About the Fits In The Box
Fits In The Box uses a 3D packing engine to show customers what else fits in their current shipment. The app helps merchants build bigger orders by giving shoppers a clear reason to add one more item before checkout.
Real-time 3D packing calculates remaining box space as customers browse your store. Smart upsell suggestions highlight products that ship with no added weight or cost. The app works with your existing products and shipping rates right out of the box—just enter your box sizes and you're ready to go.
Multi-box logic automatically splits large orders across multiple boxes for accurate shipping costs. Cold chain support keeps frozen and ambient items separate when needed. Installation takes just minutes and handles complex shipping scenarios automatically.
Launched: March 13, 2026
