So basically this is Subscription/Recurring Invoice based on usage/metered billing. SaaS/Hosting provider/Electricity provider etc

Try/Check Zoho Subscriptions (I am happy customer of "Zoho Subscriptions") - They support Many features, metered billing, Payment Methods, Many Integrations etc. Without taking much data (except what is needed minimal). And very good tech as well as non-tech customer support! And they charge reasonably fixed, transparent and predictive price.

I understand need and pain point and multiple players can exist, Key is to have transparent pricing. (You can always have custom plan/discount/ change in pricing in future etc for future customer).

Also who is your target customer? Tech company may likely implement their own billing software or use existing proven players.

I think (Happy to be wrong!) - 1. Trying to find Non-Core-Tech/Offline subscriptions service and what are their pain points? 2. Why only usage based billing?

I know there are very less tools/software for SaaS/recurring/Subscriptions based billing (Zoho, Chargebee, Recurly, Shopify few of them) so wish you good luck.

Hey it's Matt here. So there is some research done by others showing that usage-based model has doubled its adoption in the past four years, and the acceleration has not slowed by even by a bit. Data points to the fact that it will become the mainstream five years down the road. Our personal experience speaks to the same observation. That's why we aim to solve the next gen challenge. :-)

Subscription billing is a solved problem, admittedly. Many existing software is doing a decent job, marginal improvement is needed. However, those old models are very different from usage-based model, because imagine what's the volume of change for a customer's subscription? It's probably at most once a month. But for usage-based model, the volume of events would be at a level of easily 10K per second. These are not the same kind of world. Other challenges include the underlying infra to support usage-based model, flexibility for pricing, integration with usage-based reporting of cloud marketplaces, etc.. all of those things are net new, and necessary for next gen SaaS model.
