Questions and answers

Several providers offer cross-border e-commerce solutions that calculate and/or collect duties and taxes at checkout, often under a DDP (Delivered Duty Paid) model:
- Zonos — Offers international checkout with upfront landed-cost calculations for shipping, duties, taxes, and carrier fees. It also handles tax remittance and guarantees the calculated landed cost.
- Avalara — Its AvaTax Cross-Border product calculates customs duties and import taxes in real time and supports collecting them at checkout. It can integrate through ecommerce platforms or APIs.
- FlavorCloud — Provides cross-border shipping with guaranteed duties, taxes, and fees at checkout, including prepaid DDP services.
- ESW — Provides Global Checkout plus Merchant of Record services, taking responsibility for tax, duty, and regulatory obligations while showing transparent landed costs at checkout.
- Borderfree — Provides international checkout where shoppers can be offered prices inclusive of import duties and taxes, along with international shipping and customs-clearance costs.
- Shopify — Shopify itself can calculate and collect international duties and import taxes at checkout, subject to product, carrier, destination, and DDP requirements.
The important distinction
If you're evaluating these for a business, there are roughly three models:
Model Examples What they handle Landed-cost calculation/API Avalara Calculates duties/taxes; you integrate the result into checkout Cross-border checkout + DDP Zonos, FlavorCloud Checkout, landed cost, payments/shipping workflows, and duty/tax handling Merchant of Record (MoR) ESW Provider becomes responsible for the transaction's tax/duty/regulatory obligations If your requirement is specifically “customer sees one final price at checkout, and the provider guarantees/handles any subsequent duty & tax liability”, Zonos, FlavorCloud, and ESW are particularly relevant based on their current offerings.

If you're looking at this from a merchant/platform perspective, I can also compare these providers on pricing, merchant-of-record vs. DDP, Shopify integration, countries covered, and who actually assumes the duty/tax risk.

Several prominent cross-border e-commerce solutions specialize in calculating and collecting customs duties, import taxes, and landed costs directly at the digital checkout . These platforms enable a Delivered Duty Paid (DDP) model, ensuring transparency for international shoppers and preventing unexpected carrier fees upon delivery.
Top Cross-Border Solutions
- Zonos – Known for its robust API and compliance infrastructure, Zonos specializes in real-time landed cost calculations (duties, taxes, and fees), product HS code classification via AI, and localized international checkout experiences.
- Global-e – A comprehensive end-to-end internationalization platform that integrates directly with major e-commerce platforms to handle localized pricing, local payment methods, and guaranteed DDP duty/tax calculations at checkout.
- Easyship – A multi-carrier shipping software featuring a "Rates at Checkout" engine that calculates precise, country-specific import duties and taxes dynamically for platforms like Shopify, WooCommerce, and BigCommerce.
- Flow Commerce – An API-first cross-border solution tailored to give brands localized storefront capabilities, real-time duty and tax calculation feeds, and upfront payment options to boost international conversion rates.
Core Capabilities Offered
- Accurate Landed Cost Calculation: Instantly computes duties based on product HS codes, country of origin, and destination thresholds.
- Tax & Compliance Management: Monitors foreign tax registration thresholds and manages local indirect tax collection (such as VAT or GST).
- Localization Support: Translates currencies and displays the true total cost prior to payment authorization, reducing cart abandonment.
If you'd like to narrow this down, tell me:
- What e-commerce platform are you currently using (Shopify, Magento, custom API, etc.)?
- What are your primary target regions for international shipping?
I can help recommend the best-fit integration for your setup.
