Know What to Reorder Before the Shelf Runs Empty

We build forecasting models that read your sales history, promotions, lead times and outside signals, then turn them into reorder quantities your buyers can approve in one click.

[ The problem ]

Why Spreadsheet Forecasts Keep Missing

Most teams still forecast with moving averages and gut feel. That works until seasonality, promotions or a supplier delay hits.

  • 01

    Stockouts on the items that sell

    Fast movers run out between orders, and lost sales never show up in the data you use to plan the next order.

  • 02

    Cash tied up in slow stock

    Safety stock is set once and forgotten, so slow items sit in the warehouse while fast ones run short.

  • 03

    Promotions break the plan

    A campaign doubles demand for two weeks, then the forecast treats that spike as the new normal.

  • 04

    Buyers do not trust the numbers

    When a forecast cannot explain itself, buyers override it, and the model never gets better.

[ How we build it ]

How We Build Your Forecasting System

Every engagement starts with a backtest against your current method, so you see the gain before you commit to production.

  1. 01

    Data audit

    We map sales, inventory, purchase orders, promotions and lead times, and check how much history each SKU has.

    Output: Data quality report

  2. 02

    Backtest

    Candidate models are trained on past periods and compared with your current forecast on the weeks that followed.

    Output: Accuracy and stock impact by SKU group

  3. 03

    Replenishment rules

    Forecasts are turned into reorder points and quantities using lead times, minimum order sizes and service levels you set.

    Output: Reorder recommendations

  4. 04

    Rollout and monitoring

    Recommendations land in your ERP or a buyer dashboard, with drift alerts and scheduled retraining.

    Output: Live system with monitoring

Data the Models Use

We map each source in the first weeks and only use the ones that improve the result.

  • Stock on hand and in transit
  • Purchase orders and supplier lead times
  • Promotions and price changes
  • Product attributes and hierarchy
  • Holidays, weather and local events

[ Features ]

What the System Does

Built around how buyers and planners actually work, not around a model in a notebook.

01

Multi-horizon forecasts

Daily, weekly and monthly predictions for every SKU and location, including new items with little history.

02

Outside signals

Weather, holidays, search trends and local events are added where they measurably improve accuracy.

03

Reorder recommendations

Suggested purchase orders that respect lead times, pack sizes and supplier minimums.

04

Explainable numbers

Each forecast shows the drivers behind it, so buyers can see why a number moved.

05

Anomaly alerts

When sales drift away from the forecast, the planner gets an alert before the shelf is empty.

06

Scenario planning

What-if runs for promotions, price changes and supplier delays before you commit stock.

Inventory Forecasting Questions

Still deciding? A 30-minute call usually answers the rest.

Ask Us Directly
  • A year of weekly history covers most seasonality. Items with less history are grouped with similar products, and new items borrow patterns from comparable launches.

  • Yes. We read from and write back to SAP, NetSuite, Dynamics, Shopify and custom databases, or deliver recommendations through a dashboard if you prefer.

  • Yes. The system recommends; buyers approve or adjust. Overrides are tracked so the model learns where it is weak.

  • Every project starts with a backtest that compares the new forecast with your current method on the same historical weeks, before any production work.

  • Usually weekly or monthly, triggered automatically, with an alert when accuracy drops below the level we agreed.

  • In your own cloud account by default. We work under NDA and follow ISO 27001 practices.
