Hello, mary gemmiti.
Thanks for reaching out to us here. I'd be happy to provide some information.
QuickBooks Desktop provides the ability to customize predefined roles, as outlined in this guide. However, please be advised that any changes will apply to all users with the same role. In addition, you can restrict 'vendors & payables, but that would include ALL and not any one specifically. I do understand how you would benefit from having extra customization options for the users in your books, and I encourage you to submit a suggestion to our Development Team.
Feel free to reach back out if you have any other questions.
