Tariff Landed Cost may help you see rising costs due to tariffs for items in inventory.
Use the Landed Cost functions, plugging in the tariff amount. Enable the Landed Cost tab, calling it TLC, to see the effect of Tariffs on your Quotes, Orders, and Invoices.
Use Update on the Items to change Landed Percentage, Update Costs by calculation, and expect new Costs of Components entered on PO's to update sold Built items, too.
