A
- ACL (Access Control List)
- A list of rules that says which users or groups may read a document or record. Search results are filtered with it so people only see what they are allowed to see.
- ADR (Architecture Decision Record)
- A short, dated document that records one architecture decision together with its context, consequences and rejected alternatives.
- AI (Artificial Intelligence)
- Software that performs tasks which normally need human judgement, such as reading documents, classifying them and drafting text.
- AI-DLC (AI-Driven Development Lifecycle)
- The delivery method used to build this example. AI drafts and checks work, while people make the decisions and sign each gate.
- AP (Accounts Payable)
- The finance function that records what the company owes its suppliers and pays those bills.
- API (Application Programming Interface)
- A defined set of requests and responses that lets one software system call another.
B
- BM25 (Best Matching 25 ranking)
- A keyword-search ranking formula that scores each document by how well its words match the words in the query.
D
- DAG (Directed Acyclic Graph)
- A set of steps with dependencies that flow in one direction and never loop back. Here it runs the invoice pipeline.
E
- ERP (Enterprise Resource Planning)
- Business software that keeps finance, purchasing, inventory and other core records in one system.
G
- GL (General Ledger)
- The master record of every financial account in a company's books.
- GRN (Goods Receipt Note)

I
- ID (identifier)
- A unique reference code that identifies one record, such as a document, a vendor or a payment.
J
- JSON (JavaScript Object Notation)
- A plain-text format for structured data made of named fields and their values.
- JSON-RPC (JavaScript Object Notation Remote Procedure Call)
- A message format built on JavaScript Object Notation for calling functions on another system. The Model Context Protocol uses it for tool calls.
L
- LLM (Large Language Model)
- A neural network trained on very large amounts of text. It generates and interprets language.
M
- MCP (Model Context Protocol)
- An open standard that lets AI applications discover and call tools and data sources in one consistent way.
O
- OCR (Optical Character Recognition)
- Software that turns images of printed or scanned text into text a computer can search and process.
- OIDC (OpenID Connect)
- A sign-in standard built on OAuth 2.0 that proves who a user or a service is.
P
- PDF (Portable Document Format)
- A fixed-layout document file format, widely used for invoices and contracts.
- PII (Personally Identifiable Information)
- Data that can identify a person. It must be limited to what is needed and protected.
- PO (Purchase Order)
- A buyer's formal order to a supplier, stating the items, quantities and agreed prices.
R
- RAG (Retrieval-Augmented Generation)
- A method that first retrieves the relevant documents and then has a language model answer from that material only, with citations.
- RPC (Remote Procedure Call)
- Calling a function that runs on another machine as if it were local.
S
- SDK (Software Development Kit)
- A library of tools and code that makes a vendor's service easier to call from an application.
- SES (Service Entry Sheet)
- A record that a service was performed and accepted. It plays the role of a goods receipt for services.
- SFTP (SSH File Transfer Protocol)
- A way to transfer files securely over an encrypted Secure Shell connection.
- SHA-256 (Secure Hash Algorithm, 256-bit)
- A fingerprinting function that gives a file a fixed-length digest. Any change to the file produces a different digest.
- SLA (Service-Level Agreement)
- A committed target for how quickly or reliably a service will be delivered.
- SSH (Secure Shell)
- An encrypted protocol for logging in to, and transferring files with, a remote computer.
- SSO (Single Sign-On)
- Signing in once with a central identity provider and then reaching many systems without signing in again.
Build this for your business
This example uses a generic invoicing system, but the same pattern — orchestrated steps, governed tools, grounded knowledge and a documented lifecycle — fits most back-office processes. We can scope a pilot on your own documents and systems.
