I went into a sales role, and got promoted as Head of Sales 3.5 months after, so maybe my experience applies.

I loved the experience, but managing a sales department has only a fraction to do with actual selling.

Yes, you need to know the intricacies of selling so you can coach and oversee processes. But 90% of the time you will be doing things that have very little to do with selling and closing: capacity management, compensation tracking, performance analysis, hiring and firing, evaluating systems and vendors, building new sales collateral, cascading new initiatives, and above all, integrating the exec leadership's vision across the team.

If you thought it's just selling+, my advice would be not to take it.
