Inventory Forecasting & Restock Alerts

Demand forecasting models that predict when to restock, optimize FBA storage fees, and prevent costly stockouts that tank your rankings.

What I Forecast

Inventory management isn't just counting stock — it's predicting demand, timing orders, and keeping capital working. Here's what I handle.

Demand Forecasting

Predictive models based on historical sales, seasonality, and trend analysis — not simple averages.

Seasonality YoY Patterns Weighted Averages
  • Seasonal demand curve modeling
  • Year-over-year trend adjustment
  • Promotional spike forecasting

Restock Alerts

Automated alerts when stock approaches reorder point, well before you hit zero.

Reorder Points Lead Time Buffer Safety Stock
  • Dynamic reorder point calculation
  • Lead-time-aware alert triggers
  • Multi-channel stock consideration

FBA Storage Optimization

Keep FBA costs low by right-sizing inventory levels and avoiding long-term storage fees.

Storage Fees Aged Inventory IPI Score
  • Long-term storage fee avoidance
  • Aged inventory removal recommendations
  • IPI score monitoring & optimization

Multi-Channel Sync

Keep stock levels accurate and synchronized across every sales channel in real time.

Amazon eBay Walmart Website
  • Cross-channel inventory sync
  • Oversell prevention logic
  • Channel-specific buffer allocation

Safety Stock

ABC-tiered safety stock so your best sellers are always available while slow movers stay lean.

A/B/C Classification Risk Scoring Buffer Levels
  • Revenue-weighted ABC classification
  • Generous buffers for top 20% sellers
  • Lean stock on slow-moving C-items

Supplier Lead Time

Factor in real supplier lead times, variability, and shipping delays into every forecast.

Lead Time Data Variability Tracking Buffer Days
  • Supplier-specific lead time tracking
  • Delay variability analysis
  • Automated PO timing recommendations

What You Get

Demand Forecasting Models

Historical velocity analysis with seasonal adjustments to predict future demand per SKU.

Restock Alert Notifications

Automated email or Slack alerts when inventory dips below your configurable threshold.

Days-of-Supply Tracking

Know exactly how many days of inventory you have left at current sell-through rates.

FBA Storage Fee Optimization

Recommendations to minimize long-term storage fees and avoid aged inventory surcharges.

Lead Time Calculations

Factor in supplier lead times and shipping windows so you order at the right moment.

Visual Inventory Dashboards

At-a-glance dashboards showing stock levels, velocity trends, and upcoming restock dates.

Every Project Is Different

I scope every engagement individually based on your data, goals, and timeline. No cookie-cutter packages — just a solution built around what you actually need.

Data Volume

Number of SKUs, pages, or data points to process drives the scope of the project.

Delivery Format

Raw CSV, live dashboard, API integration, or automated reporting — each has different complexity.

Ongoing Support

One-time delivery versus ongoing monitoring, maintenance, and iteration on results.

How It Works

1

Analyze

Review 12-24 months of sales history, identify seasonality patterns, and classify products by velocity (ABC analysis).

2

Model

Build demand forecasting models per SKU — incorporating seasonality, trend, and promotional calendar inputs.

3

Automate

Set up automated reorder alerts with calculated safety stock and lead time buffers. Dashboard shows days-of-stock remaining per SKU.

4

Optimize

Monthly forecast accuracy reviews. Adjust models for new products, demand shifts, and supply chain changes. Reduce both stockouts and overstock over time.

Expert Insight

Safety Stock: The Insurance You Need

Safety stock = Z-score × √(Lead time) × Standard deviation of daily demand. In plain English: the more variable your demand and the longer your lead time, the more buffer you need. A product that sells 10±2 units/day with 7-day lead time needs far less safety stock than one that sells 10±8 units/day with 30-day lead time.

The Z-score controls your service level: 1.65 for 95% in-stock rate, 2.33 for 99%. Going from 95% to 99% nearly doubles your safety stock — the question is whether that extra 4% in-stock rate justifies the additional inventory cost.

Storage Cost Optimization: The Hidden Margin Killer

Amazon FBA charges per-cubic-foot monthly storage fees that jump significantly during Q4 (October–December). Long-term storage fees escalate sharply for items sitting 271–365 days. For oversized products like glass table tops, these fees can exceed the product's margin entirely. The forecast model needs to account for storage economics — sometimes it's cheaper to risk a brief stockout than to carry 6 months of slow-moving inventory through Q4.

Forecasting you own — no $500/mo SaaS.

Custom forecasting models you control. Never lose a sale to a stockout again.
