I've been using Inventory Planner for 3 years now, and have just committed to using it for another 3 more. The software is great, with a very helpful team working behind the scenes. Kate, my Customer Success Manager, is an asset to the team, and is always there to help where needed.

Lavender was a great help when I didn't understand why csvs were connected

I’ve had an excellent experience working with Inventory Planner, and I’d like to highlight the outstanding support provided by their team member, Yi Chan. He has been consistently professional, knowledgeable, and incredibly patient throughout our interactions. Chan took the time to understand our business needs in detail and guided us through every step with clarity and efficiency. His ability to...

We've been using Inventory Planner for over a year now, and it’s become an essential part of how we manage our purchasing and inventory across multiple sales channels. The platform gives us clear visibility into what to reorder, when to reorder, and how much to buy; all based on accurate forecasting and real-time sales data. Highly recommend Inventory Planner to any growing e-commerce business th...

We just started using Inventory Planner and are learning the ins and outs of the product. The support team is amazing and are very clear in answering any questions or concerns that we have. Jansen, Hector, Ade and Lavender have been extremely helpful and are very knowledgable about the software program. We know Inventory Planner is going to be a tremendous help in analyzing our inventory. Thank y...

Inventory-planner has simplified the complexities of our forecasting and production planning, making it easier to wrangle the many moving parts of our operation. The platform is intuitive, flexible and fast, allowing us to customize and streamline our processes. Most importantly, the team is exceptionally responsive, always ready to assist and provide support when needed.

After investing over two months and significant effort in implementing Inventory Planner by Sage, I strongly advise against this product and the company behind it. Despite paying more than $2,000 for professional implementation services, we were largely abandoned to navigate the process independently. Support responses were excruciatingly slow—often taking a month or more, particularly after we r...

— Racing Sport Concepts

Terrible, terrible experience. Something broke with the connection at the end of September 2025 and it has basically rendered IP useless to us. The data is not syncing and we are not able to use it even though we JUST paid for an entire year ($4k). Customer service is slow to respond and we're now demanding a full refund after 21+ days of "attempting to resolve this with our engineers." Even the...

— Morning Lavender

I had a very bad experience with their customer service. I needed help reinstalling the app and was ready to pay for the monthly subscription, but I was told that my company was too small for their service. They explained that they had changed their “business model” and are now focusing only on much larger companies. I was advised to contact them again once I reach more than 1 million dollars in a...

Stuck Paying for a Product We Can’t Use We’ve been with Inventory Planner since before Sage acquired them—back when the platform was lean, reliable, and backed by great customer support. After the acquisition, our subscription cost was increased threefold. In early 2025, after renewing our annual subscription, we transitioned to a 3PL that Inventory Planner had no integration with. Despite reach...

— Modkat

Software itself works fine and I used it for a few years. It saved me a lot of time with PO and forecasting stock levels. HOWEVER, since purchasing IP, Sage have increased the annual/semi annual fees dramatically with no signs of stopping. They will corner you in an automatically renewing contract and bleed you dry. Luckily there are a number of solid alternatives out there now. I would avoid at a...

We have used Inventory Planner for years and were big fans of the tool. It has helped us with inventory forecasting in the past. Over the last few months, we have had significant challenges with Inventory Planner API with Shopify, and our data has been intermittently been syncing in Inventory Planner. For example, our last sync was Jan 13, 2025. This syncing issue has repeatedly happened over the...

— Altenew

This app ended up being useless for us, a huge waste of time and money. Be careful what you commit to, make sure you have an out if you can't use it. We couldn't generate accurate forecasts that take into account the seasonality of our product. When set to last sales, which was originally recommended by the IP team, it dramatically over forecasted sales and reorders. The other two methods didn't...

— TA3

Inventory Planner is not robust enough for our needs and has a lot of bugs. Customer support is lacking after the initial training period. Once the initial training period is over the people who were helping resolve the issues just refer you to the standard support option. This app requires a lot of manual work to see the accurate results, and you need to be using the platform for over one year fo...
