Demand Forecaster

Demand forecasting uses historical sales data, market trends, and seasonal patterns to predict future order volumes. Accurate forecasts help ecommerce businesses plan inventory purchases, staffing, and cash flow — avoiding both costly stockouts and expensive overstock situations.

How This Forecast Works

This tool applies a simple but effective method: it takes your average monthly sales volume, applies a linear growth rate, and adjusts for typical ecommerce seasonality. The seasonality factors reflect the common pattern of higher Q4 sales (holiday shopping) and lower Q1 volumes. For businesses with unique seasonal patterns, you can toggle seasonality off and apply your own adjustments.

Factors That Influence Demand

• Seasonality — Regular patterns tied to time of year (holidays, weather, back-to-school). The single biggest factor for most ecommerce businesses.
• Trend — Long-term growth or decline in your product category or business. Your growth rate percentage captures this.
• Promotions — Planned sales events, marketing campaigns, or product launches that create temporary demand spikes.
• External events — Market disruptions, competitor actions, supply chain issues, or economic shifts that impact buying behavior.
