Our Verdict
The choice between Dr Cart Shipping Rates & Rules and Zonos Duty and Tax hinges entirely on the merchant's needs and business focus. For businesses solely operating within a single country and seeking to optimize their domestic shipping strategy with complex rules based on numerous factors, Dr Cart offers superior customization and control. Merchants can use Dr Cart to precisely tailor their shipping rates and incentivize purchases.
However, if a merchant is expanding internationally, particularly to regions with complex duty and tax regulations, Zonos becomes essential. Its ability to guarantee landed costs, handle VAT remittance, and provide compliant customs paperwork simplifies international expansion and reduces customer friction. While Dr Cart offers carrier integrations, it doesn't address the core issues of international duties and taxes that Zonos expertly manages. Therefore, merchants focused on global sales will find Zonos significantly more valuable.
Common Questions
Can Dr Cart calculate international duties and taxes?
Dr Cart primarily focuses on domestic shipping rules and rate calculations. While it can integrate with carriers that handle international shipments, it doesn't natively calculate or manage international duties and taxes.
Does Zonos work for domestic shipping within the US?
Zonos is primarily designed for international shipping and cross-border compliance. It's not optimized for domestic shipping scenarios within the US.
Which app is easier to set up and use?
Dr Cart may require more initial setup time due to the complexity of its rule engine, especially if you're using many parameters. Zonos setup might be quicker for international sellers who just need basic duty/tax coverage, as it focuses on that specific function. Consider your level of tech-savviness and how many rules you plan on creating as these factors will influence ease of use.
Can I use both Dr Cart and Zonos?
Yes, you can use both apps. Dr Cart can manage your domestic shipping rules, while Zonos handles the complexities of international duty, tax, and compliance. You would need to ensure the apps do not conflict in their carrier settings or pricing calculations to avoid customer confusion.
