Let me share some insights with integrating Supplier Management Solution into QuickBooks Desktop.
QuickBooks currently doesn't offer direct integration for Supplier Management Solution.
The good news is there are many applications that can help do this in QuickBooks.
Please visit our Intuit Marketplace. You can search for the third-party applications that are most compatible with QuickBooks Desktop. Check out the reviews from the customers. This can help you decide the third-party app that suits your needs.
That should answer your question. If you have any concerns about QuickBooks, please leave a comment below. Have a good one.
