4. Company profile

First of all, we need your complete company profile with the most important information about your company.

This information is used to provide you with a contract offer.  


Depending on the legal form selected, you will be asked to enter information specific to that legal form.  


We then match the data you entered in the company profile with the data stored at the Federal Central Tax Office (BZSt).

5. Contract

After completing the company profile, you will be entering into a contract with us – completely digitally.

A total of three contracts are concluded. The „Platform terms of use” contain the contractual regulations for selling on the marketplace. The link "Payment services contract" leads to the contract you conclude with Hanseatic Bank to accept customer payments on our platform.


OTTO is currently taking the next step by establishing its own payment service provider in order to be able to process and control all payment activities independently. Therefore, the confirmation of a second "Payment services contract" is necessary in the course of the connection.
