Yes. ShipStation lets you compare rates across international carriers and services to find the best option for cross-border shipments. You’ll see rates from eligible carriers based on your package details and destination. Note that automated rate selection through Rate Shopper is currently available for domestic shipments, with international support coming in early 2026. How does Rate Shopper calculate delivery time? Rate Shopper estimates delivery using the time in transit from the business day after you ship. By default, that starts tomorrow. Only business days count—weekends are skipped. For example, a 2-business-day delivery starting Monday means your package arrives by Wednesday. Can you set service preferences with Rate Shopper? Yes. In Rate Shopoper, you can set up a Service Preference that will override the otherwise selected rate if your preferred service is only a certain amount more expensive. For example, if you have set your service preference to choose UPS Ground if the rate is within 1 dollar of the cheapest, it would select UPS Ground® if it were up to $0.99 more expensive than the cheapest rate. How much can I save using Rate Shopper? The possibilities are endless. Shippers save an average of 3.4% per label, automatically with Rate Shopper. Can I override Rate Shoppers selection if I need to? Absolutely. Rate Shopper suggests the best option based on your rules, but you always have final say. If you need to choose a different carrier or service for a specific order, you can override the selection before printing the label.
