Hello there, MichaelOD.

I can see how the missing invoices cause inconvenience when dealing with your business finances. Hence, I'll ensure you can link the unapplied payments to an invoice to keep your record accurate.

In QuickBooks Online, we can utilize the audit log to keep track of the changes made within the software. It helps us review if someone edited/deleted the invoice so we can recreate it with the correct details. Also, please note that only the admin can access this feature.

Here's how:

1. Head to the Gear icon.
2. Choose Audit log, then Filter.
3. Select the appropriate User, Date, or Events filter on the Filter panel and click Apply.
4. In the History column, click on View to open the audit history.

Once you've found the missing invoice, recreate the transaction with this information. After that, you can proceed to these steps to link the payment to the invoice:

1. Go to Sales, then Customers.
2. Select the customer to locate the unapplied payment.
3. Once you've found the payment, click View/Edit.
4. Select the invoice from the Outstanding Transactions section.
5. Click Save and close.

In addition, you can review these resources to learn more about unapplied cash payments and how to deal with them:

• Unapplied cash payment income on your profit and loss

On the other hand, consider running and customizing different financial reports to gain valuable insights from your business that are essential for creating informed decisions.

In February 95% of my invoices were lost. I was on the phone Extensively with a representative who was unable to help me. No one has followed up to resolve this issue, and the same thing happened again with March invoices. I am very concerned about my financial data, given the repeated problem yet to be resolved. Going through all the steps listed above, takes the quick out of QuickBooks, and the repeated problem takes quite a bit of my confidence out of using this app.

The same thing happened to me… Described in an above reply. This happened with about a dozen invoices in February, and again, with nearly all my invoices in March! No issue resolved.

It isn't the kind of experience I'd like you to have, @Perplexed2.

Let me know if you have questions about managing invoices in QuickBooks Online. I'm always here to help. Have a great day.

This isn't complicated.  QBO has a history of losing invoices as well as creating multiples of deposits and withdrawals.  I've never had an issue maintaining a file.  I have a super micro server, full parity, RAID, running FreeBSD.  I don't lose or damage files.  It's my data.  I want my master company file so I can revert every time Intuit's latest unsolicited "feature" destroys my data set again.  Intuit has proven it cannot be entrusted as a data warehouse.  I'll bet a dollar to a donut this is a class action suit within a few years.  Intuit management has become completely disconnected from reality.

Note the "related" under my post in image.  Its not an opinion that Intuit is not a trustworthy data warehouse.

Hi 

same problem here also , customers getting duplicate emails invoices that I never created , then when you try to find that invoice number it doesn’t exist 

QB is literally junk lately , all they care is the monthly billing NOTHING ELSE 

WORTHLESS 

I recognize the inconvenience your customers are facing with duplicate emails (invoices), UG20. Let me provide some solutions that can help you effectively handle this issue.

Before we begin, you may want to ask your customers if the duplicate invoices are from a different company that utilizes QuickBooks Online (QBO). If yes, they can simply check their email to verify the transaction details.

If the email address belongs to your business, another user may be sending the sales entries. We can check the Audit Log report to see the transaction history. Make sure to log in as the admin to access the activity log.

To run the report:

1. Navigate to the Gear icon in your company and select Audit Log under Tools.
2. This action will open a page that shows the list of activities performed in your company.
3. On the Audit Log page, set the correct filter for the following: User, Date Changed, and Events. 
4. From there, look for the invoices in question and head to the User column to check who emailed the entries.
   
   

To gain more insights about this built-in tool, refer to this article: Use the audit log in QuickBooks Online.

In the event that you're still uncertain about the source of the duplicate emails, we advise visiting the Security Notices page to view the list of phishing and suspicious emails. This resource contains valuable information to maintain the security of your data.

In addition, these resources contain solutions to resolve undelivered email invitations and sales forms:

• How to view list of bounced emails with delivery errors
• Sales forms are not being received by customers or being bounced back
• Invited Users did not receive the email invitation for QuickBooks Online
