Additional carrier fees 

It is important to be aware of other charges that can occur in addition to standard shipping costs. Additional charges such as fuel surcharges, out-of-area fees, residential surcharges, additional handling surcharges, and oversize fees may be charged in addition to shipping. Zonos' shipping calculations include these fees when applicable, which will ensure that you are being quoted the total landed cost and not losing money when shipping internationally.

Is Zonos tied to specific carriers?

No; we are a carrier-agnostic solution and will support any carrier(s) you use.

What is the difference between negotiated and incentivized shipping rates?

Negotiated rates are determined between you and your carrier(s), and are connected to Zonos via API. Whereas, incentivized rates are an additional option your carrier may offer. Incentivized rates are not passed to Zonos via API so you will need to contact our support team to enable account incentives.

What if I’m using a carrier other than UPS, FedEx, DHL, or USPS?

We can help you with that. Please contact your Customer Success rep for assistance.

Can I use Zonos Checkout for my domestic orders and shipping calculations?

Although Zonos was built specifically for cross-border and international transactions, many services and tools we provide have allowed retailers to offer a better checkout experience for their domestic customers.

Zonos has also helped these retailers manage complex shipping rules they were unable to handle with their existing shopping cart platform. If you feel like Zonos Checkout could also help with your domestic checkout experience, please contact us for further information.
