Inventory Planner by Sage

Inventory Planner does a great job of helping me to plan orders for inventory replenishment. Simple and effective in helping me avoid wasted spending on unnecessary inventory while ensure adequate stock for items that sell well, based on my own shop's analytics.

UPDATE 5/17/2017: It's hard to express just how amazing the customer support behind this app really is.

At this point, we have completely replaced Stitch Labs for inventory management with Inventory Planner, which has simplified our workflow without compromising any of the features we need to manage our inventory start to finish.

Amazing app by an amazing team. Highly recommended!

We have been using inventory planner for just over 2 years and it has been a game-changer for forecasting, getting us away from massive spreadsheets and having to run numerous reports. The forecasting tools are dynamic with built in filters for seasonal variances, and all replenishments can be tweaked on the fly; but its ability to forecast and help plan is great so you rarely need to!
Integrating with all of our systems has meant we have everything we need in one place to save time and quickly made decisions. As with other Sage products, the support from help desk and access to additonal training is great.
