Welcome to the Community, nadiaj.
I want to make sure you can sync your accounts and invoices from CRM into QuickBooks Desktop.
Our Intuit Developer Team can provide your more details about syncing transactions from CRM. I suggest posting this question as a new topic in the Intuit Developer Community so you'll get direct assistance from one of our product experts.
I'm including an article on how to correct Web Connectors errors: Troubleshoot Web Connector errors.
I'd appreciate if you can update me on how it goes. I'll be here if there's anything else you need. Have a good one.
