Vendor Master Change & Duplicate Risk Pack

Compare two local vendor-master CSV exports for duplicates, shared banking, unapproved bank changes, missing fields and reactivation risk.

This downloadable local package turns authorized buyer-supplied files into a fixed, reproducible review packet. It includes an installable Python CLI, a local stdio MCP adapter and a companion Agent Skill.

Outputs

result.json, vendor-change-matrix.csv, duplicate-risk.csv, bank-change-review.csv, issues.jsonl, VENDOR_MASTER_REVIEW.md and evidence-receipt.json

The core is deterministic, rejects unsafe paths and malformed inputs, never overwrites an existing packet, escapes formula-active CSV cells and binds each input and output with SHA-256. Processing stays local. No API key, login, upload, telemetry or live external action is included.

Best for

Accounts-payable teams, bookkeepers, ERP consultants and internal auditors reviewing supplier exports

Requirements

Windows 11 and Python 3.11–3.14; authorized local evidence files in the documented schemas; optional mcp==2.2.0 for the local MCP adapter.

Limitations

No ERP login, sanctions or tax validation, bank-account verification, fraud determination, vendor merge, record update, payment hold or accounting certification. Demand and sales are not guaranteed; this is a one-time local V1.
