order rail / supplier 3 · free workflow
Work Out Which Supplier Order Is Due First — Free
Paste the date stock is needed and the rail counts back through the ordering steps, marking the ones already behind so a late order is visible before it becomes a stockout.
What this replaces
Reorder reminders trigger on stock level and ignore the lead time entirely. This counts back from the date you actually need the stock, so a step that is already past its window is marked as such while there is still a chance to expedite.
Tool note. This runs entirely in your browser — no account, no upload, no paid API key. Google NotebookLM is named as the free source-grounded reading path for the material you paste; its published free-tier terms were checked on 2026-09-13 and can change.
The four passes
Collect the smallest useful input
The date stock is needed, the supplier, and the quoted lead time.
Let the rail count back
Each ordering step is dated with the slack remaining.
Treat a past step as urgent
An overdue step needs a call to the supplier, not a plan.
Confirm the lead time with the supplier
Quoted lead times drift; the date on the rail is only as good as the number.

Everything you paste stays in this browser tab. Nothing is uploaded, there is no account, and no request leaves the page to generate the result; clearing site data removes anything saved locally.
What breaks, and what to do
Lead time given in weeks
The rail needs calendar dates; convert it.
Multiple suppliers in one paste
Only the first date is used; run one order at a time.
Partial shipments
Nothing here models split deliveries; note them separately.
