Hi @Jibriylscott,
Stitch Labs is a recent acquisition by Square, and it is an operations management platform. You can learn more about Stitch Labs on their website. They will be building tools for Square, so you will likely see them building tools within the Seller ecosystem, not necessarily branded Stitch Labs. These tools will help with Square's inventory and order management, channel management, and fulfillment solutions.
The Square team will likely make more announcements via email and the Seller Community on enhancements in the areas mentioned above.
As Stitch Labs cease to operate after Spring 2021, you will likely see many of these changes occur before that timeframe (purely speculation).
