When you are month to month (MtM), it is a series of 30 day commitments, perfect for small and non production deployments that aren't needed longterm.
Contract customers typically commit for 12-36 months. For that longer commitment, FusionAuth offers discounts and a voice in product roadmap in exchange.
If, instead, customers value flexibility, they can always pay list price with no more than a 30 day obligation.
