The advice you find in English usually starts with buying inventory. That is the fastest way to lose money you did not have, and it is not how most people in Czechia start. Second-hand goods, made-to-order work, services and digital files all move here through channels that ask nothing up front — and the real question is not which one is free to join, but which one leaves the most of the sale price in your hands after delivery, returns and payment costs are counted.
This guide compares those channels on that basis. It also covers the part that decides whether a side activity stays pleasant or becomes a problem: the point at which occasional selling turns into a business the tax office recognises, and what changes on that day. Prices in Czechia are calm at the moment rather than spiralling — consumer inflation was 1.5 percent over twelve months in June 2026, below the Czech National Bank target of 2 percent — so the money you make here comes from margin and discipline, not from riding a price wave.
Starting with no capital also means starting with no buffer, which is uncomfortable in the first weeks. Apps such as I am Beezy, which pay you for viewing content on your phone, are one way to keep a small amount arriving while your first listings are still finding buyers.
What does selling without stock really mean in Czechia?
Four different activities hide behind the phrase, and they have different risks. Pick the one that matches what you can actually deliver this month.
Selling what you already own
This is the only version with zero downside. The goods are yours, the money is already spent, and every sale is recovery rather than profit. It is also the best training ground: you learn how buyers here behave, how the pickup networks work and how long payment takes, without risking anything. Most people who later sell seriously in Czechia started by clearing a cupboard.
Made to order, made after payment
If you make or assemble something, taking the order first and buying materials second removes the inventory risk entirely. The trade-off is delivery time, and you have to be honest about it in the listing. A buyer who was told ten days waits; a buyer who was told two days complains on day three, and in Czechia that complaint has a legal shape you will meet later in this article.
Services and digital goods
Translation, repairs, photography, lessons, templates and files carry no stock at all, and they are the least crowded corner of the Czech classifieds. They also change your tax position more than second-hand selling does, because they are unambiguously an activity rather than a disposal of your own property.
The channels a Czech seller actually has
Czechia has an unusual amount of choice at the small end. Where most countries have one dominant classifieds site, this market has three, and they coexist with marketplaces and with cheap tools for running your own shop.
The classifieds trio, plus Vinted
Sbazar, Bazoš and Aukro all work, and they attract different buyers: two are straightforward listing sites, the third is built around auctions. Vinted covers clothing and takes the negotiation out of it. Having three general classifieds sites rather than one means a listing that fails on one of them is worth reposting on another before you conclude the item will not sell. None of them requires you to register a business to list an item you own.
Marketplaces
Allegro now operates in Czechia at allegro.cz, and it is where the old MALL.cz storefront ended up — MALL is no longer a separate marketplace, it is a shop inside Allegro. A marketplace brings you traffic you could never buy and imposes its rules in exchange: its fee schedule, its delivery expectations, its rating system. Alza remains the reference for Czech electronics buyers, which matters when you price second-hand equipment.
Your own shop
Running your own e-shop is cheaper here than most people assume, because platforms such as Shoptet do the technical work for a monthly fee. What they do not do is bring you buyers, which is why Czech shops list themselves on the two comparison engines people here genuinely use, Heureka and Zboží.cz. Your own shop is the only channel where you keep the customer relationship — and the only one where you carry the whole cost of acquiring them.
| Channel | Cost to start | Who brings the buyer | Who handles delivery | Suits |
|---|---|---|---|---|
| Classifieds (Sbazar, Bazoš, Aukro) | Nothing, or a small promotion fee | The site, for local searches | You, usually via a pickup point | Occasional sales of what you own |
| Vinted | Nothing to list | The app | Integrated labels | Clothing, shoes, accessories |
| Marketplace (Allegro) | Registration, then per-sale fees | The marketplace | You, to its standards | Repeatable products with real volume |
| Your own shop on a platform | Monthly fee | Nobody, until you list on comparison engines | You, entirely | Anything you intend to do for years |
Where the money leaks between the sale and your account
The fee page is the smallest of the costs. What actually decides your margin sits in three places nobody advertises.
Delivery and the pickup networks
Czechia runs on parcel pickup points, and the two names to know are Zásilkovna and Balíkovna. Choosing a pickup point over a home address is normally cheaper for both sides, and it removes the failed-delivery problem that eats an afternoon. Build the delivery cost into your price before you list, not after a buyer asks, and say plainly who pays it.
