Zentria Flow vs Zonos
Zonos shows your customers duty costs at checkout. Zentria Flow shows you — the importer — the true landed cost before you place the order. Different moment, different decision, different tool.
Zonos
Best for e-commerce stores that need to show customers the full duty-inclusive price at checkout. Native Shopify/WooCommerce integration, 30+ currencies, enterprise-grade. Does not help the importer with pre-order sourcing decisions, tariff stacking, or compliance auditing.
Zentria Flow
Best for importers who need to know their true landed cost before committing to a sourcing decision. Stacks MFN + Section 301 + forced-labor tariff (12.5% for China), calculates MPF/HMF, scores FTA eligibility, audits compliance documents, and delivers CFO-ready PDF reports. Free tier, no credit card.

The Critical Difference
Checkout intelligence vs sourcing intelligence
Zonos activates when your customer is about to buy. It's a checkout widget that prevents sticker shock for the end consumer. Zentria Flow activates before you place your purchase order with a supplier in China or Vietnam.
With Chinese goods paying Section 301 plus a 12.5% forced-labor tariff in 2026, the sourcing decision is where the money is. An importer who calculates their true landed cost before committing to a China supplier — accounting for MFN + Section 301 + forced-labor stacking — can pivot to a lower-tariff origin and save tens of thousands per shipment. Zonos cannot help with that decision.
Frequently asked questions
What does Zentria Flow do that Zonos doesn't?
Zonos is a checkout duty widget — it tells your customers the duty cost at the moment of purchase. Zentria Flow is a pre-order intelligence tool — it tells the importer the true landed cost before they decide to source a product from a given country. Zentria Flow also stacks the forced-labor tariff (12.5% on Chinese goods), calculates MPF and HMF port fees, provides FTA eligibility scoring, compliance document auditing, and AI-powered HS code refinement with alternative code suggestions. None of these exist in Zonos.
Does Zonos calculate Section 301 and forced-labor tariffs?
Zonos calculates duties at checkout and includes some Section 301 rates. However it does not model the forced-labor Section 301 tariff (effective 24 July 2026) as a separate stacked layer. For China-origin goods this means Zonos may show a significantly lower total than the actual customs liability.
Can I use both Zonos and Zentria Flow?
Yes — they solve different problems. Zonos handles the customer-facing checkout experience (showing buyers the full cost before purchase). Zentria Flow handles the importer's sourcing decision (should I source this product from China vs Vietnam given current tariff exposure?). Many importers benefit from both.
Is Zentria Flow cheaper than Zonos?
Significantly. Zentria Flow starts at $49/month with a free tier of 3 calculations a day (10 with a free account). Zonos does not publish pricing — it requires a demo and is enterprise-priced. For SME importers who need tariff intelligence without checkout infrastructure, Zentria Flow is accessible at a fraction of the cost.
