Hello, teresay. 

I'm here to provide some details about changing the font of your company name or change the letters to lower case in QuickBooks Desktop. 

Changing the format is super easy and beautifies your form in QBDT. This is because QuickBooks want's to ensure that you can customize each part of your program and make it presentable at your end. To change the company name fort and letters, Let's go to the Company and select My Company. Then click the pencil icon and from there modify your company name.  

Additionally, In QuickBooks Desktop, there is a maximum number of characters that can be fit in. To learn more about these limitations, please check out this article: Character limitations for fields in QuickBooks.

Reach out to me if you have additional concerns or need further assistance. It's always my pleasure to help. Have a good one and stay safe!
