Demand forecasting and inventory planning

See demand coming before it arrives.

Predicstox forecasts demand for every item in every store or warehouse, tells you what to reorder and when, warns you before stock runs out, and finds the stock that isn't moving.

Who looks through it

Built for teams who pay for every empty shelf and every unsold carton.

Stockouts lose the sale today. Dead stock locks up cash for months. Predicstox works on both ends of the same problem, item by item and location by location.

  • Retail chains

    Twenty stores, one buying team. Bestsellers run out in one branch while the same item gathers dust in another.

  • Distributors

    Thousands of SKUs, long vendor lead times and retailers who expect every order filled in full.

  • D2C brands

    A campaign takes off, the hero product sells out, and the next production batch is six weeks away.

  • Manufacturers

    Raw material buying depends on finished-goods demand that sales teams can only guess at.

How to read the sky

Every product is a star. Its brightness is how much it sells.

Lines between stars join products that sell together. A soft blue band reaches from each star into the next eight weeks: that is its forecast. Two kinds of star need your attention.

Red giants

Items whose forecast will outrun stock before a new order can land. They turn red days in advance, with a reorder or transfer already drafted.

Stockout Alerts

Dimming stars

Items with far more stock than demand. They fade on the chart, and come with a transfer to a store that needs them or a markdown that clears them.

A forecast for every item, in every store, every week.

Predicstox reads your sales history, then models trend, seasonality, festivals, school calendars, weather and your own promotions to project the next 8 to 26 weeks of demand, with a confidence band you can actually plan around.

  • Item x store x week

    Forecasts are built at the level you buy and replenish, then rolled up to category, region and company totals.

  • Confidence, not false precision

    Every forecast carries a P10 to P90 range. Wide bands flag items where safety stock matters more than the point estimate.

  • Explained, factor by factor

    See how much of next week comes from trend, season, a festival or a planned discount, so buyers can challenge the number.

  • Re-learns every week

    New sales flow in, forecasts update, and accuracy is tracked against what actually sold, item by item.

View 02Reorder PlannerRA 05h 40m · Dec +07°

Know what to order, from whom, and by which day.

The Reorder Planner turns forecasts into a draft purchase plan for each vendor. It respects lead times, minimum order quantities, case packs and your open-to-buy budget, then waits for your approval.

Explore Reorder Planner
  • Order-by dates

    Each line shows the last safe day to place the order, based on the vendor's real lead time, not the promised one.

  • MOQ and case packs

    Quantities round to case packs and minimums, and the planner shows the extra cover each rounding buys you.

Gold tick = vendor lead time. Bars ending before it mean only a transfer can save the shelf.

View 03Stockout AlertsRA 09h 02m · Dec -04°

A warning days before the shelf goes empty.

Stockout Alerts compare stock on hand with the forecast and the vendor's lead time. When an item will run out before a fresh order can land, you hear about it while there is still time to act.

Explore Stockout Alerts
  • Days to stockout

    Every alert states the expected run-out date and how many sales are at risk between then and the next delivery.

  • Fastest fix first

    If another store holds spare units, the alert suggests a transfer before a rush order.

Diwali, monsoon, school reopening. Each one moves demand differently.

Seasonality Lens maps the events that shape your year and measures what each one did to every category in your own history. Regional festivals, school calendars, heat waves and rains become numbers you can plan with.

Moving festivals are aligned by event date, not calendar date.

  • Moving festivals

    Diwali, Eid, Onam and Pongal shift every year. The lens aligns history by event, not by calendar date.

  • Weather signals

    Heat, rain and cold are read per city, so umbrellas lift in Mumbai weeks before they lift in Delhi.

  • School calendars

    Term start dates by state drive bags, bottles, lunch boxes and stationery. They are built in.

  • Your own events

    Add local fairs, store anniversaries or a sale weekend. Their effect is learned from the next occurrence.

Test a discount before you print the banner.

Promo Impact simulates a promotion on your own price response. Pick a category, a depth and a window, and see the extra units, the stock you need to support it, and what happens to margin.

How it works

From a sales export to an approved purchase order.

  1. 01

    Connect your data

    Upload a sales export or schedule a nightly file from your POS, ERP or Tally. Items, stores, stock and open POs are mapped once.

  2. 02

    Backtest on your history

    Before you trust a single number, the model forecasts your past year blind and shows how close it came, item by item.

  3. 03

    Plan every week

    Forecasts refresh, alerts arrive in a morning digest, and reorder plans are drafted for each vendor.

  4. 04

    Approve and act

    Buyers review, edit and approve. Purchase orders and transfers export to the systems you already run.

Works with data from

  • Tally Prime
  • SAP Business One
  • Zoho Inventory
  • Shopify
  • Unicommerce
  • Microsoft Dynamics
  • Excel and CSV
  • REST API

Plain promises

A planning instrument, not a crystal ball.

The forecast is a calm second opinion with its working shown. Your buyers stay in charge of every rupee and dollar spent.

  • Estimates, not guarantees

    Forecasts are estimates with confidence ranges. Every number shows how sure the model is.

  • Suggests, never orders

    Predicstox never places a purchase order without your approval.

  • Inventory, not investments

    An inventory planning tool. No stock-market predictions and no investment advice.

  • Your data stays yours

    Encrypted, owned by you, and never used to train AI for other customers.

Questions

Questions from planners

How much sales history do you need?

Ideally a year, so every season has been seen at least once. Two or three years sharpen festival and weather effects. You can start with as little as 12 weeks; forecasts begin with wider confidence bands and tighten as history builds up.

Does it connect to our POS, ERP or Tally?

Yes. Most teams start with a scheduled CSV or Excel export of sales, stock and purchase orders, which works with Tally, SAP Business One, Zoho Inventory, Shopify and almost every POS. The Observatory plan adds direct ERP sync and a REST API.

How accurate are the forecasts?

It depends on the item. Fast movers in stable categories often land within 10 to 15% weekly error; slow, lumpy items are less predictable. Accuracy is measured openly as WAPE and bias for every item, and every forecast carries a P10 to P90 range so you can see how sure it is.

Can it handle new products?

Yes. A new item borrows the demand shape of similar items in the same category, price band and stores, then shifts to its own history as soon as real sales come in.

Does it place orders?

No. Predicstox suggests orders; you approve them. Approved plans export as purchase orders in CSV, Excel or a Tally-ready format, and you send them through the channel you already use.

Is this about the stock market?

No. The "stox" in Predicstox means inventory stock. It forecasts units of product on your shelves and in your warehouses. It does not predict share prices or offer investment advice.
