What can shipping software with automatic customs calculation do?
Shipping software for international use goes far beyond simply printing shipping labels. According to OMR Reviews It combines a comprehensive platform offering tariff comparison, mass processing, label printing, and integrations with shop and ERP systems into a single, centralized solution. Automatic customs calculation is crucial for cross-border shipping.
Specifically, such a platform covers the following processes:
- Landed cost calculation: Shipping costs, import duties, VAT and other charges are automatically calculated for each destination country before the order is placed.
- Customs documents: Export accompanying documents, pro forma invoices and confirmations of arrival are automatically created, without manual data entry.
- Label printing and shipment tracking: Shipping labels are generated directly from the system; tracking data flows into a central dashboard.
- Returns management: Returns from abroad can be managed via the same platform, including customs clearance for returns.
Typical application scenarios: A B2B export order to Switzerland requires a customs declaration and proof of arrival. For marketplace sales to the USA or Australia, HS codes, import duties, and country-specific documentation requirements must be automatically taken into account. Shopify emphasizes that, especially in international sales, dynamic shipping calculations and correct customs clearance directly impact checkout quality.
How do you choose the best shipping software for international shipping?
A structured evaluation saves time and prevents costly mistakes. You should ask every provider the following ten questions:
- How does the system calculate Landed Costs, and which customs tables or data sources are used?
- Which carriers are natively connected, and can custom contract terms be integrated?
- Which ERP and shop system integrations are available (API, plugin, native connection)?
- How are HS codes maintained and updated?
- Which customs documents are generated automatically, and for which destination countries?
- What is the pricing model: pay-per-label, volume-based tariff or flat rate?
- What SLAs apply to support, and is there a dedicated customs contact person?
- How is GDPR compliance ensured, and where is data stored?
- What insurance options are available for international shipments?
- How long does a typical implementation take, and what internal resources are needed?
According to user reviews on G2, shipping software comparisons show that usability, integration depth, and quality of support are the three most frequently mentioned selection criteria.
Red flags indicating problems:
- Opaque fee structure: Surcharges only appear on the invoice, not in the offer.
- No access to proprietary carrier tariffs: The platform enforces exclusively centrally negotiated conditions, without the integration of proprietary contracts.
- Lack of customs document automation: Export accompanying documents must be created manually.
- No GDPR-compliant data storage in the EU.
Price models compared: Pay-per-label is suitable for fluctuating shipping volumes, as there are no fixed costs. Volume-based tariffs are worthwhile starting from a stable monthly volume. Individual price lists for each carrier allow for the most precise cost control. Check if hidden shipping surcharges are already included in the offer.
Pro tip: Check early on whether the platform enforces its own carrier tariffs or allows the integration of your own contracts. This directly impacts your cost control and contractual flexibility.

How does the implementation typically proceed?
Realistic planning prevents delays in the go-live. The process typically follows five phases:
| Phase | Time frame | Roles involved | Typical tasks |
|---|---|---|---|
| Discovery | 1-3 days | IT, Logistics, Purchasing | Requirements analysis, carrier inventory, HS code mapping |
| Integration | 3-10 days | IT, package international support | Set up API key, install plugin, link customs account |
| Testing | 2-5 days | Logistics, QA | Print test labels, check customs documents, test address validation |
| Go live | 1 day | All involved | Go-live, first real order |
| Follow-up | Constantly | Support, Logistics | KPI monitoring, carrier adjustments, document updates |
For the Shipment tracking dashboard It is recommended to set this up as early as the test phase so that KPIs can be measured from the first real shipment.
Key performance indicators for measuring success:
- Lead time per shipment (from order receipt to carrier handover)
- Cost per shipment compared to the previous process
- Percentage of correctly declared customs declarations
- Return rate for international shipments
Common pitfalls during international rollouts:
- Incomplete HS code database leads to customs delays.
- Address validation for non-EU countries is underestimated.
- Unclear contract terms with carriers are delaying the activation of our own tariffs.
- Lack of coordination between IT and logistics is prolonging the testing phase.
A solid one Tracking system This is relevant not only for customer communication, but also for internal error detection in customs problems.
