Hi Janetq,
Thanks for posting your question in the Community. I'll be happy to assist you with this.
At this time, there isn't an option to manually make certain fields "required fields" in QuickBooks. I know how having this feature would make things easier on your end. I encourage you to send feedback about this to our product developers by clicking the Help Menu and looking for Send Feedback Online. Great product ideas and improvements come from users like you. If you have any other suggestions feel free to send them through.
Otherwise if you need assistance with using and customizing the sales receipt templates, I recommend checking out this helpful article from our Community. The article will share more info on customizing templates so they can look more authentic to your business. Feel free to ask questions. I'm here to help.
