Hello there, @userkavit-patel. Welcome to the Community.
Currently, there isn't an option to integrate Revolut Business with QuickBooks Online (QBO) and pull through attachments and receipts. You can connect Revolut bank to Quickbooks however you would have to manually upload receipts and attachments into Quickbooks.
You can visit the QuickBooks Apps page. It contains the complete list of third-party applications that connects with the QBO system. Then, to get the latest program updates, news, and features, you can visit our blog: The QuickBooks Blog.
In the meantime, I'm also adding this article to further guide you in managing the growth of your business using QBO: QuickBooks Help Articles. It includes topics about connecting products/apps, banking, and expenses, to name a few. You can click the + More topics button to view other selections.
Let me know if you have other concerns about integrating third-party applications and managing your transactions in QBO. I'm just around to help. Take care always.
