Duplicate Invoice numbers

Thank you.

Okay, glad the other person figured it out, but I have not, where do I find the" Customer Transaction number" to turn that off. I really need to figure out how to stop the duplicate invoice numbers.

Thanks

Can  you tell me how and where you found to PREVENT duplicate invoice numbers from happening   

How do I prevent duplicate invoice numbers from occurring ??    I use different templates 

Even with "Custom transaction numbers" not enabled QB online still duplicates invoice numbers for many of our clients.  We have called tech support and they have no idea how to fix.  Does anyone have an answer?

Hi there, chonkyfire3000.

In QuickBooks Online, the system will automatically set the invoice number when the Custom Transaction Numbers option is turned off in the settings.

Seeing that you still have duplicate invoice numbers, we recommend contacting our Customer Care Team again. We will investigate the issue with our engineers.

Here’s how you can reach out to us:

1. Click the Help icon located in the upper right-hand corner.
2. In the Help window, click the Contact Us button located at the bottom.
3. Enter your question and click Let's talk.
4. Select Start messaging or Get a callback.

For other questions or concerns, please don't hesitate to reach out to us here. Thanks.

Is this feature with Quickbooks Self-employed as well? Thanks 

We have recently discovered that a number of our invoices have also been given duplicate invoice numbers. We are using Quickbooks Online and the Custom Transaction Numbers option is turned off and has been for over a year now.

Has there been a recent change in the backend that could be contributing to this problem?

The issue seems to have started about 3-4 months ago

Welcome aboard to the Community, @benthepi, @accretive.

Right now, the ability to add a custom transaction number is only available in QuickBooks Online. For the Self-Employed version, please know that the digits automatically increment by 1 when creating the next invoice.

I've also checked here, and we haven't received any reported cases about getting duplicate numbers. I tried replicating on my test account, and everything seems fine on my end.

Considering it started happening for about 3 - 4 months already, I have to check the data on your account. Since I'm  unable to review it without asking for sensitive information, I suggest reaching out to our QBO Customer Care Team.

One of them will need to take over the problem and perform an escalation whenever needed to get you back on track. Here's how you can reach them:

1. In your company, go the Help icon to choose Contact Us.
2. Type the issue/topic under the What can we help you with section and then hit the Let’s talk button.
3. Scroll down to select the Get a callback option and then enter your contact information.

You can reach them within this time: Monday to Friday from 6:00 AM – 6:00 PM and Saturday 6:00 AM - 2:30 PM PST.

This issue started for us  14 months ago. It happened for only 1 customer.   All Invoice Numbers have been the same for that whole time.   The poor customer suffered in silence all those months.  I feel sorry I didn't notice it before last month.   Invoice Numbers were fine before 14 months ago.   14 Months ago may have been when we enabled this as a scheduled monthly recurring transaction.   The number QBO seems to have chosen is the same number as an Invoice number for an Inactive Customer from 2006 (coincidence? - probably). 

I Deleted the latest invoice with the bad number and Used the Recurring Transaction to recreate it and it received a new Invoice Number.  I have no idea what will happen automatically next month.

Adding Duplicate Invoice Number Warning capability to QBO like the other Duplicate warnings would have caught this software problem instantly . 

So, do you mean to turn off the custom invoice option and you will be notified when you enter a customer invoice twice?  and this will work even if you override invoice numbers with custom ones?

Hi there, @jma2019.

Thanks for following the thread. 

As of now, all of our users should receive a prompt that you're using a duplicate invoice number. The prompt will look like the screenshot I've included below. 

If for any reason you're not being prompted of the duplicate invoice number, I recommend contacting our Support Team. This way,  an agent can review your account securely and investigate this matter further. 

I hope this update finds you well. Please don't hesitate to let me know if you have any questions or concerns. I'm always around to lend a hand. Take care! 

Do you mean regardless of if they have the custom invoicing turned on?

To clarify, the prompt appears only when the customized transaction number is disabled from the Settings, @jma2019. This is to notify you to prevent duplication of the invoice numbers.

You're always welcome to post more of your concerns, @jma2019. We're here to assist.  

is there a way QBO warns me from creating a duplicate bill no. for all vendors, not just the matching vendor?

Hi tmushang!

Welcome to the Community! Thank you for asking about a warning for a duplicate bill number. I'll be happy to share information about this.

The only warning of QuickBooks is for duplicate bill numbers from the same vendor. There is no warning that a certain number exists on other vendors’ bills because eventually, one vendor may provide one that has already been used by others.

On the other hand, I know you have your reasons, so the best thing we can do is to run the Transaction list by vendor report and filter the bill transactions. The export the report to Excel and sort the transactions by NUM to easily find the duplicates.

I'm just around if you need assistance with your bills. Take good care always!

Hi, what can I do when I get the duplicate invoice message as it gives me the same number again and again. No matter how many times I tried. Started qb again even restarted the computer. It just gives me the same number. Please let me know what can I do. Thanks

Hello there, @Judith26.

3. Click the Sales tab.
4. Select the edit pencil icon, then turn off the Custom transaction numbers.
5. Hit Save and then Done.
