Hello, mdelectricals.
I'd like to help you connect your NatWest bank. However, I'm going to need more details from you regarding the connection process.
Did you receive an error message? If so, reply below so I can give the appropriate steps to resolve it.
In the meantime, you can do the following steps to help you resolve the error message.
NatWest might be undergoing a maintenance update. This can prevent banks from connecting to QuickBooks. You'll want to wain until they're done with it.
If you've encountered an error message, you can open this article to help you resolve it: Open Banking connection errors.
Alternatively, you can download your NatWest bank transactions and upload them manually to QuickBooks.
After successfully connecting NatWest, you can start downloading your transactions and categorising them.
Do you have questions regarding your bank transactions? Please let me know and I'll help you out. You can also add other concerns in QuickBooks Online.
