De-Risking a SaaS Offer?

Bali is like a smart SaaS play in general. It's not usage-based pricing, it's more like rev share. You pay your invoice and then we'll work for another month. We'll still have a service agreement so that the expectations are perfectly clear. But that's what I'm leaning towards. Like me being able to provide what it is that I say I can provide. This is my guarantee to you. You can cancel it at any time.
