  1. 1. Today Summit Supply $232 at risk
  2. 2. Nov 17 Demo Second Due Co. on track
  • Summit Supply: order by today — about $232 of sales at retail price (some SKUs at unit cost) could be missed if this order is late (up to 6 days short)
  • Demo Second Due Co.: order by Nov 17 — on track if ordered by then
Estimates use each variant's current Shopify price where set; SKUs with no price use unit cost, so they understate lost sales. An estimate, not a guaranteed loss. Mark ordered saves only today's date.

  • Demo Sent Today Co.: PO sent today; expected restock about Nov 24 (demo).
Expected restock = the date you last downloaded or emailed a PO for that supplier in Reorder Math + its lead time (measured when we have it, otherwise the one you set). Restocks are read from daily inventory snapshots. If a delivery doesn't show up in inventory, use Mark received (or Arrived on… if it came in on an earlier day). Undo removes only the newest PO, part-arrived, or received date, if it was a mis-click. Marked it late? Use Received on… to set the real date (last 14 days) so lead times stay accurate. Split shipment? Part arrived… notes the first box and keeps the PO open; lead time and on-time % count it once the rest is marked in.
Your next reorder is due (demo data)

Reorder Math saved you an estimated $1,903 in cash this trial, plus 1 likely stockout avoided. (demo data)
  • Cash not tied up (Skip next order): $531 — 2 slow SKUs left out of suggested reorders, at unit cost. An estimate of stock you didn't buy, not cash banked.
  • Cash freed from slow stock: $1,372 — Drop in slow/dead stock value since your first inventory snapshot, at today's unit cost. A change in stock value, not cash in the bank.
  • Stockouts likely avoided: 1 of 1 — At-risk POs that restocked before the predicted run-out (from your PO dates and restocks seen). Likely, not certain.
  • POs built: 6 — 4 downloads, 2 email drafts opened in your mail app this trial. First PO in 3 minutes.
Since you started on Sep 15 (60 days): an estimated $1,903 in cash, 6 POs built. At this pace, about $952 a month (a projection, not a promise).
