Does anyone know if there is support for Sainsbury’s Bank. I have a credit with them but can’t find them when going through add new account?

Welcome to the Community, Gavwatts.

Let's make sure you're able to get your bank information into QuickBooks Online. If you're trying to add you're bank as one of the supported financial institutions, you'll have to use the Request support your bank option and asks us to add your bank. Let me guide you through the steps:

1. When entering your bank and clicking on Find, you'll get the message: Hmm, we can't find [ name of the bank you entered ] in our list of the supported bank.
2. Click on the button Request support for your bank.
3. Enter your bank's website in the field provided.
4. Select Request.

You can check this article on how to identify the correct bank for more details. 

In the meantime, you can download transactions from your account then manually import them into QuickBooks Online using our WebConnect feature.
