Purchaser is an AI-powered RFQ (Request for Quotation) intelligence platform for capital-intensive industries such as EPC, LNG, transmission & distribution, and specialty-equipment manufacturing. It ingests unstructured vendor quotes from PDFs, emails, and spreadsheets and normalizes them into structured, defensible sourcing data so procurement teams can level bids apples-to-apples, surface deviations and gaps, and produce audit-ready award traceability. Purchaser exposes a REST API (OpenAPI 3.1) covering the full sourcing lifecycle — RFQs, vendors, conversations, quotes, files, and webhooks — with API-key auth, idempotency keys, versioned /api/v1/ endpoints, sliding-window rate limiting, and connectors for SAP S/4HANA, Oracle ERP Cloud, Microsoft Dynamics 365, Infor, and more. Based in Lexington, KY and backed by Homebrew.
