Kable

Kable helps developers to integrate usage-based billing, invoicing, analytics, and authentication functions to their API products. In practice that means handling plans, proration, dunning and revenue recognition for recurring revenue.

The natural audience is SaaS and subscription companies. Alongside the main category they mention Billing, Developer APIs and Payments. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Kable is based in Los Angeles, California. You can read more at kable.io.

Things worth asking about: payment processor support, tax handling, and migration help. Ask for a trial on your own data, not a canned demo.

If you have worked with Kable, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
