Let's create a user that can only access specific transactions to your account, @austin12.
You can create a new role and set it to access only your customers and vendors. From here, they can only create sales and expense transactions.
First, let's create a new custom role that can only access Sales and Expenses tab:
- Go to the Gear icon ⚙ and choose Manage Users.
- Select the Roles tab, then select Add role.

- Set this role to access the Sales and Expense and then click on Next.

- Set the role name and description.
- Click on Save once you're done.
You can now invite your new user and set the role that you've just created:
- Go back to the Manage Users page and select Add user.
- On the Add a new user page, select the role that you've created from the Custom role drop-down, then click on Next.

- Enter your new user’s name and email address, then select Save.
