Once your Shopify store starts scaling up, you'll need to start using an inventory management system (IMS). While management concepts such as FIFO inventory management are often discussed when considering inventory management, you'll need the right software system to carry out the functions first.

An inventory management system is a program designed to streamline inventory functions such as tracking, stocking, and fulfillment.

Handling everything from the supplier to the customer, inventory management systems help keep things running smoothly with minimal manual input. Using these in tandem with inventory management apps will help you avoid stockouts and fulfill orders quickly.

It's best to make the transition from manual systems to an IMS before you're overloaded.

Key Features to Look for in an Inventory Management System

  • Multi-store and omnichannel support: If you have multiple Shopify stores and physical locations, you'll need an IMS that can bring them together into a unified system.
  • Metrics and forecasting: A good IMS goes beyond tracking stock by analyzing historical data, forecasting demand, and acting accordingly. IMS metrics are a rich source of data on which to build models and plan strategies.
  • Integrations: Beyond the obvious Shopify integration, an IMS should support point-of-sale (POS) systems if you have physical locations, as well as integrate with your logistics systems.
  • Complete automation: A good IMS will be able to automate inventory management in various ways, not just record simple metrics and numbers. Functions such as managing out-of-stock items, managing pre-orders, and ordering from suppliers when stock gets low will make the store manager's life a lot easier.
