Inventory ForecastingSolutions
Know what to reorder, how much and when, with safety stock set from your real lead times and demand variability.
Inventory Forecasting Solutions: what the work involves
Inventory mistakes cost in both directions. Reorder too late and a best seller is out for two weeks; reorder too early and warehouse space and cash are locked in slow items. Reorder points set years ago in a spreadsheet no longer match current supplier delays, and nobody has time to review thousands of SKUs one at a time.
Where demand forecasting predicts sales, this work turns forecasts into purchasing decisions. We combine demand predictions with supplier lead times, measured from your past purchase orders and receipts, including how much they vary. From these we calculate reorder points, safety stock and order quantities per SKU and location, respecting minimum order quantities, shelf life and budget limits. Items are classified, for example by value and variability, so attention goes to those that matter most. The tool produces a daily or weekly purchase suggestion list and a list of at-risk items. Buyers accept, change or reject each line, and the system learns from those choices.
Core features
Measured supplier lead times
Actual delivery delays from your purchase history set the buffers, not the optimistic dates on quotations.
Reorder point and safety stock
Each item gets a reorder level reflecting its demand pattern, variability and the service level you choose.
Order quantity suggestions
Suggested quantities respect minimum order sizes, pack sizes, budget caps and shelf life limits.
Stock-out and overstock alerts
Items likely to run out or sit unsold are listed with days of cover and the reason.
Multi-location balancing
Surplus in one branch can be proposed as a transfer to another before a new order is placed.
Buyer feedback loop
Accepted and edited suggestions are recorded, showing where the logic and the buyer's judgement disagree.
What we get right before launch
Dirty stock records
Forecasts built on wrong on-hand counts mislead. We audit the data first, flag impossible values, and suggest cycle counting where records look unreliable.
Service level trade-off
Higher availability needs more stock and cash. We make that trade-off explicit, so owners choose a target by item class instead of getting one blanket rule.
Black-box distrust
Buyers ignore suggestions they cannot understand. Each line shows demand, lead time and cover assumptions, and buyers can override with a reason recorded.

Common questions, answered
What is the difference from demand forecasting?
Demand forecasting predicts sales. Inventory forecasting converts that into what to buy and keep, adding lead times, order rules and stock records. Most projects include both, sharing the same data.
Can it connect to our ERP or POS?
Usually, through APIs, database access or scheduled exports. Older systems may need an export file, which still works well for daily or weekly planning, and we confirm the route during scoping.
What about new or seasonal items?
With little history, we borrow patterns from similar items and mark suggestions as low-confidence. Buyers keep control, and the system tightens as sales data accumulates.
Does it place orders automatically?
Not by default. It produces suggestions for a buyer to approve. Automatic ordering can be enabled for low-value, stable items once suggestions have proven reliable over time.
