The invoice number does not show on the actual invoice document

Hi there, Andre!

This happens when the Form Numbers option is not enabled on the invoice form style that you use. I can guide you to enable it so that you'll see the number on your actual invoices.

1. Open the invoice transaction.
2. Click on Customise at the bottom and choose Edit current.
3. Click the Content bar.
4. On the previewed invoice, click top section where you see the INVOICE#.
5. Place a check mark in the Form numbers checkbox.
6. Click Done to save the changes.

Let me know if you need anything else. Have a good day!

Form numbers checked on the content tab.

The other templates show correctly.

I want to use the 'Friendly template as it is the only one to have column headings

Thanks for joining the thread, RogerM.

Aside from checking the Form numbers, we also need to make sure that you've selected the correct template. Create an invoice as usual. Click on Customise button at the bottom. Then, select your customised template. You can also follow these steps to make it default:

1. Go to Custom form styles.
2. Locate the invoice template. Click on the arrow beside the Edit.
3. Select Make default.

Let's perform these steps if what you'd like to achieve is to show the Invoice no. field when creating it. This field won't appear on the invoice page if this option isn't turned on. Though, it'll still show when previewing it since QuickBooks will automatically generate an invoice number.

1. From the Gear icon, select the Account and Settings.
2. Select the Sales tab. Click on the Sales form content section to expand it.
3. Check the Custom transaction numbers box. Then click on Save.

Also, let's check if your Adobe Reader/Acrobat is updated. It can cause errors when previewing a document if you're using an old version.  You can check this article as your guide on how to update, repair, or re-install Adobe Reader/Acrobat.

I'd suggest contacting our Customer Support Team if there are no changes. They'll be able to check the cause of it.

1. Go to Help and select Contact Us.
2. Enter "Invoice Number" as the topic. Click on Let's talk.
3. Select Start an email.

Good morning. And what setting is used to activate automatic sequencing of invoice and quotation numbers particularly if you usingprefix link ABC001?

You've come to the right place for answers, @mkalaluka. I hope you are well today.

I'll ensure you can activate the number sequence for your invoice in QuickBooks Online (QBO). This way, you can easily track them. 

First, change the settings and turn on the Custom transaction numbers feature from your Account and Settings. This way, you can control the sequence. Here's how: 

1. Go to Settings ⚙ and select Account and settings.
2. Select Sales, then select anywhere within the Sales form content section.
3. Turn on Custom transaction numbers. 
   
4. Select Save, then select Done. 

Once done, you can now manually add the invoice number. QuickBooks Online will remember the number and continue the sequence number you want.

If you would like to review the invoices you made, run the Invoice List. Pull this up by going to the Reports menu at the left pane, then type Invoice List on the search bar. 

Check this article for more information: How to change the invoice number on sales forms. 

Additionally, when you use this feature and decide to turn it off after setting up your desired invoice number, QuickBooks will begin assigning consecutive numbers to each new invoice you create.
