# Glossary

The terms this site uses, each defined once in plain words.

## Terms

- **Client.** An organization whose waste and recycling vendor invoices Pathfinder is designed to check.
- **Vendor.** A company that provides waste or recycling services to a client and sends it invoices.
- **Property.** A place where a client receives services.
- **Expected services.** The services a client expects at each of its properties. Each delivery is designed to be compared with them.
- **Delivery.** A set of invoices sent in by a client at one time.
- **Missing invoice.** An invoice that the expected services say should have arrived, and did not.
- **Exception.** A missing or problem invoice, recorded with an owner, a reason, an age and a target for closing it.
- **Configuration.** The set-up for one client: its properties, the services expected at each, how its invoices arrive, and the scope of its reports.
- **Human view.** A page of this site as designed for people.
- **Machine view.** The same page shown as its Markdown, for people who want to see what an agent reads.
- **Twin.** The Markdown file of a page, at the page address plus `.md`.
- **Launch state.** The one setting that says whether the platform is planned or live. Every Markdown twin shows it in its front matter.
- **Planned.** Designed, and not available yet.
