Incorrect Check Numbers

I can help you sort this out, @dstahl.

Let's start by accessing your QuickBooks account using a private browser or incognito browser. This way, we can isolate this unexpected printing behavior for possible a browser-related issue. You can use either of these keyboard shortcuts:

•  For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

Also, you may have transactions that were modified causing the checks to print an incorrect order. You can reset the check number sequence by enabling the Custom transaction numbers from the Sales settings.

Here's how:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Choose the Sales tab.
4. Click Sales form content, then select Custom transaction numbers.
5. Hit Save.
6. Click Done to finalize the changes. 

Once you set one check number, the system will increment the number by one when you create another check, or the rest should generally follow in order. Now, you can start printing it.

Feel free to leave a comment below if you have other printing-related questions. I'm always here to help.

Thank you for your speedy reply. I have already followed these steps to allow custom transaction numbers, still after attempting these changes within an Incognito Tab in Chrome, same issue. I have checked all accounts searching for discrepancies in check numbers and I do not see any duplicated checks or skipping in numbers. Below is my process of how I write a check as I am new to the online experience of QuickBooks.

1. Click New 

2. Check

3. Fill out Check Info (Adjusted to the correct account)

4. Unclick Print Later

5. Adjust Check # to the correct one

6. Print the Check (Print Screen shows correct check number)

7. Finish Print

8. Next check reverts to the original incorrect check #

Thanks for keeping us updated, dstahl.

I've read the previous response and I can see that all possible causes and troubleshooting steps have already been shared with you.

The Custom transaction number feature only applies to sales transactions suc as invoices and sales receipts. 

In this case, it's best to reach out to our chat or phone support teams. They can take a closer look at this to determine why an old check number keeps on showing up when creating new transactions. Here's how:

1. Click Help in the upper right-hand corner of QBO.
2. Click Talk to a human, then type in Talk to a human.
3. Select I still need a human.
4. Click Contact Us.
5. Select between Send a message or Get a callback.

The Community is always here if you need anything else.

Did you ever receive resolution of this issue? I have the same problem. 

Hello there! @Walck. Welcome to QuickBooks Community! I'd be happy to share some details about incorrect check numbers.

There are times that your browser is full of frequently-accessed page resources causing unusual behavior. You can do these troubleshooting actions to check if the issue is browser-related.

Here’s how: 
   

   1. Restart your browser. 

   2. Use other browser like Incognito.

   3. Clear your browser’s cache and browsing history.

Otherwise, you can check your settings to see if this option is on: Warn if duplicate check number is used.

You can do so by following the steps below: 
   

  1. Go to the Gear icon.

  2. Select Account and Settings.

  3. Click Advanced tab.

  4. Look for Other preferences, then hit the pencil icon.

  5. Tick the box for Warn if duplicated check number is used.

  6. Click Save, then Done.

If issue still persist after following the steps above, I would advise to reach out to our QuickBooks Online Support and have them check your account to see what’s really causing this issue.

Feel free to reach out if you have any further questions. Have a good one!

This is why using Quickbooks Online is a really stupid idea.
