Simple Legal

SimpleLegal is an enterprise legal management (ELM) platform for corporate legal departments, providing legal spend management, e-billing, matter management, vendor management, accruals, and reporting and analytics. It helps in-house legal teams track outside counsel spend, review and approve invoices, manage matters, and report on legal operations. Founded as a venture-backed legal operations startup (backed by a16z) and now part of Onit's enterprise legal management product suite, SimpleLegal is delivered as a cloud application at app.simplelegal.com. The product exposes an authenticated REST API to customers for integration with financial and matter systems, but does not publish a public developer portal, OpenAPI description, or API reference; its only standalone public discovery surface is an RFC 9116 security.txt and a vulnerability disclosure program operated through Onit.

Simple Legal is profiled on the APIs.io network. Tagged areas include Company, Legal, Legal Operations, Legal Spend Management, and Matter Management.

Simple Legal’s developer surface includes engineering blog and 7 more developer resources.
