About Fits In The Box
Show shoppers what else fits in their current box. They add more items, you sell more.
Fits In The Box uses a 3D packing engine to show customers exactly what else fits in their current shipment. It helps merchants build bigger orders by giving shoppers a reason to add one more item. The app installs in minutes, works with your existing products and shipping rates, and handles complex scenarios like multi-box orders and cold chain requirements automatically.
- Real-time 3D packing calculates remaining box space as shoppers browse
- Smart upsell suggestions highlight products that ship with no added weight
- Works out of the box—just enter your box sizes and shipping rates
- Multi-box logic splits large orders across boxes for accurate shipping
- Cold chain support keeps frozen and ambient items separate
