Hi there,
QuickBooks is a powerful program which allows you to streamline your business. I'd be happy to share more information about creating payroll items.
At this time, there isn't an option to set up automatic recurring payroll items for every 3 months. I know how useful it would be to have this feature and I encourage you to send this as feedback to our engineers. You can do this by clicking the Help menu and looking for Send Feedback Online. New product ideas and improvements are largely based on the great feedback we get from users like you.
Let me know if this info helps. In case you have other questions, feel free to contact our support team using this link here.
