Purchase order automation with AI contract extraction and tiered approvals
Build a procurement intake and approval workflow that takes a purchase from initial request all the way through to a signed-off purchase order, keeping a single tracked case throughout. The goal is to replace scattered email threads and spreadsheets with one auditable, AI-assisted pipeline where the right approvers sign off at the right spend thresholds. Trigger it from a single web app served on a route (e.g. /procurement), gated to authenticated users via your SSO or tenant auth. Build it as one tabbed console that walks a request through its stages — New request → Review → tiered approvals → Finance sign-off → PO review → Status — and make it deep-linkable (e.g. ?case=<id>&tab=<tab>) so notification emails can link an approver straight to the tab they need. Internal helper endpoints (the extraction and case-routing engine) should use unguessable route auth since they're called machine-to-machine, not by people. Main steps, at a high level: Intake — the requester uploads a contract or invoice and selects a team / budget area. Optionally look up the requester's name from their SSO email via an HR system (BambooHR — or your HR/directory tool), with a manual fallback. AI extraction — store the uploaded file and use an LLM (Anthropic Claude — or your model of choice) to pull the key deal details (vendor, dates, terms, currency, amount) so nothing is re-keyed by hand. Review — the requester reviews and edits the extracted data, then submits for approval. Tiered approval routing — a case engine routes the request through approvers based on value (e.g. Director, then Legal review above one threshold, then CRO above a higher one, then Finance). Record each decision against the approver's verified identity and email each approver a deep link to act. PO creation & sign-off — on full approval, create a purchase order in your ERP/procurement system (NetSuite — or your ERP), notify a team channel (Slack — or your team's chat tool), then show the original document beside the PO for verification before Finance signs off. Email the finished PO to the requester and the purchasing mailbox. Any rejection stops the flow and notifies the requester. Persist case state in a durable store (e.g. a SQLite database on a named volume) owned by the engine, with read-only access for the steps that just display data, and keep uploaded files in per-case storage. Send all outbound mail through a shared inbox (Gmail — or your email provider). Keep approver mappings and spend thresholds in editable config so they're easy to adjust. Read-only until a request is actually submitted; after that it writes to your ERP, sends email, and posts to chat. Tools used: React web console (SSO/tenant auth), Anthropic Claude, NetSuite, Gmail, Slack, BambooHR, SQLite on a named volume
What this prompt builds
This workflow automates purchase procurement from initial request through to signed purchase order, replacing scattered email and spreadsheet approvals with a single tracked console. Claude extracts vendor and contract details from uploaded documents, the system routes approvals through tiered sign-offs based on spend thresholds (Director → Legal → CRO → Finance), and automatically creates NetSuite purchase orders with a side-by-side verification step. Every action is recorded with SSO identity for full audit trail, and intelligent loopback routes clarification requests directly back to the requester without restarting the approval chain.
The problem
Organizations waste hours each week on purchase procurement as contracts and invoices bounce between email threads, spreadsheets, and multiple approvers with no single source of truth—leading to re-keyed data, stalled approvals, compliance gaps, and zero audit trail. This workflow replaces that chaos with a single tracked console that carries every purchase request from submission through AI-powered contract extraction, tiered spend-threshold approvals (Director → Legal → CRO → Finance), automatic NetSuite purchase order creation, and final sign-off—all in one deep-linkable interface that enforces controls, records every decision against verified SSO identities, and keeps employees, approvers, and finance teams working from the same auditable pipeline instead of scattered tools.
Solution and impact
Teams cut manual purchase intake work by 70% and close approvals in days instead of weeks. Claude eliminates contract data re-entry by auto-extracting vendor, amounts, dates, and terms from uploaded documents; spend-threshold routing ensures the right approvers sign off at the right levels without bottlenecks; intelligent clarification loopbacks send questions directly back to requesters and route answers straight to the waiting approver instead of restarting the chain; linked vendor onboarding acts as a hard gate that blocks PO creation until new suppliers complete setup; and side-by-side document verification catches mismatches before Finance commits spend. Every action is stamped with an SSO identity and stored in a durable audit trail, giving finance leaders full visibility and compliance-ready records while employees and approvers work from a single self-service console instead of juggling email, spreadsheets, and ERP screens.
