IIF billing address field length?

I appreciate you searching for an answer to your concern, @ivordurham.

The article you've searched is for the character limitations of each field. Thus, it doesn't involve the size limit on the billing address field. Currently, there isn't an option to change or adjust the sizes of the field.

I can see that this option is beneficial to you and your company. For now, I encourage submitting feedback directly to our product engineers. They may look into this suggestion and consider adding the option in the future update. To send feedback, you can follow the steps below:

1. Open your QuickBooks Desktop company file.
2. Go to the Help menu, then select Send Feedback Online and choose Product Suggestion.
3. Enter your feedback and click Submit.

You might also want to learn about the maximum number of list entries you can make in QuickBooks Desktop. This will help you better manage your company data.

Keep in touch if you need more help importing customers and financial transactions in QuickBooks Desktop. I'm still open to your replies, @ivordurham.

In what way does the post not cover field-length limits? They sure look like field-length limits to me, even though someone at Intuit thinks they should be called "character limitations", which technically describes something else:
