How Solvimon works

What is Solvimon?

Solvimon models billing as a small set of connected primitives. Meters define how usage is measured, and events are the raw usage you send in. Products and pricing plans describe what you sell and on what terms. Customers and subscriptions link a buyer to a plan, and invoices turn each billing period into charges you can collect and reconcile.

Every primitive is available through both Desk and the REST API, across four domains: Configuration, Identity, Transaction, and Event.
