Know what to order,
and exactly how much.
NAP turns your sales history into a defensible purchase list — vendor-ready quantities, in one report. No heavy planning suite.
Stock Forecast Report12 to order
| Product | On hand | Avg/day | XYZ | To order |
|---|---|---|---|---|

Quantities already rounded to vendor MOQ & pack multiple. Class Z flagged for manual review.
The balancing act
Too much ties up cash. Too little loses the sale.
Overstock
Capital frozen on shelves, write-offs on slow movers, warehouse space you pay for twice.
Stockout
Broken revenue, rushed orders at worse prices, customers who simply buy elsewhere.
A flat reorder rule can't tell the difference between a steady seller and an unpredictable one. NAP can.
What NAP does
Differentiator
Differentiator
A purchase list you can send to the vendor as-is
Open the report, scope it, get a per-product quantity to order — adjusted for stock on hand, what's incoming, what's outgoing and what's already on a draft PO.
Vendor MOQ & multiples
Quantities respect each vendor's minimum order and pack size, rounded up — ready to purchase.
Consolidated POs
One click groups every line of the same vendor into a single purchase order — not one PO per product.
Statistical safety stock
Buffers each product to your target service level from its real demand volatility — more for erratic items, less for steady ones.
XYZ classification
Every product graded X / Y / Z by predictability. Erratic items are flagged, never given a false-precise number.
Transparent maths
Every line explains itself, step by step — so a buyer trusts the number instead of overriding it.
Plus: replacement-product roll-up, end-of-life auto-archiving, and a slow-move report for the other side of the shelf.
Smarter than a flat percentage
The safety stock is calculated, not guessed.
Instead of padding every product by the same arbitrary %, NAP sizes the buffer from each product's own demand variability and your chosen service level.
SS = Z · σ · √LT
Z service level → 90 % · 95 % · 97.5 % · 99 %
σ std. deviation of weekly demand (zero-demand weeks counted)
LT supplier lead time
σ std. deviation of weekly demand (zero-demand weeks counted)
LT supplier lead time
How predictable is each product?
X
Stable demand
Low variability — trust the automatic buffer.
Y
Variable demand
Moderate swings — statistical safety stock applied.
Z
Erratic demand
Unpredictable — excluded from auto-buffer, flagged for a human call.
Why NAP
The forecasting brains, without the planning-suite weight
On-demand report — no permanent planning objects to maintain
Statistical safety stock & XYZ built in — not a flat percentage
Runs on standard Odoo procurement — no lock-in
Maintained by Terrabit across Odoo versions
