Measured from the PO-sent and received dates recorded in Reorder Math. Using it updates this supplier's lead time in Reorder Math only, which moves its reorder dates earlier.

Measured lead times running shorter (demo data)
  • Northwind Goods has taken about 8 days from PO to arrival (10 orders); its lead time is set to 14. Using measured 8 days holds about $2,030 less stock.

Measured from the PO-sent and received dates recorded in Reorder Math. Using it updates this supplier's lead time in Reorder Math only, which moves its reorder dates later and holds less stock on hand.

Shop defaults

Used for any supplier or SKU without its own terms. Order: SKU override → supplier terms → shop defaults → app defaults (14d lead, 7d review, no minimum safety stock).

Minimum safety stock applies shop-wide: safety stock = the larger of the statistical value (service level × demand variability) and velocity × these days.

Which order to send first

Estimated lost revenue if each order waits, at each variant's current Shopify price; SKUs with no price are valued at unit cost (lower). An estimate, not a guaranteed loss. Leaves out Atlas Textiles, Northwind Goods — PO already on the way.

  1. Summit Supply: $232 retail + cost · 2 order-now SKUs, could run out up to 6 days before a restock ordered today arrives
Supplier scorecard

Per supplier: lead time set vs seen, on-time % from POs you sent in Reorder Math, and at-risk POs that restocked before or after the predicted run-out. On-time % fills in once POs you download or email here are restocked. Built in your browser; nothing is stored.

Editing supplier lead times, MOQ and case packs is included in Standard. See plans → (14-day free trial)
