Inventory Management and Forecasting - How to Calculate an Inventory for Shopify

In the dynamic world of e-commerce, efficient inventory management can make or break your Shopify business. Overstocking ties up valuable capital, while understocking leads to missed sales and unhappy customers. By mastering inventory forecasting and management, Shopify merchants can optimize their operations, boost profitability, and delight their customers. Let’s dive into how you can calculate inventory effectively for your Shopify store.

What is an Inventory Management?

Inventory management involves tracking and controlling your stock to ensure the right products are available at the right time. For Shopify merchants, this process is essential to meet customer demand while minimizing costs associated with overstocking or stockouts.

Key aspects of inventory management include:

Monitoring stock levels
Managing supply chain processes
Forecasting future inventory needs
Reducing excess inventory

The Role of Inventory Forecasting in Effective Management

Inventory forecasting involves predicting future sales based on historical data, trends, and market insights. Accurate forecasting helps you:

Prevent overstocking or understocking
Improve cash flow
Streamline order management
Enhance customer satisfaction

Steps to Calculate Inventory for Shopify

Determine Your Average Inventory
Average inventory gives you a clear picture of how much stock you typically hold over a given period. The formula is:
For example, if your beginning inventory for the month is $5,000 and your ending inventory is $7,000.

Calculate Your Inventory Turnover Ratio
This ratio shows how often you sell and replace inventory during a specific period. The formula is:
A higher turnover ratio indicates efficient inventory management. For instance, if your COGS is $24,000 and your average inventory is $6,000:
This means you sold and replaced your inventory four times during the period.

Analyze Demand Trends
Use Shopify’s analytics tools to identify:

Best-selling products
Seasonal trends
Slow-moving inventory

Integrating forecasting apps like ForecxtIQ can provide deeper insights into demand patterns, enabling you to plan stock replenishment effectively.

ForecxtIQ’s Demand Forecasting Dashboard is a powerful tool that takes the guesswork out of inventory management for Shopify merchants. Here’s how it can help:

Product-Level Forecasting: Analyze forecasts for specific products and variants, focusing on stock levels or revenue over chosen timeframes. The dashboard provides predictions with optional higher and lower thresholds, offering a comprehensive view of potential demand fluctuations.
Optimal Stock Level Guidance: Receive recommendations on minimum and maximum stock levels to maintain for each product, aiding in revenue optimization and preventing overstocking or stockouts.
Purchase Order Insights: Gain insights into ideal stock levels for placing purchase orders, along with suggested replenishment dates, helping to avoid revenue loss from stockouts.
Forecast Accuracy Analysis: Utilize backtracing to compare projected stock demand or revenue against actual historical data, enabling assessment of forecast accuracy and informed decision-making.
Manual Adjustments: Adjust future stock demand or sales forecasts by modifying the percentage increase applied to the forecasted value, allowing for consideration of factors affecting sales that the model may not automatically detect.

By integrating ForecxtIQ’s Demand Forecasting Dashboard into your Shopify store, you can enhance inventory management, improve demand forecasting accuracy, and make data-driven decisions to support your business’s growth.

Set Reorder Points
A reorder point ensures you replenish stock before running out. The formula is:
For example, if your average daily sales are 10 units, your supplier’s lead time is 7 days, and your safety stock is 20 units:
When inventory falls to 90 units, it’s time to reorder.

Implement Safety Stock
Safety stock acts as a buffer against unexpected demand spikes or supply chain delays. Calculate it using:
For instance, if your maximum daily usage is 15 units with a 10-day lead time, and your average daily usage is 10 units with a 7-day lead time.

Monitor Inventory KPIs
Track metrics like:

Stockout rate
Overstock rate
Inventory accuracy rate

Regularly reviewing these KPIs helps refine your inventory strategies over time.