Returns and complaints are a cost, not an accident
If you sell to consumers you inherit obligations, and the Czech Trade Inspection Authority states them plainly in its consumer guide on coi.gov.cz, consulted on 12 August 2026. Where no delivery date has been agreed, the seller must deliver without undue delay and at the latest within 30 days, and a complaint must be settled within 30 days of being lodged unless both sides agree otherwise. The authority also states that a buyer can raise defects that appear within 24 months of delivery, with the first year weighted against the seller. Price a small return rate in from the start.
Getting paid without losing the payment
Cash on handover still works for local sales, and cash has not disappeared here: card payments passed 3.3 billion transactions in 2025 across roughly 285 000 terminals, while 140.4 million cash withdrawals were made in the same year. For everything remote, a bank transfer with the right reference is the cleanest route. Put a QR platba on your invoice, fill in the variabilní symbol, and use instant transfers where you can — they ran at 43.6 million operations in June 2026 and cleared around 46.4 percent of all interbank transfers in April 2026.
| Cost line | Who usually pays | How to control it |
|---|---|---|
| Delivery to a pickup point | The buyer, if stated | State it in the listing, not in the chat |
| Return postage | Depends on the reason | Write your policy once and reuse it |
| Listing promotion | You | Only after an item has failed to sell unpromoted |
| Marketplace fee per sale | You | Check it against your margin before listing, per item |
| Payment received late or unmatched | You, in time | QR code plus variabilní symbol on every invoice |
Covering the first month with I am Beezy
The first weeks of selling produce listings, messages and no money. That is normal, and it is also when people spend on promotion they do not need because nothing is happening.
How the earnings add up
I am Beezy pays you for viewing content — videos, articles, advertisements — with each view generating a small amount credited to the payment method you already use. Across the platform the reference range is 5 to 15 euros a day, which at the Czech National Bank rate of 24.190 koruna to the euro on 5 August 2026 works out at between 120 and 360 koruna a day. The koruna moves, so recheck the daily table on cnb.cz rather than reusing that figure.
Where it fits in the plan
Use it to pay the small costs that make selling work — postage, a promoted listing, packing materials — instead of dipping into the money a sale brought in. It is not a wage and it will not replace the selling. It removes the excuse for quitting in week two.
When does this become a business in the eyes of the tax office?
Selling your old bicycle is not a business. Selling twenty bicycles you bought to resell is. The line is drawn by repetition, intent and organisation, not by a magic number of sales — and once you are across it, the Czech system is unusually simple.
The flat tax replaces three payments with one
A registered self-employed person can enter the paušální daň, which merges income tax, pension contributions and health insurance into one monthly payment made by the twentieth. The Financial Administration sets the first band at 9 162 koruna a month for 2026, made up of 100 koruna of income tax, 5 756 koruna of pension contributions and 3 306 koruna of health insurance. The second band is 16 745 koruna and the third 27 139 koruna. Entry and any change of band must be notified before the tenth day of the tax period.
The band depends on the activity, not only the amount
Which band you land in is decided by both last year's income and its composition, through the expense allowance attached to each type of work. Two sellers with the same turnover can sit in different bands. If you are moving from selling your own things to buying for resale, check what that shift does before the January deadline rather than after it.
Two VAT thresholds since 2025
Turnover is counted per calendar year, and there are two triggers: 2 000 000 koruna, after which you are liable from the following first of January, and 2 536 500 koruna, after which you are liable from the day after you cross it. Either way the registration request goes in within ten working days. The ceiling of the flat-tax regime is the same 2 000 000 koruna, which makes it the one figure to keep in mind. The rules sit on financnisprava.gov.cz, and the online counter is MOJE daně.
A four-week start that needs no capital
The order matters more than the effort. Most people begin by listing and end up improvising the parts that decide whether they get paid.
Week by week
In the first week, list ten things you already own on two different sites and write your delivery and return wording once. In the second, complete every sale through a pickup point so you learn the process, and keep a note of what each sale cost you. In the third, repost what did not sell on the third site and test one price change. In the fourth, add up the real margin per sale and decide whether the activity is worth registering. That decision is much easier with four weeks of your own numbers than with none.
What to keep from day one
Keep the listing text, the agreed price, the delivery evidence and the payment reference for every sale. It costs a minute per sale and it is the only thing that protects you if a buyer raises a defect months later, or if the tax position needs explaining. A single spreadsheet is enough.
Nothing here requires capital, and almost nothing here requires speed. Choose one channel, price the delivery in, put a QR code and a reference on everything you invoice, and let four weeks of real numbers tell you whether to register. And if you want a small amount arriving while those first listings are still cold, you can sign up for free on I am Beezy and start earning from content on your phone today.
