Tariff margin alerts for Shopify

Last night a tariff quietly made six of your products sell at a loss.

MarginGuard watches every US and EU duty schedule and tells you, the morning a rate moves, exactly which SKUs went underwater and the price to charge to hold your margin.

Free duty tools tell your shopper what they pay. None tell you your cost just moved.

Zonos and Shopify's calculator are buyer side. COGS dashboards look backward. Nobody pings the merchant the morning a duty revision turns a winner into a loser. That blind spot is the whole product.
