# Delos > Delos helps businesses sell unpaid invoices, recover overdue payments, receive money sooner and arrange a buyer for future invoices. Learn about the options first; prepare and confirm an enquiry only when the user wants to proceed. ## Start here - [Delos plugin for ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6ac39d3125648191a96040a67fc692ac): Install the public plugin, then start a new chat and enable Delos. - [MCP connection and full agent guide](https://www.delos.international/mcp.md): Setup, tools, approved product facts, prices, document handling and confirmation rules. - [Human setup guide](https://www.delos.international/mcp): Client instructions and copyable prompts. - MCP endpoint: https://api.delosintelligence.com/mcp (Streamable HTTP, no authentication for guidance and new enquiries). - First read-only action when exposed: get_product_guidance({}). Product resource: delos://guides/products. - The published plugin and standalone MCP can expose different tools. Use the selected connection's actual capabilities and the full guide's fallback instructions when guidance is absent. ## Website - [Factoring](https://www.delos.international/factoring): Invoice funding. - [Portfolios](https://www.delos.international/portfolio): Portfolio sale and collections. - [Thesis](https://www.delos.international/thesis): Why Delos exists. - [Privacy](https://www.delos.international/privacy-policy) - [Terms](https://www.delos.international/terms-and-conditions) ## Manual enquiries - Lien filing: Lien submissions and document uploads through MCP are temporarily unavailable. For a general lien enquiry, contact hello@delos.international. [Contact Delos for a manual enquiry](mailto:hello@delos.international). ## Submission rules Guidance needs no personal details. Confirm an enquiry summary and selected files before any submission. File transmission depends on the host; obtain permission before omitting files and use the secure upload link expected by email after processing. Do not retry an uncertain submission automatically. An enquiry requests review; it does not approve funding, secure a purchase commitment, begin recovery or file a lien. Existing-case lookup is not supported.
