Welcome Jean, thanks for sharing your question on the community.
*Updated, thanks Justin for the clarification below!*
Forgive me, I don't have any experience with Quickbooks, but I believe you should be able to export your data into an IIF format from Infusionsoft. Afterward, you can import the data into Quickbooks.
From what I hear, this can become pretty time consuming to do on a regular basis, but is good to keep track of orders and such.
Perhaps you can clarify the issue you're having further and other Infusion users here can share their solution on the matter.
