Multi-Carrier Shipping Software with Duties & Taxes Built In

Connect your own FedEx, UPS, DHL and USPS accounts to your ecommerce store, show live carrier shipping rates at checkout, and add the expected import duties and taxes next to each rate. Cross-border buyers see the real total landed cost before they pay, and you can ship DDP at your own negotiated rates.

What Is Multi-Carrier Shipping Software?

Multi-carrier shipping software connects your store to several carrier accounts at once, such as FedEx, UPS, DHL and USPS, and shows their live rates as shipping options at checkout. EdgeTariff adds the expected import duties and taxes to each option, so international buyers see the full landed cost before they pay.

Frequently asked questions

What is multi-carrier shipping software?

Multi-carrier shipping software connects your store to several carrier accounts at once, so a single integration returns rates and services from each of them. Instead of logging into separate carrier portals, you compare options, present them at checkout and hand the order off to the carrier your buyer picked.

How is multi-carrier shipping different from using one carrier?

With one carrier, buyers get one set of services and prices. With multi-carrier shipping, your checkout shows options from several carriers, such as FedEx, UPS, DHL and USPS, so buyers can choose speed or price, and you can switch carriers when one is late or expensive.

Which carriers does EdgeTariff integrate with?

EdgeTariff integrates with FedEx, DHL, UPS, USPS and SAIA, with Royal Mail and DPD coming soon. That covers domestic and international express, economy, post and LTL freight services. If you need a carrier that isn’t listed, the EdgeTariff API lets you bring expected duties and taxes into your own shipping setup.

How is EdgeTariff different from a normal multi-carrier shipping tool?

Most multi-carrier tools stop at the shipping rate. EdgeTariff adds Expected Duties & Taxes (EDT), so cross-border buyers see the landed cost of their order at checkout rather than being surprised by a customs bill on delivery.

Do I need my own carrier accounts?

Yes — you connect your own carrier accounts, so the rates your buyers see reflect the pricing you have negotiated with each carrier.

Can I create shipping labels with EdgeTariff?

Yes. You can create shipping labels for international orders in EdgeTariff using your connected carrier accounts, so rating, duties and taxes, and labels all happen in one place.

Can I ship DDP with my own carriers?

Yes. EdgeTariff collects the expected duties and taxes at checkout, so you can ship Delivered Duty Paid (DDP) with your own carrier accounts and the buyer pays nothing on delivery.

Does EdgeTariff support LTL freight?

Yes. Through the SAIA integration, heavier consignments can be quoted as LTL freight alongside your parcel carriers, with duties and taxes applied to cross-border orders.

Which ecommerce platforms are supported?

EdgeTariff ships plugins and apps for WooCommerce, Shopify, BigCommerce and Adobe Commerce (Magento). Any other stack can use the EdgeTariff API directly.

Is there an API and a sandbox?

Yes. The EdgeTariff API provides Expected Duties & Taxes for your own online store or other solutions, and a sandbox is available so you can build and test before going live.

Can I try it before committing?

You can start a free trial, or book a demo if you would rather be walked through carrier setup and landed-cost configuration first.

Does EdgeTariff support international shipping?

Yes. EdgeTariff shows live carrier rates with expected duties and taxes for 208+ countries, so international buyers see the full landed cost at checkout and you can ship DDP.
