Hey there, @EmeraldOffice.

Thanks for coming to the Community. I'm here to provide some insights about the character fields in your customer's information section. 

In QuickBooks Desktop, each field in your company data file has a maximum number of characters that can be entered. To learn more about these limitations, please check out this article: Character limitations for fields in QuickBooks.

I can see how this feature would be beneficial to you and your business. I will send this feedback on your behalf so our developers will be aware of how we can improve your QuickBooks Desktop experience. 

Please know that you've got me here in the Community if you have any other questions with QuickBooks. Have a good one!
