Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMargin protection for Shopify merchants importing physical goods. Tariffs jump. Freight is volatile. Suppliers raise prices. Your dashboard still shows revenue is fine — but which SKUs are quietly losing money? Landed Cost Radar pulls your catalog, lets you enter supplier cost, freight, duty, and origin country per variant, then ranks worst offenders by inventory dollars at risk.
Duty Diligence works out the landed cost of every product after US import duty and the margin it leaves you, from the cost, HS code and country of origin already on your products. There is nothing to look up and nothing to maintain. It reads the US tariff schedule twice a day, leaves out the duties that are still listed but no longer charged and tells you before a dated change reaches your products.

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 14, 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.
