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.

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.

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 is the best app for inventory forecasting I found on Shopify by far (I tested them all), but unfortunately it's extremely expensive to use. And in recent, it became so expensive that it put the app out of the question for us. I hope in the future you can drop your prices by increasing the app users and maybe charge for any extra support?
