group vs. individual pricing

My 6 week group coaching program price is more money per person than my 12 week 1:1 coaching price. I’m trying to encourage my clients (small businesses) to purchase 1:1 sessions for their clients before purchasing a group program. After all/most employees have been coached individually, my clients can purchase a group program for their team in which we work more on specific company goals.  Does that make sense or should group prices always be less expensive than 1:1 coaching prices?
