70–80% forecast accuracy at SKU level (3–6 months)

VOIDS is demand forecasting software for e-commerce: predict sales by SKU, channel, and country and turn forecasts into purchasing decisions.

Forecasting, purchasing, and PO management in one system

Sales, stock, campaigns, product lifecycle, and seasonal patterns are brought together.

Guided onboarding instead of an enterprise implementation project

VOIDS connects to your existing commerce stack, maps the operating rules that shape purchasing, and supports the team through go-live.

How does VOIDS get from forecast to purchase decision?

What makes good demand forecasting software?

Good demand forecasting software does more than predict sales. It makes forecasts operational: which quantity should be reordered, which product is a revenue risk, and which campaign changes demand? For e-commerce brands, forecasting becomes valuable when purchasing and marketing work from the same demand plan.

  • According to VOIDS customer data (2026), forecast accuracy averages 70–80% at SKU level over 3–6 months.
  • More than 250 e-commerce operators trust VOIDS with over €2 billion in annual net revenue for forecasting.
  • According to the HYROX case study, specialized event demand forecasting cut out-of-stocks in half — across 2,000 SKUs in 30+ markets.

“Our problem was never demand, it was that our best-selling collars were always out of stock exactly when orders came in. Since VOIDS, we manage procurement down to the SKU. Warehouse costs dropped 35%, not a single stockout since.”

How does a forecast become a purchase order?

01

Combine demand signals

Sales, stock, campaigns, product lifecycle, and seasonal patterns are brought together.

02

Validate the forecast

VOIDS detects distortions from stockouts, promotions, and outliers and makes forecasts explainable.

03

Trigger replenishment

Forecasts become purchase recommendations, priorities, and cash-flow impact for purchasing teams.

When VOIDS is the right demand forecasting software

Spreadsheet forecasts get too slow

If forecasts are copied, adjusted, and corrected by gut feel every week, there is no shared planning logic.

Campaigns distort demand

VOIDS includes launches, marketing peaks, and historical stockouts so forecasts are not just extrapolated history.

Forecasts must drive purchasing

The system delivers not only forecasts but concrete reorder priorities and PO decisions.

How is VOIDS different from pure forecasting tools?

Forecasting alone does not solve purchasing. VOIDS connects forecasts with inventory decisions.
