How do I connect QB to Zettle? It says I need to set up VAT codes first in QB but I’m not registered for VAT and accordingly it’s turned off. Any ideas how to sort?

It's nice to see you here, LisaW47. 

You'll need to set up Vat Codes into  QuickBooks Online before connecting to the Zettle account. I'm here to guide you with the detailed steps:

1. Go to the Gear icon. 

2. Select Account and Settings under Your Company. 

3. Go to the Advanced tab. 

4. Clik the pencil icon under Accounting. 

5. In the Default tax rate selection dropdown, select No VAT. 

Once done, connect your Zettle account to QuickBooks Online. 

1. Open your QBO account, then click on Banking at the left pane.
2. Go to the Banking page, then click on Connect account or Link account (if you have existing bank connected).
3. Search and select Zettle.
4. Input the login credentials, then follow the onscreen pop-ups to complete the process.
