The guide will also show you the value of leveraging robust ecommerce platforms such as Shopify that have powerful and intuitive inventory management and control features.

Understanding Your Business Needs

I will share some inventory management practices that you need to consider to streamline the inventory management for your store.

Before we delve into the different models of inventory management, it is crucial that as an ecommerce retailer you understand your business needs.

  • Product Types: What types of products are you selling, are your products perishable, seasonal or evergreen?
  • Demand Patterns: What insights can you glean from your market research and surveys, also what are the typical trends and demand dynamics related to the products that you are selling?
  • Growth Projections: Based on your market research and growth projections in your business plan, what trajectory do you expect from your sales?

Inventory Control Versus Inventory Management

These terms and phrases can be confusing as they seem to refer to the same thing. There are however important differences between inventory control and inventory management.

Inventory Control: This refers to the means of handling and regulating inventory that one already has.

It pertains to arrangement of stock across the floor, the movement of stock from the warehouse to the shelves, also refers to what you do with the leftover stock and how products are tracked using barcodes or RFID tags.

Inventory control, also known as stock control, has got a lot to do with ensuring that you have sufficient products or merchandise to meet sales demands, make a profit and minimize inventory related costs.

In a typical brick and mortar store, there would be stockpiles of inventory kept in the store.

Inventory Control

Inventory control precisely deals with how the stock is managed across the floor, moving items from the warehouse to the shelves.

Inventory Management: Inventory Management refers to inventory demand forecasting and replenishment. It pertains to strategic aspects of planning the inventory volumes for your online store.

This also covers: what inventory system and backordering processes, bulk ordering systems the store will use.

Inventory Management Strategies

There are a few inventory management strategies to consider. Each strategy has its pros and cons.

Just-In-Time (JIT): With this strategy you minimise the having excess inventory by only ordering products when they are needed.

Safety Stock: With this approach you keep a “safety stock” as buffer inventory to mitigate the risk of stockouts.

ABC Analysis: With this strategy you prioritise products based on their demand.

Understanding these strategies helps you choose the one that aligns best with your business model, demand and financial control.

Reorder Point: Based on your sales data or sales projections, calculate the point at which you should reorder products to avoid stockouts.
