EUIPO: what it is and how to register an EU trade mark (2026)

Registering a trade mark with the EUIPO protects your brand in all 27 EU member states with a single application, for 10 years and with the option of renewing it indefinitely. An online application in one class costs €850, and once the application has been examined and published, anyone with an earlier right has 3 months to file an opposition. A business based in the EU can file a trade mark itself, without a representative, and an EUIPO application number opens the way to enrolling your brand in Amazon Brand Registry.

Allegro

Allegro ADS – A Guide to Advertising on Allegro in 2026

Sales forecasting for e-commerce: a step-by-step guide to doing it right

Sales forecasting is the process used to predict sales over the coming weeks or months, allowing you to align your inventory, advertising spend, and cash flow accordingly.

Amazon

What is Amazon’s invoice defect rate (IDR) and how does it work?

Selling on Amazon is about much more than just fighting for rankings and optimising ad spend; it is fundamentally about meeting strict performance standards.

Amazon CTR – how to measure it and improve your listing Click-Through Rate

CTR (Click-Through Rate) on Amazon is one of the most critical metrics directly driving your sales. It is the ratio of clicks to the number of times your listing appears in the search results. In practice, it tells you how many customers saw your product alongside the competition and decided to click through to the details. A high CTR sends a strong signal to the algorithm that your offer is appealing and deserves a higher ranking.

Allegro

Allegro commission refund: how to apply, automatic refunds and appeals

You can get an Allegro commission refund, which Allegro calls a transaction rebate, when a sale falls through: the buyer does not pay, cancels the purchase, sends the goods back or does not collect the parcel. You apply in Sales Center, in the “Orders” tab, no later than 45 days after the transaction is concluded, and in many situations Allegro refunds the commission on its own, without an application. If you are refused, you can appeal using a separate form, but only once the buyer has been refunded through Allegro.
