It depends. We once were quoted 300K/year by a SaaS company. We replied by saying that our budget is 20K. "Fair enough, we'll take that".
A lot of value in some SaaS apps is in the initial investment it took to build it, not in the cost to host a customer's assets.
If the runtime costs of a new customer are negligible, would you rather have 0K or 20K?
If dodgy pricing/sales tactics didn't work then Oracle would be bankrupt instead of a 300 billion dollar company.
