Hello, @summerb.

It's best to contact VendorCafé developers or support to verify if it's possible to integrate the app with QuickBooks Online. They may have possible integration options or recommended partner providers.

Additionally, I recommend posting this query on our Intuit Developer page. By reaching out to the developers on this platform, you can gain further insights into integrating VendorCafé with QuickBooks. Their expertise will enable them to provide you with the most effective solution for your integration needs.

Here's how to connect with them:

1. Visit this link: https://help.developer.intuit.com/s/.
2. Choose your QuickBooks product.
3. Click on Ask a Question.
4. Please sign in and follow the prompts appearing on the screen to continue.
    

For future reference, you can share these articles with your client to guide them with the transition:

• Move your QuickBooks Desktop file to QuickBooks Online.
• Get started and adjust settings after you sign up.

Please let me know if you have further questions about this matter or QuickBooks-related concerns. I'll do my best to assist you in finding a suitable solution, @summerb. Best wishes! 

@summerb You can use Fazeshift to connect QBO with Vendor Café to submit and track invoices. Website is: [removed] Much better than individually entering each invoice into the portal!
