Inventory Forecasting

StockWise uses your historical sales data to predict future demand, helping you make informed inventory decisions.

How Forecasting Works

Data Collection

StockWise analyzes your order history to understand sales patterns:

  • Daily sales volumes
  • Weekly patterns
  • Seasonal trends
  • Growth or decline trends

Prediction Generation

Using statistical methods, StockWise generates forecasts for each product variant:

  • Short-term predictions (7-14 days): Higher accuracy
  • Medium-term predictions (15-30 days): Good accuracy
  • Long-term trends: Directional guidance

Continuous Learning

Forecasts are updated daily as new sales data becomes available, improving accuracy over time.

Viewing Forecasts

Dashboard View

The main dashboard shows forecast-derived metrics:

  • Days remaining (based on predicted consumption)
  • Reorder point (incorporates forecast data)
  • Inventory status

Variant Detail View

The forecast chart displays:

  • Blue solid line: Actual historical sales
  • Green dashed line: Predicted future sales

Compare predicted vs. actual to gauge forecast reliability.

Forecast Accuracy

What Affects Accuracy

FactorImpact on Accuracy
Data history lengthMore history = better accuracy
Sales consistencyStable patterns = higher accuracy
Recent changesPromotions/events can skew forecasts
SeasonalitySeasonal products need more data

Minimum Data Requirements

  • 14 days: Minimum for basic forecasts
  • 30 days: Recommended for reliable forecasts
  • 90+ days: Ideal for capturing patterns

Interpreting Confidence

Products with:

  • Consistent sales: Higher confidence predictions
  • Variable sales: Lower confidence, wider ranges
  • New products: Limited confidence until data builds

Factors Not Captured

StockWise forecasts based on historical patterns. It doesn't automatically account for:

  • Planned promotions
  • Marketing campaigns
  • Supply chain disruptions
  • Economic changes
  • Competitor actions

Consider these factors when reviewing recommendations.

Using Forecasts Effectively

Daily Operations

  • Use "Days Remaining" for immediate decisions
  • Check "Order Now" alerts daily
  • Review critical items (A-class) frequently

Weekly Planning

  • Review forecast vs. actual comparisons
  • Identify products with declining accuracy
  • Adjust safety stock for variable products

Monthly Strategy

  • Analyze trends across product categories
  • Plan for upcoming seasonal changes
  • Review and adjust threshold settings

When Forecasts May Be Less Reliable

New Products

Products with less than 30 days of history will have limited forecast accuracy. Monitor closely and maintain higher safety stock.

Seasonal Products

During season transitions, forecasts may lag behind actual demand changes. Manually adjust expectations.

After Major Changes

Significant events (viral product, major promotion, supply issue) can skew forecasts temporarily. They will normalize as new data accumulates.

Tips for Better Forecasts

  1. Maintain data quality: Ensure Shopify inventory is accurate
  2. Be patient: Accuracy improves over time
  3. Combine with judgment: Use forecasts as input, not gospel
  4. Adjust for known events: Plan for promotions manually
