A concept project that executes the entire procurement workflow—from requirements input for procurement items, exploration of supplier candidates, evidence-backed extraction of price/delivery/terms, re-investigation of missing information, weighted evaluation, risk detection, negotiation draft creation, and final human selection—all within a single workspace.
Structuring Procurement Objectives
- Input procurement item, quantity, desired price, and delivery date
- Set mandatory conditions, priority conditions, and exclusion conditions
- Adjust weighted scoring for price, delivery, conditions, and payment terms (totaling 100%)
Candidate Company and Evidence Management
- Structured data for each candidate: company name, offer, price, MOQ, delivery time, payment terms
- All information tagged with source ID, tracking official page, acquisition date/time, and page location
- Unconfirmed values are not guessed; displayed as "Cannot be confirmed"
Automatic Detection and Re-investigation of Missing Information
- Detect gaps by candidate and by item
- Re-investigate if additional sources exist; retain empty fields for unfound values
Deterministic Weighted Evaluation
- Price: comparison against lowest price
- Delivery: comparison against shortest delivery time
- Mandatory conditions: ratio of confirmed conditions
- Payment terms: scoring via fixed rule table
- Unknown values treated as 0 points, eliminating arbitrary AI judgment
Risk Detection and Negotiation Drafts
- Extract long delivery times, large MOQs, information gaps, price volatility via fixed rules
- Present negotiation points (discounts, MOQ splitting, delivery guarantees, payment terms) in unsent drafts
Final Human Confirmation
- Verify sources, risks, priority/exclusion conditions, and order separation before finalization
- Update only temporary in-browser state; no external transmission or order processing
Three cases included: PC procurement (Dell / HP / Dynabook), store supplies procurement (Monotaro / IKEA / ASKUL), and SaaS selection (LINE WORKS / Teams / Chatwork). Each case operates on snapshots of official public pages acquired on August 26, 2026.
- No external LLM calls; operates on local datasets
- Order placement, payment, contracts, and procurement email sending explicitly prohibited
- Security measures implemented: Prompt Injection countermeasures, URL validation, CSP, etc.
- Built with Next.js 16, React 19, TypeScript
