What Matters Most to You: Happy Customers
We help you delight your customers. Our fast processing ensures smooth delivery without burdening them with complex customs procedures. Thanks to our lean DDP customs clearance, parcels reach your customers fully cleared. This way, you enable a perfect customer journey with minimal costs and duties.
Maximum Efficiency for your Global Business
Simple Returns Processing
Easily re-clear returned goods. Our software links your outbound and inbound shipments, enabling straightforward returns declarations. Smooth and without customs duties on re-import.
No More Guesswork with Tariff Codes
Manually classifying thousands of SKUs is time-consuming and error-prone. Our AI learns your product catalog and automatically assigns the correct commodity codes to new items. This reduces delivery delays to a minimum and protects you from costly misclassifications.
Leverage Duty-Free Thresholds, Save on Customs Charges
By automatically submitting customs declarations at parcel level, we ensure you make full use of duty-free thresholds. With no customs charges incurred, you reduce your own costs and can offer attractive shipping prices to your customers – a real plus for their customer journey.
Automated Data Transfer Instead of Email Traffic
Manual transfer of invoice data is a thing of the past. With direct integration, you always stay up to date. Receive your declarations back into your system automatically within minutes. Fully relieve your operations from customs tasks – thanks to fully automated background processes. All from a single source.
