> If you run an API-based business in the future: Usage-based billing is a really tricky business model for a solo developer.

Can you elaborate on this? Is it just because of the inconsistency in revenue or is there some technical challenge I haven't considered?

I'm currently developing a usage-based API SaaS as a solo developer so this in particular really piqued my curiosity.

Inconsistent revenue is one - low price charged per transaction (usually) is another issue. Couple those with small subscription numbers to start with and you can see that it can take a while, if ever, before your SaaS can pay the bills.
