Connect DNB to Tredco
When you connect DNB to Tredco, Tredco sends the bank two things: your user ID in DNB Bedrift (DNB's business netbank) and the company's organisation number. DNB checks that they belong together and that the user can see at least one account in that company. The access in DNB decides which accounts Tredco can read.
Connecting DNB
- Log in to DNB and choose «Nettbank bedrift/Bytt nettbank» (business netbank / switch netbank) on the right of the front page. Pick the company with the same organisation number as your company in Tredco.
- Find the user ID on the right of the front page in that business netbank. It's two letters and five digits, for example AB12345. This is the user who needs the access, and the ID you enter in Tredco.
- An administrator of the same business netbank gives that user the right Kontoinformasjon → Se (account information → view) on the account Tredco should read. This is under «Administrasjon» (Administration).
- Save, and look for DNB's confirmation that the change was saved.
- Check that the grant shows in the netbank's log of administrative changes.
- Enter the same user ID in the user ID field (Bruker-ID i nettbanken) in Tredco and tap Connect the bank.
- Approve the consent with BankID at DNB.
- Back in Tredco, Tredco checks that the account's transactions can actually be read. The account shows as connected only once that read has gone through.
If you'll pay bills from Tredco, the user also needs the right to pay from the account. Viewing the account is enough for the balance and movements.
When DNB finds no accounts
The connection then stops with a message saying DNB "found no PSD2-accessible payment accounts for this corporate user ID". Nothing is connected or changed.
- Same user, same company. Access applies to the business netbank you're in. Check that the user ID in Tredco is the one that got the access, and that you granted it in the right company.
- A new right can take a while. Inside the netbank the change applies straight away, but we've seen it take time to reach the connection itself. If the error persists, try again around 15 minutes after the grant shows in the log. That's a suggestion for when to retry, not a fixed time: DNB doesn't state one.
- Still the same error? Contact DNB or Tredco support.
Good to know
- Not every account can be connected. Tredco fetches accounts through PSD2, the rules that let the bank share account information when you consent. Not every DNB product is available that way.
- Access is per user. When several users share an account, they can have different access to it.
- DNB's bank integration is something else. It's ordered in the netbank, and you don't need it for Tredco. Tredco connects through ZTL with the consent you give with BankID.
- The company and the account access are checked separately. The first time, Tredco may ask you to verify the company with Start company verification. ZTL runs that check. A verified company doesn't mean the account access is in place.
Once the bank is connected, Tredco pulls in the balance and movements by itself. The access has to be renewed every few months, see How the business is doing. To pay bills from Tredco, read The payment queue.

The name of the right and the log of administrative changes are as we found them in DNB Bedrift in our own test in November 2026, and the time a new right takes is what we've seen, not something DNB promises.
