I’d add to this, numbers every SaaS sales person should know with the resources used by their services, or roughly what the marginal cost of a new customer is.

I’d add to this, numbers every SaaS sales person should know with the resources used by their services, or roughly what the marginal cost of a new customer is. Most SaaS services have very high markup, but get a few bits of infra wrong, over promise on a few things, and use expensive AWS services, and suddenly you’re selling $500 a month of AWS services for $99 a month. This is an easy mistake to make, I’ve seen it happen with these figures, and it only takes a few wrong assumptions across the engineering and sales teams.
