Rillet is an AI-native, cloud enterprise resource planning (ERP) and general-ledger platform built for modern finance teams. It automates core accounting workflows — general ledger, accounts receivable and payable, bank reconciliation, revenue and contract management, month-end close, and financial reporting — and layers on "Aura AI" for natural-language querying and workflow automation. The Rillet Accounting API (OpenAPI 3.1, 110 operations) exposes accounts, subsidiaries, customers, vendors, products, contracts, invoices, credit memos, bills, journal entries, bank accounts/transactions, reimbursements, and financial-statement reports, with bearer/OAuth2 auth, RFC 9457 errors, idempotency, keyset pagination, signed webhooks, and an official hosted MCP server. Rillet is backed by Creandum, First Round Capital, and ICONIQ.
