audience the merchant chooses, at what price they can source, what it costs to acquire a customer, how likely repeat purchases are, and whether they can offer something the big marketplaces cannot.
This may be the most important change compared with launching a webshop a few years ago. Today, finding a good product is no longer enough on its own. The real task is finding a market position in which the customer has a clear reason to order not just anywhere, but from you specifically.
