Inventory Planner by Sage

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 last quarter of 2024 into 2025.

This has disrupted our analysis and forecast planning. We believe the Inventory Planner is working on a solution on updating their API to Shopify, but its not clear to us when this will be fixed and help our team with.

We would love to keep working with Inventory Planner if they can provide a stable API with Shopify.

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 all costs and recommend you do not sign any contracts.

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 work either. Forecasting at a category level was overridden in the system.

We were unable to plan Net vs Gross sales, return rate, or discount rate
Couldn't see critical metrics by week/month to create manual plans such as % to LY, build, discount rate, AUR, AIR. Couldn't group or view by key attributes or export a list of skus and each attribute column.

The interface is generally inefficient and difficult to navigate. Simple updates create a lag when attempting to save changes.

It's possible it would work for a non seasonal business with products that all have the same attributes, especially if there are a lot of people to manage it. Just make sure you can get out of it if it doesn't work.

I have a love-hate relationship with this app. The basic functions of being able to make and send POs, and see/sync inventories and invoices is great. The forecasting is so-so, and doesn't always display the data you need to see. Integration is also a PITA if you have a complicated store with multiple warehouses, and 3rd party fulfillment...I turned the 3P warehouses off in the settings, why are you still importing their inventory and variants?

Customer service is also lacking. You CAN'T call them. There isn't a number. So you're stuck sending chat messages, waiting for a response, then playing chat tag for days. I've also gotten incorrect information, with them not knowing they had some functionality that I found by clicking around, and being misinformed about how some apps integrate.

This app does save me time, but if I had the time to find another similar app, I'd jump ship.

Jansen did a great job walking through a workflow issue of ours in real time to help resolve my issue. Not only was the explanation thorough, he's been extremely helpful following up and providing step by step directions for us to use as a resource internally.

Every time I've reached out to their support team, they are timely, courteous, and resourceful.

Just signed up for this, excited to see how it all works!

When first getting to know the platfrom, it does seem like its a lot. But, once you know what you are looking at, all of that information starts coming together.

The only issue I have had so far was a variant/product issue where variats were loading as their own product rather than under the same product. I reached out to Customer Service and Jansen was the one who responded. We must have worked on this issue for 6+ months together, along with his engineering team. They did not give up until the issue was resolved. There was always constent communication between Jansen, the engineering team, and myself during the process.

If any other issues arrise I will be going to Jansen for assistance. I have been assisted by other customer service representatives before but since Jansen has more in-depth knowledge about our Inventory Planner, that I will contact Jansen for any further issues or questions.

The main reason I'm giving 5 stars is due to the outstanding support that Jasper has provided! It's really good to have someone that cares and it's so keen to help when you come across with any issues with the App

Inventory Planner is good for stock forecasting and it's good to have a function to integration Amazon and manage the Amazon FBA PO in one app.

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 for accurate information as they can't factor stockouts from Shopify or Shiphero. One example of manual work that is needed to see accurate results is reviewing data for seasonal products vs new fasting selling items. We are a clothing brand so our default method is seasonal, but the app doesn't have the ability to use a different method for products that haven't been in our catalog for a full season without a lot of manual overrides.
