Register your company as a customer
Start the registration by entering your Finnish business-ID
Onninen serves technical wholesale business customers. To become an Onninen customer you need a company-specific customership. To open an account, you need a Finnish business-ID, Finnish personal bank credentials for the electronic signing of the contract, and the right to sign or authorize the company to represent the company. We use the business-ID to retrieve company information from a third party company, Bisnode, where we retrieve basic company information as well as credit and payment method index information. We use the Signom service to identify the company’s signatories. Through Signom, you can also sign the contract with a power of attorney. By submitting the completed form, you agree to the storage and handling of the data in Onninen's customer database. Read more about processing customer data. Based on the information received, we confirm the decision on the account type and the terms of the customer relationship.
