I am trying to link my monzo business account but it won't let me even though I accept it on my monzo quick books is not recognised it

I want to ensure you can connect your Monzo Business account, @wigglewagsdogwal.

Beforehand, may I ask whether you have received any error messages? This way, I'll be able to provide the appropriate amount of resolution to get this fixed.

In the meantime, let's reauthorise the connection of your Monzo Business account in QuickBooks Online (QBO) by disconnecting and reconnecting the account to online banking. For more details about the process, see this article: How to reauthorise your bank connection in QuickBooks Online.

Once your transactions are in, you can now match and categorise them. You can also do your regular reconciliation. 

Additionally, to know more about how Online Banking works in QBO, see the below articles: 

• Online Banking guide for QuickBooks Online
• Open Banking FAQs

The above links contain each step of the banking process and solve some problems.

Let me know how this goes, @wigglewagsdogwal. I'll be sure to get back to you. Have a great day.
