Sumtracker has been a game changer for us. I’d highly recommend Sumtracker to any Shopify store that needs reliable, advanced inventory management. Plus, their support team is incredibly responsive.
Testimonial by Rolf Middendorp, Founder of Babymaxi, a Baby & Parenting Products D2C brand in the Netherlands.
I would like to tell you why we started using Sumtracker and why we've been so happy with it. Because about six months ago, we realized that good inventory management was essential for making that happen without running into all sorts of problems like running out of inventory or double selling or losing track of what we have and so on.
So I started looking for a solution that would meet all our needs and Sumtracker came out pretty quickly on top because first of all, it's really well integrated into Shopify and it basically provides all the features that we need to just keep track of where our inventory is at any point in time.
Sumtracker allowed us to seamlessly create stock transfers from one location to the next. So it it connects to Shopify automatically. It synchronizes all the different warehouses that you configure. And then if you're sending over stock, for example, new warehouses, you can automatically keep track of where that stock is and what the latest is on that.
And then in addition, it has all the features needed to manage our supplier. So Sumtracker has been a game changer for us and it really helped us make sure that the operations are up to speed and that we don't run into problems with selling things that are no longer there.
Last thing I would really like to say that the Sumtracker team has been very responsive. Every time I file a support ticket or send a message, they've been very responsive.
They've been jumping on calls even to help me out. So overall I can only speak very highly of Sumtracker and I can definitely recommend it to all Shopify stores that are in need of inventory management beyond what is the default inside Shopify. And I think once you have different locations or different stores selling multiple things, I think pretty soon you'll realize that some tracker can really, really make a big difference.

As the business grew, Babymaxi expanded its catalog to hundreds of SKUs sourced from multiple suppliers and began working with multiple 3PL fulfillment partners. Managing inventory across these locations became increasingly complex, prompting the team to look for a more reliable inventory management solution.
The Challenge Babymaxi Faced
As Babymaxi transitioned from an in-house warehouse to multiple 3PL providers, inventory management became significantly harder:
Multi-Location Transition: Moving inventory to two different 3PL warehouses while keeping the Shopify store fully operational created tracking challenges.
Overselling Risk: Inventory distributed across multiple locations made it difficult to maintain accurate stock levels, with 5–7 overselling incidents per month.
Limited Warehouse Visibility: No centralized view of where stock was located, how much was available, or what movements were happening across locations.
Supplier Coordination: Working with dozens of suppliers and hundreds of SKUs made tracking incoming deliveries and allocating stock to correct warehouses difficult.
How Sumtracker Helped Babymaxi
Sumtracker became Babymaxi's central inventory management system:

Centralized Location Visibility: A single dashboard showing stock across all warehouses, stock movements, and product history, contributing to 99%+ inventory accuracy.
Purchase Order Management: Tracks incoming supplier deliveries and purchase orders across dozens of suppliers, ensuring products are received and allocated to the correct warehouses.
