LandedCost records what your inventory really costs — freight, duty, insurance and handling included — and keeps the math auditable. Sync your products and orders: Connect your Shopify store to sync products, variants, inventory levels and order history (last 60 days). No customer PII is collected — only order IDs, timestamps, line items and quantities needed for demand statistics. Statistical inventory policies: Safety stock and reorder points computed from your actual demand history using the normal distribution formula (z × √(LT·σD² + D²·σLT²)). ABC classification ranks your variants by revenue share. Reorder suggestions tell you exactly how much to order, with urgency levels and full audit trails. Allocate by charge, not by guesswork: Every landed cost charge carries its own basis (per unit or per value) and splits across PO lines with largest-remainder allocation that sums back to the charge exactly. No cent is lost, and every allocation is recomputable from its recorded inputs. Partial receipts, frozen at the moment of receipt: Record deliveries in batches. Each batch freezes the exact cost known at that moment, so your books never get quietly rewritten later. Late invoices, honest corrections: When a supplier invoice or credit note arrives weeks after closing a PO, post a revision. The original charge stays untouched; an adjustment records the delta and shows, per receipt batch, the difference between the frozen cost and the corrected one. Recorded history is never backfilled. Export everything: CSV export for purchase orders, receipts, invoices and reorder suggestions — all fields match the database exactly, so you can independently recompute every number. What it deliberately does not do: No sales-based sold-vs-remaining cost split (requires read_all_orders approval), no demand forecasting beyond statistical safety stock, no automatic inventory write-back to Shopify. We would rather show you an honest number than invent precision.

• Auditable landed cost per PO: charge-level allocation (per unit / per value) with largest-remainder math that sums back exactly — every number recomputable.
• Statistical reorder points: safety stock and ROP from your real 60-day demand history, with ABC classification, urgency levels and full audit trails.
• Honest corrections: partial receipts freeze cost at the moment of receipt; late invoices post as revisions — recorded history is never backfilled.
