BoxFit Shipping is a local-first carton check for sellers who need to know whether an item fits, what the dimensional weight becomes, and what the shipment should cost before they print the label. Use it to: - compare product size against carton options before you pack - estimate dimensional weight and a quick postage line item - save carton presets and repeat packing plans locally - keep packaging math on-device for Etsy, resale, and small-batch shipping Why sellers pay for it: - one avoided bad-fit shipment or underpriced label can cover the app price - carton presets are faster than rebuilding the same packaging math each order - the app stays useful even when you only need a quick label-side check
