Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCostPulse scans products, variants, and recent orders to show which sales have unknown gross margin because costs are missing. Merchants can enter temporary costs for a scan, reveal negative-margin orders, and export issues to CSV for cleanup.
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.
