Buy what will sell. Not what sold last year.

Too much stock ties up cash; too little loses the sale. Most companies split the difference with a spreadsheet and a feeling. AI demand forecasting reads your sales history, seasonality and signals, and turns them into buying decisions. This guide covers how it works, the serious platforms, and when custom wins.

What AI demand forecasting is

AI demand forecasting learns from your actual sales: per product, per location, per season, with promotions, price changes and trends factored in. It produces forward demand estimates and turns them into recommendations, what to order, when, how much safety stock, that update as reality comes in. The spreadsheet answers what happened; this answers what to do.

01

History gets connected

Sales, stock levels, lead times, promotions, from your ERP, store or spreadsheets.

02

Models learn the patterns

Seasonality, trends, cannibalisation, the lift a discount gives, per SKU rather than on average.

03

Forecasts become orders

Suggested purchase quantities and timing, respecting lead times, budgets and supplier minimums.

04

Reality feeds back in

Every week of actuals sharpens the next forecast, and exceptions get flagged for a human call.

When this solution makes sense

A good fit if

  • Cash is tied up in stock that moves slowly while winners run out
  • Ordering is one person's spreadsheet plus experience
  • Seasonality and promotions regularly surprise your purchasing
  • You manage hundreds or thousands of SKUs, possibly across locations
  • Supplier lead times force decisions weeks ahead of demand

Probably not yet if

  • You sell a handful of products with stable, obvious demand
  • Sales history is short, dirty or not recorded per product
  • Purchasing decisions are constrained by contracts, not information
  • Nobody will act on recommendations they did not make themselves

What changes

Cash released from the shelves

Stock levels sized to demand rather than fear, and the freed money works elsewhere.

Winners in stock when it matters

The products that sell stop being the products that run out mid-season.

Purchasing with reasons

Orders backed by numbers you can inspect, not arguments about whose feeling is older.

Less firefighting

Exceptions surface early, while the good options are still open.

Off the shelf or custom?

When a platform is enough

If your data lives in a mainstream ERP or store platform and your products behave like retail products, the platforms above are proven and connect fast. Buy, and spend your effort on data hygiene and adoption.

When custom wins

Custom wins when your demand has structure the platforms do not model: project-driven sales, B2B order patterns, weather or events driving your market, data spread across systems that need joining first, or forecasts that must land inside your own tools and workflows. We often build the data foundation and the last mile around a proven forecasting core.

Where Sabemos fits

We build forecasting that fits how your demand really works: your data joined and cleaned, models chosen for your patterns, and recommendations delivered inside the systems your buyers already use, in Spanish and English.

Setup and onboarding

Frequently asked questions

How accurate can forecasts get?

Depends on your demand's nature: stable staples forecast tightly, fashion and novelty do not. The honest measure is against your current method: the tools usually beat spreadsheets clearly, and by how much shows up in a backtest on your own history.

How much history do we need?

Two seasonal cycles is comfortable; one is workable with care. Less than that, and the project starts with building the data habit rather than the model.

Will it handle promotions and price changes?

The serious platforms model promotion lift explicitly, if you feed them the promotion calendar. That input discipline is a big share of the value.

Do we still need a planner?

Yes, with better work: reviewing exceptions, handling launches, negotiating with suppliers. The role shifts from calculating to deciding.
