Tanpin kanri Β· single-item management

The inventory system that runs itself

Per-SKU demand forecasting, automatic supplier purchase orders, delivery ETAs, and a full REST + MCP surface so your tools β€” and agents β€” can run the stockroom.

REST API MCP server OpenAPI Β· llms.txt Self-host or Cloud

Built for how stock actually moves

Inspired by 7-Eleven Japan’s tanpin-kanri discipline β€” every SKU has a hypothesis, a reorder point, and an owner.

πŸ“ˆ

Per-SKU forecasting

Demand, safety stock, EOQ, and ABC analysis recomputed on a daemon cycle β€” not a monthly spreadsheet.

🧾

Automatic purchase orders

Hits reorder point β†’ draft PO grouped by supplier. Pro can email suppliers for you, with delivery ETAs attached.

πŸ€–

API & MCP first

Record sales, raise orders, attach demand hypotheses. Idempotent POSTs. HMAC webhooks. Agents welcome.

πŸ”—

POS / Stripe sync

Point your Stripe checkout webhook at AIM β€” line items map to SKUs and stock decrements itself.

πŸ§ͺ

Demand hypotheses

Weather, events, promotions: multiply forecast for a category or SKU. Auto-orders adjust immediately.

🏠

Zero-dependency core

Pure Node, no npm install required for self-host. Cloud is multi-tenant Postgres + auth when you want us to run it.
