Tabs Platform API
REST API for the Tabs revenue automation platform that exposes the core data model of customers, contracts, items, revenue categories, obligations, invoices, payments, and usage events. The API lets finance and engineering teams embed billing into their products, sync contract and usage data, generate invoices, and reconcile payments programmatically. An LLM-friendly index of all docs and OpenAPI endpoints is published at docs.tabsplatform.com/llms.txt.
