Set up your administration (onboarding)

After signing up, Booko walks you through a few steps to set up your administration. At the top you'll always see "Step X of Y".

Steps

1. Accountant – Answer Do you have an accountant?
2. • Yes, I have an accountant: you connect your administration with your firm's code.
   • No, I do it myself: you keep your own books in Booko.
2. Code (only if you have an accountant) – Enter Your accountant's code (for example BK-7F3K-9QPW) and click Send code. See "Connect your accountant with a code".
3. Company – Search for your company under Company name or KvK number (at least 2 characters). Pick your company; Booko fills in the details from the KvK. Check them and click Save and continue.
4. • Not registered with the KvK? Choose Not registered with the KvK? Enter manually.
   • Under Additional details (optional) you can add your VAT ID, legal form and IBAN.
4. Subscription – Choose Starter or Pro (see "Plans and pricing"). If your accounting firm pays, you'll see that here.
5. Done – Click Go to my administration.

Good to know

• You can stop halfway with Sign out; next time you sign in you continue where you left off.
• If the KvK search isn't working, you can enter your details manually.
• Booko support will never ask for your IBAN, password or login codes in chat. Only enter them yourself in the app.

Still stuck?

• Seeing We couldn't load your details.? Check your internet connection and click Try again.
• Stuck on a step, or keep getting Finishing didn't work? Ask for a colleague in the chat.
