Hello there, Danny.

When you say random changes to your bills, do you mean there are changes made to your bill by the system? I hope you can give me more details about your issue so we can properly address your concerns. Can you send me a screenshot so we'll be able to check what is happening? 

Anyway, if you have any other concerns, let me know so we can get back to you as soon as possible. We're always here to help.

Yesterday, whilst entering a Bill for a vendor, I noticed that there were several unbilled Purchase Orders for a vendor who would normally have no unbilled Purchase Orders associated with them.

After running an audit report, QuickBooks claims I added an Expense item called PayBill on July 3 – see row 1076 of the attached audit report.

Then over 1,000 Bills & Bill Payments were edited within the next 10 minutes all between the random days of Sept 2021 & Dec 2023. Many of the items originally associated with all these bills have been removed and replaced with one random line item – PayBill.

This has not only created unbilled Purchase Orders that were previously billed but it has also changed financial reports including profit and loss reports for the random period between Sept 2021 & Dec 2023.

Clearly this is some sort of glitch but I have no idea how to fix it as QuickBooks don’t offer a restore point from a previous backup as the file is constantly saved on their servers.

Do I need to manually change over 1,000 transactions to restore my records?

I have just opened Melio to sync with Quickbooks and noticed the last sync was date stamped the same time as the audit report stated I created PayBill expense etc

Let me help you take care of this and direct you to the right support, Danny.

I just sync Melio with Quickbooks and noticed the last sync was at the exact same time Quickbooks claims I created the PayBill expense item and over the next 10 minutes immediately after that, over 1,000 bills and bill payments were edited.
