All my invoices and quotations are mixed up! Services and quotations I sent to people have been changed and mixed up on my profile. I'm the only person with this account.

Hi emmanuelazzopard, 

Thanks for posting. Can we try to use other browser and and see if it still shows the invoices and quotations mixed up? We can also look at the Audit log to check if there were manual changes made on the transactions that may cause the mix up.  You may click on the gear icon on top right > Tools > Audit Log. 

For further assistance, we'd highly suggest you contacting our QuickBooks Online Support on this link:
