I accidentally marked an invoice as paid when it is not. How do I reverse this?

Deleting the invoice payment can be done with ease, @debbie-green.

You'll have to delete the payment linked to the invoice. Doing this will clear the invoice' paid status.

Here's how:

1. Go to Sales or Get paid & pay in the left navigation menu.
2. Select the Invoices tab.
3. Find the invoice. Click the drop-down button below the Action column and select View/Edit.
4. Click the payment made hyperlink below the PAID payment status and select the date.
5. On the Receive Payment window, click the More button at the bottom and select Delete.
6. Click Yes to confirm.

Once you got the customer's payment, you can record it right away. You can also create recurring transactions in QuickBooks Online. It allows you to save time and reduce mistakes when making any repetitive entries.

Thank you but as I told the respresentative I spoke with, I deleted and re created invoice but twice now  it just says  that a credit has been added and the invoice still says paid

I also accidentally marked 2 invoices as "Paid" and it was showing a $555 Credit, so I went back and tried to "Reverse" it and now it has a $285 credit! Help! 

I tried messaging a few minutes ago and don't see my message.  Anyways, I accidentally marked 2 invoices as "Paid" and now cannot reverse them. I tried going back and reversing and it went from them having a $555 Credit to having a $285 Credit! Help

Welcome to the Community. No worries, I’ll help you resolve this so the right credit amount of the invoice will be posted in QuickBooks Online (QBO), SmallBusinessOwner23.

QBO offers a handy process to reverse transactions easily in case unintentional actions happen. We can set your invoice back to an open status by deleting the payment you created. Just click the Payment made link and delete the payment created. I’m glad to show you the steps:

1. Go to the Sales menu, then click All Sales.
2. Locate the entry that has the payment. You can use the Filter option to narrow down the results.
3. Under the Action column, click View/Edit.
4. Tap the Payment made link (example: 1 payment made ($555.00).
5. Hit the Date hyperlink.
6. Tap More at the bottom of the Receive Payment page.
7. Choose Delete and select Yes to the prompt message. Your invoice will return to its open status after.

When you’re ready to record the payment in the program, follow the steps in this article: Record invoice payments in QBO. Then, you can make a bank deposit to match your bank feeds.

Furthermore, you can run regular invoice reports to ensure your business is always on track and prepared for success. Additionally, I'm leaving you this article if you'd be interested in personalizing your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

how about regarding vendor bill invoices ?

system suddenly mark as paid for all open bill invoices but those are not paid 

Thank you for joining this thread, Mabel.

I'd be delighted to guide you with correcting those bills and ensuring they won't be marked as paid.

Before we continue, it's important to understand that we have 2 options for dealing with this situation in QuickBooks Online. You can either delete or void the transaction.

When you void a transaction, the record remains in QuickBooks but doesn't affect your books. On the other hand, if you delete a transaction, it's completely removed from your books and won't appear in any reports or accounts.

Therefore, it's better to void the transaction to maintain the complete record. Only delete a transaction if you're certain that you don’t need a record of it.

Here's how to void the bill payment and return the bill to open status:

1. Go to the Expenses menu, then select Bills.
2. Click the Paid tab.
3. In the action column, click Show payments for the bill that should not be marked as paid, then select View details.
    
   
4. At the bottom of the Bill payment page, click More and choose Void.
5. Confirm the void by selecting Yes/Void in the prompt message. Your bill will return to its open status after it's voided.
