Open a free online store, step by step
Opening the store is the easy part: it takes minutes and costs nothing. The part that matters is what you do in the first week, before the first sale. Here is the sequence, step by step, including what happens after a customer buys.
Step 1: create your account
Start on kairosfy.com and create an account with your email address. The Free plan requires no card and no monthly commitment, and creating the store costs nothing.
You can work from a laptop or from the Android app. The panel is available in Spanish, Portuguese and English, so choose the language you will actually use every day.
Step 2: confirm your email
Look for the confirmation email and open the link inside it. If it does not arrive within a few minutes, check the spam folder before requesting another one.
Confirmation matters. It is how the account is tied to a real inbox, and it is where order notices and support answers will go.
Step 3: name the store and set it up
Choose a store name that a customer can read, spell and remember. The name is what appears on the shipping in place of a marketplace brand, so it is part of the customer experience, not decoration.
Design is included, so you are not starting from a blank page. Pick a look that matches the products you are going to sell and move on; design is not what decides the first sale.
Step 4: choose and publish products
Browse the catalogue and pick items that fit one theme. Set your sale price from the cost side: plan fee plus shipping for the route you expect, then the margin you want. The products guide has worked examples.
Publish a small, coherent set. Write the pages in your own words, check the images, and make sure what the customer receives is obvious before checkout.
Step 5: check payments and shipping
Decide whether the store offers cash on delivery, online payment or both. Check the shipping cost for the routes you expect, Portugal to Portugal, Spain to Spain and Spain to Portugal, and know which one applies to each order.
Only mainland Portugal and peninsular Spain are active destinations for catalogue products.
Step 6: your first order
Kairosfy then prepares and ships the order in the name of your store. Once the order is delivered, the amount reaches your balance, and you can withdraw by SEPA transfer.
Step 7: keep the store alive
A weekly login is enough to stay clear of that.
Support is written, in the language of the seller, which suits people working across time zones. Use it for questions about orders rather than waiting for something to become a problem.
What not to expect
No platform can promise income, delivery dates or a position on Google, and Kairosfy does not. What you get is a store, a catalogue, shipping and payouts, and a cost structure you can calculate before you sell.
What you bring is product choice, clear pages and consistent work. That is the part nobody can automate for you.
Frequently asked questions
How much does it cost to open the store?
Nothing. Creating the store is free and the Free plan is €0 per month. You pay a 2.5% per-order fee, minimum €2.50, plus shipping for the route.
How long does it take?
The store is ready in minutes once you have confirmed your email and chosen the name. Choosing and writing the products takes longer.
Can I open a store from outside Portugal?
Yes. Sellers can be based in the US, Mexico, Brazil or anywhere else. The catalogue sells to customers in mainland Portugal and peninsular Spain.
Do I need stock to start?
No. You pick catalogue products, set prices and publish. There is no stock, no storage and no minimum order.
