Why doesn't QuickBooks have a customer number field?

Thank you for adding a post here on the Community page, @hdsds19.

I'm here to share some insights about the customer information in QuickBooks Online (QBO).

If you're trying to add the customer's mobile or phone number, you can enter the details under the Phone or Mobile section from the Customer information page. 

Here's how:

1. Open your QBO account, then select Customer from Sales at the left pane.
2. Click on the customer's name to open it.
3. Select Edit beside New transaction.
4. Type in the info under Phone or Mobile, then save.

However, if you're referring to the number of the customer from your record (order from the list), you can add it beside the display name. If you want to use the display name when printing the customer's checks, mark the box beside Print on check as display name.

In case you need an additional reference when managing your customers in QBO, feel free to open this link about how to add customers, sub-customers, delete or merge customers.

Also, open read our help articles for more tips while working with QuickBooks in the future.

Hello, hdsds19.

Thanks for getting back to us! I have an idea on where you can put your customer's account number in their profile. 

You might have come across this workaround, but you can add the customer number in the Company box. This box works best since it appears together with the address and complete customer's name (without overlapping any data). Here's an example: 

You don't need to add the customer number in the Print on Check as box (or anywhere where there's already an important data). There are several fields that you can use as well. Try adding it in Other or Notes. When integrating QuickBooks with your CRM, map these fields accordingly.
