Pros and Cons of the 5 Most Popular Inventory Planning Tools in 2024

Inventory planning is a critical part of modern e-commerce operations, helping merchants satisfy customer demand efficiently and maintain an edge over their competitors.

Good inventory planning enables businesses to avoid overstocking and prevent stockouts, which inevitably lead to lost sales, strained cash flow and a damaged reputation.

It helps brands adapt to seasonal fluctuations and market trends with ease – which can make all the difference in an ever-evolving e-commerce landscape.

With the right software on hand, advanced inventory planning is also the key to efficient supply chain management, helping merchants strategically manage product availability, storage and movement.

While some of the best inventory planning solutions have been a top choice for years, others are new on the scene – which can make it hard to choose the right solution for your business.

Let’s look at the five most popular inventory planning tools (according to our recent poll of 500 merchants) and help you weigh up the pros and cons of each.

1. Inventory Planner by Sage

Inventory Planner is a top-rated software for inventory planning and demand forecasting that’s particularly popular with larger and fast-growing e-commerce merchants and enterprises.

Inventory Planner enables merchants to simplify or automate a number of tedious, time-consuming inventory planning tasks, freeing up tons of time for more important things and dramatically boosting productivity across your team.

Unlike many other tools, Inventory Planner also offers advanced open-to-buy functionality, which is especially useful for large or fast-growing businesses, as well as seasonal and trend-based merchants and those with long lead times (such as fashion brands).

Open-to-buy planning, also known as OTB planning, supply planning and merchandising planning, allows you to forecast how much you are going to sell and how much money you need to put aside to invest in goods.
