Fill mean, spread and lead time to see safety stock and the reorder point.
Economic order quantity (needs costs)
Fill all three to see the EOQ.
Nothing to paste? — a pet-supply planner's twelve weeks across four SKUs: a stable A item, a steady climber under a 480-unit MOQ, a lumpy aquarium heater, and an elk chew with a BOGO spike — plus a lead-time change and a promo three weeks out. Or , rendered from a saved reply with no run and no charge.
Paste the history
Per-item series lines plus the scenario: lead times, MOQs, promotions, targets. The series scanner sizes each item up free in your browser — mean, spread, volatility class, trend. No sign-in needed for that.
Say what you need
Full plan, forecast review, safety stock & reorder, promotion planning, or a new-item launch — plus any notes. A serious risk is reported whatever the task; the task sets where the depth goes.
Act on the plan
A pattern read per item, a method that fits it, safety stock and reorder points with the z, the lead time and the target written down, order quantities that respect the MOQ — and the risks, actions and open questions. Copy it, or download as markdown.
Does Demand Desk check the safety-stock arithmetic, or do I have to?
It checks it. The plan is required to state each safety stock as z x sd x sqrt(lead time) and each reorder point as mean x lead time + safety stock, in backticks. Your browser re-runs every one of those expressions and marks the row as checking out, or flags it when no figure in the cell matches what the formula evaluates to. It is a check of the plan's own stated arithmetic against its own stated numbers — it cannot confirm the inputs were read correctly out of your paste.
What happens if my lead time changes after I get the plan?
Use the recompute control under the parameter tables. Because each row states its z, its standard deviation and its lead time, the browser re-derives every safety stock and reorder point at a new lead time or service level locally. It is free, it is instant, and it does not need a second run.
Does anything leave my browser before I sign in?
No. The series scanner and the safety-stock calculator are ordinary arithmetic running on this page — they need no sign-in and send nothing anywhere. Only building the plan itself calls the model, and that is the only step that costs credits.
What does the plan do when my paste is missing something?
It says so rather than assuming. A field it cannot compute reads not computable and the missing input is listed under Open questions, and the coverage tag at the top drops to Partial - gaps noted or Not enough to plan. It is instructed never to fill a missing lead time or service target with an industry default.
How do I get the numbers into my spreadsheet?
Copy the parameter tables as CSV, or download them as a .csv file. Both carry the item, safety stock, reorder point, order quantity and the browser's arithmetic verdict for each row. The whole plan can also be copied or downloaded as markdown.
