But if you’re poor...you’re probably also not in the market for a $100/m B2B Saas product.
If SaaS is to price its service at $100/mo, then people for whom extra $5.00/day is a big deal won't be looking at this service at all, won't be contacting the owner about implementing yet another feature, etc. To get to $500/mo revenue, SaaS would need to find 5 owners.
