Guides for peoplewho do the maths.
We write about what selling online actually costs: commissions, integrations, upkeep, and the point at which your own shop starts to pay for itself. No numbers pulled out of thin air. If we haven't checked something, we leave the space blank.

Allegro commissions: let's work through examples.
The rate in the category table is not the same as the percentage that actually comes off the price of your product. One sentence in the terms makes the difference, and you only see it in worked examples. - 8 min read
What Shopify really costs in Poland. Let's do the maths.
Shopify looks like the simplest choice in the world, and in many ways it is. In Poland, however, the bill has three layers instead of one, and the last one is often the dearest. - 8 min read
What a shop on IdoSell really costs. Let's do the maths.
IdoSell bills differently from the rest of the market: not a percentage of turnover and not a flat subscription, but an amount per order. That changes the whole arithmetic, because the bill grows with the number of parcels, not with their value. - 6 min read
KSeF in an online shop: what changes.
Poland's National e-Invoicing System has stopped being a topic for the future. For most sellers the obligation is already running, and for the smallest it begins at the start of 2027. - 8 min read
What a Shoper store really costs. Let's count.
The advertised price is the first-year subscription. The real bill is the renewal subscription plus integrations, which on Shoper are separate apps with separate price lists. Every figure below comes straight from shoper.pl pages, as of September 1, 2026. - 7 min read
Erli: is another channel worth adding?
A new channel tempts you with the promise of extra orders. Before you count the profit, check what the commission is actually charged on: on Erli the base is wider than the rate table suggests. - 7 min read
Migrating a shop without losing SEO.
The usual failed migration is not a case of the new shop being worse. It is a case of the old addresses ceasing to exist while Google spends weeks walking into a wall. - 9 min read
Before you let the first customer in. A checklist.
A store that opens with gaps learns about them at the expense of its first customers. This list comes from two places: what Torveo's opening wizard actually checks, and what the law requires. Twenty-five points, five areas. - 8 min read
Abandoned carts. How to win them back without spam.
An abandoned cart is a shopping list with an address on it, not a lost sale. But recovery done badly is spam and a GDPR problem. Here is how the mechanism works in Torveo: what runs automatically, what needs consent, and how to check whether it earns anything at all. - 6 min read
A second language in your shop: what actually needs translating.
The language switcher in the header looks like the whole job. It is roughly a fifth of it, and the expensive part only starts once you go live. - 7 min read
WAPRO Mag and a store without middleware. How it works.
The warehouse stays the source of truth, the store reads it straight from the database, and orders come back as ZO documents. No agent installed at your site and no third system to pay for and babysit. - 9 min read
Allegro or your own shop in 2026? Let's do the maths.
A sales commission looks harmless until you multiply it by a year. We put the real cost of selling on a marketplace next to the cost of running your own shop, and show where it stops adding up.

- GDPR consents in a store: which ones you really needcoming soon
We check every figure at the source on the day of publication, and screenshots always come from a real shop. Topics marked “coming soon” are planned but not yet written, which is why they are not links.
