Restock

Chain two skills so reordering ends in the books rather than in a forgotten email: inventory-planner decides what to buy, ap-processor stages what it will cost.

The gap this closes is small and expensive. The reorder gets figured out, the PO gets drafted, the email gets sent — and then nothing is recorded anywhere, so when the bill lands six weeks later nobody can tell whether the price or the quantity was right.

Step 1 — Work out what to buy (inventory-planner)

Invoke inventory-planner.

• Goes in: sales history and stock on hand from Shopify, Square, or NetSuite, or an uploaded CSV of both.
• Comes out: 7-day and 28-day velocity per item, conservative stockout dates, a sized 60-day reorder with dollar costs, and a separate slow-mover list.

inventory-planner owns all of the math — the two velocity windows, the distortion handling, the lead-time comparison, the seasonality rule. Do not redo any of it here.

Two of its rules matter enough to name in the chain:

• Zero-velocity items are never reorder candidates. They come through as slow movers with the cash tied up in them. No sales means stop buying, not buy more.
• An out-of-stock period is not zero demand. It is suppressed demand, and treating it as zero under-orders the item forever.
