Inventory Planner by Sage

It's a pricey app depending on where you're at in your growth and revenue size, but worth every penny when it comes to being able to predict inventory needs. It also may feel like an overwhelming app to learn - but again it's worth the investment of your time because of how powerful it is. The best part hands down has been the support. I've had a million questions as I've used the app - and every single time I've gotten the most helpful responses and even quick changes on the backend to make the app work exactly the way I need for my brand. Cheers and thanks to the IP team - this is definitely a 5 star app and they've been an important partner for our growing brand.
