Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBoxfit takes the guesswork out of packing. For every order, it picks the box or mailer that fits from your catalog, splits oversized orders across boxes, and writes the total package weight to the order, so your team buys a shipping label in one step.
Cartonizer turns Shopify orders into clear packing plans. It uses product dimensions, weights, carton sizes, and packing rules to determine which cartons to use and what goes in each one. Component bundles can be expanded into physical products and packed together, while sealed supplier cartons remain intact. Configure your products and cartons once, then calculate the packing plan for each order.
- Estimates a lower-cost packaging option using billable weight
- Calculates the full package weight, box included, for accurate labels
- Splits orders too big for one box across multiple packages
- Shows the chosen box and weight on the order page and packing slip
- Calculate the cartons needed for each order
- Pack component bundles alongside other products
- Keep sealed supplier cartons intact during packing
- Apply weight, quantity, and upright packing constraints

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
