Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDuty 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.
Most Shopify dashboards show revenue, not profit. A sale can look successful while it is actually losing money once product cost, payment fees, shipping, and discounts are included. Fiducia calculates net profit for every order automatically, using product costs merchants enter and the fees and discounts already present in their store data.
