Did you ever get a resolution, I had had this issue with one my regular clients who now has to pay me via Venmo, and not I am getting this problem with another client.

How do you send a payment link? I have had to send the invoices via pdf and email, but have not seen anywhere where I can add a payment link. This would be helpful for future issues.

Thank you for joining this thread, vhfpp7-.

The payment link function is only available when you have a QuickBooks Payments account. For affected users of the undeliverable invoices, we recommend contacting our QuickBooks Online (QBO) Care Team and signing up for the notification list to get email updates.

To obtain the contact information:

1. In QBO, navigate to the Help icon in the upper right to display the support window.
2. Select the Assistant tab and then enter a brief description of your concern in the Type something field.
3. Tap the Get help from a human link and type a phrase or keyword in the What can we help you with? field.
4. Press the Continue button to view the support options.
5. Pick Chat to initiate a conversation and Callback to speak with an agent.
6. Provide this number to speed up the process: INV-85796.

I've attached a few links that explain the steps for troubleshooting bounced invoices and checking the status of sales entries:

I appreciate your patience while we're working on this. Reach out to me again if you have other sales-related concerns or questions. I'm always ready to assist you further.

I have 3 invoices that are bouncing back undeliverable. I have the correct email address for each customer that I have sent invoices to multiple times in the past. I see that this problem has not been resolved since 2021. This is unacceptable customer service. We are loyal QuickBooks customers. You expect timely payments for your service, and we expect that from our customers as well, but that can't happen when we are unable to email invoices. You offer the same scripted answers for every question in Quickbooks community. It's always a waste of time.

I CONTINUE to have the same issues . Invoices are NOT sending. I expect a credit on my monthly fee due to this continued issue!!!! I can not get paid if invoices are not SENDING!!!! Fix the issue immediately it’s been going on for almost two years 

Hello there, 

We have received reports about being unable to send invoices in QuickBooks Online (QBO). Rest assured our engineers are doing their best to get you back on track as soon as possible. In the meantime, you can download the invoices as a PDF and attach them to an email outside of QuickBooks Online. Please know that if you opt for this workaround, you'll need to manually apply the payment to the invoice once you receive it from your customer. 

To receive updates once the issue is resolve, you can subscribe to this link: https://status.quickbooks.intuit.com/.

For future reference, check out this article to learn how to receive invoice payments in QuickBooks Online. 

Thank you for your patience and understanding while we look into this further. If you have any further concerns, feel free to reach back out. Have a great day.

My invoices are also showing as undeliverable. There have been no changes to any emails, both sender or receiver. Is this a known issue? When can we expect it to be fixed?

Yes! It is a known issue for a couple years now. It’s still continues to be a horrible issue that they cannot fix, and the customer service is awful! Close to changing from QuickBooks!  

Hi, @4000Hwy273, and @emedibill.

We are aware that some QuickBooks Online users are having issues sending invoices to their customers. Our engineering team is working hard to resolve the issue as soon as possible.

What we can do for now is to download the sales forms and send this manually through other resources outside QuickBooks: Download and save sales forms and statements in QuickBooks Online.

We will share an update as soon as we know more. You can also check for site updates from time to time using the following links:

https: //status.quickbooks.intuit.com/.

I appreciate your patience as we work toward a solution. 

I experience this problem periodically. Today I sent two different invoices to the same client (two different billings/projects) and to the same email DL. One worked. One reported,

Invoice undelivered

We couldn’t reach some of your customers. Double check the email address and try again. 

The email that bounced has to be knowable. It is poor programming design that that the offending email is not reported back. This is a fixable problem that has been going on for years, according to this thread.

Please fix this!

I hear you, and I understand the frustration that inconsistencies like this can cause, @MirelesJ.

There's currently a new investigation (INV-97919) about undelivered invoices. Rest assured that our product engineers are working on a fix. To be notified once the issue is resolved, I encourage contacting our Support team to add you to the list of affected users. Here's how:

1. In your QuickBooks Online (QBO) company, go to Help (?).

2. Select either of these tabs:

• Assistant tab and type Talk to a human.
• Search tab and click on Contact us to connect with a support expert.

3. Choose how you want to reach us (phone or chat).

If you have other concerns about managing invoices in QBO, let me add this link as an additional resource: Manage invoices.

Let us know if you have further updates about undelivered invoices in QBO. We'll do our best to assist. Take care.

When I send my email invoices to Outlook, it is adding a ' to each end ('email.address') which causes the email to get bounced. This started within the past 3 months and only happens when I send the batched emails, like remainders or memorized items.

What can I do to get rid of the ' ' without opening each email before sending? When I look at the email address in Send Forms, there are no ' '

I understand that you are having trouble with emailing your invoices. Let me help you troubleshoot the issue, tnpmommy.

Firstly, you can ask your customers to check their junk mail and spam folders. In case the email is still not found, you can try clearing and then re-entering your email address. 

1. Go to Settings, then select Account and settings.
2. Go to the Company section, then select Edit in Contact info.
3. Clear the Company email field and enter the desired address as is, even if it appears correct. (Note: Be sure not to use any extra characters or spaces before, within, or after the address you enter).
4. Select Save, then Done.
5. Send yourself a test transaction.
6. If you still don't receive the email, try using a different email address that has a different domain (for instance, if you were using a Gmail email address, try a Hotmail or Yahoo address instead).

In addition, you can also ask an IT expert to help you with the fix. The IT expert needs to add the QuickBooks Online (QBO) mail server host names and IP addresses to your outgoing mail servers allowlist. This is so your QuickBooks emails aren't mistakenly marked as spam. 

If you're still experiencing the same issue despite trying all troubleshooting steps, I recommend getting in touch with our QuickBooks Online Support. They will be able to provide you with more specific and in-depth assistance in resolving the issue.

Furthermore, to pinpoint the issue, could you please share a screenshot on your end or let me know if you received a specific error message while emailing your invoice? Your response would be of great help so that we can provide you with the most accurate resolution to your concern.
