Zentria Flow's answer:
Zentria Flow is the only tool that stacks all US tariff layers in a single calculation — MFN base duty, Section 301, and IEEPA/Liberation Day (145%) — showing importers their true cost before they place an order. No other tool combines real-time tariff intelligence with AI-powered compliance auditing at this price point.
Zentria Flow's answer:
Competitors either target enterprise logistics (Flexport) or only calculate basic duty rates (Easyship, Zonos). Zentria Flow goes deeper: multi-layer US tariff stacking, AI insights, compliance document auditing, and CFO-ready reports — all accessible to SME importers from $49/month with a free tier requiring no credit card.
Zentria Flow's answer:
E-commerce importers and sourcing managers at SMEs who import goods from China, Vietnam, India, and other countries into the US, UK, and EU. Typically dealing with 1-50 shipments per month and making sourcing decisions affected by tariff changes.
Zentria Flow's answer:
Built after watching e-commerce founders get blindsided by tariff bills they never saw coming. With US-China tariffs hitting 145% in 2026, importers needed a tool that shows the true landed cost before committing to an order — not after the invoice arrives. Zentria Flow was built to solve that gap.
